ENTRAPMENT PROTECTION ACCESSORIES (OPTIONAL)

SAFETY EYES:

Compatible with Liftmaster CPS-LN4 direct connect failsafe
photoeyes.

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.

LIMIT SWITCH ADJUSTMENT

THE LIMIT SWITCHES WILL STOP THE DOOR AT EACH
END OF TRAVEL. ADDITIONAL LIMIT SWITCHES CAN
BE USED FOR CONTROL OF OTHER AUTOMATIC
FUNCTIONS.

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.

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

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
Sensing Device or Safety Edge.

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.

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.

MOTOR OPERATOR MAINTENANCE

Operators require practically no special maintenance other than periodic checking to see that mechanical parts
where necessary are lubricated and the electrical compartments are clear of dirt.

Service technicians should familiarize themselves with the proper sequence of operation and all related controls.
Power to operator must be disconnected when removing or replacing covers on electrical components, making
adjustments, or performing maintenance.

1. Check wire connections for tightness and wire insulation for defects of abrasions.

2. Check to see that all conduit connections are secure.

3. Check wires to safety edge, or infrared safety eyes, if unit is equipped with a safety to reverse feature.

4. Inspect operation of brake.

5. Inspect gearbox for leaks.

6. Inspect roller chain and drive sprockets. Align, lubricate the sprockets, and tighten the set screws.

7. Generally inspect the motor mounting, and tighten the fasteners and bracing.

8. Verify that all conduit connections are tight and have no exposed wires.

9. Inspect the electrical enclosure for debris, arching and moisture. Check for and tighten loose wiring connections.

10. Test motor operation through all control stations.

11. Check limit switch settings.

12. Examine safety edge, coil cord and take-up reel for damage.

13. Test the operation of the safety edge.

14. Check motor amperage draw for a full open and close cycle. Compare readings to those listed on the motor
nameplate

.
