INSTALLATION STEP 9

Install The Protector System

The safety reversing sensor must be connected and aligned correctly before the garage door opener will move in the down direction. This is a required safety device and cannot be disabled.

IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSOR

When properly connected and aligned, the safety reversing sensor will detect an obstacle in the path of its electronic beam. The sending eye (with an amber indicator light) transmits an invisible light beam to the receiving eye (with a green indicator light). If an obstruction breaks the light beam while the door is closing, the door will stop and reverse to full open position, and the opener lights will flash 10 times.

The units must be installed inside the garage so that the sending and receiving eyes face each other across the door, no more than 6" (15 cm) above the floor. Either can be installed on the left or right of the door as long as the sun never shines directly into the receiving eye lens.

The mounting brackets are designed to clip onto the track of sectional garage doors without additional hardware.

Facing the door from inside the garage

Be sure power is not connected to the garage door opener BEFORE installing the safety reversing sensor.

To prevent SERIOUS INJURY or DEATH from a closing garage door:

• Correctly connect and align the safety reversing sensor. This required safety device MUST NOT be disabled.

• Install the safety reversing sensor so beam is NO HIGHER than 6" (15 cm) above garage floor.

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

The invisible light beam path must be unobstructed. No part of the garage door (door tracks, springs, hinges, rollers or other hardware) may interrupt the beam while the door is closing.

INSTALLING THE BRACKETS Be sure power to the opener is disconnected. Install

and align the brackets so the safety reversing sensors will face each other across the garage door, with the beam no higher than 6" (15 cm) above the floor. They may be installed in one of three ways,as follows.

Garage door track installation (preferred) (Figure 1):

• Slip the curved arms over the rounded edge of each door track, with the curved arms facing the door. Snap into place against the side of the track. It should lie flush, with the lip hugging the back edge of the track, as shown in Figure 1.

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

Wall installation (Figure 2 and 3):

• Place the bracket against the wall with curved arms facing the door. Be sure there is enough clearance 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 to locate and drill (2) 3/16" diameter pilot holes on the wall at each side of the door, no higher than 6" (15 cm) above the floor.

• Attach brackets to wall with lag screws (Not Provided).

• If using extension brackets or wood blocks, adjust right and left assemblies to the same distance out from the mounting surface. Make sure all door hardware obstructions are cleared.

Floor installation (Figure 4):

• Use wood blocks or extension brackets (See Accessories) to elevate sensor brackets so the lenses will be no higher than 6" (15 cm) above the floor.

• Carefully measure and place right and left assemblies at the same distance out from the wall. Be sure all door hardware obstructions are cleared.

• Fasten to the floor with concrete anchors as shown.

ADJUSTMENT STEP 1

Program the Travel Limits

Travel limits regulate the points at which the door will stop when moving up or down. Follow the steps below to set the limits.

Figure 1

Purple Button

Indicator Light

Black Button

Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.

• NEVER learn forces or limits when door is binding or sticking. Repair door first.

• Incorrect adjustment of garage door travel limits will interfere with proper operation of safety reversal system.

• After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2" high (3.8 cm) object (or 2x4 laid flat) on floor.

To program the travel limits:

Adjust the position of the door by using the black and purple buttons. Black moves the door UP (open) and purple moves the door DOWN (close).

1. Setting the UP position: Press and hold the black

button until the yellow indicator light starts flashing slowly then release.

2. Push and hold the black button until the door reaches the desired UP (open) position (Figure 2).

NOTE: Check to be sure the door opens high enough for your vehicle.

3. Push the remote control or door control (Figure 3). This sets the UP (open) limit and begins closing the door.

NOTE: Excessive movement of the motor unit will cause premature wear. See Troubleshooting section.

4. Immediately when the door begins to move down, press and release either the black or purple button. This will stop the door.

5. Setting the DOWN position: Push and hold the purple button until the door reaches the desired DOWN (closed) position (Figure 4).

6. Once the door is closed, if there appears to have too much pressure on the door, you may toggle the door back and forth using the black and purple buttons to reach the desired closed position.

7. Push the remote control or the door control (Figure 3). This sets the DOWN (close) limit and should bring the door to the open position.

• If the opener is not stopping exactly where you would like it, repeat steps 1 through 8 and program the limits again.

