APPLICATION
INTRODUCTION
This Medium Duty Commercial Door Operator includes a number of features that will provide years of reliable and safe operation.
Features:
- Supports both monitored and non-monitored safety devices: Safety devices detect obstructions in the door's path and automatically reverse a closing door. Safety devices are highly recommended by the manufacturer.
- Radio receiver: A factory installed radio receiver allows remote controls, keyless entries and other remote command devices to be programmed to the operator.
- Timer To Close: The Timer To Close feature allows the door to automatically close after a preset time (only available with B2 wiring and a monitored safety device).
- Wiring Types: The functionality of the operator is based on the wiring type. The operator is shipped from the factory in standard C2 wiring type (factory default). Some wiring types will require an optional safety device. Refer to Basic Programming Section for descriptions of wiring types, requirements and programming.

PREPARATION
PREPARING YOUR DOOR
The manufacturer recommends 3' (91.4 cm) of clearance around the operator for serviceability. Before you begin:
- Disable locks.
- Remove any ropes connected to door.
- Before the operator is installed, be sure the door has been properly aligned and is working smoothly. Although each installation will vary due to particular building characteristics, refer to the following general procedures to install the operator.
▲ WARNING 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.
ASSEMBLY

TYPICAL INSTALLATION
DETERMINE HEADER BRACKET MOUNTING LOCATION
The trolley operator is generally mounted over the center of the door. However, off center mounting may be required due to interfering structures or location of door stile / top section support. Typically, the operator may be mounted up to 24" (60.96 cm) off center on torsion spring doors. Extension springs require center mounting.

Diagram: Shows positioning the header bracket and drilling pilot holes. A measurement of 4" (10 cm) is indicated.
CAUTION To prevent possible SERIOUS INJURY or DEATH:
- Header bracket MUST be RIGIDLY fastened to structural support on header wall or ceiling, otherwise door might not reverse when required. DO NOT install header bracket over drywall.
- Concrete anchors MUST be used if mounting header bracket or 2x4 into masonry.
- NEVER try to loosen, move or adjust door, springs, cables, pulleys, brackets, or their hardware, ALL of which are under EXTREME tension.
- ALWAYS call a trained door systems technician if door binds, sticks, or is out of balance.
4 Secure header bracket

TYPICAL INSTALLATION
▲ WARNING 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.
- Reversing devices are recommended for ALL installations.
- 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.
POWER AND GROUND WIRING CONNECTIONS
NOTE: Power and control wiring must be run in separate conduit in accordance with local electrical codes. Must use 14 AWG or heavier wire for power wiring. Use conduit knockouts for wiring as indicated on the electrical box labels.
IMPORTANT NOTE: Operator must be properly grounded. Failure to properly ground the operator could result in electric shock and serious injury.

NOTE: When retaining plate is released, verify that the retaining plate is fully seated with the notches of the limit nut.
ADJUSTMENT
2 Adjust the clutch
- Apply power to operator
- Turn clutch nut to release tension.
- Re-tighten nut until there is just enough tension to permit smooth operation.
- Secure clutch nut with cotter pin.
Diagrams: Show removing the tape holding the cotter pin, inserting the cotter pin, and bending its ends to secure the clutch nut. Arrows indicate "To Loosen" and "To Tighten" on the clutch nut.
OPTIONAL SAFETY DEVICE CONFIGURATIONS
To protect against accidental entrapment or injury from a moving door it is recommended that a safety device (sensing edge or photo eyes) be installed.
IMPORTANT INFORMATION ABOUT SAFETY DEVICES
PHOTO EYES
When properly connected and aligned, the photo eye will detect an obstruction in the path of its invisible light beam. If an obstruction breaks the light beam while the door is closing, the door will stop and typically reverse to the full open position. The photo eyes must be installed facing each other across the door, no more than 6" (15 cm) above the floor.
Diagram: Shows photo eyes installed on a garage door.
SENSING EDGES
When properly connected, the sensing edge will make contact with an obstruction while the door is closing, the door will stop and typically reverse to the full open position. The sensing edge must be installed on the bottom of the door.
Diagram: Shows a sensing edge installed on the bottom of a garage door.
See Optional Safety Device Configurations for wiring information.
OPTIONAL SAFETY DEVICE CONFIGURATIONS
