STARTS/HOUR TRIP
LOCKOUT TIME = XXX MIN.
Total number of motor starts over
the past hour greater than
Number of Starts / Hour setpoint.
Reduce number of starts during
normal motor operation.
12
ACCEL. TIME TRIP
Motor did not enter a normal
running state (i.e. phase current <
FLC) within Acceleration Time
setpoint.
Excessive load or locked rotor on
start.
13
PHASE REVERSAL TRIP
Phases not connected to motor
in proper sequence.
Check incoming phase
sequence and CT polarity.
14
SPEED SWITCH TRIP
Non-closure of speed switch
contacts within Speed Switch
Time Delay.
Locked rotor on start.
15
DIFFERENTIAL INPUT TRIP
Closure of differential relay
contacts.
Differential relay trip.
16
SPARE INPUT TRIP
Spare Input contact closure.
Check device connected to
Spare Input terminals.
17
OVERLOAD WARNING
TIME TO TRIP = XXXXX
Phase current greater than
Immediate O/L Level setpoint.
Reduce motor load.
18
G/F ALARMS
G/F = XX.X AMPS
Ground Fault Alarm Level
exceeded for a time greater than
the Ground Fault Time Delay.
Check motor windings for shorts,
moisture, or conductive particles.
19
U/B ALARM
U/B = XX PERCENT
Unbalance Alarm Level
exceeded for a time greater than
the Unbalance Time Delay.
Check incoming phases for
unbalance.
20
U/C ALARM
I(3 ph avg) = XXXX A RMS
Phase current less than
Undercurrent Alarm Level for a
time greater than the
Undercurrent Time Delay.
Check system for loss of load.
21
STATOR RTD ALARM
RTD # X = XXX C
Stator RTD Alarm Level
temperature exceeded on at
least one stator RTD.
Check motor ventilation and
ambient temperature.
22
RTD ALARM
RTD # XX = XXX C
RTD Alarm Level temperature
exceeded.
23
BROKEN RTD LINE
see RTD ACTUAL VALUES
Open circuit on RTD.
Check continuity of RTDs.
24
SPARE INPUT ALARM
Spare Input contact closure.
Check device connected to
Spare Input terminals.
25
SLAVE NUMBER XXX
NOT CONNECTED
Indicated relay SLAVE number is
not connected or not responding.
Check indicated relay SLAVE.
Check communication link wiring
