Description

TER SL000167R Lower Cover for 4 Buttons

The TER SL000167R Lower Cover for 4 Buttons is a replacement lower enclosure component designed specifically for the 4-button TER NPA pendant control station. Supplied with tightening rubber and screws, the SL000167R provides a manufacturer-specific replacement solution for repairing, maintaining and refurbishing compatible NPA pendant control stations used throughout industrial lifting, material handling and machinery-control applications.

Industrial pendant control stations are frequently exposed to demanding working conditions. Regular handling, accidental impact, vibration, dirt, moisture and general mechanical wear can gradually affect the condition of the pendant enclosure. Where the lower section of a 4-button TER NPA pendant becomes cracked, damaged or otherwise unsuitable for continued service, the SL000167R allows the affected enclosure component to be replaced without automatically replacing the complete pendant control station.

TER identifies SL000167R specifically as the lower enclosure, tightening rubber and screws for the 4-button NPA pendant. Correct identification is important because the TER NPA range is available in several button configurations, with individual enclosure components assigned according to the size and construction of the pendant.

TER Part Number SL000167R

The manufacturer product reference for this replacement component is SL000167R.

Using the complete TER part number is important when ordering NPA enclosure spare parts because lower covers for different button configurations have their own individual references.

Maintenance departments, crane service organisations, OEMs and industrial equipment operators can record SL000167R within their spare-parts systems wherever compatible 4-button TER NPA pendant control stations are installed.

Lower Enclosure for the 4-Button TER NPA

The SL000167R forms the lower enclosure section of the 4-button TER NPA pendant control station.

As part of the complete pendant housing, the lower enclosure helps surround and mechanically protect the internal wiring, switches and associated control components while contributing to the physical structure handled by the operator.

Maintaining the enclosure in good condition is therefore an important part of maintaining the complete pendant control station.

Supplied with Tightening Rubber and Screws

TER specifies the SL000167R as a lower enclosure supplied with tightening rubber and screws.

The inclusion of these components provides the corresponding parts required for correct assembly of the replacement lower enclosure rather than requiring maintenance personnel to reuse unsuitable or damaged components from the existing housing.

Using the specified enclosure components helps preserve the intended mechanical arrangement of the TER NPA pendant.

Designed Specifically for the TER NPA

The SL000167R is designed for the TER NPA pendant control station in its 4-button configuration.

The NPA is an industrial pendant-control platform designed for auxiliary machine-control applications and can be configured with different numbers and types of actuators according to equipment requirements.

For the 4-button NPA version, SL000167R provides the corresponding lower enclosure replacement component.

Correct Pendant Identification Is Essential

Before ordering an SL000167R, the existing pendant should be positively identified as a 4-button TER NPA.

The pendant model, number of control positions and existing equipment documentation should be checked wherever possible.

This is particularly important at sites where several TER pendant sizes or product families are installed because enclosure components should not be selected purely on visual similarity.

Four-Button NPA Configuration

The 4-button NPA provides a compact operator-control arrangement suitable for machinery requiring a smaller number of commands.

Depending on the machine design, four control positions can accommodate combinations of lifting, lowering, travel, positioning or auxiliary functions.

The exact electrical and machine functions assigned to these positions depend on the individual equipment configuration.

Compact Pendant Control Solution

A four-button pendant can provide an efficient handheld control interface where the application does not require the additional control positions of larger NPA configurations.

Its compact format can be particularly useful for hoists, lifting equipment and machinery requiring a limited set of clearly arranged commands.

The SL000167R supports long-term maintenance of this compact NPA configuration.

Replacement Enclosure for Existing TER Equipment

The SL000167R is particularly useful when the lower enclosure of an existing 4-button NPA has been damaged but the remainder of the pendant remains suitable for continued service.

Rather than automatically replacing the complete control station, technicians can inspect the pendant and determine whether replacing the affected lower enclosure provides an appropriate repair.

This modular approach can help retain serviceable pushbuttons, switches, wiring and other pendant components.

Supporting Pendant Refurbishment

Industrial pendant stations can remain in service for extended periods when they are correctly maintained.

During that service life, enclosure components may experience more mechanical damage than internal electrical components because the housing is directly exposed to everyday handling and impact.

The availability of the SL000167R enables refurbishment of the lower section of compatible 4-button NPA pendants where replacement is appropriate.

Mechanical Protection for Internal Components

The pendant enclosure provides important physical protection for the electrical components installed inside the NPA.

Pushbutton contact elements, conductors and electrical connections should remain enclosed and protected during normal operation.

A cracked or damaged lower enclosure can compromise the physical integrity of the pendant and should therefore be inspected rather than treated as a purely cosmetic issue.

Damage from Everyday Industrial Use

Pendant controls are frequently moved and handled throughout the working day.

They may be carried between operating positions, suspended alongside machinery or repeatedly picked up and returned to a storage location.

Over time, this regular use can result in scratches, impact marks, worn fastening points or more significant enclosure damage.

Accidental Pendant Drops

Dropping a pendant is one potential cause of lower enclosure damage.

An impact with a floor or structure can produce cracking, deformation or damage around enclosure fastening locations.

Following a significant impact, the complete pendant should be inspected because damage may extend beyond the SL000167R lower enclosure to internal components, the cable entry or other housing sections.

Impact with Machinery and Structures

A suspended pendant can swing into machinery, structural steel, loads or nearby equipment during operation.

Repeated contact can gradually weaken the enclosure even where a single impact does not immediately produce obvious failure.

Routine visual inspection can help identify this type of deterioration before it develops into more extensive damage.

Cracked Lower Enclosures

Cracking is one of the clearest indications that a lower enclosure may require replacement.

Cracks can develop around edges, corners, screw locations or areas that have experienced direct impact.

Where the damage is confined to the lower enclosure of a compatible 4-button NPA, the SL000167R provides the appropriate TER replacement reference.

Damaged Fastening Points

The lower enclosure must be secured correctly to the adjoining pendant section.

If fastening points become cracked, distorted or otherwise damaged, the enclosure may no longer assemble securely.

Replacing the affected SL000167R component can restore the intended mounting arrangement provided the corresponding mating components remain in suitable condition.

Inspecting Enclosure Mating Surfaces

The surfaces where the lower enclosure meets the adjoining NPA section should remain clean, correctly aligned and free from significant damage.

Contamination, deformation or damaged edges can interfere with correct reassembly.

These areas should therefore be inspected before fitting the replacement SL000167R.

Importance of the Tightening Rubber

The tightening rubber supplied with the SL000167R forms part of the intended enclosure assembly.

It should be positioned correctly and inspected during installation to ensure it is not twisted, pinched, contaminated or damaged.

Correct positioning helps maintain the intended fit between the enclosure components.

Using the Supplied Screws

The screws supplied with the SL000167R provide the corresponding fastening components for installation of the lower enclosure.

Using the specified hardware avoids unnecessary reliance on improvised screws that may have unsuitable dimensions or characteristics.

Fasteners should be installed carefully and in accordance with the appropriate TER assembly and maintenance information.

Avoiding Excessive Tightening

Enclosure fasteners should be tightened correctly without applying unnecessary excessive force.

Overtightening can potentially damage fastening points or distort enclosure components, while insufficient tightening can leave the pendant poorly assembled.

If the enclosure does not fit together naturally, the cause of the misalignment should be investigated rather than forcing the components together.

