Starter
This starter type is a full voltage starter and allows a single MM3 Motor Manager 3 to
control two identical motors. This starter type has two modes, manual and automatic. In
manual mode a switch input determines which of the two motors is available for
operation. In automatic mode the MM3 Motor Manager 3 selects which motor should run
based on the number of starts performed. An even number of starts will start motor A and
an odd number will start motor B.
To program the MM3 Motor Manager 3 for duty/standby starter, set:
