10 CONTROL WIRE APPLICATIONS
This control scheme is used when a maintained contact is in series with the starter coil. When the
PLC contact is closed the motor runs. When the PLC contact opens the motor stops.
To program the MM2 for two-wire control, set:
S3 PROCESS\PROGRAMMABLE INPUTS\INTERLOCK INPUT 1: TWO WIRE CONTROL
S3 PROCESS\STOP CONFIGURATION\FACEPLATE STOP: LATCHED
The INTERLOCK INPUT 1 setpoint was chosen to match the wiring diagram provided. Any of
the available Interlocks 1 through 10 could be programmed for TWO WIRE CONTROL.
NOTE
START:
• Start command received (switch input) and maintained.
STOP:
• Start command removed.
• Pressing the STOP key causes a latched trip. The motor cannot be restarted until the RESET
key is pressed.
Terminal 11 (Stop input) must be closed to allow a start. The MM2 display will read "Motor Status
Unavailable" when the stop input is open.
If feedback is not received by the Contactor A relay Status N.O. inputs within 1 second of closing
Contactor A output relay, an OPEN CONTROL CIRCUIT alarm will occur. This will cause Contactor
A output relay to open.