Four-Button NPA Enclosure Components

The SL000167R forms part of the enclosure arrangement used for the 4-button TER NPA.

TER provides individual replacement references for the different sections and accessories used within the NPA family.

This modular construction allows maintenance personnel to identify and replace the affected enclosure component rather than automatically replacing the complete pendant.

Upper, Central and Lower Enclosure Sections

The NPA enclosure is constructed from multiple sections that work together to form the complete pendant housing.

The SL000167R provides the lower enclosure component for the four-button configuration, while the corresponding upper and central sections are separate TER spare parts.

Each section should be inspected following significant impact or enclosure damage.

Modular NPA Maintenance

The availability of separate enclosure components supports a modular approach to NPA pendant maintenance.

If only the lower housing section is damaged, technicians can assess whether replacing the SL000167R is sufficient while retaining the remaining serviceable components.

This can reduce unnecessary replacement and help preserve an established pendant configuration.

Maintaining the Original Operator Interface

Using the correct replacement enclosure helps retain the physical arrangement operators already know.

This can be valuable on cranes, hoists and machinery where the pendant layout, control symbols and operating procedures have remained established over many years.

Replacing the lower enclosure does not require changing the machine functions assigned to the existing controls.

Preserving Existing Internal Wiring

Where the pendant wiring remains in satisfactory condition, lower enclosure replacement may allow the existing electrical arrangement to remain largely undisturbed.

Care should still be taken during disassembly because internal conductors can be positioned close to enclosure surfaces.

Wiring should not be trapped, pinched or damaged when the SL000167R is installed.

Safe Isolation Before Replacement

The machine should be safely isolated before the NPA pendant is opened or enclosure components are removed.

A pendant can contain circuits associated with machine movement, so maintenance must account for both electrical hazards and the possibility of unexpected equipment operation.

Work should be performed by appropriately competent personnel following applicable machine and workplace isolation procedures.

Opening the Existing Pendant

Once the equipment has been safely isolated, the existing lower enclosure can be removed according to the applicable NPA maintenance procedure.

Care should be taken as the housing sections are separated because internal conductors and switching components may be positioned close to the enclosure.

Components should not be pulled apart forcibly if resistance indicates that wiring or another internal part is interfering.

Recording the Existing Wiring Arrangement

Before moving internal conductors, technicians can record the existing wiring arrangement using photographs, wire identification and machine documentation.

This provides a useful reference during reassembly.

Although a 4-button pendant is relatively compact, it can still contain multiple conductors and contact arrangements that should remain correctly identified.

Inspecting Internal Wiring

Opening the pendant for enclosure replacement provides an opportunity to inspect accessible wiring.

Conductors should be checked for damaged insulation, loose connections, excessive strain or other visible deterioration.

Any electrical defect identified during the repair should be addressed before the new enclosure is installed and the pendant returned to service.

Inspecting Pushbutton Components

The condition of the four pendant control positions should also be considered during refurbishment.

Pushbuttons should operate consistently according to their intended design and should not show excessive mechanical wear or damage.

A new lower enclosure should not be used to conceal defective or unreliable control components.

Inspecting Contact Elements

Electrical contact elements associated with the pendant actuators should remain secure and functional.

Intermittent operation may indicate a contact, terminal or wiring problem rather than an enclosure fault.

Functional testing after reassembly should confirm that each relevant control operates correctly.

Inspecting the Pendant Cable

The pendant cable is subjected to regular movement and flexing and should be included in the inspection process.

The outer sheath can be checked for cuts, abrasion, crushing or other deterioration, particularly near the point where the cable enters the pendant.

A damaged cable requires appropriate attention independently of the SL000167R enclosure replacement.

Four-Button NPA Cable Sleeve Arrangement

The four-button NPA belongs to the smaller 2-to-6-button NPA enclosure group for the applicable cable sleeve holder arrangement.

When servicing a four-button pendant, the cable entry and associated support components should be checked for correct condition and assembly.

Damage to the cable support arrangement can place unnecessary stress on internal conductors and terminals.

Inspecting Cable Strain Relief

The pendant cable should be supported so that external mechanical forces are not unnecessarily transferred to internal terminals or conductors.

Any strain-relief or cable-support components should remain mechanically secure.

Damage identified in this area should be addressed before the pendant returns to service.

Environmental Protection of the Complete NPA

TER specifies the correctly assembled NPA pendant control station with an IP65 degree of protection.

This rating applies to the complete pendant assembly rather than to the SL000167R lower enclosure considered as an isolated component.

Correct assembly of the enclosure sections, tightening rubber and cable-entry components is therefore important when maintaining the environmental protection of the complete NPA.

Understanding the IP65 Rating

The SL000167R should not be described as an independently IP65-rated product simply because it forms part of the NPA pendant enclosure.

The IP rating relates to the complete correctly assembled TER NPA configuration.

This distinction provides more accurate technical information when specifying the lower enclosure as an individual replacement component.

Protection Against Dust and Moisture

Industrial pendant stations can operate in environments where dust, dirt and moisture are present.

Maintaining the integrity of the complete enclosure helps protect internal electrical components from these external conditions.

Cracked covers, damaged enclosure joints or incorrectly assembled components should therefore be addressed during maintenance.

TER NPA Operating Temperature

TER specifies the complete NPA pendant control station for an operating temperature range of -25°C to +70°C.

This specification applies to the complete NPA product rather than representing an independent temperature rating for the SL000167R spare enclosure alone.

The lower enclosure supports maintenance of the NPA housing used within these industrial applications.

TER NPA Storage Temperature

TER specifies a storage temperature range of -40°C to +70°C for the complete NPA pendant control station.

As with the operating-temperature specification, this is a complete-product characteristic rather than a standalone certification of the SL000167R lower enclosure.

Replacement parts should nevertheless be stored appropriately and protected from unnecessary contamination, impact and environmental deterioration before installation.

Class II NPA Construction

TER specifies the complete NPA pendant control station as Class II equipment.

Replacement enclosure work should preserve the intended TER construction and should not introduce unauthorised modifications to the pendant housing.

The SL000167R should therefore be used for its specified NPA application rather than modified for unrelated control equipment.

Avoiding Unauthorised Enclosure Modifications

Drilling additional holes, cutting the housing or otherwise altering the SL000167R can affect the mechanical integrity and performance of the complete pendant assembly.

If a different control configuration is required, the appropriate TER pendant or enclosure configuration should be selected.

Modification should not be used as a substitute for correct product selection.

Crane Control Applications

The TER NPA pendant control station is suitable for industrial lifting applications where operators require a robust handheld interface for machine commands.

A 4-button configuration can provide a practical arrangement for crane or hoist movement functions depending on the electrical and mechanical design of the equipment.

The SL000167R supports maintenance of these installations by providing the corresponding lower enclosure spare.

Overhead Travelling Crane Applications

Overhead travelling crane pendants can experience intensive daily handling in manufacturing plants, workshops, warehouses and material-handling facilities.

Repeated movement and accidental contact with surrounding structures can eventually damage the pendant housing.

For a compatible 4-button NPA, SL000167R provides the TER lower enclosure replacement required for refurbishment.

Gantry Crane Applications

Gantry cranes can operate in demanding industrial environments where pendant controls may be exposed to frequent handling and mechanical impact.

