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.
TAKE-UP REEL: Take-up reel should be installed 12" (30.48 cm)
above the top of the door.
COIL CORD: Connect operator end of coil cord to junction box
(not provided) fastened to the wall approximately halfway up the
door opening.
INSTALLATION
To reduce the risk of SEVERE INJURY or DEATH, ALWAYS
install reversing sensors when the 3-button control station is
out of sight of door or ANY other control (automatic or manual)
is used. Reversing devices are recommended for ALL
installations.

with the bottom of the door even with top of door opening.
4. Repeat steps 1 and 2 for close cycle. Adjust close limit nut so
that the limit switch is engaged as door fully seats at the floor.
