INSTALLATION STEP 10Install The Protector System®

The safety reversing sensor must be connectedand aligned correctly before the garage dooropener will move in the down direction.

IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSORWhen properly connected and aligned, the sensorwill detect an obstacle in the path of its electronicbeam. The sending eye (with an orange 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 more 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.

If it is necessary to mount the units on the wall, thebrackets must be securely fastened to a solidsurface such as the wall framing. Extension brackets(see accessories) are available if needed. Ifinstalling in masonry construction, add a piece ofwood at each location to avoid drilling extra holes inmasonry if repositioning 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.

• Be 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 reversing

sensor. This required safety device MUST NOT bedisabled.

– Install the safety reversing sensor so beam is NOHIGHER than 6" above garage floor.

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 of

each door track, with the curved arms facing thedoor. Snap into place against the side of the track.It should lie flush, with the lip hugging the backedge of the track, as shown in Figure 1.

If your door track will not support the bracketsecurely, wall installation is recommended.

Wall installation: • Place the bracket against the wall with curved

arms facing the door. Be sure there is enoughclearance for the sensor beam to be unobstructed.

• If additional depth is needed, an extension bracket(see Accessories) or wood blocks can be used.

• Use bracket mounting holes as a template tolocate and drill (2) 3/16" diameter pilot holes onthe wall at each side of the door, no higher than 6"above the floor.

• Attach brackets to wall with lag screws(not provided).

• If using extension brackets or wood blocks, adjustright and left assemblies to the same distance outfrom the mounting surface. Make sure all doorhardware obstructions are cleared.

Floor installation: • Use wood blocks or extension brackets (see

Accessories) to elevate sensor brackets so thelenses will be no higher than 6" above the floor.

• Carefully measure and place right and leftassemblies at the same distance out from the wall.Be sure all door hardware obstructions arecleared.

• Fasten to the floor with concrete anchors asshown.

INSTALLATION STEP 11Fasten the Door Bracket

Follow instructions which apply to your door type asillustrated below or on the following page.

A horizontal reinforcement brace should be longenough to be secured to two or three verticalsupports. A vertical reinforcement brace shouldcover the height of the top panel. Figure 1 shows one piece of angle iron as thehorizontal brace. For the vertical brace, 2 pieces ofangle iron are used to create a U-shaped support.The best solution is to check with your garage doormanufacturer for an opener installation doorreinforcement kit.

NOTE: Many door reinforcement kits provide fordirect attachment of the clevis pin and door arm. Inthis case you will not need the door bracket; proceedto Step 12.

SECTIONAL DOORS1. Center the door bracket on the previously marked

vertical centerline used for the header bracketinstallation. Note correct UP placement, asstamped inside the bracket.

2. Position the top edge of the bracket 2"-4" belowthe top edge of the door, OR directly below anystructural support across the top of the door.

3. Mark, drill holes and install as follows, dependingon your door’s construction:

Metal or light weight doors using a vertical angleiron brace between the door panel support andthe door bracket: • Drill 3/16" fastening holes. Secure the door bracket

using the two 1/4"-14x5/8" self-threading screws.(Figure 2A)

• Alternately, use two 5/16" bolts, lock washers andnuts (not provided). (Figure 2B)

Metal, insulated or light weight factory reinforceddoors: • Drill 3/16" fastening holes. Secure the door bracket

using the self-threading screws (Figure 3).

Wood Doors:• Use top and bottom or side to side door bracket

holes. Drill 5/16" holes through the door andsecure bracket with 5/16"x2" carriage bolts, lockwashers and nuts (not provided). (Figure 4)

NOTE: The 1/4"-14x5/8"self-threading screws arenot intended for use onwood doors.

To prevent damage to garage door, reinforce inside ofdoor with angle iron both vertically and horizontally.

- Manually close the door and lift the door arm tothe trolley. The arm should touch the trolley justahead of the door arm connector hole. Refer tothe fully closed trolley/door arm positions in theillustration. If the arm is behind the connectorhole, adjust the limit further. One full turn equals2" of trolley travel.

3. Connect the door arm to the trolley:• Close the door and join the curved arm to the

connector hole in the trolley with the remainingclevis pin. It may be necessary to lift the doorslightly to make the connection.

• Secure with a ring fastener.

• Run the opener through a complete travel cycle.If the door has a slight “backward” slant in fullopen position as shown in the illustration,decrease the UP limit until the door is parallel tothe floor.

NOTE: When setting the up limit on the followingpage, the door should not have a “backward” slantwhen fully open as illustrated below. A slightbackward slant will cause unnecessary buckingand/or jerking operation as the door is being openedor closed from the fully open position.

