]] ACTUAL VALUES
]] A2 STATUS
This page contains MM3 status information following an alarm and/or trip. Information such as cause of alarm/
trip and the motor values prior to a trip are included. The page also contains a section describing the control
status of the motor. Actual Values Page 2 is divided into three sections: TRIP DATA, ALARM DATA, and
MOTOR STATUS.

Pretrip values for current related trips are stored in the EEPROM at the time of trip. This
enables the MM3 to "remember" pretrip values if power is removed. This feature is enabled for over-
load, single-phase, undercurrent, underpower, acceleration time, stalled rotor, and ground fault trips.
NOTE
When a trip not listed above occurs and power is removed, the MM3 displays zero for pretrip values.

MESSAGE
This message displays the cause of the current trip. If no trip is present,
the display indicates NO TRIP. When a trip occurs, the cause of trip
message will override the currently selected default message. The
possible causes of trip are:
OVERLOAD
SINGLE PHASE
ACCELERATION TIME
PLANT INTERLOCK
UNDERCURRENT
SERIAL LINK FAIL
ANALOG INPUT LOW
EMERGENCY STOP
PROCESS STOP
OPEN CONTROL
OVERVOLTAGE
This message displays the last trip to take place. It is used as a reference
for the pretrip phase and ground currents.
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.
This message displays the motor phase current that was flowing at the
time of trip.
74
This message displays the ground leakage current that was flowing from
any phase to ground at the time of trip.