• When the unit stops in both the desired up (open) and down (close) positions, proceed to

Adjustment Steps 2, Setting the Force.

To prevent damage to vehicles, be sure fully open door provides adequate clearance.

ADJUSTMENT STEP 2

Setting the Force

The force setting button is located on the front panel. The force setting measures the amount of force required to open and close the door.

1. Locate the purple button on the unit (Figure 1).

2. Push the purple button twice to enter unit into Force Adjustment Mode (Figure 2). The LED (Indicator Light) will flash quickly.

3. Push the remote control or control console (Figure 3). The door will travel to the DOWN (close) position. Push the remote control or control console again, the door will travel to the UP (open) position. Push the remote control or control console a third time to send the door to the DOWN (close) position.

The LED (Indicator Light) will stop flashing when the force has been learned.

The unit has learned the forces required to open and close your door.

The door must travel through a complete cycle, UP and DOWN, in order for the force to be set properly. If the unit cannot open and close your door fully, inspect your door to insure that it is balanced properly and is not sticking or binding. See page 4, “Preparing your

garage door.”

Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.

• NEVER learn forces or limits when door is binding or sticking. Repair door first

• Too much force on garage door will interfere with proper operation of safety reversal system.

• After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2" high (3.8 cm) object (or 2x4 laid flat) on floor.

ADJUSTMENT STEP 3

Test the Safety Reversal System

TEST

• With the door fully open, place a 1-1/2" (3.8 cm) board (or a 2x4 laid flat) on the floor, centered under the garage door.

• Operate the door in the down direction. The door must reverse on striking the obstruction. Upon successful safety reversal test proceed to Adjustment Step 4.

ADJUST

• If the door stops on the obstruction, it is not traveling far enough in the down direction. Complete Adjustment Steps 1 and 2 Programming the Limits and Forces.

• Repeat the test.

• When the door reverses on the 1-1/2" (3.8 cm) board (or 2x4 laid flat), remove the obstruction and run the opener through 3 or 4 complete travel cycles to test adjustment.

• If the unit continues to fail the Safety Reverse Test, call for a trained door systems technician.

IMPORTANT SAFETY CHECK:

Test the Safety Reverse System after:

• Each adjustment of limits, or force controls.

• Any repair to or adjustment of the garage door (including springs and hardware).

• Any repair to or buckling of the garage floor.

• Any repair to or adjustment of the opener.

ADJUSTMENT STEP 4

Test The Protector System

• Press the remote control push button to open the door.

• Place the opener carton in the path of the door.

• Press the remote control push button to close the door. The door will not move more than an inch, and the opener lights will flash.

The garage door opener will not close from a remote if the indicator light in either sensor is off (alerting you to the fact that the sensor is misaligned or obstructed).

If the opener closes the door when the safety reversing sensor is obstructed, do not operate the door. Call for a trained door systems technician.

Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.

• Safety reversal system MUST be tested every month.

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

• After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2" (3.8 cm) high object (or 2x4 laid flat) on the floor.

ADJUSTMENT STEP 5

Test Cable Tension Monitor

If your cable tension monitor has been activated the LED will blink 9 times.

ADJUSTMENT STEP 6

Test Power Door Lock

TEST

• With the door fully closed, the power door lock bolt should be protruding through the track.

• Operate the door in the open direction. The power door lock should retract before the door begins to move.

• Operate the door in the down direction. When the door reaches the fully closed position, the power door lock should automatically activate to secure the door.

NOTE: If the power door lock does not function, the lock can be manually released by sliding the manual release handle to the open position.

ADJUSTMENT STEP 7

To Open the Door Manually

Disengage door lock before proceeding. The door should be fully closed if possible. Pull down on the emergency release handle and lift the door manually. To reconnect the door to the opener, pull down the emergency release handle straight down a second time. The door will reconnect on the next UP or DOWN operation.

Test the emergency release:

• Make sure the garage door is closed.

• Pull the emergency release handle. The garage door should then be able to be opened manually.

• Return the door to the closed position.

• Pull the emergency handle a second time.

• Reconnect the door to the opener.

To prevent possible SERIOUS INJURY or DEATH from a falling garage door:

• NEVER use emergency release handle unless garage doorway is clear of persons and obstructions.
