Description
TER Industrial Signal Lights
TER Industrial Signal Lights provide a robust visual and audible signalling solution for cranes and demanding industrial machinery where clear, long-distance indication is required. Specifically developed for tower cranes and harbour cranes, the system combines high-performance LED signal beacons with an optional wall-mounted siren to provide operators, ground personnel and surrounding workers with highly visible machine status and warning information.
Industrial lifting and material handling environments require signalling equipment that remains clearly visible under challenging operating conditions. Crane structures can extend over substantial distances, equipment may operate outdoors, and visual signals may need to be recognised quickly by personnel working at different positions around a site. TER Industrial Signal Lights have been designed around these requirements, combining powerful LED illumination, durable construction and flexible signalling modes within a configurable industrial assembly.
The system can incorporate between two and four Universal Signal Beacons mounted on an aluminium plate. Different light colours and operating modes can be used to communicate machine status, movement conditions, warnings or other information determined by the control-system design. A wall-mounted siren can also be incorporated where an audible warning is required in addition to visual indication.
This combination provides a practical signalling system for applications including tower cranes, harbour cranes, overhead travelling cranes and gantry cranes. TER also identifies automatic car washes and railway signalling among the applications for the Industrial Signal Light system.
Industrial Signalling Designed for Tower and Harbour Cranes
TER has specifically developed its Industrial Signal Lights for tower and harbour crane applications. These machines present particular challenges for visual signalling because of their physical size, operating height and the distances that can exist between the signal device and the people who need to recognise its status.
A tower crane, for example, can operate high above the surrounding work area. Visual indication therefore needs to provide strong visibility rather than simply illuminating a small area immediately around the device. Harbour cranes can present similar challenges, with large machinery operating across substantial industrial areas and exposed outdoor environments.
TER addresses this requirement through the use of high-performance LED beacon technology designed to provide excellent long-distance visibility. The signal lights can therefore provide a clearly identifiable visual indication as part of the wider machine control and warning system.
The system is not limited to one fixed configuration. Depending on the requirements of the machinery, it can be configured with two, three or four signal beacons, allowing the signalling arrangement to be adapted to the information that needs to be communicated.
Two to Four Universal Signal Beacons
The modular arrangement of the TER Industrial Signal Light allows the assembly to incorporate between two and four Universal Signal Beacons. This provides flexibility when designing the signalling system for a particular crane or industrial machine.
A simpler installation may require only two visual states, while more complex machinery may benefit from three or four separate colours to communicate different operating conditions. The appropriate configuration can be selected according to the machine control architecture, site procedures and required signalling logic.
For example, different colours may be assigned to normal operation, machine movement, warning conditions or another status determined by the equipment designer. The exact meaning of each colour should be established by the machine or site control philosophy and communicated clearly to personnel.
The ability to incorporate multiple beacons within one organised assembly can also simplify installation compared with mounting several unrelated signalling devices separately around the machinery.
High-Performance Power LED Technology
At the heart of the TER Industrial Signal Light is high-performance LED technology designed for reliable industrial signalling. TER specifies a 5 × 3 W Power LED module for the beacons used within the assembly.
Power LED technology is particularly well suited to applications requiring visibility over greater distances. TER explains that its Power LED beacon designs provide light suited to longer-distance viewing through their angular light characteristics, making this technology a logical choice for large crane installations.
Compared with traditional incandescent signalling technology, LED systems can provide long operating life while reducing the need for frequent lamp replacement. This can be especially valuable on crane structures, where accessing signalling equipment for maintenance may require additional planning or machinery downtime.
TER specifies an LED life duration of approximately 50,000 hours. This long nominal service life supports the use of the Industrial Signal Lights in applications where dependable signalling is required over extended operating periods.
Actual service life will depend on factors such as operating conditions, supply quality, switching frequency, environmental exposure and installation, but the specified LED lifetime demonstrates the product’s suitability for long-term industrial service.
Excellent Long-Distance Visibility
Visibility is one of the most important considerations when selecting a signal light for crane applications. A visual indicator provides little value if personnel cannot clearly recognise it from their normal working position.
TER has designed the Industrial Signal Light specifically to provide excellent long-distance visibility. This is particularly important on tower and harbour cranes, where the distance between the signal assembly and the observer may be significantly greater than in a conventional machine-control application.
