•
Clearly mark the new
wiring and update the
drawings for future
reference.
•
Check motor for
correct direction of
rotation at the moment
of starting.
T BYPASS
TRIP BYPASS
The MP-3000 tripped, yet
continued to see current
flowing to the motor for
more than a second after
the trip.
•
The contactor or
breaker is stuck or
jammed.
•
Or, someone has
bypassed the trip contact
so that the contactor
remained energized
after the trip.
•
Immediately open
upstream source breaker
or loadbreak switch.
Lock out this switch and
diagnose problem or find
bypass in starter.
INCOM
INCOM REMOTE TRIP
A remote PowerNet or other
data communications host
requested a motor trip.
Determine the cause of
the remote trip.

TRIP (log display only)
Too many starts were
performed in the user-set
period of time.
Wait for the oldest start
to clear from the stack.
Observe countdown on
display. See setpoints
P5L1 and P5L2.

ACTIVE SHOWN
Restarting blocked until
user-set time between starts
has expired.
Wait the indicated time
before restarting.
Note: The number of
cold starts (NOCS)
setpoint may suppress
this blocking during the
first n cold starts.

TRANSITION ERROR
TRIP
Starting current was still
above the transition
threshold P5L5 when the
transition timer P5L6 delay
expired.
•
This trip is initiated
only if setpoint P5L7 is
set to TRN I or TRN
T/C. Check the
correctness of transition
settings.
•
Check motor and load
for a cause of slower
than expected
acceleration.
