5.3 A2 STATUS 5.3.1 DESCRIPTION
This page contains information on the status of the MM2 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 sec-
tions, TRIP DATA, ALARM DATA and MOTOR STATUS.

TRIP DATA
Pretrip values for current related trips are stored in the EEPROM at the time of trip.
This enables the MM2 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
MM2 displays zero for pretrip values.
CAUSE OF TRIP:
NO TRIP
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 pos-
sible 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 PARAMETERS NOT SET
CAUSE OF LAST TRIP:
PARAMETER NOT SET
This message displays the last trip to take place. It is used as a refer-
ence for the pretrip phase and ground currents.
TIME TO RESET =
10 MINUTES
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 = 238
B = 74 C = 74
This message displays the motor phase current that was flowing at the
time of trip.
PRETRIP GROUND
CURRENT = 2.4 AMPS
This message displays the ground leakage current that was flowing
from any phase to ground at the time of trip.