28

ADJUSTMENT STEP 1Adjust the UP and DOWN TravelLimits

Limit adjustment settings regulate the points at whichthe door will stop when moving up or down.

To operate the opener, press the Door Control pushbar. Run the opener through a complete travel cycle.

• Does the door open and close completely?

• Does the door stay closed and not reverseunintentionally when fully closed?

If your door passes both of these tests, no limitadjustments are necessary unless the reversing testfails (Adjustment Step 3).

Adjustment procedures are outlined below. Read theprocedures carefully before proceeding toAdjustment Step 2. Use a screwdriver to make limitadjustments. Run the opener through a completetravel cycle after each adjustment. NOTE: Repeated operation of the opener duringadjustment procedures may cause the motor tooverheat and shut off. Simply wait 15 minutes andtry again.

NOTE: If anything interferes with the door’s upwardtravel, it will stop. If anything interferes with thedoor’s downward travel (including binding orunbalanced doors), it will reverse.

HOW AND WHEN TO ADJUST THE LIMITS

• If the door does not open completely but opensat least five feet:Increase up travel. Turn the UP limit adjustmentscrew clockwise. One turn equals 2" of travel.

NOTE: To prevent the trolley from hitting the coverprotection bolt, keep a minimum distance of 2-4"between the trolley and the bolt.

• If door does not open at least 5 feet: Adjust the UP (open) force as explained inAdjustment Step 2.

• If the door does not close completely:Increase down travel. Turn the down limitadjustment screw counterclockwise. One turnequals 2" of travel.

If door still won't close completely and the trolleybumps into the pulley bracket (see page 4), trylengthening the door arm (page 26) anddecreasing the down limit.

• If the opener reverses in fully closed position:Decrease down travel. Turn the down limitadjustment screw clockwise. One turn equals 2"of travel.

Without a properly installed safety reversal system,persons (particularly small children) could beSERIOUSLY INJURED or KILLED by a closing garagedoor.• Incorrect adjustment of garage door travel limits will

interfere with proper operation of safety reversalsystem.

• If one control (force or travel limits) is adjusted, theother control may also need adjustment.

• After ANY adjustments are made, the safety reversalsystem MUST be tested. Door MUST reverse oncontact with one-inch high object (or 2x4 laid flat) onfloor.

• If the door reverses when closing and there isno visible interference to travel cycle:If the opener lights are flashing, the SafetyReversing Sensors are either not installed,misaligned, or obstructed. See Troubleshooting,page 23.

Test the door for binding: Pull the emergencyrelease handle. Manually open and close the door.If the door is binding or unbalanced, call for atrained door systems technician. If the door isbalanced and not binding, adjust the DOWN(close) force. See Adjustment Step 2.

ADJUSTMENT STEP 2Adjust the Force

Force adjustment controls are located on the rightpanel of the motor unit. Force adjustment settingsregulate the amount of power required to open andclose the door.

If the forces are set too light, door travel may beinterrupted by nuisance reversals in the downdirection and stops in the up direction. Weatherconditions can affect the door movement, sooccasional adjustment may be needed.

The maximum force adjustment range is about3/4 of a complete turn. Do not force controlsbeyond that point. Turn force adjustment controlswith a screwdriver.

NOTE: If anything interferes with the door’s upwardtravel, it will stop. If anything interferes with thedoor’s downward travel (including binding orunbalanced doors), it will reverse.

HOW AND WHEN TO ADJUST THE FORCES1. Test the DOWN (close) force

• Grasp the door bottom when the door is abouthalfway through DOWN (close) travel. The doorshould reverse. Reversal halfway through downtravel does not guarantee reversal on a one-inchobstruction. See Adjustment Step 3.If the door is hard to hold or doesn't reverse,DECREASE the DOWN (close) force by turningthe control counterclockwise. Make smalladjustments until the door reverses normally.After each adjustment, run the opener through acomplete cycle.

• If the door reverses during the down (close)cycle and the opener lights aren't flashing,INCREASE DOWN (close) force by turning thecontrol clockwise. Make small adjustments untilthe door completes a close cycle. After eachadjustment, run the opener through a completetravel cycle. Do not increase the force beyondthe minimum amount required to close the door.

2. Test the UP (open) force• Grasp the door bottom when the door is about

halfway through UP (open) travel. The doorshould stop. If the door is hard to hold ordoesn't stop, DECREASE UP (open) force byturning the control counterclockwise. Make smalladjustments until the door stops easily andopens fully. After each adjustment, run theopener through a complete travel cycle.

• If the door doesn’t open at least 5 feet,INCREASE UP (open) force by turning thecontrol clockwise. Make small adjustments untildoor opens completely. Readjust the UP limit ifnecessary. After each adjustment, run theopener through a complete travel cycle.
