PR 0.3 Effective 8/99
NOTE
If the MP-3000 is in Program mode with the motor running and a trip condition occurs, the relay
exits the Program mode without saving any setpoint changes which might have been entered in
the scratchpad area up to that time. After diagnosing the trip, begin the reprogramming job over
again. Note that the relay was protecting the motor with only its old setpoints at the time of the
trip.
12.3 Troubleshooting the MP-3000 —
Troubleshooting the MP-3000 is straightforward. If the
Operator Panel is inoperative (either the LEDs and the Display Window are off or they are not
responding properly), check Table 12.3. When doing so, keep in mind that the most likely and
easy to check problems are listed first.
WARNING
If the MP-3000 is replaced, the user MUST reprogram all setpoint values for the specific
application in the new unit.
Do not
attempt to restart the motor until all values are entered and
checked. Damage to equipment and/or personnel injury may occur if this procedure is not
followed.
The MP-3000 performs continuous internal diagnostic checks. If a malfunction is detected
during a diagnostic check, one of the messages listed in Table 12.4 is displayed. The user
setpoint P12L16 determines whether the relay just alarms for these problems, or alarms and trips
the motor.
WARNING
Users with critical processes may choose to alarm only, but it is essential to replace the relay as
soon as possible. Assume that the relay is not protecting the motor if one of these alarms occur.
Manually monitor the motor and process closely. Do not rely on MP-3000 displays in this case.
If the motor trips or alarms for one of these failures, the MP-3000 must be replaced. Return to
the factory for repair. There are no user service procedures.