The combination of 90 mm lenses and Power LED modules provides a strong visual signal intended for demanding industrial environments. Multiple colours can be arranged on the same mounting plate, making it possible to distinguish different machine states visually.
This can assist with rapid recognition of machinery conditions, particularly when a signalling system is designed so that each colour and operating pattern has a clearly defined meaning.
White, Red, Yellow and Green Signal Colours
The TER Industrial Signal Light is available with white, red, yellow and green light colours. These options provide flexibility when establishing a visual signalling hierarchy for industrial machinery.
Red may be used within a machine control philosophy to identify a warning or stop-related condition, while green may indicate another operational state. Yellow can provide a distinct warning or attention signal, and white can be used for an additional machine condition or general indication.
The meaning assigned to each colour depends on the control system and applicable machinery or site requirements. The important advantage is that the TER system provides multiple clearly distinguishable colours that can be incorporated into one organised industrial signalling assembly.
When several colours are used together, operators and personnel can identify machine conditions without relying solely on text displays or other control interfaces. This can be particularly useful where information needs to be communicated across substantial distances.
Multiple Light Operating Modes
Colour is not the only way in which the TER Industrial Signal Lights can communicate information. The beacons also provide several operating modes, allowing different visual patterns to be used to distinguish machine states.
TER specifies steady, flashing, strobing and rotary light modes. These different signalling behaviours give system designers additional flexibility when configuring visual warnings and operating indications.
A steady light can provide continuous status indication, while flashing or strobing operation can attract greater attention where a change of condition needs to be recognised. Rotary operation provides another distinctive visual pattern that can be assigned according to the requirements of the application.
The ability to use different operating modes means a signalling system can communicate information through both colour and light behaviour. This can make different machine states easier to distinguish, particularly in complex industrial environments.
Selectable Light Modes for Flexible Machine Signalling
TER also provides the possibility of changing the light mode using a specific button on the switch board. This allows the signalling behaviour to be configured according to the required machine application.
This flexibility can be valuable when equipment requirements change or where a particular operating mode is preferred for a specific installation. Instead of requiring completely different signal devices for different visual effects, the available modes provide multiple signalling possibilities within the same product architecture.
Configuration should always be established as part of the overall machine control design so that each signal remains clear and unambiguous to operators and surrounding personnel.
90 mm Polycarbonate Signal Lenses
The TER Industrial Signal Lights use 90 mm diameter polycarbonate lenses. Polycarbonate is well suited to industrial signalling applications because it combines good optical properties with mechanical durability.
In crane environments, signal devices may be exposed to vibration, airborne contamination and general industrial conditions. Durable lens materials help protect the internal LED components while allowing the light output to remain clearly visible.
The 90 mm lens diameter also provides a substantial visual surface for the signal, supporting the long-distance visibility required for large machinery applications.
Durable ABS Beacon Housing
The individual signal beacons use an ABS housing designed to provide durable protection for the internal electronic and lighting components.
TER specifies that the materials and components used within the Industrial Signal Light are wear resistant and provide protection against water and dust. This is important for equipment intended for use around heavy industrial machinery, particularly where the installation is exposed to changing environmental conditions.
The combination of polycarbonate lenses and ABS housings provides a lightweight but durable beacon construction suitable for mounting as part of the complete industrial signal assembly.
Aluminium Mounting Plate
The Universal Signal Beacons are installed on an aluminium plate to form the complete TER Industrial Signal Light assembly. This provides a structured mounting arrangement for the individual visual indicators and optional audible signalling equipment.
Using a common mounting plate keeps the signal devices together in a clear and organised configuration. This can assist installation while also making the visual sequence easier to understand from a distance.
TER provides a high degree of customisation for both the plate and the overall configuration. This allows the signalling assembly to be adapted to the requirements of different crane and industrial machinery installations.
IP65 Protection for Industrial Environments
Industrial signalling equipment must continue to function when exposed to the environmental conditions surrounding the machinery. TER classifies the Industrial Signal Light as IP65.
This provides a high level of protection against dust ingress and water exposure, supporting installation in demanding industrial environments where signalling equipment may encounter airborne contaminants, moisture and outdoor conditions.
IP65 protection is particularly relevant for tower and harbour cranes, where the signalling assembly may be installed externally and exposed to changing weather conditions throughout its service life.
Maintaining the specified level of protection depends on correct installation, including appropriate electrical connections and proper assembly of the associated components.
