PREPARATION

It is imperative that the wall or mounting surface provide adequate support for the operator.

This surface must:

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.

The safety and wear of the operator will be adversely affected if any of the above requirements are not met. For metal buildings, fasten 2" x 2" x 3/16" (or larger) angle iron frames to the building purlins. Retain 5-1/2" (13.97 cm) between frames.

Both J and H series operators have dual output shafts and may be mounted on either the right (standard) or left side of door, and in either a vertical (standard) or horizontal mounting position. If you need to move the drive sprocket, loosen BOTH set screws, remove the sprocket and key, and place on the opposite side of the drive shaft. Be sure to tighten BOTH set screws securely.

HAND CHAIN HANDING

For models H and HJ with manual hoist hand chain systems, the handing of the operator must be determined at the time of order. The handing is indicated by last letter of the model name (R or L). The hand chain wheel can not be switched on site. If your installation causes the hand chain to hang in the door opening, hook the chain off to the side near the top of the door jamb.

To prevent possible SERIOUS INJURY or DEATH:

• DO NOT connect electric power until instructed to do so.

• If the door lock needs to remain functional, install an interlock switch.

• ALWAYS call a trained professional door serviceman if door binds, sticks or is out of balance. An unbalanced door may not reverse when required.

• NEVER try to loosen, move or adjust doors, door springs, cables, pulleys, brackets or their hardware, ALL of which are under EXTREME tension and can cause SERIOUS PERSONAL INJURY.

• Disable ALL locks and remove ALL ropes connected to door BEFORE installing and operating door operator to avoid entanglement.

ENTRAPMENT PROTECTION ACCESSORIES (OPTIONAL)

PHOTO EYES & SENSING EDGES

Sensing devices provided for door industry type operators with an isolated normally open (N.O.) dry contact output are compatible with your operator. This includes pneumatic and electric edges, and through beam and retro reflective photo eyes. If you would like to order or receive more information on safety devices, please contact your local Authorized Dealer.

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.

Important Notes:

a. Proceed with Limit Switch Adjustments described below before

making any sensing edge wiring connections to operator.

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 diagrams provided on pages 13 and 14. See field connection terminals identified as Reversing Device.

TAKE-UP REEL

Take-up reel should be installed 12" (30.48 cm) above the top of the door.

COIL CORD

Connect operator end of coil cord to junction box (not provided) fastened to the wall approximately halfway up the door opening.

ADJUSTMENT

To avoid SERIOUS PERSONAL INJURY or DEATH from electrocution, disconnect electric power BEFORE manually moving limit nuts.

WARNING

LIMIT SWITCH ADJUSTMENT

NOTE: Make sure the limit nuts are positioned between the limit switches before proceeding with adjustments.

1. Depress retaining plate to allow nut to spin freely. After adjustment, release plate and move nut back and forth to ensure it is fully seated in slot.

2. To increase door travel, spin nut away from limit switch. To decrease door travel, spin limit nut toward limit switch.

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 the limit switch is engaged as door fully seats at the floor.

INSTALLATION

To reduce the risk of SEVERE INJURY or DEATH, ALWAYS install reversing sensors when the 3-button control station is out of sight of door or ANY other control (automatic or manual) is used. Reversing devices are recommended for ALL installations.

BRAKE ADJUSTMENT

A solenoid brake is available as an option (not included as a standard feature). The brake is adjusted at the factory and should not need additional adjustment for the the life of the brake assembly.

Replace brake assembly when necessary. Refer to the illustration for identification of components for the solenoid type brake system.

ADJUSTMENT

CLUTCH ADJUSTMENT AND AUXILIARY REVERSAL SYSTEM

The Auxiliary Reversal System is designed to protect the door and motorized operator. It is NOT a substitute for a safety sensing device. The Auxiliary Reversal System works in tandem with the adjustable clutch to detect if a closing door runs into or comes across an obstruction. If an obstruction is met and causes the clutch to slip, the Auxiliary Reversal System will return the door to the full open position when closing or stops the door when opening.