Maintaining the condition of the pendant enclosure helps protect its internal components and preserve the operator interface.

The SL000167R is suitable for the corresponding 4-button NPA pendant configuration used in these applications.

Jib Crane Applications

Jib cranes commonly use compact pendant stations for local lifting and movement control.

A four-position pendant can provide an efficient arrangement where a limited number of machine commands are required.

Where the lower enclosure of a TER NPA becomes damaged, the SL000167R provides the correct replacement component for the 4-button version.

Hoist Applications

Hoists are a common application for industrial pendant control stations.

A 4-button NPA can provide commands for lifting, lowering and additional movement or auxiliary functions depending on the system design.

Replacing a damaged lower enclosure can help extend the service life of an otherwise functional hoist pendant.

Winch Applications

Winch systems can use pendant controls to provide local commands for winding, unwinding and associated machine functions.

Because these controls are frequently handled, their enclosure condition should form part of routine equipment inspection.

The SL000167R provides a manufacturer-specific spare for compatible 4-button TER NPA installations.

Stage Technology Applications

TER NPA pendant control stations can also be used within stage technology applications involving powered movement, hoists and winches.

Control equipment used in these environments should remain mechanically sound and clearly organised for the operator.

Replacement enclosure components such as the SL000167R support ongoing maintenance of established NPA installations.

Industrial Machinery Control

Beyond lifting equipment, 4-button pendant stations can provide local control for industrial machinery and material-handling systems.

The exact command arrangement is determined by the machine designer and may include movement, positioning or auxiliary functions.

The SL000167R provides enclosure support for the compatible TER NPA control station used within these systems.

Preventative Maintenance for NPA Pendants

The condition of the lower enclosure should be checked during routine pendant maintenance rather than only after complete failure occurs.

Small cracks, worn fastening locations or signs of repeated impact can provide early warning that replacement may soon be required.

Planned maintenance can help reduce the risk of an unexpected pendant failure interrupting equipment operation.

Reducing Unplanned Equipment Downtime

A damaged pendant can prevent an otherwise serviceable crane, hoist or industrial machine from operating.

Accurate spare-part identification helps maintenance teams source the correct enclosure component efficiently.

For installations using the 4-button TER NPA, SL000167R is an important lower enclosure reference to include within maintenance documentation.

Maintaining SL000167R as a Spare Part

Facilities operating several 4-button NPA pendants may choose to maintain an SL000167R within their spare-parts inventory.

The appropriate stock level depends on the number of installed pendants, equipment criticality, operating environment and maintenance history.

Holding the correct enclosure spare can be particularly useful where crane or production downtime has significant operational consequences.

Correct Spare-Part Description

For purchasing and maintenance systems, a useful description is “TER SL000167R Lower Enclosure with Tightening Rubber and Screws – NPA 4 Button.”

This description identifies the manufacturer, exact part number, component type and compatible pendant configuration.

Using detailed product identification helps avoid confusion with other TER NPA lower enclosure components.

SL000167R Versus SL000168R

The SL000167R should not be confused with TER SL000168R.

SL000167R is the lower enclosure for the 4-button NPA configuration, while SL000168R is specified for the 6-button NPA.

The number of control positions should therefore be confirmed before ordering.

SL000167R Versus SL000169R

TER SL000169R is the lower enclosure for the larger 8-button NPA configuration.

Although both components belong to the same NPA family and perform a similar structural function, they correspond to different pendant sizes.

SL000167R should be selected specifically for the 4-button NPA.

SL000167R and the 4-Button Central Section

The lower enclosure and central section are separate components within the four-button NPA housing.

The SL000167R should therefore not be confused with the corresponding central enclosure section.

Both components should be inspected if the pendant has experienced substantial impact or crushing.

Choosing the Correct NPA Lower Cover

Selection should be based on the TER pendant family, button configuration and exact spare-part reference rather than enclosure appearance alone.

For a confirmed 4-button TER NPA requiring a replacement lower enclosure, the correct reference is SL000167R.

This precise identification helps maintenance and purchasing teams avoid ordering a cover for the wrong pendant size.

Why Choose the TER SL000167R?

The TER SL000167R provides a manufacturer-specified replacement lower enclosure for the 4-button NPA pendant control station.

Its inclusion of tightening rubber and screws supports correct refurbishment, while the exact TER part number gives maintenance and purchasing teams a clear reference for spare-parts management.

For crane service companies, industrial maintenance departments, OEMs and system integrators, SL000167R provides a practical solution for repairing established TER NPA pendant installations.

TER SL000167R for Long-Term NPA Maintenance

The TER SL000167R Lower Cover for 4 Buttons supports the continued maintenance and refurbishment of compatible 4-button TER NPA pendant control stations.

By allowing a damaged lower enclosure to be replaced where the remaining pendant components are still suitable for service, the SL000167R can help preserve existing equipment, reduce unnecessary replacement and simplify long-term spare-parts support.

Correct identification, safe isolation, careful installation and complete functional testing are essential when returning a refurbished NPA pendant to service.

Understanding the Role of the SL000167R Lower Enclosure

The TER SL000167R lower enclosure performs an important structural role within the complete 4-button NPA pendant control station. Although the component does not perform an electrical switching function itself, it forms part of the protective housing surrounding the internal control components used by the machine operator.

The condition of the lower enclosure can therefore affect the overall physical integrity of the pendant. Cracking, deformation, damaged fastening points or poor enclosure fit should be investigated as part of normal maintenance rather than considered purely cosmetic damage.

Replacing a damaged lower enclosure with the correct SL000167R component supports restoration of the intended NPA housing arrangement while allowing suitable internal components to remain in service.

Protecting Internal Pendant Components

Inside a typical NPA pendant are electrical conductors, contact elements and other components associated with the installed actuators.

The enclosure helps protect these components from everyday mechanical contact and the industrial environment surrounding the pendant.

Maintaining the housing in good condition is therefore an important part of maintaining the complete operator-control station.

Mechanical Protection During Daily Operation

Industrial pendant stations can be handled hundreds of times during normal operation.

They may be carried around a work area, suspended alongside machinery, repositioned while following a load or repeatedly returned to a storage position.

The SL000167R forms part of the enclosure that must withstand this routine handling while supporting protection of the internal NPA components.

Recognising Lower Enclosure Damage

Damage requiring attention may include visible cracking, distortion, broken corners, damaged screw locations or sections that no longer align correctly with the adjoining housing.

Even relatively small defects should be assessed because enclosure damage can worsen through continued handling and vibration.

Where the defect is confined to the lower section of a compatible 4-button NPA, SL000167R provides the appropriate TER replacement reference.

Damage Following a Pendant Drop

A pendant that has been dropped onto a hard industrial floor should be inspected before continued operation if there is any indication of damage.

The lower enclosure may absorb part of the impact, but the force can also be transferred to pushbuttons, contact elements, cable components and other housing sections.

Replacement of the SL000167R should therefore be accompanied by an inspection of the complete pendant.

Damage from Swinging into Equipment

Suspended pendants can sometimes swing into crane structures, machinery, racking or other nearby equipment.

Repeated impact may initially produce only surface marks but can eventually contribute to cracking or weakening of the enclosure.

If this type of damage occurs frequently, the pendant operating and storage arrangement should also be reviewed.

Inspecting Corners and Edges

Corners and edges can receive significant impact during everyday use.

