CONTROL WIRING
Standard C2 or B2 Wiring
Model MGJ operators are shipped from the factory with
jumper set for C2 wiring, which requires constant pressure
on button to close the door. If momentary contact in close
direction is desired (B2 wiring) you must include an
entrapment protection device. See close control jumper
setting below.
Constant pressure on close (C2 wiring)
Red jumper wire was placed on terminal #2 in the
electrical enclosure. The operator will require constant
pressure on close control in order to keep door moving
in the close direction.
Momentary contact on close (B2 wiring)
Move red jumper wire from terminal #2 to terminal #3.
The operator will require only momentary contact to
close the door.
LOCATING THE CONTROL STATION
All operators are supplied with some type of control station. Generally a three button station (OPEN/CLOSE/STOP) is
provided. A two-position key switch or control station (OPEN/CLOSE) may be added or substituted when requested at the
time of order. Mount the control station near the door.
