Product Usage Instructions
- Mounting: Fix the panel to a secure bulkhead using the provided mounting brackets, ensuring the unit is leveled for proper viewing of the interface.
- Wiring: Route power and signal cables through certified explosion-proof glands to maintain the panel’s safety rating.
- Operational Mode: Toggle the local/remote switch to “Local” for manual control of lights, or “Remote” to integrate the panel with the platform’s central control system.
- Testing: Use the “Lamp Test” button to perform a diagnostic check on all indicators and light strings to ensure system integrity before flight operations.
Product Description
The TEF 4708 acts as the primary interface between the helideck lighting hardware and the platform’s power infrastructure. It includes intuitive visual indicators and switchgear, allowing deck crews to quickly switch on specific lighting sequences required for helicopter approach and landing. Its modular architecture allows for easy maintenance, while its heavy-duty construction ensures resilience against salt-mist, extreme weather, and vibration.

Frequently Asked Questions
- What is the significance of the “Local/Remote” switch? The “Local” setting gives control to the panel operators on the deck, while “Remote” allows the platform’s Bridge or Control Room to manage the lighting sequences.
- Is the TEF 4708 field-repairable? Component-level repairs (such as replacing switches or indicator lights) are possible, but the internal PLC logic and certified housing should only be serviced by certified technicians.
- How do I troubleshoot a system alarm? A flashing alarm LED typically indicates a loss of signal to one of the light strings; verify the continuity of the field cables connected to the output terminals.
- Can this panel be used in extreme cold? Yes, the standard design is rated for temperatures down to -40°C, making it suitable for Arctic offshore operations.