Maintenance personnel should inspect these areas for fine cracks, deformation or material loss.

Damage near an enclosure joint can be particularly important because it may interfere with correct mating between housing sections.

Inspecting Screw Locations

The fastening locations should remain intact so that the lower enclosure can be secured correctly.

Cracks or damaged mounting points can prevent the enclosure from being assembled as intended.

If the fastening areas of the existing lower cover are damaged, replacement with SL000167R may restore the correct arrangement provided the mating enclosure components are also serviceable.

Checking the Central Enclosure Section

Damage to the lower cover can sometimes be accompanied by damage to the adjoining central section.

The central enclosure should therefore be checked for cracking, deformation and damaged fastening locations before the new lower cover is installed.

A replacement SL000167R cannot correct damage located elsewhere within the pendant housing.

Checking the Upper Cover

The upper enclosure section should also be included in the inspection following a significant impact.

Damage may not always occur at the point where the pendant first contacted a surface.

Checking all housing sections helps determine whether individual component replacement or a broader refurbishment is appropriate.

Preparing the Pendant for Repair

Before the pendant is opened, the associated machine should be placed in an appropriate safe condition and isolated according to applicable procedures.

This is particularly important where pendant controls can command lifting or machine movement.

Maintenance work should be performed by personnel competent to service the relevant electrical and mechanical equipment.

Preventing Unexpected Machine Movement

Opening or working on a pendant while its control circuits remain active can create unnecessary risk.

Safe isolation helps prevent unexpected machine movement while conductors and switching components are being inspected or repositioned.

The applicable site isolation and lockout procedures should be followed before maintenance begins.

Removing the Existing Lower Enclosure

Once the equipment is safely isolated, the existing lower enclosure can be removed in accordance with the applicable TER NPA maintenance instructions.

The housing sections should be separated carefully so that internal wiring is not pulled or damaged.

If resistance is encountered, the technician should determine the cause rather than forcing the enclosure apart.

Inspecting the Existing Fasteners

The condition of the removed fasteners can provide useful information about previous maintenance.

Damaged screw heads, incorrect hardware or signs of excessive tightening may indicate that the pendant has previously been assembled incorrectly.

The screws supplied with the SL000167R provide the corresponding replacement hardware for the new lower enclosure.

Removing Dirt Before Reassembly

Dirt and contamination should be removed from enclosure mating areas before the replacement component is installed.

Clean surfaces make it easier to inspect for cracking and help the housing sections fit together correctly.

Cleaning methods should remain suitable for the enclosure materials and internal electrical components.

Positioning the Tightening Rubber

The tightening rubber supplied with the SL000167R should be positioned according to the intended enclosure arrangement.

It should sit correctly without twisting, folding or becoming trapped outside its intended location.

The component should also remain clean and free from damage before the pendant is closed.

Checking the Tightening Rubber Before Final Assembly

Before installing the screws, the technician should confirm that the tightening rubber remains correctly positioned around the relevant enclosure interface.

A displaced component can interfere with correct closure.

Correcting the position before tightening is preferable to forcing the housing together.

Using the Supplied TER Screws

The SL000167R is supplied with screws intended for installation of the replacement lower enclosure.

Using these components reduces the need to select generic fasteners and helps maintain the intended assembly arrangement.

The screws should be handled carefully to avoid damaging the fastening points during installation.

Avoiding Generic Replacement Screws

A generic screw that appears similar may have different thread characteristics, dimensions or head geometry.

Using unsuitable hardware can damage the enclosure or prevent correct assembly.

Where the specified screws are supplied with the SL000167R, they should be retained with the enclosure until installation.

Avoiding Cross-Threading During Installation

Each screw should engage correctly before significant tightening force is applied.

If a fastener does not enter smoothly, its alignment should be checked.

Forcing a misaligned screw can damage the new lower enclosure and create an avoidable maintenance problem.

Controlled Tightening of the Enclosure

The enclosure should be brought together evenly rather than using one fastener to pull a badly misaligned housing into position.

Fasteners should be tightened in a controlled manner using appropriate maintenance practices.

If a gap remains, the technician should inspect the enclosure alignment, tightening rubber and internal wiring before continuing.

Avoiding Enclosure Distortion

Excessive tightening can place unnecessary stress on the enclosure and fastening points.

The objective is secure assembly rather than maximum possible fastening force.

Correct installation helps maintain the intended fit between the SL000167R and adjoining NPA components.

Checking Internal Wire Routing

Before closing the pendant, all internal conductors should be checked to ensure they are clear of the enclosure joint.

A conductor trapped between housing sections can suffer insulation damage and may prevent correct enclosure closure.

Careful routing is therefore an important part of the refurbishment process.

Preventing Pinched Conductors

Pinched wiring can create electrical faults that were not present before the enclosure was replaced.

Conductors should have sufficient clearance from screw locations, moving actuator components and enclosure mating surfaces.

The internal arrangement should be checked before final tightening.

Maintaining Conductor Identification

Wire numbers, labels and terminal identification should be preserved wherever possible.

Clear identification simplifies future troubleshooting and helps technicians confirm that the original electrical arrangement has been maintained.

Missing or damaged identification can be restored according to the machine documentation where appropriate.

Using Photographs During Refurbishment

Photographs taken before internal components are moved can provide a useful reference during reassembly.

This is particularly helpful when several conductors are routed through a compact pendant enclosure.

Photographs should complement rather than replace accurate machine drawings and electrical documentation.

Inspecting Internal Terminals

Accessible terminals should be checked for looseness, damage, corrosion or signs of overheating.

A loose connection can produce intermittent operation even when the external enclosure appears satisfactory.

Any electrical defect identified during the repair should be corrected appropriately before the pendant is closed.

Inspecting Conductor Insulation

Electrical insulation should remain intact throughout the accessible wiring.

Cuts, abrasion, crushing or heat damage require investigation.

A replacement lower enclosure should only be installed after the technician is satisfied that the internal wiring remains suitable for continued service.

Signs of Electrical Overheating

Discolouration, melted insulation or heat-damaged terminals can indicate an electrical problem requiring further diagnosis.

Replacing the SL000167R does not resolve faults originating from overloaded, loose or damaged electrical connections.

The cause should be identified and corrected before recommissioning.

Inspecting for Moisture

Moisture found inside the pendant should be treated as an indication that the complete enclosure and cable-entry arrangement requires inspection.

The source may be unrelated to the lower cover itself.

Possible causes should be addressed before the pendant is reassembled.

Inspecting for Industrial Contamination

Dust, oil, dirt and other contamination can enter a damaged pendant or accumulate during previous maintenance.

Contaminants should be removed using methods appropriate for the materials and electrical components involved.

The source of recurring contamination should also be investigated.

Inspecting the Four Control Positions

The four actuator positions should be inspected while the enclosure is open.

Each control should remain securely mounted and mechanically sound.

Any abnormal movement, cracking or looseness should be investigated before the pendant is reassembled.

Checking Pushbutton Movement

Pushbuttons should move according to their intended design without sticking or binding.

If an actuator feels abnormal, the cause may involve the actuator itself, its mounting or the associated switching component.

The problem should be corrected rather than assuming enclosure replacement will resolve it.

Inspecting Contact Elements

The contact elements associated with the installed controls should remain properly secured.

Where a machine command has been intermittent, the contact elements and terminals should be included in fault diagnosis.

