Jam Trip
During normal running (after starting
period), the RMS current draw exceeds the
prescribed fault level. This fault is generated
when current is greater than the Jam Trip
Level for longer than the Jam Delay time
after the Jam Inhibit time has expired.
1. Check for the source of the jam (for example,
excessive load or mechanical transmission
component failure).
2. Check [JamInhibitTime] Parameter 70,
[JamTripDelay] Parameter 71, and [JamTripLevel]
Parameter 72 setting.

Yes
Off
Stall Trip
During starting, the motor did not reach
running speed within the prescribed
period. This fault is generated when the
RMS current is greater than
[StallTripLevel] Parameter 75 or longer
than [StallEnbldTime] Parameter 74
during motor starting.
1. Check for source of stall (for example, excessive
load, or mechanical transmission component
failure).
2. Check [StallEnabledTime] Parameter 74 and
[StallTripLevel] Parameter 75.
3. Check if [FLASetting] Parameter 28 is set correctly.

No
Yes
Off
Underload Trip
Underload protection is for undercurrent
monitoring. A trip occurs when the motor
current drops below the trip level.
Check motor and mechanical system for broken shaft,
belts, or gear box. Check [ULInhibitTime] Parameter
76, [ULTripDelay] Parameter 77, [ULTripLevel]
Parameter 78, and [ULWarningLevel] Parameter 79.

Output Short Trip
This fault is generated when a hardware
output short circuit condition is detected.
Correct, isolate or remove wiring error prior to
restarting the system.

User Defined Trip
This fault is generated either in response
to the rising edge of user input 0...5,
[Input00Function...Input- 05Function]
Parameter 58...63, or by DeviceLogix.
This fault is generated based on user configuration.
This fault may be reset after the condition that caused
it is removed. For example, the Auxiliary Input goes
low or the DeviceLogix logic drives the bit low.

Hardware Fault Trip
This fault indicates that a serious
hardware problem exists.
Power cycle to correct. If fault persists the ArmorStart
LT requires replacement.
