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 290E/291E Faults
Bulletin 290E/291E 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.
Flashing Yellow Transmit or receive activity present at 10 Mbps. No action
I/O Status Indicators
Off The user has plugged into the I/O, but the indicator did not
illuminate, once initiated. Verify the wiring of Input or Output is correct. When used
as an output point, ensure the corresponding bit in
parameter 49 [IOPointConfiguration] is set to Output.

Trip Status Description Action
1 Yes No On Overload Trip The load has drawn excessive current and
based on the trip class selected, the device
has tripped. Verify that the load is operating correctly and is
properly set-up, [FLASetting] Parameter 28,
[OLResetLevel] Parameter 29. The fault may be reset
only after the motor has sufficiently cooled.
2 Yes Yes Off Phase Loss Trip The ArmorStart LT has detected a missing
phase. This fault is generated by monitoring the relative
levels of the 3-phase currents. Correct phase
imbalance or disable fault using [ProtectFltEnable]
Parameter 42.
3 Yes No On Under Power Trip The ArmorStart LT detected switched or
unswitched power dip below 19.2 V for
greater than 50 ms, or 13 V for greater
than 4 ms. Check control voltage, wiring, and proper polarity (A1/
A2/A3 terminal).
4 No No On Sensor Short Trip This error indicates a shorted sensor,
shorted input device, wiring input
mistakes. Correct, isolated or remove wiring error prior to
restarting the system.
5 Yes Yes Off Phase Imbalance Trip The ArmorStart LT has detected a current
imbalance in one of the phases. Check the power system for current imbalance and
correct. Correct phase imbalance or disable fault using
[ProtectFltEnable] Parameter 42.
6 No No On Non-Volatile Memory
Trip This is a major fault, which renders the
ArmorStart LT inoperable. Possible causes
of this fault are transients induced during
Non-Volatile Storage (NVS) routines. 1. If the fault was initiated by a transient, power
cycling may clear the problem.
2. This fault may be reset by a [SetToDefaults]
Parameter 68.
3. Replacement of the ArmorStart LT may be required.