Functional testing should confirm reliable operation after reassembly.

Inspecting Any Emergency-Stop Device

If the specific NPA configuration incorporates an emergency-stop control, it should be inspected and tested according to the applicable machine safety procedure.

The SL000167R is an enclosure component and does not itself provide an emergency-stop function.

Safety-related control performance must therefore be verified independently following maintenance.

Inspecting Any Selector Controls

Where selector switches or other actuator types are fitted to the pendant, their mechanical operation should also be checked.

They should remain securely installed and operate through their intended positions.

The exact actuator arrangement depends on the individual machine configuration.

Inspecting the Pendant Cable

The pendant cable should be examined as part of the same maintenance activity.

Its outer sheath should be checked for cuts, crushing, abrasion and splitting.

Particular attention should be given to areas experiencing frequent flexing or movement.

Inspecting the Cable Near the Pendant Entry

The section of cable immediately adjacent to the pendant can experience repeated bending during operation.

Deterioration in this area may eventually affect internal conductors.

Visible cable damage should be addressed independently of the lower enclosure replacement.

Checking the Cable Support Arrangement

The cable should be supported so that external loads are not unnecessarily transferred to internal electrical terminals.

Any cable sleeve, holder or strain-relief arrangement should remain mechanically secure.

Damage should be corrected before the pendant returns to service.

Intermittent Cable Faults

A damaged conductor within the pendant cable can sometimes produce an intermittent machine command that changes as the cable moves.

This type of fault may be mistaken for a defective pushbutton.

Where intermittent operation is reported, the cable should form part of the diagnostic process.

Inspecting the Cable Entry for Contamination

The cable-entry area should remain clean and correctly assembled.

Accumulated dirt or damage can indicate that additional maintenance is required.

The condition of the complete entry arrangement contributes to the integrity of the assembled pendant.

Maintaining the Complete NPA Enclosure

TER specifies IP65 protection for the complete correctly assembled NPA pendant control station.

The SL000167R is one component within this enclosure system and should not be represented as independently providing the complete IP65 rating.

Correct installation and condition of all enclosure and cable-entry components are important to the complete assembly.

Checking the Enclosure Joint After Installation

Once the lower cover has been fitted, the joint between enclosure sections should be inspected around its full perimeter.

The housing should appear evenly assembled without visible gaps or displaced components.

Any irregularity should be investigated before the pendant is returned to operation.

Checking for Trapped Tightening Rubber

The tightening rubber should not protrude unexpectedly from the enclosure joint.

Visible displacement may indicate that it has moved during assembly.

The pendant should be reopened and the component repositioned if necessary rather than accepting an incorrectly assembled joint.

Checking Screw Seating

The supplied screws should sit correctly after installation.

Damaged screw heads, unusual angles or incomplete seating can indicate a fastening problem.

Any such issue should be corrected before functional testing begins.

Mechanical Inspection After Reassembly

The complete pendant should feel mechanically secure when handled.

There should be no unintended movement between enclosure sections.

The cable entry and installed actuators should also remain securely mounted.

Functional Testing After SL000167R Installation

After mechanical reassembly, the pendant should undergo appropriate functional testing.

This confirms that internal wiring and switching components were not disturbed during the enclosure repair.

The machine should remain under controlled conditions throughout testing.

Testing All Four Control Positions

Each relevant control position should be operated and checked for the expected response.

Testing all four positions helps identify any connection or actuator issue introduced or discovered during refurbishment.

Unexpected behaviour should be investigated before the pendant returns to normal service.

Testing Opposing Movement Commands

Many lifting applications use paired commands such as raise and lower or forward and reverse.

Where these functions are present, each command should be verified individually.

The operator interface should correspond correctly with the resulting machine movement.

Testing Auxiliary Commands

If one or more control positions operate auxiliary machine functions, these should also be included in recommissioning tests.

The exact function depends on the machine’s electrical design.

Every control affected by the pendant should be confirmed before release to normal operation.

Testing Under Controlled Conditions

Initial machine testing should be performed under conditions that allow unexpected behaviour to be managed safely.

Personnel should follow the site’s commissioning and maintenance procedures.

The pendant should not be returned to production use until testing is complete.

Testing Safety-Related Functions

Any safety-related control incorporated into the pendant should be tested according to the relevant machine safety procedure.

Replacing the lower enclosure does not demonstrate that a safety function remains effective.

Required functional checks should therefore be completed independently.

Documenting the SL000167R Repair

The replacement can be recorded within the machine’s maintenance history using the exact TER part number SL000167R.

The reason for replacement, repair date and pendant or machine identification can also be documented.

Accurate records support future fault diagnosis and spare-parts planning.

Monitoring Repeat Enclosure Damage

If the same pendant requires repeated lower cover replacement, maintenance records can help identify the pattern.

Recurring damage may indicate frequent impact, unsuitable storage, cable stress or harsh operating conditions.

Correcting the underlying cause may extend the service life of future replacement components.

Reviewing Pendant Storage

The pendant should have a suitable position when the equipment is not being operated.

Leaving it on the floor or against moving equipment increases the possibility of crushing and impact damage.

A consistent storage arrangement can reduce unnecessary wear.

Reducing Swinging and Collision Damage

Where a suspended pendant frequently strikes nearby structures, the installation and operating practices should be reviewed.

Reducing repeated impact can help protect the enclosure, actuators and internal components.

Any changes should remain compatible with the machine’s intended design and safe operation.

Operator Handling Practices

Careful handling can significantly influence pendant service life.

The control station should not be thrown, intentionally dropped or used to pull machinery.

The cable should also not be used as an inappropriate lifting or pulling handle.

Routine Visual Inspection

A quick visual inspection can identify developing problems before the pendant fails completely.

Operators and maintenance personnel can look for cracks, loose enclosure sections, damaged cables and abnormal controls.

Any defect should be reported and assessed according to site procedures.

Scheduled NPA Maintenance

More detailed pendant inspection can be incorporated into scheduled crane, hoist or machinery maintenance.

The appropriate frequency depends on equipment usage, operating conditions and applicable maintenance requirements.

High-use pendant stations may justify more frequent inspection.

SL000167R for Crane Maintenance Workshops

Crane maintenance workshops can identify SL000167R as a dedicated spare for four-button TER NPA pendant repairs.

Recording the exact reference reduces time spent identifying similar enclosure components.

This can help improve repair turnaround and spare-parts accuracy.

SL000167R for Hoist Service

Hoist service organisations often maintain equipment from multiple sites and manufacturers.

Using the complete TER part number provides a reliable method for identifying the required lower enclosure.

For a confirmed four-button NPA, the correct reference is SL000167R.

SL000167R for Industrial Maintenance Departments

Industrial sites operating TER NPA pendants can include SL000167R within their internal spare-parts catalogue.

This can be particularly useful where several identical four-button pendant stations are installed.

Stocking decisions should reflect equipment criticality and maintenance history.

SL000167R for OEM Spare-Parts Support

OEMs can identify SL000167R within equipment manuals and aftermarket spare-parts documentation where a 4-button TER NPA has been supplied.

This gives end users a precise replacement reference for future enclosure maintenance.

Clear documentation can improve the long-term serviceability of the machine.

SL000167R for System Integrators

System integrators can use the SL000167R when refurbishing compatible existing NPA pendant installations.

