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.

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.

WARNING

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) Mounting surface to 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 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 contacts the shaft collar. Insert the 4-1/2” key supplied into the operator and the door shaft.

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

4. Mount torque arm using 5/16-18 x 1” hex bolt to gear box as shown in figures 1 & 2.

NOTE: For additional help refer to the illustrations below.

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.

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. Drill recommended 7/8” dia. holes at approximate locations shown below, and bring supply lines to the wall mounted starter and connect wires to the terminals indicated on the WIRING CONNECTIONS DIAGRAM.

IN ORDER TO KEEP NEMA-4 INTEGRITY, “LIQUIDTITE” CONDUIT CONNECTIONS MUST BE USED.

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

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

IMPORTANT: 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.

DETERMINE WIRING TYPE

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

SPECIAL CONTROL WIRINGWIRING TYPES

Standard C2 Wiring

Standard operators are shipped from the factory set for C2 wiring, which requires momentary contact to open, constant pressure to close, stop on reverse.

If your operator was shipped from the factory with non-standard control wiring or with optional accessories that require additional instructions, refer to the wiring diagram(s) indicated in the special control wiring data box. When a replacement wiring

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 not directly underneath the door, operator, or mounting hardware.

WARNING

Radio Controls

All radio controls must have dry contact relay outputs. Power for radio is to be supplied by an outside source. Do not take power from the components inside the electrical enclosure.

Additional Access Control Equipment

Locate any additional access control equipment as desired (but so that the door will be in clear sight of the person operating the equipment), and connect to the terminal block in the electrical enclosure as shown on the FIELD WIRING CONNECTIONS diagram. Any control with a normally (N.O.) isolated output contact may be connected in parallel with the OPEN button. More than one device may be connected in this manner. Use 16 gauge wire or larger for all controls. DO NOT USE THE CONTROL CIRCUIT TRANSFORMER (24VAC) IN THE OPERATOR TO POWER ANY ACCESS CONTROL EQUIPMENT OTHER THAN A STANDARD RESIDENTIAL TYPE RADIO RECEIVER.

DO NOT USE RADIO CONTROLS WITH YOUR OPERATOR UNLESS YOU HAVE INSTALLED SOME TYPE OF ENTRAPMENT PROTECTION DEVICE. THE USE OF RADIO CONTROLS PRESENTS POTENTIAL HAZARDS DUE TO THE USER’S ABILITY TO OPEN OR CLOSE THE DOOR WHEN OUT OF SIGHT OF THE DOOR.

WARNING

Manual Release Brake

The operator is equipped with a internal interlock switch mounted to the brake assembly. When the brake is manually dis-engaged the control circuit will be disabled, thereby preventing electrical operation of the door from the control devices.
