10.2 HAND/OFF/AUTO CONFIGURATION
10.2.1 2-WIRE HAND / 2-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 immediately. In the auto position, the starter is ener-
gized by the maintained PLC contact. When the PLC contact opens, the motor stops.
To program the MM2 for two-wire hand / two-wire auto 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
.
10.2.2 CONTROL OPERATION
HAND:
•
In the hand position, the motor will run.
•
Pressing the STOP key causes a latched trip. The motor cannot be restarted until the RESET
key is pressed.
OFF:
•
In the off position, the motor will stop.
AUTO:
•
In the auto position, the motor is available to start.
•
When the PLC contact closes, the motor runs.
•
When the PLC contact opens, the motor stops.
•
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 Status N.O. input within one second of closing the
Contactor A output relays, an OPEN CONTROL CIRCUIT alarm will occur. This causes the Contac-
tor A output relay to open.
In the case of a FACEPLATE STOP trip, the start signal to terminal 12 should be removed if restart-
ing is not desired. When the reset key is pressed on the MM2, the motor will be restarted based on
terminal 12.