Where the original control arrangement remains appropriate, replacing the lower enclosure allows the established operator interface to be retained.

Changes to machine control functions should be engineered separately from the enclosure repair.

Repairing Rather Than Automatically Replacing

A damaged lower enclosure does not necessarily mean that the complete pendant must be discarded.

If the remaining housing, cable, wiring and switching components are serviceable, replacing the SL000167R may provide an appropriate repair.

The decision should be based on inspection of the complete control station.

When Individual Enclosure Replacement Makes Sense

Individual replacement is particularly practical where damage is localised to the lower cover and the pendant otherwise operates reliably.

This allows serviceable components to remain in use while restoring the damaged enclosure section.

Functional testing is still required before recommissioning.

When Broader Refurbishment Is Appropriate

If the pendant also contains worn actuators, damaged wiring or deteriorated cable components, additional refurbishment may be appropriate.

Completing several necessary repairs during one maintenance event can reduce repeated downtime.

All replacement components should be correctly matched to the NPA configuration.

When Complete Pendant Replacement Should Be Considered

Where the enclosure is extensively damaged and multiple electrical components are also deteriorated, replacing the complete pendant may be more practical than rebuilding it component by component.

Maintenance cost, equipment criticality and expected remaining service life should be considered.

The objective should always be a reliable and correctly configured control station.

Maintaining the Original TER Configuration

Using SL000167R helps preserve the original physical configuration of the four-button TER NPA.

This can be useful where the machine documentation, operator training and spare-parts systems are already based around the existing pendant design.

A correctly selected replacement enclosure supports consistent long-term maintenance.

Accurate Purchasing Information

Purchasing documentation should include the complete TER reference SL000167R and identify the component as the lower enclosure for the 4-button NPA.

A generic description such as “TER lower pendant cover” may not provide enough information to distinguish between different NPA sizes.

Exact product identification helps reduce ordering errors.

Recommended Ordering Description

A suitable purchasing description is “TER SL000167R Lower Enclosure for 4-Button NPA Pendant, with Tightening Rubber and Screws.”

This clearly identifies the manufacturer, component, compatible pendant and supplied hardware.

The TER part number should remain the primary ordering reference.

Supporting Reliable NPA Refurbishment

Successful pendant refurbishment involves more than simply replacing the visible damaged component.

Correct part identification, safe isolation, inspection of internal components, careful reassembly and complete functional testing all contribute to a reliable result.

The SL000167R provides the appropriate TER lower enclosure component for this process on a compatible four-button NPA.

TER SL000167R as a Maintenance Spare

The TER SL000167R provides maintenance departments, crane service companies, hoist specialists, OEMs and system integrators with a precise spare-part solution for the 4-button NPA pendant.

Supplied with tightening rubber and screws, it supports repair of damaged lower enclosure sections while allowing suitable existing pendant components to remain in service.

Correctly stocked, identified and installed, the SL000167R can form an important part of long-term TER NPA maintenance and refurbishment programs.

Industrial Applications for the TER SL000167R

The TER SL000167R Lower Cover for 4 Buttons supports maintenance and refurbishment of compatible TER NPA pendant control stations used across industrial lifting, material-handling and machinery-control applications.

Because pendant control stations are handled frequently and can be exposed to repeated movement, accidental impact and environmental contamination, enclosure components may require replacement even where the internal controls remain serviceable.

The SL000167R provides the correct TER lower enclosure reference for the 4-button NPA configuration.

Overhead Crane Applications

Overhead travelling cranes commonly use pendant control stations to provide direct operator control of lifting and travel functions.

A 4-button pendant can support paired movement commands such as raise and lower or forward and reverse, depending on the crane design.

Where the lower enclosure of a TER NPA pendant becomes damaged, the SL000167R allows the affected section to be replaced while retaining serviceable internal components where appropriate.

Gantry Crane Applications

Gantry cranes often operate in industrial environments where pendant controls are exposed to repeated handling and possible contact with structures or equipment.

Maintaining the physical condition of the enclosure helps preserve the integrity of the complete control station.

The SL000167R provides the correct lower enclosure replacement for compatible 4-button NPA pendants used in these applications.

Jib Crane Applications

Jib cranes frequently use compact pendant stations for local lifting and movement control.

A four-position pendant can provide a practical operator interface where a limited number of commands are required.

Where the lower section becomes cracked or damaged, SL000167R provides the manufacturer-specified replacement component for the 4-button NPA.

Hoist Applications

Industrial hoists are a common application for pendant control stations.

Depending on the system design, a 4-button NPA may provide commands for lifting, lowering and additional movement or auxiliary functions.

Replacing a damaged SL000167R lower enclosure can help extend the service life of an otherwise functional hoist pendant.

Winch Applications

Winch systems can use pendant controls to provide local commands for winding, unwinding and related machine functions.

These pendants may be handled repeatedly and exposed to mechanical wear throughout their service life.

For compatible 4-button TER NPA installations, the SL000167R provides a practical enclosure spare for repair and refurbishment.

Stage Technology Applications

TER NPA pendant control stations can also support stage technology applications involving powered movement, hoists and winches.

In these environments, reliable handheld controls are important for equipment setup, positioning and operation.

Maintaining a sound enclosure helps preserve the usability and condition of the complete control station.

Industrial Machinery Applications

Beyond lifting equipment, four-button pendant stations can be used for local control of industrial machinery and process equipment.

The exact functions assigned to the four positions depend on the machine design and control architecture.

The SL000167R supports maintenance of the enclosure used within compatible TER NPA installations.

Material Handling Applications

Material-handling systems can require simple and direct movement commands within one operator interface.

A 4-button pendant provides a compact control format for applications where only a limited number of operator functions are required.

Where enclosure damage occurs, the SL000167R provides the appropriate lower cover replacement for the corresponding NPA configuration.

Maintenance Workshop Applications

Industrial maintenance workshops servicing cranes, hoists and machinery can identify SL000167R as a known spare for four-button NPA pendant repairs.

Accurate part-number identification allows technicians to prepare the required enclosure component before beginning refurbishment work.

This can help reduce delays associated with identifying damaged pendant parts.

Crane Service Company Applications

Crane service organisations may work across fleets containing several TER pendant models and button configurations.

Using the exact SL000167R reference helps distinguish the four-button NPA lower enclosure from similar-looking TER components.

This supports efficient purchasing, inventory management and field servicing.

Hoist Service Company Applications

Hoist service companies can encounter a wide variety of pendant station configurations across customer sites.

Recording the TER part number SL000167R provides a precise reference for the 4-button NPA lower enclosure.

This reduces the risk of ordering a cover intended for another pendant size or family.

OEM Aftermarket Support

Original equipment manufacturers that have supplied machinery using a 4-button TER NPA can include SL000167R within their aftermarket spare-parts documentation.

This gives end users a clear replacement reference if enclosure damage occurs later in the machine’s service life.

Accurate documentation supports long-term equipment serviceability.

System Integrator Support

System integrators maintaining or upgrading machinery fitted with TER pendant controls can use SL000167R during refurbishment of compatible NPA stations.

Where the original pendant arrangement remains suitable, replacing the damaged lower enclosure can preserve the established operator interface.

Any changes to the electrical control system should remain separately engineered and documented.

Preventative Maintenance Programs

The lower enclosure should be included in routine preventative maintenance inspections.

