• Read and follow all instructions carefully. The garage door opener is designed and tested to offer safe service provided it is installed and

•

operated in strict accordance with the instructions in this manual.

These safety alert symbols mean WARNING : A possible risk to personal safety or property damage exists.

Keep garage door balanced. Do not let the garage door

pener compensate for a binding or sticking garage door.

o Sticking, binding or unbalanced doors must be repaired before installing this opener.

Do not wear rings, watches or loose clothing while installing or servicing a garage door opener. Wear gloves, safety goggles and suitable protective clothing where appropriate.

Frequently examine the door installation, in particular cable, springs and mountings for signs of wear, damage or imbalance. Do not use if repair or adjustment is needed since springs and hardware are under extreme tension and a fault can cause serious personal injury.

To avoid serious personal injury from entanglement,

remove all ropes, chains and locks connected to the garage door before installing the door opener.

Installation and wiring must be in compliance with your

local building and electrical codes.

The safety reverse system test is very important. Your garage door MUST reverse on contact with a 40 mm obstacle placed on the floor. Failure to properly adjust the opener may result in serious personal injury from a closing garage door. Repeat the test once a month and make

any necessary adjustments.

This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

Use the Manual Release only for the seperation of the carriage from the drive and - if possible - ONLY with the door closed. Do not use the red handle to push the door up or pull it down. Operation of the emergency release can lead to uncontrolled movements of the door, if springs are weak or broken or if the door is unbalanced. Mount the release handle of the emergency release at a height less than 1.8 m from the floor.

The Protector SystemTMmust be used for all installations

here the closing force as measured on the bottom of the

w door is over 400 N (40 kgf). Excessive force will interfere with

the proper operation of the Safety Reverse System or damage the garage door.

TROUBLESHOOTING THE SAFETY REVERSING SENSORS

1. If the sending eye indicator LEDs are both flashing

after installation, check for:

• Electric power to the opener.

• A short in the white or white/black wires. These can occur at staples, or at opener connections.

• Incorrect wiring between safety reversing sensors and opener.

• A broken wire.

2. If the sending eye indicator light glows steadily but the receiving eye indicator light doesn't:

• Check alignment.

• Check for an open wire to the receiving eye.

3. If the receiving eye indicator light is dim, realign

either sensor.

NOTE: When the invisible beam path is obstructed or misaligned while the door is closing, the door will reverse. If the door is already open, it will not close and the LED indicator light will flash 10 times. See page 21.

Program the Travel Limits

Travel limits regulate the points at which the door will

top when moving up or down. Follow the steps below

s to set the limits.

Figure 1

To program the travel limits:

Adjust the position of the door by using the black and orange buttons. Black moves the door UP (open) and orange 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 to pass under.

3. Push the transmitter, wireless wall button or multi-function door control (Figure 3). This sets the UP (open) limit and begins closing the door.

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

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

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

6. Once the door is closed, check for proper pressure on the door (you should be able to manually push the door down 2mm). If there appears to be too much pressure on the door, you may toggle the door back and forth using the black and orange buttons to reach the desired position.

7. Push the transmitter, wireless wall button or the multi-function 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 7 and

program the limits again.

• When the unit stops in both the desired up

(open) and down (close) positions, proceed to

Adjustment Step 2, Setting the Force.

Without a properly installed safety reversal system, persons (particularly children) could be

ERIOUSLY INJURED or KILLED by a closing

S door.

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

• Incorrect adjustment of the 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 40mm high (1 1/2”) object on floor.

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

TROUBLESHOOTING

1. The opener doesn't operate from either the multifunction door control, wireless wall button or the transmitter:

• 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.)

• Have you disabled all door locks? Review installation

instruction warnings on page 7.

• Is there a build-up of ice or snow under the door? The

door may be frozen to the ground. Remove any restriction.

• The door spring may be broken. Have it replaced (see

page 5 for reference).

2. Opener operates from the transmitter, but not from the Wireless Wall Button:

• Check the LED on the Wireless Wall Button to ensure

the LED turns on when button is pushed. If the LED is weak or not on Change the batteries. (Remove cover and replace with CR2032 batteries X 2)

• If the LED turns on and is strong check to ensure the

unit is programmed into the unit (see page 19).

3. The door operates from the multi-function door control but not from the transmitter:

• Is the door push bar flashing? If so, Lock mode is

engaged. Make sure it is off by pressing the Lock button for two seconds.

• Program the opener to match the transmitter code.

(Refer to instructions on the opener panel.) Repeat with all Transmitter.

4. The transmitter has short range:

• Change the location of the transmitter in your car.

• Check to be sure the antenna on the side or back panel

of opener extends fully downward.

• Some installations may have shorter range due to a

metal door, foil backed insulation, or metal siding.

5. The door opens and closes by itself:

• Be sure that all transmitter push buttons are off.

• Remove the bell wire from the mulit-function door

control terminals and operate from the transmitter only. If this solves the problem, the multi-function door control is faulty (replace), or there is an intermittent short on the wire between the control console and the opener.

• Clear memory and re-program all transmitters.

6. The door doesn't open completely:

• Check powered door lock.

• Is something obstructing the door? Is it out of balance,

or are the springs broken? Remove the obstruction or repair the door.

7. The door opens but won't close:

• Check cable tension monitor (see installation step 4).

• If the opener LED is flashing, check the safety

reversing sensor. See Installation Step 8.

• If the opener LED is not flashing and it is a new

installation. See Adjustment Step 2. For an existing installation, see below.

Repeat the safety reverse test after the adjustment is complete.

8. The door reverses for no apparent reason and opener LED doesn’t flash:

Check cable tension monitor (see installation step 4).

•

• Is something obstructing the door? Pull the emergency release handle. Operate the door manually. If it is unbalanced or binding, call a trained door systems technician.

• Clear any ice or snow from the floor area where the door closes.

• Review Adjustment Step 2.

Repeat safety reverse test after adjustments.

9. The door reverses for no apparent reason and opener LED flashes for 5 seconds after reversing:

• Check the safety reversing sensor. Remove any obstruction or align the receiving eye. See Installation

Step 8.

10. The opener strains to operate door:

• The door may be out of balance or the springs may be broken. Close the door and use the emergency release handle to disconnect the door. Open and close the door manually. A properly balanced door will stay in any point of travel while being supported entirely by its springs. If it does not, disconnect the opener and call a trained door systems technician.

11.The opener motor hums briefly, then won't work:

• The door springs may be broken. See above.

• If the problem occurs on the first operation of the opener, door may be locked. Disable the powered door lock.

12.The opener won't operate due to power failure:

• Manually open the powered door lock.

• Use the emergency release handle to disconnect the door. The door can be opened and closed manually. When power is restored, pull manual release a second time.

• If an EverCharge Unit is connected, the opener should be able to operate up to 20 times without power.

13. Door loses limits.

• Collar not tightened securely. Tighten collar (see Assembly Steps 1 and 2) and reprogram limits (see Adjustment Step 1).

14. The opener moves when the door is in operation:

• Some minor movement is normal for this product. If it is excessive the collar will wear prematurely.

• Check to make sure the torsion bar is not moving left/right excessively.

• Check to make sure the torsion bar is not visibly moving up and down as it rotates.

• Check that the opener is mounted at a right angle to the jackshaft. If not, move the position of the mounting bracket.

15. Power lock makes noise when operating.

• Call your local Merlin

dealer or Chamberlain customer

service for replacement power lock.
