Possible Causes
Faulty safety beam self‑test, Incorrect wiring on safety terminals, Shorted accessory on safety circuit, Defective control PCB safety relay
How to Fix / Troubleshooting
Safety first: Do not bypass safety circuits for normal operation. Disconnect power before rewiring.
Steps:
- Disconnect accessories: Remove any non‑Henderson accessories (keypads, add‑on receivers) from the safety and control terminals.
- Verify wiring: Compare all low‑voltage connections to the Henderson wiring diagram. Correct any miswired or doubled‑up connections on the safety beam terminals.
- Test with only beams: Reconnect only the Henderson safety photocells and wall control. Power up and see if E15 clears.
- Board safety relay: If E15 persists with correct wiring and known‑good beams, the internal safety relay on the Henderson control PCB may have failed. Replace the board.
