To avoid SERIOUS PERSONAL
INJURY or DEATH from
electrocution
, disconnect electric
power BEFORE manually moving
limit nuts.
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.
ENTRAPMENT PROTECTION ACCESSORIES (OPTIONAL)
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.
WIRING:
For wiring of your sensing device to the operator,
refer to the wiring diagram supplied with your operator. See
field connection terminals identified as Safety Device.
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.
LIMIT SWITCH ADJUSTMENT
1. To adjust limit nuts depress retaining plate
to allow nut to spin freely. After adjustment,
release plate and ensure it seats fully in
slots of both nuts.
2. To increase door travel, spin nut away from
actuator. To decrease door travel, spin limit
nut toward actuator.
3. Adjust open limit nut so that door will stop
in open position 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 actuator is engaged as
door fully seats at the floor. (Figure 8)
IMPORTANT NOTE:
Make sure the limit nuts are positioned
between the limit switch actuators before proceeding with
adjustments.