Technicians can check for cracks, deformation, damaged fastening points and signs of repeated impact.

Identifying deterioration early can make it possible to schedule replacement before the pendant becomes unusable.

Daily Operator Inspection

Operators can assist with pendant maintenance by noticing visible defects before use.

Cracks, loose enclosure sections, damaged cables or controls that feel abnormal should be reported promptly.

Early reporting can help prevent minor damage from developing into a larger fault.

Inspecting for Repeated Impact

Scuffing and impact marks can indicate that the pendant is repeatedly striking nearby machinery or structures.

Even if the enclosure has not yet cracked, repeated contact can shorten its service life.

The pendant’s operating and storage arrangements should be reviewed where recurring impact damage is observed.

Improving Pendant Storage

A designated storage position can help protect the pendant when machinery is not in use.

The pendant should be kept away from areas where it could be crushed, struck by moving loads or damaged by vehicles and equipment.

Good storage practices can extend the service life of the SL000167R and the complete pendant.

Reviewing Cable Length and Position

Poor cable positioning can contribute to repeated enclosure impact and unnecessary stress on the pendant.

If the control station regularly drags across surfaces or swings into nearby equipment, the installation arrangement may deserve review.

Any changes should remain appropriate for the machine design and operating requirements.

Reducing Operator-Induced Damage

Operators should avoid using the pendant or its cable as a handle for moving equipment.

The control station should also not be thrown, dropped intentionally or subjected to unnecessary force.

Careful handling can significantly reduce mechanical wear on the enclosure.

Cleaning the SL000167R Lower Enclosure

The exterior of the lower enclosure can be cleaned as part of routine pendant maintenance using methods appropriate for the complete NPA assembly.

Cleaning should remove dirt and contamination without damaging enclosure materials, seals, labels or electrical components.

Aggressive chemicals should be avoided unless their suitability has been confirmed.

Cleaning Around Enclosure Joints

Dirt and contamination can accumulate around enclosure joints and fastening points.

Keeping these areas clean helps make developing cracks and other damage easier to identify.

Cleaning methods should not force contaminants or moisture into the pendant interior.

Inspecting for Chemical Exposure

Some industrial environments expose pendant controls to oils, cleaning agents and process chemicals.

Unusual softening, discolouration or surface deterioration can indicate that the enclosure has been affected by chemical exposure.

Where this occurs repeatedly, the operating environment should be reviewed as part of the maintenance process.

Inspecting for Heat Damage

Warping, abnormal discolouration or deformation can indicate that the pendant has been exposed to excessive heat.

The source of the heat should be investigated before a replacement SL000167R is installed.

Replacing the enclosure without correcting the underlying cause may result in repeated damage.

Inspecting for Outdoor Environmental Wear

Where pendant controls are used outdoors, long-term exposure to environmental conditions can contribute to material ageing.

Surface deterioration, brittleness and cracking should be monitored during routine inspection.

Replacement may be appropriate where this deterioration affects the mechanical condition of the lower enclosure.

Inspecting Fastening Points During Service

The screw locations used to secure the lower enclosure should remain intact and mechanically sound.

Cracking, damaged threads or excessive wear can interfere with correct assembly.

Any such condition should be addressed before the pendant is returned to service.

Inspecting the Tightening Rubber Over Time

Rubber components can deteriorate through age, contamination and repeated disassembly.

The tightening rubber should therefore be inspected whenever the pendant is opened.

The new component supplied with SL000167R supports correct replacement during refurbishment.

Inspecting the Screws After Installation

Fasteners should remain correctly seated during normal operation.

If screws repeatedly loosen, the underlying cause should be investigated rather than relying on repeated retightening.

Possible causes may include vibration, damaged fastening points or incorrect assembly.

Refurbishing an Older 4-Button NPA

An older pendant may benefit from a broader refurbishment when the SL000167R lower enclosure is replaced.

This can include inspection of pushbuttons, contact elements, the cable entry, internal wiring and other enclosure sections.

Addressing several developing issues during one planned repair can improve long-term reliability.

Replacing Multiple Worn Components

Where several pendant components are approaching the end of their useful service life, replacing them during one scheduled maintenance event can be more efficient than repeated individual repairs.

The SL000167R can form part of a wider refurbishment package for the four-button NPA.

The complete pendant should be functionally tested after all maintenance work is complete.

Maintaining the Original Pendant Layout

Using the correct TER lower enclosure helps retain the physical arrangement already familiar to operators.

This can be valuable on machinery where control positions, symbols and operating procedures have remained established for many years.

A like-for-like enclosure repair avoids unnecessary changes to the operator interface.

Supporting Existing Electrical Documentation

Machine drawings and spare-parts lists are often based on the original pendant configuration.

Using SL000167R as the correct lower enclosure for the four-button NPA helps keep the physical equipment aligned with these records.

This can simplify future fault finding and maintenance.

Maintaining Spare-Part Standardisation

Sites operating several identical TER NPA pendants can benefit from standardised spare-parts inventories.

Recording SL000167R for all compatible four-button installations allows maintenance and purchasing teams to use one common replacement reference.

This can reduce ordering errors and unnecessary duplication of stock.

Spare-Part Labelling

Stored SL000167R components should be clearly identified with the TER part number and intended application.

A description such as “4-button NPA lower enclosure” helps distinguish the part from covers used on other NPA sizes.

The tightening rubber and screws should remain with the enclosure until installation.

Spare-Part Storage Conditions

Replacement enclosure components should be stored in a clean, dry area where they are protected from impact and contamination.

They should also be kept away from excessive heat and conditions that could affect the supplied rubber component.

Appropriate storage helps ensure the complete replacement assembly is ready for use when required.

Inventory Planning for Critical Equipment

Where a 4-button NPA is used on production-critical lifting equipment, holding an SL000167R in stock may help reduce downtime following accidental enclosure damage.

The appropriate stock level depends on the number of installed pendants and the operational consequences of equipment downtime.

Maintenance history can also help determine whether the component should be held locally.

Ordering by Exact TER Part Number

The most reliable way to identify the product is by the complete TER part number SL000167R.

Generic descriptions such as “four-button pendant cover” can be ambiguous because several TER pendant families and enclosure sizes are available.

The exact part number should therefore remain the primary purchasing reference.

Confirming the NPA Pendant Family

Before ordering, the existing pendant should be confirmed as a TER NPA.

Other TER pendant families may use different enclosure components even where the number of control positions appears similar.

Correct model identification helps prevent unsuitable part selection.

Confirming the Four-Button Configuration

The pendant should also be confirmed as the four-button version.

TER uses separate lower enclosure references for different NPA sizes.

Checking the button count and available machine documentation helps ensure SL000167R is the correct replacement.

SL000167R Versus Six-Button NPA Covers

The four-button SL000167R should not be substituted with a lower enclosure intended for a six-button NPA.

The six-button version uses TER SL000168R.

The correct component should always be selected by part number and configuration.

SL000167R Versus Eight-Button NPA Covers

The 8-button NPA uses SL000169R rather than SL000167R.

Although both parts perform a similar structural role, they correspond with different pendant sizes.

Visual similarity should not be used as the sole basis for selection.

Fault Diagnosis Before Replacing the Enclosure

If the pendant is malfunctioning, technicians should determine whether the lower enclosure is actually related to the fault.

