LED Color Status Description; cause Remedy
PWR - Off 24 V power supply has failed or is too low
(< 14 V) or internal fuse defective.
Check input voltage.
If input voltage is > 18 V and LED off:
Return component for repair.
Red Continuous
light
24 V power supply is available (>14 V);
internal board voltage fault.
Check input voltage.
If input voltage is > 18 V and LED red:
Return component for repair.
Green Continuous
light
24 V power supply OK.
Internal board voltages OK.
