photocell and try again.
- Verify that there is an emitter and a receiver (E mark and R mark on the capsules) connected
to the correct cable (emitter to the yellow cable and receiver to the green one).
- Remove the photocell wiring from any place where there are “electric noises” such as motors,
supplies wiring,...being sure that the cables are not short-circuited.
- If you can use a console, please check the stability of the signal.
- Do not extend the photocell wires.
- Take in mind that in master mode the system recognizes automatically the photocell detector
after making a complete autoadjustment with the beam free controlled by the input signals.
• The door doesn’t answer to the test or auto-adjustment buttons.