1. Remove cotterpin from nut on the clutch shaft.

2. Back off clutch nut until there is very little tension on the clutch spring.

3. Tighten clutch nut gradually until there is just enough tension to permit the operator to move the door smoothly but to allow the clutch to slip if the door is obstructed. When the clutch is properly adjusted, it should generally be possible to stop the door by hand during travel.

4. Reinstall cotterpin.

To prevent possible SERIOUS INJURY or DEATH, install reversing sensors when the 3-button control station is out of sight of the door or ANY other control (automatic or manual) is used. Reversing devices are recommended for ALL installations.

POWER WIRING & GROUND WIRING

To reduce the risk of SEVERE INJURY or DEATH:

• ANY maintenance to the operator or in the area near the operator MUST NOT be performed until disconnecting the electrical power and locking-out the power via the operator power switch. Upon completion of maintenance the area MUST be cleared and secured, at that time the unit may be returned to service.

• Disconnect power at the fuse box BEFORE proceeding. Operator MUST be properly grounded and connected in accordance with local electrical codes. The operator should be on a separate fused line of adequate capacity.

• ALL electrical connections MUST be made by a qualified individual.

• DO NOT install ANY wiring or attempt to run the operator without consulting the wiring diagram. We recommend that you install an optional reversing edge BEFORE proceeding with the control station installation.

• ALL power wiring should be on a dedicated circuit and well protected. The location of the power disconnect should be visible and clearly labeled.

• ALL power and control wiring MUST be run in separate conduit.

WARNING

GROUND WIRING CONNECTIONS

1. Connect earth ground to the chassis ground screw in the electrical box enclosure.

2. Use same conduit entry into the electrical box as the power

wiring.

IMPORTANT NOTE: This unit must be properly grounded. Failure to properly ground this unit could result in electric shock and serious injury.

POWER WIRING CONNECTIONS

1. Connect power wires coming from the main to the captive terminal block in the electrical box enclosure marked with the label. All power and control wiring must be run in separate conduit in accordance with local electrical codes.

2. Be sure to run all power wires through the conduit hole in the electrical box enclosure marked with the label shown below.

NOTE: Must use #14 AWG or thicker wire for power wiring.

ON THREE PHASE MACHINES ONLY: Incorrect phasing of the power supply will cause the motor to rotate in the wrong direction. To change motor rotation, exchange incoming power leads L1 and L2.

CONTROL STATION WIRING & INSTALLATION

CONTROL WIRING CONNECTIONS

1. Connect control wires to the P1 terminal block located on the logic board as shown.

2. Connect conduit with all control wires through the conduit hole in the electrical box enclosure marked with the label shown below.

3. Apply power to the operator. Press OPEN push button and observe direction of door travel and then Press the STOP

button.

If door did not move in the correct direction, check for improper wiring at the control station or between operator and control station. NOTE: In “Diag” mode the 3-button control station can be

tested to verify correct wiring of Open, Close and Stop buttons without moving the door.

If the door moves in the wrong direction and or the limits move in the wrong direction, simply move the motor direction jumper located on the logic board from the factory default setting (STD) to the (REV) pins. This will change the motor rotation as well as the functional position of the OPEN and CLOSE limit switch’s. Then relocate the safety limit switch (SLS) only to the opposite side with the new functional close limit location. Orient the arm (lever) of the limit switch away from the center. NOTE: The motor

direction change is not available on the DJ and DH models.

EXTERNAL RADIO WIRING CONNECTIONS

On all models a radio terminal bracket marked R1 R2 R3 is located on the outside of the electrical enclosure. In B2 mode the operator will then open a fully closed door, close a fully open door, stop an opening door, and reverse a closing door from the radio remote. In TS control wiring the operator will only open the door or reset the timer to close. However, for additional door control from a 3-button remote, a commercial three-channel radio receiver (with connections for OPEN/CLOSE/STOP) is recommended.

NOTE: If an external radio receiver is being used in place of the built-in receiver, remove or disconnect the coaxial cable from the logic board.

MOUNTING INSTRUCTIONS

1. Mount WARNING NOTICE beside or below the control station.

2. Mount MAINTENANCE ALERT label to either side of control station.

3. Mount control station(s) within line of sight of door(s).
