IMPORTANT SAFETY NOTES

CAUTION

TO AVOID DAMAGE TO DOOR AND OPERATOR, MAKE ALL DOOR LOCKS INOPERATIVE. SECURE LOCK(S) IN "OPEN" POSITION.

IF THE DOOR LOCK NEEDS TO REMAIN FUNCTIONAL, INSTALL AN INTERLOCK SWITCH.

DO NOT CONNECT ELECTRIC POWER UNTIL INSTRUCTED TO DO SO.

WARNING

KEEP DOOR BALANCED. STICKING OR BINDING DOORS MUST BE REPAIRED. DOORS, DOOR SPRINGS, CABLES, PULLEYS, BRACKETS AND THEIR HARDWARE MAY BE UNDER EXTREME TENSION AND CAN CAUSE SERIOUS PERSONAL INJURY. CALL A PROFESSIONAL DOOR SERVICEMAN TO MOVE OR ADJUST DOOR SPRINGS OR HARDWARE.

SITE PREPARATIONS

It is imperative that the wall or mounting surface provide adequate support for the operator. The safety and wear of the operator will be adversely affected if any of the following requirements are not met.

a)Be rigid to prevent play between operator and door shaft.

b)Provide a level base.

c)Permit the operator to be fastened securely and with the drive shaft parallel to the door shaft.

INSTALLATION INSTRUCTIONS

TYPICAL HOLLOW SHAFT INSTALLATION

1.Slide the shaft collar supplied over the door shaft to desired position and secure in place.

2.Slide the operator on the door shaft until it is laying against the shaft collar. Insert the 4-1/2” key supplied into the operator and the door shaft.

4.Slide the second shaft collar on the door shaft until it is laying against the operator and secure in place, this will hold the 4-1/2” key in place.

5.Secure mounting bracket to wall (pad out as necessary).

NOTE: For additional help refer to the illustrations below.

2.Install a shaft collar onto each end of the through shaft until they are laying against the operator and secure in place, this will hold the 4-1/2” key in place.

3.Install the 12 tooth sprocket onto the though shaft with the 1/1/2” key supplied.

4.Install the door sprocket supplied to the door shaft and connect the operator to the door with chain supplied.

ENTRAPMENT PROTECTION ACCESSORIES (OPTIONAL)

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.

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

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

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 stating 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 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.

POWER WIRING CONNECTIONS

Remove the cover from the wall mounted starter. Inside this enclosure you will find the wiring diagram(s) for your unit. Refer to the wiring diagrams for all connections described below. If this diagram is missing, call the number on the back of this manual. DO NOT INSTALL ANY WIRING OR ATTEMPT TO RUN THIS OPERATOR WITHOUT CONSULTING THE WIRING DIAGRAM.

POWER WIRING

1.Be sure that the power supply is of the correct voltage, phase, frequency, and amperage to supply the operator. Refer to the operator nameplate on the cover.

2.Using the 7/8” dia conduit access knockout as shown below, bring supply lines to the wall mounted starter and connect wires to the terminals indicated on the WIRING CONNECTIONS DIAGRAM.

DO NOT TURN POWER ON UNTIL YOU HAVE FINISHED MAKING ALL POWER AND CONTROL WIRING CONNECTIONS AND HAVE COMPLETED THE LIMIT SWITCH ADJUSTMENT PROCEDURE.

CAUTION: THIS UNIT MUST BE PROPERLY GROUNDED. A GROUND SCREW IS SUPPLIED IN THE ELECTRICAL BOX FOR CONNECTION OF THE POWER SUPPLY GROUND WIRE. FAILURE TO PROPERLY GROUND THIS UNIT COULD RESULT IN ELECTRIC SHOCK AND SERIOUS INJURY.

WARNING

DISCONNECT POWER AT THE FUSE BOX BEFORE PROCEEDING.

OPERATOR MUST BE PROPERLY GROUNDED AND CONNECTED IN ACCORDANCE WITH LOCAL ELECTRICAL CODES. NOTE: THE OPERATOR SHOULD BE ON A SEPARATE FUSED LINE OF ADEQUATE CAPACITY.

ALL ELECTRICAL CONNECTIONS MUST BE MADE BY A QUALIFIED INDIVIDUAL.

WARNING

TO AVOID DAMAGE TO DOOR AND OPERATOR, MAKE ALL DOOR LOCKS INOPERATIVE. SECURE LOCK(S) IN "OPEN" POSITION.

IF THE DOOR LOCK NEEDS TO REMAIN FUNCTIONAL, INSTALL AN INTERLOCK SWITCH.

CONTROL WIRING

DETERMINE WIRING TYPE

Refer to the wiring diagram located on the inside cover the electrical box to determine the type of control wiring.

WIRING TYPES

Standard C2 or B2 Wiring

Standard operators are shipped from the factory with jumper set for C2 wiring, which requires constant pressure on button to close the door. If momentary contact on close direction is desired (B2 wiring) you must include an entrapment protection device. See close control jumper setting below.

Constant pressure on close (C2 wiring)

Red jumper wire was placed on terminal #2 in electrical enclosure. The operator will require constant pressure on close control in order to keep door moving in the close direction.

Momentary contact on close (B2 wiring)

Move red jumper wire from terminal #2 to terminal #3. The operator will require only momentary

contact to close the door.

SPECIAL CONTROL WIRING

If your operator was shipped from the factory with non-standard control wiring or with optional accessories that require addition instructions, refer to the wiring diagram(s) indicated in the special control wiring data box. When a replacement wiring diagram is present, wiring diagrams in this manual will not apply. Refer only to the replacement wiring diagram for all connections.

IMPORTANT NOTE: If your wiring diagram is missing, or you are unsure of the wiring type for your operator, contact the customer service department @ 1-800-528-2806.

LOCATING THE CONTROL STATION

All operators are supplied with a three button station (OPEN/CLOSE/STOP) incorporated into the wall mounted starter. Mount the wall mounted starter where the door is visible, but away from the door and its hardware.

MOUNT WARNING NOTICE

IMPORTANT: Mount WARNING NOTICE beside or below the wall mounted starter.

WARNING

INSTALL THE WALL MOUNTED STARTER WHERE THE DOOR IS VISIBLE, BUT AWAY FROM THE DOOR AND ITS HARDWARE. IF STARTER CANNOT BE INSTALLED WHERE DOOR IS VISIBLE, OR IF ANY DEVICE OTHER THAN THE CONTROL STATION IS USED TO ACTIVATE THE DOOR, A REVERSING EDGE MUST BE INSTALLED ON THE BOTTOM OF THE DOOR. FAILURE TO INSTALL A REVERSING EDGE UNDER THESE CIRCUMSTANCES MAY RESULT IN SERIOUS INJURY OR DEATH TO PERSONS TRAPPED BENEATH THE DOOR.