Operating Temperature from -20°C to +50°C
The TER Industrial Signal Light is designed to operate across an ambient temperature range from -20°C to +50°C. This broad operational range supports use in outdoor and industrial environments subject to significant temperature variation.
Crane equipment may operate throughout changing seasons and in locations where machinery is exposed directly to environmental conditions. Components installed on these machines therefore need to tolerate a wider range of temperatures than equipment located inside a controlled electrical room.
The combination of temperature resistance, IP65 protection and durable construction makes the TER Industrial Signal Light well suited to demanding crane and industrial signalling applications.
Visual and Audible Warning in a Single System
While visual indication is the primary function of the Industrial Signal Light assembly, TER also provides the option of incorporating a wall-mounted siren. This allows visual and audible warnings to be combined within a coordinated signalling system.
Audible indication can be particularly useful where personnel may not always have a direct line of sight to the signal lights or where a machine condition requires additional attention.
The siren can be supplied with continuous or intermittent sound operation, and TER also allows the Industrial Signal Light to be configured without a siren where only visual signalling is required.
This modular approach means the system can be adapted to the needs of the particular machine rather than requiring every installation to use an identical signalling arrangement.
Industrial Signal Lights for Crane Safety and Machine Status Indication
Effective industrial signalling contributes to clearer communication between machinery and the people working around it. On large lifting equipment, this communication can be particularly important because machine movements and operating conditions may affect personnel across a substantial working area.
TER Industrial Signal Lights provide a highly visible platform for communicating these conditions. Multiple beacon colours, selectable light modes and optional audible signalling can be combined to create a signalling arrangement appropriate to the machinery and operating environment.
With durable construction, long-life Power LEDs, IP65 environmental protection and configurable beacon arrangements, the system provides a purpose-designed signalling solution for tower cranes, harbour cranes and other demanding industrial applications.
Optional Wall-Mounted Siren for Audible Warning
The TER Industrial Signal Lights can be combined with an optional wall-mounted siren to provide audible warning in addition to the visual indication produced by the LED signal beacons. This creates a coordinated signalling system capable of communicating machine status through both light and sound.
Audible signalling can be particularly valuable around cranes and large industrial machinery because personnel may not always have a clear line of sight to the visual signal assembly. Machinery structures, equipment, buildings or other obstacles can restrict visibility, while workers may also be concentrating on tasks that prevent continuous observation of the signal lights.
By incorporating an audible warning, the signalling system can attract attention before personnel visually identify the corresponding beacon condition. The exact function of the siren should be determined by the machine control philosophy and the requirements of the installation.
TER allows the Industrial Signal Light system to be supplied with or without the siren, providing flexibility for applications where visual indication alone is sufficient or where combined visual and audible signalling is preferred.
Continuous and Intermittent Audible Signals
The optional siren provides different audible signalling possibilities. TER specifies continuous and intermittent operating modes, allowing the sound pattern to be selected according to the required warning function.
Different audible patterns can help personnel distinguish between operating states, particularly when the siren is used alongside different beacon colours and visual modes. A continuous tone may be assigned to one machine condition while an intermittent warning can be used for another, depending on the control-system design.
The meaning of each audible pattern should remain consistent throughout the installation so that personnel can quickly recognise and respond to the warning being communicated.
Powerful Audible Warning for Industrial Environments
Industrial workplaces can contain significant background noise generated by motors, drives, lifting machinery, production equipment, vehicles and other operating systems. An audible warning device therefore needs sufficient sound output to attract attention within the intended working environment.
TER specifies sound output for the optional siren of up to approximately 121 dB at 10 cm and approximately 100 dB at 100 cm, depending on the applicable configuration and measurement conditions.
These sound levels provide a strong audible warning suitable for demanding machinery applications. However, appropriate siren selection and positioning should consider the actual site environment, ambient noise level, distance from personnel and applicable occupational noise requirements.
Sound output should be sufficient to communicate the required warning without creating unnecessary or inappropriate noise exposure. The overall warning system should therefore be considered as part of the machinery and workplace risk assessment.
Flexible AC and DC Supply Options
Industrial machinery can use a variety of control voltages, particularly across crane, material handling and automation applications. TER therefore provides the Industrial Signal Lights with different AC and DC supply options according to the selected configuration.
This flexibility allows the signalling assembly to be integrated into a wide range of existing and newly designed control systems. Low-voltage configurations can be selected for machinery using corresponding control supplies, while other configurations accommodate higher industrial control voltages.
