SAFETY EDGE

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) To install a sensing edge, ask for sensing edge con-

nection kit LGOSE. This must be installed in order to add a sensing edge. Refer to instructions and figure 11 on page 9.

b) Proceed with Limit Switch Adjustments before making

any sensing edge wiring connections to operator as described below.

c) Electrician must hard-wire the junction box to the oper-

ator electrical box in accordance with local codes.

TAKE-UP REEL: Take-up reel should be installed 12" above the top of the door.

FORCE ADJUSTMENTS

The open/down force adjustments are made by adjusting two control knobs inside the operator end panel. One knob controls the drive force adjustment. The second knob controls the sensitivity, which is the change of force as seen by the operator.

To set the forces

1. Adjust the drive force to minimum and the sensitivity to minimum.

2. Increase the drive force in 10 degree increments until the door travels freely from limit to limit.

3. Increase the sensitivity in 10 degrees until the door begins to reverse/stop in mid-travel.

4. Decrease the sensitivity by 10 degrees and run the door through a complete cycle to confirm normal operation. Refer to figure 13.

If the door stops normal travel of open/close to the limits, decrease the dive and sensitivity knobs to minimum and repeat steps 2 through 4.
