2.
Open the active contactor A or B.
When the power to the MM3 Motor Manager 3 is interrupted, all output relays 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 by the Contactor A Status N.O. or Contactor B Status N.O. inputs
within one second of closing the corresponding output relay, an OPEN CONTROL CIRCUIT
alarm will occur. This will open the active output relay which will stop the motor.
If feedback remains at Contactor A Status N.O. or Contactor B Status N.O. inputs for more
than one second after opening the corresponding output relay, a welded contactor alarm
will occur.
The Start A input and key are used to start motors A and B. The Start B input and faceplate
key have no effect.
Serial control starts override the mode of operation of the duty/standby starter. For
example a serial start B command will always start motor B and a serial start A will always
start motor A. This is true for Auto Start A and Auto Start B programmable interlock
functions as well.