The correct supply voltage should always be confirmed from the TER technical data for the specific product configuration before connection. Applying an incorrect voltage can damage signalling components and may compromise reliable operation.
System designers should also consider supply stability, protection devices, cable sizing and switching arrangements when integrating the signal lights into the machine electrical system.
M12 Electrical Connections for Efficient Integration
TER uses M12 electrical connections within the Industrial Signal Light system, providing a practical connection method commonly used throughout industrial machinery and automation applications.
M12 connectors provide a compact and organised interface that can simplify installation and maintenance compared with individually terminating multiple signal wires directly inside each beacon housing.
TER specifies a 5-pin M12 connector for the two-light configuration and an 8-pin M12 connector for the four-light configuration. The selected connection arrangement corresponds with the number of signalling elements incorporated into the assembly.
Correct mating connectors, cable assemblies and wiring should be selected according to the electrical requirements of the installation. Connections should also be installed in a manner that maintains the environmental protection required by the application.
Two-Light Industrial Signal Configuration
A two-light configuration provides a compact signalling solution for machinery where two primary visual states need to be communicated. This can be useful for relatively straightforward operating logic where the control system only requires two clearly distinguishable visual indications.
The two beacons can be configured using appropriate available colours and operating modes to provide the required visual distinction. For example, one light may communicate a normal operating state while another identifies a warning or machine condition, depending on the application.
TER specifies a 5-pin M12 connection for the two-light version, helping provide an organised electrical interface for the complete assembly.
Where more signalling states are required, additional beacon configurations can be selected rather than attempting to communicate excessive information through only two visual indicators.
Three and Four-Light Signal Arrangements
More complex machinery may require additional visual information. The TER Industrial Signal Light can therefore be configured with up to four Universal Signal Beacons, allowing multiple operating conditions to be represented within one assembly.
A four-light system can combine available white, red, yellow and green signals to provide clearly differentiated visual states. These colours can also be combined with steady, flashing, strobing or rotary operating modes where appropriate.
The additional signalling capacity is particularly useful on larger crane systems or industrial machines where personnel need to distinguish between several machine conditions from a distance.
TER specifies an 8-pin M12 connection for the four-light arrangement. As with all configurations, the exact wiring and electrical characteristics should be confirmed against the documentation supplied for the selected assembly.
Customisable Industrial Signal Light Configuration
One of the significant advantages of the TER Industrial Signal Lights is the ability to customise the assembly according to the requirements of the application. Industrial machinery varies considerably in physical arrangement, control philosophy and signalling requirements, making a flexible product architecture particularly useful.
The number of beacons, colour combination, visual operating modes and optional audible warning can be selected to suit the required machine function. TER also provides customisation possibilities for the mounting plate and overall assembly.
This allows engineers and machinery manufacturers to specify a signalling solution appropriate to the equipment rather than adapting the machinery around a completely fixed signal product.
For replacement applications, configuration flexibility can also assist when matching the signalling requirements of existing machinery, subject to confirmation of dimensions, electrical characteristics and control-system compatibility.
Integration with Crane Control Systems
The TER Industrial Signal Lights can be incorporated into a wider crane control system to provide visible indication of selected operating conditions. The signal assembly does not determine the operating logic itself; instead, individual lights and audible warnings are activated according to signals generated by the associated control system.
Depending on the crane design, these commands may originate from contactors, relays, PLC outputs, variable-speed drive systems or other control equipment. The signalling system then converts those electrical commands into easily recognisable visual or audible information.
This arrangement provides considerable flexibility because the meaning of each beacon can be determined by the machinery designer. The same TER signal assembly can therefore support different applications by changing the control logic and selected beacon configuration.
Visual Indication for Crane Operating Conditions
Large crane systems may benefit from visual indication of several different operating conditions. Depending on the machine and site requirements, signals could be associated with machine availability, operating status, movement conditions, warnings or other control-system states.
The availability of multiple colours and visual operating modes allows these conditions to be communicated in a way that is easy to distinguish from a distance.
A flashing or strobing signal can provide greater visual emphasis than a steady indication, while different colours can separate one type of machine state from another. Where appropriate, the optional siren can add an audible warning to particularly important conditions.
The precise meaning of each indication should be established during system design and reflected in operating instructions and site procedures.
