PHASE S/C TRIP
Short Circuit Trip Level exceeded
for a time greater than the Short
Circuit Time Delay.
Check for motor winding shorts.

3
RAPID TRIP
Rapid trip / Mech. Jam Trip Level
exceeded for a time greater than
the Rapid Trip Time Delay.
Check system for jams /
excessive load.

4
SINGLE PHASE TRIP
Unbalance of over 30% present
for a time greater than 4 seconds.
Check continuity of incoming
three phase supply.

5
G/F TRIP
Ground Fault Trip Level exceeded
for a time greater than the
Ground Fault Trip Time Delay.
Check for motor winding to case
or ground shorts. Check motor for
moisture or conductive particles.

OVERLOAD TRIP
LOCKOUT TIME = XXX MIN.
Motor thermal capacity exceeded.
Motor lock-out time is also shown.
Excessive load with motor
running or locked rotor on start.
Wait for motor to cool.

7
START INHIBITED
LOCKOUT TIME = XXX MIN
Insufficient thermal capacity
available for motor to start (i.e.
capacity remaining is less than
Learned Start Capacity).
Wait for motor to cool.

8
U/B TRIP
Unbalance Trip Level exceeded
for a time greater than the
Unbalance Trip Time Delay (all
phases > 0.1 XFLC).
Check incoming supply phases
for unbalance. Check for motor
winding shorts. Increase Trip
Level if required.

STATOR RTD TRIP
RTD # X = XXX C
Stator RTD Trip Level
temperature exceeded on at least
one stator RTD.
Check motor ventilation and
ambient temperature. Allow motor
to cool.
