Fault and Alarm Descriptions
Fault Type Displayed Text Description Default Setting
Overload Fault OVERLOAD
FAULT
Selectable Class 5-30, and S. Trips if the current integrator exceeds the
trip point.
Class 5
Over Current Fault OVERCURR
FAULT
Trips if the measured current is greater than the trip point setting for a
time that exceeds the over current trip time setting.
On, 110%, 30 s
Over Power Fault or
Alarm
OVERPOWER
FAULT
Trips if the measured kW is greater than the kW trip point setting
continuously for a time that exceeds the over power trip time setting.
On, 125%, 10 s
Under Power Fault or
Alarm
UNDER-POWER
FAULT
Trips if the measured kW is less than the kW trip point setting
continuously for a time that exceeds the under power trip time setting.
On, 65%, 1 s
Insulation Check Fault
and
Alarm
INSULATION
FAULT
Trips if the measured resistance of the motor windings is less than
insulation check resistance fault/alarm trip threshold.
Off, 500 kΩ (Alarm),
200 kΩ (Fault)
Over Voltage Fault or
Alarm
OVERVOLT
FAULT
Trips if the average of the 3 line-to-line voltages exceeds the nominal
voltage setting by the over voltage percentage setting continuously for a
time exceeding the over voltage trip time setting.
On, 110%, 10 s
Under Voltage Fault or
Alarm
UNDERVOLT
FAULT
Trips if the average of the 3 line-to-line voltages is lower than the nominal
voltage setting by the under voltage percentage continuously for a time
exceeding the under voltage trip time setting.
On, 90%, 10 s
Current Phase
Unbalanced
Fault or
Alarm
CURR UNBL
FAULT
Trips if any of the 3 measured phase currents deviates from the average
current by a value greater than or equal to the trip percentage setting.
On, 5%, 10 s
Voltage Phase
Loss
Fault VOLT LOSS
FAULT
Trips if the L-G voltage of any phase is more than 40% lower than the
average voltage.
On, 60 VAC, N/A
Voltage Phase
Unbalanced
Fault or
Alarm
VOLT UNBL
FAULT
Trips if any of the 3 measured line-to-line voltages deviates from the
average line-to-line voltage by a value greater than or equal to the
voltage phase unbalance trip percentage setting for a time exceeding the
voltage phase unbalanced trip time setting.
Off, 1%, 10 s
Cycle Fault Fault CYCLE FAULT Trips if run command is triggered at a rate exceeding the start limit
divided by the limit period.
Off
Locked Rotor Fault LCKD ROTOR
FAULT
Trips if the current exceeds 300% of the calculated FLA setting for 0.5
seconds, the current is flat or increasing and the power factor is not
changing. This protection is active during the first ten seconds of
operation after a start.
On
Stall Fault STALL FAULT Trips if the current exceeds 300% of the FLA for 0.5 seconds, the current is
flat or increasing and the power factor is not changing. This protection is
active after the first ten seconds of a start event and after the FLA has
been determined.
Off
Max Time to
Start
Fault START TIME
FAULT
Trips ten seconds after current is detected following a contactor closure, if
the average current is above 200% of the FLA setting and still declining.
Off
Out of
Calibration
Fault OUT OF CAL
FAULT
Trips if the measured peak inrush is outside the range of 400% to 1400%
of the FLA/SFA setting. This protection is only active during each start
sequence and for 10 seconds after every start.
Off
PT100/PT1000
Over Temp
Fault RTD TEMP FAULT Trips if the temperature measured by a PT100 or PT1000 exceeds the trip
temperature setting.
Off
Reverse Phase Fault PHASE ORDR
FAULT
Trips if the phase order detected is different than phase order setting of
either A-B-C or
A-C-B.
On
No Current Fault or
Alarm
NO CURR FAULT Faults if there is no current for three seconds after a start. Off
Unexpected
Current Flow
Alarm UNEXP CURR
FAULT
Alarms if the starter detects current flow above a threshold of 0.2 A while
the starter is in the stopped state.
Off
Ground Fault Fault GROUND FAULT Trips if the vector sum of the 3 measured phase currents exceeds the
ground fault threshold setting.
On, 1 A
