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.

NOTE: Before starting adjustment of the limit switches,
loosen or tighten (if necessary) the lock nut in order to
obtain a convenient adjustment tightness of the cam
wheels. After finishing the adjustments, make sure that the
lock nut is sufficiently tight 1 NM (8”LBS) to retain the cam
wheels securely during operation.
When door is in the fully open position, the green cam
wheel (Open) will be turned into contact with its
corresponding switch. In the same way, just before the
door is in the closed position, the black cam wheel (Closed)
will activate its switch.
COARSE ADJUSTMENT
The coarse adjustment of the limit switches can be done by
inserting a rod or a screw driver into one of the adjustment
holes in the cam wheels and by turning each cam wheel
with the rod or screw driver.
FINE ADJUSTMENT
Fine adjustment can be done by screwing the adjustment
screw (supplied) against the cam shaft thread inside each
cam wheel. The screw must be changed from one
adjustment hole into the other for turning the cam wheel in
the opposite direction.
