MESSAGE
This message indicates the name and status of the motor. The top line of
the display (20 characters) can be programmed to a user defined
alphanumeric name. The second line indicates motor status. The
following list shows the possible motor status indications:
• Unavailable : There is at least one condition present that is preventing
start commands from operating. Possible conditions are: a trip is
present, the STOP
open, one of the Process Interlock switches is open, an undervoltage
delayed restart is in progress, an Autotransformer Start Inhibit is in
progress, or the STARTER TYPE setpoint is OFF.
• Available-Auto : Start commands from the serial port or the Auto Start
A / Auto Start B interlock switch inputs will be performed. Start com-
mands from the Start A / Start B switch inputs and the
START B keys will be ignored.
• Available-Manual : Start commands from the Start A / Start B switch
inputs and/or the
mands from the serial port and Auto Start A / Auto Start B switch
inputs will be ignored.
• Running : At least one contactor output relay is closed.
This message displays the actual RMS current in each phase in amps.
Format: 10.0 at CT Primary ≤ 50 A
100 at CT Primary > 50 A.
This message displays the ground fault leakage current flowing from any
phase to ground in amps.
This message displays the motor load as a percentage of full load current
(FLC). The motor load is calculated as the average of the three motor
phase currents. When the value exceeds 100%, an overload condition
exists. The MM3 eventually trips if the current is not reduced below 100%
of FLC × SERVICE FACTOR.