Industrial Signal Lights for Tower Cranes
Tower cranes are one of the primary applications identified by TER for the Industrial Signal Light system. Their height and physical scale create particular challenges for machine signalling, making long-distance visibility especially important.
Signals mounted on a tower crane may need to be recognised by personnel working at ground level or elsewhere around a construction site. The high-performance Power LED modules and substantial signal lenses provide the strong visual indication required for these types of applications.
Multiple beacon colours can communicate different operating states, while the optional audible warning can provide another means of attracting attention when required by the system design.
The durable construction, IP65 protection and operating temperature range also support installation on crane structures exposed to changing outdoor conditions.
Industrial Signal Lights for Harbour Cranes
Harbour cranes operate in another demanding environment where clear industrial signalling can be essential. Large machinery, significant operating distances and busy material handling areas can make rapid recognition of machine status particularly valuable.
The TER Industrial Signal Light provides a highly visible signalling platform that can be configured according to the requirements of harbour lifting equipment.
LED technology supports long-distance visibility and extended operating life, while the durable beacon housings and mounting assembly provide protection suitable for demanding industrial conditions.
Environmental suitability should nevertheless always be evaluated for the particular installation, especially where equipment may be exposed to aggressive coastal or marine conditions.
Overhead Travelling and Gantry Crane Applications
Although specifically developed for tower and harbour cranes, TER also identifies overhead travelling cranes and gantry cranes as suitable applications for the Industrial Signal Lights.
These machines frequently operate within factories, warehouses, production plants, ports and material handling facilities where personnel may be working in or around the crane operating area.
A clearly visible signal assembly can communicate selected crane conditions across the work area, providing information without requiring personnel to view the crane operator’s control station or another local display.
The configurable arrangement is useful because different facilities may require different signalling philosophies. Two lights may be sufficient for one application, while another installation may require three or four visual states together with an audible warning.
Applications Beyond Crane Systems
The capabilities of the TER Industrial Signal Lights are also relevant to applications beyond lifting machinery. TER identifies automatic car washes and railway signalling among the potential uses for the product.
These applications share a common requirement for clear and easily recognisable visual indication. Machinery status often needs to be communicated quickly to operators, users or surrounding personnel, sometimes from a considerable distance.
The combination of multiple colours, selectable operating modes and optional audible warning provides a versatile signalling platform that can be adapted to a variety of industrial automation systems.
Long-Life LED Technology Reduces Routine Lamp Replacement
Maintenance accessibility is an important consideration when installing signal lights on large machinery. A signalling device located high on a crane structure may be significantly more difficult to access than one installed at ground level.
The approximately 50,000-hour LED life specified by TER can help reduce the frequency of routine lamp replacement compared with traditional lighting technologies.
This can contribute to lower maintenance requirements over the operating life of the machinery, particularly where accessing the signalling assembly requires specialised equipment or planned downtime.
Periodic inspection remains important to identify physical damage, contamination, loose connections or other conditions that could affect signal visibility and operation.
Clear Signalling for Demanding Industrial Machinery
The TER Industrial Signal Lights combine high-performance visual signalling with flexible configuration options designed around the requirements of cranes and heavy industrial machinery.
Two to four Universal Signal Beacons can be combined with different colours and operating modes, while the optional siren provides an additional audible warning where required. M12 electrical connections support organised machine integration, and multiple supply options allow the assembly to accommodate different industrial control architectures.
For tower cranes, harbour cranes, overhead travelling cranes, gantry cranes and other industrial equipment, these characteristics provide a practical solution where machine status needs to remain clearly visible across substantial operating distances.
Combined with IP65 environmental protection, durable construction and long-life LED technology, the TER Industrial Signal Light provides a configurable signalling system engineered for demanding industrial service.
Installation and Positioning of Industrial Signal Lights
Correct positioning is an important consideration when installing TER Industrial Signal Lights on cranes and other large industrial machinery. The effectiveness of a visual signalling system depends not only on the performance of the signal beacons but also on whether the lights can be clearly seen from the locations where personnel are expected to observe them.
The assembly should therefore be positioned with consideration for viewing distance, machinery structure, surrounding equipment and potential obstructions. On tower cranes and harbour cranes, the physical scale of the equipment can make this particularly important.
The mounting arrangement should provide a secure installation while maintaining appropriate visibility of the individual signal lenses. The aluminium mounting plate provides a practical structure for installing the Universal Signal Beacons together as a coordinated assembly.
