Track Mounted Beam Sensor -
- Disconnect Power Supply before any installation or repair
- Wear Safety Glasses
The door opener will not operate until the beam
sensor is connected to the power unit and properly aligned. The invisible beam of
light must not be obstructed, otherwise the door can be closed by maintaining constant
pressure on the wall mounted pushbutton only. The transmitter can not be used to
close the door. The door can be opened using either the hand-held transmitter or
wall-mounted pushbutton even if the beam is not aligned or connected to the power unit.
Pull emergency release cord to disconnect door from opener, then manually close
door before continuing.
These mounting brackets have been designed to replace the
bottom track brackets on Stanley Garage Doors. See Fig 1. They can also be
mounted directly to the wall using lag screws. Do NOT loosen or remove any brackets
that are connected to springs.
The beam sensor assembly MUST be mounted in such a
manner as to cover the area as close to the bottom edge of the door as possible and NO
MORE THAN five (5) inches above the door to provide maximum entrapment protection.
Beam Sensor Mounting
- Begin by attaching the sending and receiving units to the
inside of the two "U" shaped adjustment brackets using thumb screws. The
front mounting hole of these units should be secured in the curved adjustment slot in the
brackets. See Fig. 2.
- If you are using the beam sensor track brackets to replace the
bottom track brackets, the 1/4" carriage bolts are used to attach the beam sensor
track brackets to the track and the lag screws connect them to the wall. Make sure
the heads of the carriage bolts are positioned inside the track and the 1/4" nuts are
inside the bracket.
- If track mounting is not possible, use the lag screws to
attach the brackets to the wall. The sending and receiving units should be mounted
at least 12" to the side of the door opening to minimize any interference by the sun.
In some installations it may be necessary to attach wooden spacers to the wall to
achieve the required clearance. Expansion bolts (not supplied) may be required to
attach the brackets to walls constructed of materials other than wood or gypsum. See
Fig. 3. The small "SENDING" unit should be mounted on the side of the door
most likely to be exposed to the sun.
- Once the beam sensor track brackets are firmly mounted, the
"U" shaped brackets containing the sending and receiving units can be attached
using the remaining thumb screws at this time.
- Connect the sending and receiving units together using the
connection wire provided. The connectors simply plug together. If the wires
must be lengthened, use wire nuts or a suitable connector. One wire has a white
stripe. Be sure to observe polarity. Temporarily tack the wires into place
NOTE: The Connection wire may
not be supplied. Sending and receiving units may be pre-connected at the factory.
- Uncoil the remaining loop of wire with the small 2 pin
connector that is attached to the receiving unit. Route the wire up the garage wall
across the ceiling and down to the power unit. Temporarily tack the wire into place
- Locate the 2 pin obstruction sensor plug on the back of the
power unit. Carefully plug the connector onto the 2 metal tabs located inside the notch at
the rear of the power unit. Make sure the locking tab is properly inserted as shown.
See Fig. 4. Leave a small loop of wire that attaches to the rear of the door
opener power unit. This is to ensure that the connector will not pull off the tabs
if the power unit moves during operation.
**Carefully loop and secure any additional wire in a safe location where it will not
interfere with the operation of the door. Secure all staples but DO NOT staple
through the wires.
TO REDUCE THE RISK OF ELECTRIC SHOCK, CONNECT THE
POWER CORD ONLY TO A PROPERLY GROUNDED 3-PRONG 120 VOLT OUTLET. DO NOT USE AN
EXTENSION CORD OR CHANGE THE PLUG IN ANY WAY. IF THE PLUG DOES NOT FIT INTO
THE OUTLET, CONTACT A QUALIFIED ELECTRICIAN TO INSTALL THE PROPER OUTLET. AS SOON AS
THE POWER IS APPLIED TO THE UNIT, THE LIGHT ON THE OPENER SHOULD BLINK ONCE.
Beam Sensor Alignment
- The beam sensor can be aligned by moving the sending and
receiving units up or down and in or out until the red light on the alignment light
comes on. The thumb screws that attach the sending and receiving units to the
"U" bracket can be loosened to pivot the bracket up or down, and the thumb
screws that attach the "U" brackets to the larger beam sensor track brackets can
be loosened to move the brackets in or out. See Fig. 5.
- Once the red alignment light comes on, pivot the units up or
down and move them in or out until you find the center of the operating angle.
Tighten all thumb screws when the system is centered. This will prevent
possible operating problems that may occur if the system is not aligned in the center of
the operating angle.
- Check to make sure all wire is secured with the staples, and
that all the mounting bolts and thumb screws are tightened.
Beam Sensor Testing
- Pull the manual disconnect straight down and allow the
mechanism to engage in slot.
- Manually move door until traveler engages with traveler hitch.
**CAUTION - The opener will operate during the following steps. Insure nothing is in
the path of the door before proceeding. Do not stand in the pathway of the door.
- Push the handheld transmitter to close the door. While
the door is closing, test the beam sensor by obstructing the invisible beam. When
obstructed, the red alignment light on the receiving unit should turn off. The
closing door should stop, pause 2 seconds, and reverse and begin opening. The lights
on the door opener should flash.
Obstructing the beam while the door is opening will have no effect.
If the red alignment light on the receiving unit does not
come on or if the garage door will not close using the handheld transmitter, perform the
- Make sure the garage door opener is plugged in and properly
grounded using a 3-prong, 120 volt outlet.
- Make sure 2 pin connector on rear of opener is properly
attached with the locking tab as shown in Fig. 4.
- Align system by moving sending and receiving units up and down
or in and out as shown in Fig. 5.
- If the sending or receiving units are mounted in the sun, the
red alignment light may be on, but the system may still not operate correctly.
Manually close garage door to block the sun, then try operating the opener while it
is disconnected. Relocate the sending and receiving units if necessary.
- Check for a break or a short in one of the wires.
- Make sure nothing is obstructing the invisible beam.
Check the door, door tracks, handle and lift cord.
- If the hand-held transmitter will not OPEN the door, check
transmitter code and battery.
- If the door fully closes, then opens, check the "Close
Travel" adjustment on the opener.
- Periodically clean any dirt off the front of the sending and
receiving units using a clean cloth.
