MGJ LIMIT SWITCH ADJUSTMENT

MAKE SURE THE LIMIT NUTS ARE POSITIONED BETWEEN THE LIMIT SWITCH ACTUATORS BEFORE
PROCEEDING WITH ADJUSTMENTS.

SENSING EDGES

All types of sensing edges with an isolated normally
open (N.O.) output are compatible with your operator.
This includes pneumatic and electric edges.  If your
door does not have a bottom sensing edge and you
wish to purchase one, contact the supplier of your
operator.

If not pre-installed by the door manufacturer, mount the
sensing edge on the door according to the instructions
provided with the edge.  The sensing edge may be
electrically connected by either coiled cord or take-up
reel. Refer to the steps below 

Important Notes:

a) Proceed with Limit Switch Adjustments before

making any sensing edge wiring connections to
operator as described below.

b) Electrician must hardwire the junction box to the

operator electrical box in accordance with local
codes.

ENTRAPMENT PROTECTION ACCESSORIES (OPTIONAL)

IT IS STRONGLY RECOMMENDED THAT A
SENSING EDGE OR OTHER ENTRAPMENT
PROTECTION DEVICE BE USED IN
CONJUNCTION WITH THIS OPERATOR.

TAKE-UP REEL: 

Take-up reel should be installed 12"

above the top of the door.

COIL CORD:  

Connect operator end of coil cord to

junction box (not supplied) fastened to the wall
approximately halfway up the door opening.

If other problems persist, call our toll-free number for
assistance - 1-800-528-2806.