Electrical problems may originate from pushbuttons, contacts, internal wiring or the pendant cable.

Accurate diagnosis prevents unnecessary enclosure replacement.

When the SL000167R Is the Appropriate Repair

SL000167R replacement is particularly suitable where the lower enclosure is cracked, broken or mechanically damaged while the remainder of the pendant remains in satisfactory condition.

In this situation, the enclosure can be replaced without unnecessary replacement of serviceable internal components.

The complete pendant should still be inspected and tested after repair.

When Electrical Faults Are Also Present

If electrical defects are discovered during enclosure replacement, they should be corrected before reassembly.

Examples can include loose terminals, worn contact elements, damaged conductors or cable faults.

The objective should be to return a fully reliable control station to service.

When Contamination Is Found Inside

Internal moisture, dirt or contamination should be investigated rather than simply removed and ignored.

The source may involve another enclosure section, cable entry deterioration or previous incorrect assembly.

Correcting the underlying issue helps reduce the likelihood of repeated contamination.

When Multiple Enclosure Sections Are Damaged

If the upper cover, central section and lower enclosure are all significantly damaged, individual SL000167R replacement may not provide the most practical repair.

A broader refurbishment or complete pendant replacement may be more appropriate.

The overall condition of the NPA should guide the maintenance decision.

When the Pendant Cable Is Severely Damaged

Severe cable damage requires its own corrective action.

The cable forms part of the electrical connection between the pendant and machine control system and must remain mechanically and electrically sound.

A new lower enclosure cannot compensate for an unsafe or unreliable control cable.

When Pushbuttons Are Heavily Worn

An older pendant may contain several actuators or contact elements showing significant wear.

Where widespread deterioration is present, a more complete refurbishment may provide a better long-term result than replacing only the lower enclosure.

Maintenance decisions should consider reliability, equipment criticality and expected remaining service life.

Recommissioning After SL000167R Replacement

Once the new lower enclosure has been installed and the pendant fully reassembled, the control station should be recommissioned carefully.

Mechanical and electrical checks should confirm that the repair has not introduced any new faults.

The pendant should not return to normal operation until satisfactory testing has been completed.

Testing the Mechanical Assembly

The enclosure should be inspected to confirm that all sections fit together securely.

There should be no visible gaps, loose components or trapped wiring.

The cable entry and fastening points should also remain mechanically sound.

Testing Pushbutton Operation

Each of the four control positions should operate freely without rubbing against the enclosure or adjacent components.

Any stiffness or inconsistent movement identified after reassembly should be investigated.

The enclosure should not interfere with normal actuator operation.

Testing Electrical Operation

Each relevant pendant command should be tested to confirm correct electrical operation.

This is particularly important if internal conductors were moved during enclosure replacement.

Missing, intermittent or unexpected signals should be resolved before machine operation resumes.

Testing Crane and Hoist Movements

Where the pendant controls lifting equipment, movement commands should be tested according to the site’s established safe commissioning procedure.

Each control should correspond with the expected machine movement.

Testing should take place under controlled conditions where unintended movement can be managed safely.

Testing Safety-Related Controls

If the NPA contains an emergency-stop or other safety-related control, it should be tested separately according to the applicable machine safety procedure.

Physical enclosure replacement does not itself confirm correct safety-system operation.

The equipment should not be released for service until all required checks are complete.

Recording the Repair

Maintenance records should identify SL000167R as the replacement component installed.

The date of repair, reason for replacement and machine or pendant identification can also be documented.

This information provides useful service history for future maintenance and spare-parts planning.

Tracking Lower Enclosure Service Life

Recording replacement dates can help maintenance teams understand how long pendant enclosures typically remain in service under site conditions.

Frequent replacement may indicate unusually harsh handling or environmental exposure.

This information can support improvements in maintenance and operator practices.

Supporting Long-Term Equipment Reliability

Pendant control stations are relatively small components within a larger machine system, but their condition directly affects the operator’s ability to control equipment.

Maintaining enclosure integrity helps preserve the control components and supports reliable operation.

The SL000167R contributes to this objective for compatible 4-button TER NPA pendants.

Reducing Avoidable Downtime

A damaged pendant can take an otherwise operational crane, hoist or machine out of service.

Identifying the correct enclosure spare in advance can reduce repair time.

For equipment using the 4-button NPA, SL000167R is therefore a useful component to include in maintenance planning.

Supporting Sustainable Equipment Maintenance

Replacing an individual damaged enclosure component can sometimes avoid discarding a complete pendant that still contains serviceable switches, wiring and other parts.

This modular repair approach can extend the useful life of existing equipment and reduce unnecessary replacement.

The suitability of refurbishment should always be confirmed through inspection.

Control Devices Support for TER NPA Spare Parts

Control Devices supplies TER pendant control stations and associated replacement components for industrial lifting and machinery applications.

Customers maintaining an existing four-button NPA can use the TER part number and pendant configuration to identify the appropriate spare part.

Clear model information and photographs can assist with accurate component selection where required.

For crane and hoist servicing, accurate pendant spare-part identification can simplify refurbishment and reduce unnecessary equipment replacement.

This can include enclosure components, pushbuttons, contact elements, cable-entry parts and other TER NPA spares.

Using the correct components helps preserve the intended pendant configuration.

Support for Existing NPA Installations

Established TER NPA pendant stations may remain in service for many years when maintained correctly.

SL000167R provides the specific lower enclosure reference for the four-button version.

Where additional damage is present, the complete pendant configuration should be assessed before ordering further components.

Support for OEM and Retrofit Projects

OEMs and system integrators can use TER NPA components when supporting existing machine designs and refurbishment projects.

Where the original four-button pendant arrangement remains appropriate, replacing the SL000167R lower enclosure can help preserve the existing operator interface.

Any changes to machine controls should remain appropriately engineered and documented.

Information to Provide When Ordering

When ordering the TER SL000167R, customers should provide the complete part number and confirm that the existing pendant is a 4-button TER NPA.

If the configuration is uncertain, photographs and information from the existing pendant can assist with identification.

This is particularly useful at sites using multiple TER pendant models.

Recommended Purchasing Description

A clear purchasing description is “TER SL000167R Lower Cover for 4-Button NPA Pendant, including Tightening Rubber and Screws.”

This identifies the exact manufacturer component, pendant family and configuration.

The TER part number SL000167R should remain the primary ordering reference.

Why Choose the TER SL000167R Lower Cover?

The TER SL000167R provides the correct manufacturer-specified lower enclosure for compatible 4-button NPA pendant control stations.

It supports repair of damaged pendant housings while allowing serviceable internal components to remain in use where appropriate.

A Practical Spare for Industrial Maintenance

For maintenance teams responsible for cranes, hoists, winches and industrial machinery fitted with TER NPA pendants, SL000167R is a useful enclosure spare to identify.

Keeping the exact TER reference within maintenance documentation can reduce ordering uncertainty and help shorten repair times.

This can be particularly valuable where equipment downtime affects production or lifting operations.

Supporting Long-Term TER NPA Service

The modular construction of the TER NPA pendant allows individual enclosure components to be replaced where the overall station remains suitable for continued service.

The SL000167R supports this long-term maintenance strategy by providing the specific lower enclosure required for the 4-button NPA.

Correct identification, safe isolation, careful installation and complete functional testing are essential to achieving a reliable repair.