Where an optional audible warning device is installed, the location of the siren should also be considered in relation to surrounding personnel, background noise and the intended warning area.
Optimising Visibility on Large Crane Installations
Large cranes present different signalling requirements from smaller industrial machines. A signal light installed on a tower crane, for example, may need to remain identifiable from a considerable distance and from several viewing positions around the work area.
The 90 mm polycarbonate lenses and Power LED technology used by TER are designed to provide strong visual indication for these demanding applications. However, the final installation should also consider the orientation of the beacons and expected viewing angles.
Structures, platforms, machinery components or stored materials should not unnecessarily obstruct the signal assembly. Where personnel need to observe machine status from several areas, the signalling arrangement should be evaluated to ensure suitable visibility from the required positions.
Good positioning allows the performance of the TER signal beacons to be used effectively and helps provide clear communication of machine status throughout the intended operating area.
Combining Colour and Light Patterns for Clear Indication
The availability of white, red, yellow and green signal colours gives machinery designers a flexible visual language for communicating different machine conditions. This flexibility is further increased by the availability of steady, flashing, strobing and rotary operating modes.
Combining colour and operating pattern can make different machine states easier to distinguish. A continuous visual signal can be used for a persistent operating condition, while a flashing or strobing signal may be selected where greater attention is required.
However, signalling should remain simple and consistent. Using too many combinations without a clearly established meaning can make a warning system difficult to interpret. Each colour and light pattern should therefore have a defined function within the machine control philosophy.
Operators and other relevant personnel should understand the meaning of the signals used on the equipment so that the information can be recognised quickly and consistently.
Visual and Audible Signalling Working Together
Combining visual beacons with the optional siren can provide a more comprehensive signalling arrangement than either method alone. Visual indication communicates machine status clearly when personnel have line of sight to the assembly, while an audible warning can attract attention when personnel are looking elsewhere.
This can be particularly valuable in busy industrial environments where operators and ground personnel may be concentrating on different tasks. The audible warning can alert personnel to a condition, after which the colour or behaviour of the corresponding beacon can provide additional visual information.
The exact relationship between visual and audible signals should be established by the machinery designer. Not every visual indication necessarily requires an audible warning, and different applications may use the siren for specific machine states only.
Selecting the Correct TER Industrial Signal Light Configuration
The configurable nature of the TER Industrial Signal Light allows the product to be adapted to a wide range of machinery applications. Selecting the appropriate arrangement begins with determining how many distinct machine conditions need to be communicated.
A two-light assembly may provide sufficient indication for relatively simple equipment. More complex crane systems may benefit from three or four signal beacons, allowing additional operating conditions to be represented independently.
Colour selection should then be considered together with the required operating modes. White, red, yellow and green beacon options can be combined with steady, flashing, strobing or rotary light behaviour to create the required visual signalling arrangement.
Where audible warning is required, the optional siren and its operating characteristics should also be considered. Electrical supply, M12 connection requirements, mounting arrangement and the physical dimensions of the installation should form part of the final selection process.
Electrical Integration and Control Logic
The TER Industrial Signal Lights are intended to operate within a wider electrical control system. The individual signal beacons respond to electrical commands generated by the machinery control architecture.
Depending on the equipment, these commands may be provided through PLC outputs, relays, contactors or other industrial control devices. This allows the signal assembly to communicate conditions determined elsewhere within the machine system.
For example, a crane control system may activate a particular beacon when a defined machine state occurs. Another output may operate a different colour or activate the audible warning. The actual control logic remains application dependent.
Electrical integration should follow the ratings and connection information provided by TER for the selected configuration. Supply voltage, connector arrangement, switching devices, cable selection and circuit protection should all be considered during system design.
Maintenance and Routine Inspection
The long service life associated with LED technology can reduce routine lamp replacement requirements, but industrial signal equipment should still be inspected periodically to ensure reliable operation.
Visual inspection can identify damaged lenses, housing deterioration, contamination, loose mounting components or cable damage. Signal lenses should remain sufficiently clean for the required visual output to be recognised from the intended viewing positions.
Electrical connections should also remain secure and protected from environmental exposure. Where M12 connectors are used, the mating connection should be correctly assembled and maintained to support dependable electrical operation.
The optional siren should be tested periodically where it forms part of the machine warning system. Inspection and maintenance intervals should reflect the operating environment, frequency of machinery use and applicable site procedures.
