The trip data actual values display the following information:
• CAUSE OF TRIP: This message displays the cause of the current trip. If no trip is
present, the display indicates
will override the currently selected default message.
The possible causes of trip are: OVERLOAD, GROUND FAULT, SINGLE PHASE, THERMISTOR,
ACCELERATION TIME, STALLED ROTOR, PLANT INTERLOCK, LOCAL ISOLATOR,
UNDERCURRENT, UNDERPOWER, SERIAL LINK FAIL, INTERNAL FAULT, ANALOG INPUT LOW,
ANALOG INPUT HIGH, EMERGENCY STOP, PROCESS INTERLOCK A-J, PROCESS STOP,
FACEPLATE STOP, OPEN CONTROL, CIRCUIT UNDER VOLTAGE, OVERVOLTAGE, and
PARAMETERS NOT SET
• CAUSE OF LAST TRIP: This message displays the last trip to take place. It is used as a
reference for the pretrip phase and ground currents.
• TIME TO RESET: This message is visible only when an overload trip is present. The time
left before the overload trip can be reset is displayed. Note that the lockout reset
interlock feature can be used to override this time.
• PRETRIP A, B, C: This message displays the motor phase current that was flowing at
the time of trip.
• PRETRIP GROUND CURRENT: This message displays the ground leakage current that
was flowing from any phase to ground at the time of trip.
Pretrip values for current related trips are stored in the EEPROM at the time of trip. This
enables the MM3 Motor Manager 3 to "remember" pretrip values if power is removed. This
feature is enabled for overload, single-phase, undercurrent, underpower, acceleration
time, stalled rotor, and ground fault trips. When a trip not listed above occurs and power is
removed, the MM3 Motor Manager 3 displays zero for pretrip values.
