10.2.5 3 WIRE HAND / 3 WIRE AUTO
This control scheme is used when it is desirable to operate the starter manually and automatically. In
the Hand position, the starter coil is energized via the START button and de-energized via the STOP
button. In the auto position, the starter is energized automatically when the PLC1 contact is pulsed
closed. When the PLC2 contact is pulsed open, the motor stops.
To program the MM2 for three-wire hand / two-wire auto control, set the MM2 to the default settings.
