The troubleshooting LEDs are located on the receiver board. Use the following table to identify faults and
corrective action.
In order to reach the signaling, the receiver must be accessible, connected, and the screws located on the
receiver lid must be unscrewed using the proper screw driver whenever the LEDs are not externally
visible.
The LEDs on the receiver board are POWER, HARDOK, SIGNAL, DATA, ID, ORDER and RELAY.
