Door Interrupt System with FYQLA1-140R-3 Logic Amplifier

Fault diagnosis

If fault LED flashes and no sensor alignment problem can be found:
• Turn off power
• Unwire sensors from input terminals
• Power up unit
•
If fault LED begins to flash repeatedly after 2-3 seconds, the system needs to be
replaced. If the fault LEDs do not begin to flash:
• Remove power, then wire one sensor (R,W,B,O) connection at a time. Apply
power, waiting 2-3 seconds. Repeat sequence with all sensors until fault
LED begins to flash. This will be the sensor/actuator that is generating
the fault condition. Reevaluate alignment and terminal connections. If no
problem is found, replace the sensor and/or actuator in question
