• 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 contactor 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 facility or serial port reset, dependent on the type of trip.
ALARM: If an alarm condition is present this indicator will be on. Use the A2: ALARM DATA actual
