Quick Reference
Troubleshooting
The LEDs on the front of the ArmorStart LT provide an indication as to the
health of the device and network. The following is a brief troubleshooting guide.
Fault LED Indications
The RUN/FLT LED will blink red in a prescribed fault pattern when a
protection fault (trip) condition is present. The LED will blink in 0.5 second
intervals when indicating a fault code. Once the pattern is finished, there will be a
2 second pause after which the pattern will be repeated.
Bulletin 290D/291D Faults
Bulletin 290D/291D faults are detected by the main control board. When the
[ProtFltResetMode] Parameter 41 is set to the value 1=Automatic, the auto
resettable faults in the table will reset automatically when the fault condition is
no longer present.
