FAQ

What should I do if the indicator lights are faulty?
 Check the wires to the door controls for any signs of burns.

Check if there is voltage across the pilot lamp terminals.
o
If there is no supply, disconnect the gray plug on J10 of the Group 5 PC
board and
reconnect it again to ensure proper fitting.
o If there is voltage across the pilot lamp terminals, order a replacement door mounted control.
If there is none, check the control panel for possible errors.
 Check if the voltage reading on the Group 5 control panel is correct.
o Check the readings with the voltage rating of the ATS.
o If there’s none, check the voltage across the lugs. If the correct voltage is supplied, check
the harness. If it is not the harness then the problem is on the controller.
