RUNNING: Whenever contactor A and/or B relays are closed and the contactor status inputs acknowledge
the correct state, the RUNNING indicator will be on. Current flow does not affect the indicator, only contac-
tor status.
•
STOPPED: If both contactors A and B are in the OFF state, the STOPPED indicator will be on.
•
TRIPPED: If a trip condition causes the A or B contactor relays to de-energize, this indicator will be on. As
long as this indicator is on, the motor cannot be started. It is cleared using the reset key, lockout reset facil-
ity or serial port reset, dependent on the type of trip.
•
ALARM: If an alarm condition is present this indicator will be on. Use A2: STATUS \ ALARM DATA to view cur-
rent alarm status.
