INSTALLATION STEP 10Install The Safety Reversing SensorThe safety reversing sensor must be connectedand aligned correctly before the garage dooropener will move in the down direction.IMPORTANT INFORMATION ABOUTTHE SAFETY REVERSING SENSORWhen properly connected and aligned, the sensorwill detect an obstacle in the path of its electronicbeam. The sending eye (with an green indicatorlight) transmits an invisible light beam to thereceiving eye (with a green indicator light). If anobstruction breaks the light beam while the door isclosing, the door will stop and reverse to full openposition, and the opener lights will flash 10 times.The units must be installed inside the garage so thatthe sending and receiving eyes face each otheracross the door, no higher than 6" above the floor.Either can be installed on the left or right of the dooras long as the sun never shines directly into thereceiving eye lens.The mounting brackets are designed to clip onto thetrack of sectional garage doors without additionalhardware.WARNINGBe sure power is not connected to the garage dooropener BEFORE installing the safety reversing sensor.To prevent SERIOUS INJURY or DEATH from a closinggarage door:--Correctly connect and align the safety reversingsensor. This required safety device MUST NOT bedisabled.Install the safety reversing sensor so beam is NOHIGHER than 6" above garage floor.If it is necessary to mount the units on the wall, thebrackets must be securely fastened to a solidsurface such as the wall framing. If installing inmasonry construction, add a piece of wood at eachlocation to avoid drilling extra holes in masonry ifrepositioning is necessary.The invisible light beam path must be unobstructed.No part of the garage door (or door tracks, springs,hinges, rollers or other hardware) may interrupt thebeam while the door is closing.Sensor Beam6" maximumabove floorInvisible Light BeamProtection AreaFacing the door from inside the garageSensor Beam6" maximumabove floor19
INSTALLING THE BRACKETSBe sure power to the opener is disconnected.Install and align the brackets so the sensors will faceeach other across the garage door, with the beam nohigher than 6" above the floor. They may be installedin one of three ways, as follows.Garage door track installation (preferred):Slip the curved arms over the rounded edge ofeach door track, with the curved arms facing thedoor.

INSTALLATION STEP 11Fasten the Door BracketFollow instructions which apply to your door typeas illustrated below or on the following page.A horizontal reinforcement brace should be longenough to be secured to two vertical supports. Avertical reinforcement brace should cover theheight of the top panel.The illustration shows one piece of angle iron as thehorizontal brace. For the vertical brace, two pieces ofangle iron are used to create a "U''-shaped support(Figure 1). The best solution is to check with yourgarage door manufacturer for an opener installationdoor reinforcement kit.NOTE: Many vertical brace installations provide fordirect attachment of the clevis pin and door arm. Inthis case you will not need the door bracket; proceedto Installation Step 12.SECTIONAL DOORSCenter the door bracket on the previously markedvertical centerline used for the header bracketinstallation. Note correct UP placement, asstamped inside the bracket (Figure 2).Position the bracket on the face of the door withinthe following limits:A) The top edge of the bracket 2"-4" below the topedge of the door.B) The top edge of the bracket directly below anystructural support across the top of the door.CAUTIONTo prevent damage to garage door, reinforce inside ofdoor with angle iron both vertically and horizontally.Mark and drill15/16" left and right fastening holes.Secure the bracket as shown in Figure 1 if there isvertical reinforcement.If your installation doesn't require vertical reinforce-ment but does need top and bottom fastening holesfor the door bracket, fasten as shown in Figure 2.Horizontal and vertical reinforcementis needed for lightweight garage doors(fiberglass, aluminum, steel, doors withglass panel, etc).

If it doesn't light, check the fuse box or the circuitbreaker. (Some outlets are controlled by a wall switch.)Have you disabled all door locks? Review installationinstruction warnings on page 10.Is there a build-up of ice or snow under the door? The doormay be frozen to the ground. Remove any restriction.The garage door spring may be broken. Have it replaced.Repeated operation may have tripped the overloadprotector in the motor. Wait 15 minutes and try again.2. Opener operates from the remote, but not from theDoor Control:Is the door control lit? If not, remove the bell wire from themotor unit terminals. Short the red and white terminals bytouching both terminals at the same time with a piece ofwire. If the opener runs, check for a faulty wire connectionat the door control, a short under the staples, or a brokenwire.Are the wiring connections correct? Reviewpage 16.InstallationStep 6,3. The door operates from the Door Control, but not fromthe remote control:Is the door push button flashing?Program the opener to match the remote control code.(Refer to instructions on the motor unit panel.) Repeat withall remotes.4. The remote control has short range:Change the location of the remote control in your car.Check to be sure the antenna on the side or back panel ofmotor unit extends fully downward.Some installations may have shorter range due to a metaldoor, foil backed insulation, or metal garage siding.5. The garage door opens and closes by itself:Be sure that all remote control push buttons are off.Remove the bell wire from the door control terminals andoperate from the remote only. If this solves the problem, thedoor control is faulty (replace), or there is an intermittent shorton the wire between the door control and the motor unit.Clear memory and re-program all remote controls.6. The door doesn't open completely:Is something obstructing the door? Is it out of balance, orare the springs broken? Remove the obstruction or repairthe door.If the door is in good working order but now doesn't openall the way, increase the up force. See 1Adjustment Step .If the door opens at least 5 feet, the travel limits may needto be increased. One turn equals 2 inches of travel. SeeAdjustment Step 1.Repeat the safety reverse test after the adjustment iscomplete.7. The door stops but doesn't close completely:Review the Adjustment Step1.Repeat the safety reverse test after any adjustment of doorarm length, close force or down limit.8. The door opens but won't close:If the opener light blinks, check the safety reversing sensor.See Installation Step 10.If the opener light doesn't blink and it is a new installation,check the down force.

If it is unbalancedor binding, call a trained door systems technician.Clear any ice or snow from the garage floor area wherethe door closes.Review Adjustment Step 1 on page 24.If door reverses in the fully closed position, see AdjustmentStep 1.Repeat safety reverse test after adjustments to force and travellimits. The need for occasional adjustment of the force andlimit settings is normal. Weather conditions in particular canaffect door travel.10. The door reverses for no apparent reason and openerlight blinks for 5 seconds after reversing:Check the safety reversing sensor. Remove any obstructionor align the receiving eye. See Installation Step 10.11, The opener light doesn't turn on:Replace the light bulb (75 watts maximum). Use a standardneck garage door opener bulb if regular bulb burns out.12. The opener strains or maximum force is needed tooperate door:The door may be out of balance or the springs may bebroken. Close the door and use the emergency releasehandle to disconnect the trolley. Open and close the doormanually. A properly balanced door will stay in any point oftravel while being supported entirely by its springs. If itdoes not, disconnect the opener and call a trained doorsystems technician. Do not increase the force to operatethe opener.13. The opener motor hums briefly, then won't work:The garage door springs may be broken. See above.If the problem occurs on the first operation of the opener,door may be locked. Disable the door lock. If the chain wasremoved and reinstalled, the motor may be out of phase.Remove the chain; cycle the motor to the down position.Observe the drive sprocket. When it turns in a clockwisedirection and stops in the down position, reinstall the chain.Repeat the safety reverse test after the adjustment iscomplete.14. The opener won't operate due to power failure:Use the emergency release handle to disconnect thetrolley. The door can be opened and closed manually.When power is restored, press the Door Control pushbutton and trolley will automatically reconnect (unlesstrolley is in lockout position.) See page 24.The Emergency Key Release accessory (for use ongarages with no service door) disconnects the trolley fromoutside the garage in case of power failure.15.