Advantages of Long-Life LED Industrial Signalling
LED technology provides several advantages for industrial signalling, particularly where the equipment is installed in locations that are difficult to access. TER specifies an LED service life of approximately 50,000 hours for the Industrial Signal Lights.
Reducing the frequency of routine lamp replacement can be especially beneficial for tower cranes, harbour cranes and other large machinery. Maintenance work at height or on major crane structures may require access equipment, isolation procedures and planned downtime.
Long-life LED technology can therefore contribute to reduced routine maintenance requirements while also providing the high-performance illumination required for long-distance signalling.
Durability for Demanding Industrial Service
TER Industrial Signal Lights are designed around the environmental requirements of industrial machinery. The combination of polycarbonate lenses, ABS beacon housings, aluminium mounting plate and IP65 protection provides a durable signalling assembly suitable for challenging operating environments.
The specified ambient operating temperature range of -20°C to +50°C further supports applications where the equipment is exposed to changing environmental conditions.
These characteristics are particularly relevant for cranes installed outdoors, where signalling equipment may be subjected to weather, airborne contamination and substantial temperature variation throughout its service life.
Important Application Limitation – Not for Explosive Atmospheres
TER Industrial Signal Lights should not be confused with explosion-protected signalling equipment. TER specifically states that this product must not be used in environments with potentially explosive atmospheres.
This distinction is important when selecting signalling equipment for industrial applications. The rugged construction and IP65 environmental protection of the Industrial Signal Lights do not constitute ATEX or IECEx explosion protection.
If signalling equipment is required within a classified hazardous area, a product specifically designed and appropriately certified for that environment should be selected instead.
Before installation, the environmental classification of the intended location should therefore be confirmed as part of the equipment selection process.
Industrial Signal Lights for Tower Cranes
Tower cranes represent one of the key applications for the TER Industrial Signal Lights. The height and scale of these machines create a need for signalling that can remain clearly identifiable from substantial distances.
High-performance Power LED technology, multiple beacon colours and selectable light patterns allow the system to communicate different crane operating conditions visually. The optional audible warning can provide an additional method of attracting attention where required.
The configurable mounting arrangement also allows the number of lights and overall signal assembly to be selected according to the requirements of the crane installation.
Industrial Signal Lights for Harbour Cranes
Harbour cranes can also benefit from highly visible machine status indication. These large lifting systems frequently operate across extensive material handling areas where operators and surrounding personnel may be positioned significant distances from the machinery.
The TER system provides a configurable visual signalling platform for these applications, combining long-distance LED visibility with multiple signal colours and operating modes.
Where audible indication is required, the optional siren can complement the visual signals to create a coordinated warning arrangement.
Signalling for Overhead Travelling and Gantry Cranes
Overhead travelling cranes and gantry cranes are widely used throughout manufacturing facilities, warehouses, workshops, ports and material handling operations. Clear machine indication can provide useful information to personnel working within these environments.
TER Industrial Signal Lights can be integrated with the crane control system so that different operating states produce clearly identifiable visual signals.
The ability to configure two to four beacons makes the system suitable for both relatively simple crane installations and more complex control architectures requiring several distinct indications.
Flexible Signalling for Industrial Automation
Although crane applications are a major focus of the product, the underlying characteristics of the TER Industrial Signal Lights also make them relevant to other industrial automation systems.
Any application requiring highly visible machine status indication may benefit from multiple LED colours, selectable visual patterns and optional audible warning. TER identifies applications including automatic car washes and railway signalling in addition to crane systems.
The modular configuration allows the signalling system to be adapted to the required machine logic while the industrial construction supports operation in demanding environments.
Why Choose TER Industrial Signal Lights?
TER Industrial Signal Lights combine several important characteristics within one configurable industrial signalling system. High-performance Power LED technology provides excellent long-distance visibility, while multiple colours and selectable light modes allow different machine conditions to be communicated clearly.
The system can incorporate between two and four Universal Signal Beacons, allowing the visual configuration to match the requirements of the machinery. An optional wall-mounted siren provides audible warning where additional operator or personnel notification is required.
Other advantages include durable polycarbonate lenses, ABS beacon housings, an aluminium mounting arrangement, IP65 environmental protection, M12 electrical connections and an operating temperature range suitable for demanding industrial applications.
Together, these characteristics provide a versatile signalling solution particularly suited to large cranes and industrial machinery where visibility, durability and configuration flexibility are important.
