After opener has been installed and adjusted, The Protector System™ accessory ca n be i nstalled.

Instructions are included with this accessory.

The Protector System™ provides an additional measure of safety against a small child being caught under a garage door. It uses an infra-red

beam which, when broken by an obstruction, causes a closing door to open and prevents an open door from closing an d is

strongly recommended for home-

owners with young children. Note: The opener will automatically detect the

protector system when it is installed and operating for 5 minutes (during this time the beams must remain unobstructed). The opener will not close unless the sensors are aligned.

Page 9

CARE OF YOUR OPENER

When properly installed, your opener will provide high performance with a minimum of maintenance. The opener does not require additional lubrication. Limit and Force Settings: These settings must be checked and properly set when the opener is installed. Weather conditions may cause some minor changes in the door operation, requiring some re-adjustments, particularly during the first year of operation. Refer to limit and force setting in, sections 11 & 12, pages 6 & 7. Follow the instructions carefully and repeat the safety reverse test after any adjustment.

Remote Control: Additional remotes can be purchased at any time. Refer to Accessories. Any new remotes must be programmed into the opener. Remote Control Battery: The lithium batteries should produce power for up to 5 years. If transmission range decreases, replace the battery.

Troubleshooting

1. The opener doesn't operate from either the GREEN start button or the remote controls:

• Does the opener have electric power? Plug a lamp

intothe outlet. If it doesn't light, check the fuse box.

• Have you disabled all door locks? Review installation

instruction warnings on page 1.

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

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

• The garage door spring may be broken. Have it

replaced.

2. Opener operates from the remote control, but

not from the wired wall control (optional accessory):

• Is the wall control lit? If not, reverse the two wires. If

the opener runs, check for a faulty wire connection at the wall control, a short under the staples, or a broken wire.

• Are the wiring connections correct? Refer to wired

wall control instructions.

3. The door operates from the GREEN start button

or wired wall control, but not from the wireless wall control or remote control:

• If the wired wall control is installed and it is flashing,

ensure the Lock feature is off.

• Program the opener to match the remote control

code. (Refer to section 10, page 6.) Repeat with all 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 bottom of the

opener extends fully downward.

• Some installations may have shorter range due to a

metal door, 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.

• If the wired wall control (optional accessory) is

installed, remove the bell wire from the wired wall control terminals and operate from the GREEN star button or remote control. If this solves the problem, the wired wall control is faulty (replace), or there is an intermittent short on the wire between the wired wall control and the opener.

• Clear memory and re-program all wireless wall

controls and remote controls.

6. The door reverses and stops before opening completely:

• 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 reverses for no apparent reason and opener lights blink for 5 seconds after reversing:

• Check the Protector System (safety beams), if

installed. Correct alignment if the red light on the beam is solid.

8. The door opens but won't close or reverses while closing:

• Is something obstructing the door? Pull the manual

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 garage floor area where the door closes.• Repeat the limit and force setting in section 11 & 12, pages 6 & 7. Repeat safety reverse test after adjustments.

9. 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 manual release 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.

10. The opener motor hums briefly, then won't

work:

• Check that the door is not in manual release mode, refer section 8, page 5.

• 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 any door locks.

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

• Use the manual release handle to disconnect the door. The door can be opened and closed manually. When power is restored, re-engage the opener, refer section 8, page 5.

• If a Standby power unit is connected, the opener should be able to operate up to 20 times without power.

12. Setting the limits manually:

a. Check that the opener position jumper is correct, refer section 5, page 3. b. Press and hold the BLACK button until the orange indicator light starts flashing slowly then release. c. Press the BLACK button to move the door UP or the PURPLE button to move the door DOWN until the door reaches the desired UP limit. Ensuring there is enough clearance for your vehicle. d. Press the GREEN start button. This sets the UP limit and begins closing the door. Immediately press either the PURPLE or the BLACK button. The door will stop. Adjust the desired DOWN limit using the BLACK and the PURPLE buttons. Check to be sure the door is fully closed without applying excessive pressure to the door curtain. Press the GREEN start button. This sets the DOWN limit and begins opening the door. NOTE: If neither the BLACK or the PURPLE button is pressed, the door will reverse off the floor and the DOWN travel limit will be set automatically. e. Open and close the door with the GREEN start button, remote control or wall control 2 or 3 times.

• If the door does not stop in the desired UP limit or

reverses before the door stops at the DOWN limit. Proceed to Setting the Force, section 12, page 7. If the door still does not stop at the desired limits is something obstructing the door? Disengage the opener. Open and close the door manually. If it is unbalanced or binding, call a trained door systems technician.

• If the door stops at both the desired UP and DOWN

limits, proceed to Setting the Force.

13. Auto close does not work:

•Check alignment of beams (LED indicators should be

solid). If setting up see section 15 page 8. To re-set auto detect of the safety beams, turn the power off, (remove standby power unit if installed) and set timer trim pot to zero before re-setting power.
