Inputs
The INPUTS LEDs are indicators for system inputs. FTR1 represents the Mute masking input.
Relays
Relay RL1 LED indicates a general fault. When the LED is on, no fault exists and Relay RL1 is
energized. When the LED is off, a fault has occurred and Relay RL1 is de-energized. AUX LED is
for future use.
Protocessor
The Protocessor LEDs indicate the state of the Protocessor.
The ERR LED will go on solid 15 seconds after power up. It will turn off after 5 seconds. A steady red light
will indicate there is a system error on the unit. The RUN LED will start flashing 20 seconds after power
indicating normal operation. The SPL LED will be off for normal operation.
