MM3 MOTOR MANAGER 3  – INSTRUCTION MANUAL

2–17

When the power to the MM3 Motor Manager 3 is interrupted, all output relays on the MM3 
Motor Manager 3 will de-energize causing them to open and stop the motor. The MM3 
Motor Manager 3 can only be wired for fail-safe operation.
If feedback is not received from the S or R contacts to the Contactor A or B Status N.O. 
inputs within one second of closing Contactor A or B output relays, an open control circuit 
alarm will occur. This will cause contactor A and B output relays to open. If feedback 
remains at the Contactor A or B Status N.O. input more than one second after opening the 
contactor A or B output relays, a welded contactor alarm will occur.
