Be sure power to the opener is disconnected.

The sending eye transmits an invisible light beam to the receiving eye. The units can be installed on either side of the garage door as long as the sun never shines directly into the receiving eye lens.

Look at the label on the connector end of each case to identify the sensors.

The brackets must be connected and fastened so that the sending and receiving eyes face each other as shown in Figure 1.

If an obstruction breaks the light beam while the garage door is closing, the door will stop and reverse to full open position and the opener lights will flash for 5 seconds.

The brackets

must

be securely fastened to a solid surface such as the studs on either side of the door, or add a piece of wood at each location if installing in masonry construction.

The invisible light beam path must be unobstructed. No part of the garage door (or door tracks, springs, hinges, rollers or other hardware) can interrupt the beam while the door is closing. If it does, use a piece of wood to build out each sensor mounting location to the minimum depth required for light beam clearance.

installation requirements better. Make sure the wraps

and brackets are aligned so the sensors will face each other across the garage door.

• Fasten the "C" wraps to the mounting brackets

having square holes, using the hardware shown in Figure 2.

WALL INSTALLATION ONLY

• Connect each assembly to a slotted bracket, using the hardware shown in Figure 3. Note alignment of

brackets for left and right sides of the door.

• Finger tighten the lock nuts.

• Use bracket mounting holes as a template to locate and drill (2) 3/16" diameter pilot holes on both sides of the garage door, 4"-6" above the floor (but not exceeding 6"). See Warning on page 16.

• Attach bracket assemblies with 1/4"x1-1/2" lag screws as shown in Figure 3.

• Adjust right and left side bracket assemblies to the same distance out from mounting surface. Make sure all door hardware obstructions are cleared. Tighten the nuts securely.

DOOR TRACK INSTALLATION ONLY

• Discard slotted bracket. Drill 3/8" holes in each track and fasten securely with hardware as shown in Figure 4. See Warning on page 16 regarding height of sensor beam.

Installation Step 11

CAUTION

Fasten Door Bracket & Plate

To prevent damage to steel, aluminum, fiberglass or glass panel doors, always reinforce the inside of the door both vertically and horizontally with an angle iron.

A horizontal brace should be long enough to be secured to 2 vertical supports. A vertical brace should cover the height of the top panel.

The illustration shows one piece of angle iron as the horizontal brace. For the vertical brace, 2 pieces of angle iron are used to create a "U"-shaped support. The best solution is to check with your garage door manufacturer for an opener installation, door reinforcement kit.

Figure 1

• Center the door bracket on the previously marked vertical guideline used for the header bracket installation.

• Position the bracket on the face of the door within the following limits:

A) The top edge of the bracket 2"-4" below the top

edge of the door.

B) The top edge of the bracket directly below any

structural support across the top of the door.

• Mark and drill 5/16" left and right fastening holes. Secure the bracket as shown in Figure 1 if there is vertical reinforcement.

If your installation doesn't require vertical reinforcement but does need top and bottom fastening holes for the door bracket, position the door plate over the door bracket as shown in Figure 2. Fasten securely with hardware shown in Figure 1.

Situation Probable Cause & Solution

The opener doesn't operate from either the Door Control or a remote control:

Opener operates from a remote control, but not from Door Control:

A remote control has short range:

1. Have you disabled all door locks? Review installation instruction warnings on page 7.

2. Does the opener have electric power? Plug a lamp into the outlet. If it doesn't light, check the fuse box or the circuit breaker. (Some outlets are controlled by a wall switch.)

3. Repeated operation may have tripped the overload protector in the motor. Wait 15 minutes. Try again.

4. Is there a build-up of ice or snow under the door? The door may be frozen to the ground. Remove any restriction.

5. Remove the bell wire from the opener terminal screws. Short the red and white terminals by touching both terminals at the same time with a piece of metal (screwdriver or coin). If the opener runs, check for a faulty wire connection at the door control or a short under the staples.

1. Are the wiring connections correct? Review Step 6, page 13.

1. Check the battery test light. If the light is dim, change the battery.

2. Change the location of the remote control in the car.

3. A metal door, foil-backed insulation or metal garage siding will reduce the transmission range.

4. Check to be sure the antenna on the back panel of opener extends fully downward.

Install Antenna Kit, Part No. 41A3504, to increase range.

Opener noise is disturbing in living quarters of home:

The garage door opens and closes by itself:

The door doesn't open completely:

The door doesn't close completely:

1. If operational noise is a problem because of proximity of the opener to the living quarters, the Vibration Isolator Kit 41A3263 can be installed. This kit was designed to eliminate the "sounding board effect" and is easy to install.

1. Check to be sure that a remote control push button is not stuck in the "down" position.

2. Remove the bell wire from the Door Control terminals and operate from a remote control only. If this solves the problem, the Door Control is faulty (replace), or there is an intermittent short on the wire between the Door Control and the opener.

1. Is something obstructing the door?

2. If door opens at least 5 feet, the travel limits may need to be increased. One turn equals 2 inches of travel. See page 21.

Repeat the safety reverse test after the adjustment is complete.

3. If the door has been working properly but now doesn't open all the way, increase the

up force.

Repeat the safety reverse test after the adjustment is complete.
