Chamberlain ML5500 Garage Door Opener User Manual


 
PROGRAM YOUR OPENER & REMOTE
Activate the opener only when door is in full view, free of obstruction
and properly adjusted. No one should enter or leave garage while
door is in motion. Do not allow children to operate push button(s) or
remote(s). Do not allow children to play near the door.
Your garage door opener receiver and remote control transmitter are set to
a matching code. If you purchase additional remote controls, the garage
door opener must be programmed to accept the new remote code.
Program the Receiver to Match Additional Remote Control Codes
1. Press and hold the remote control push button (1).
2. Press and release the "Smart" button (2) on the back panel of the
opener. The opener light will flash once.
3. Release the remote push button.
Now the opener will operate when the remote control push button is
pressed.
If you release the remote control push button before the opener lights
flash, the opener will not accept the code.
To Erase all Remote Control Codes
Press and hold the "Smart" button on the opener panel until the indicator
light turns off (about 6 seconds). All the codes the opener has learned
will be erased.
To reprogram, repeat Steps 1 3 for each remote control in use.
ADJUSTMENT SECTION
-
LIMIT ADJUSTMENT
Run the opener through a complete travel cycle. Limit adjustments are
not necessary when the door opens and closes completely and doesn't
reverse unintentionally in the fully closed position.
Situations requiring limit adjustment are listed below. Run the opener
through a complete travel cycle after each adjustment.
NOTE: Repeated operation of the opener during adjustment procedures
may cause motor to overheat and shut off. Allow a 15 minute cooling
period after 5 continuous operations of the opener.
Read the following carefully before proceeding to Force Adjustment. Use a
screwdriver to make limit adjustments.
If Door Doesn't Open Completely but Opens at Least 1,5m (5 feet):
Increase up travel. Turn the up limit adjustment screw (1) clockwise. One
turn equals 5cm (2") of travel.
If door does not open at least 1,5m (5 feet): Adjust up (open) force.
See Force Adjustment.
If Door Doesn't Close Completely: Increase down travel. Turn down
limit adjustment screw (2) counterclockwise. One turn equals 5cm (2") of
travel. If the door still will not close completely, lengthen the door arm. If it
still will not close completely, lower the header bracket.
If Opener Reverses in Fully Closed Position: Decrease down travel.
Turn down limit adjustment screw (2) clockwise. One turn equals 5cm (2")
of travel.
If Door Reverses when Closing and there is no Interference to Travel
Cycle: Test door for binding. Pull manual release handle. Manually open
and close door. If door is binding, call a door serviceman. If door is not
binding or unbalanced, adjust down (close) force.
FORCE ADJUSTMENT
The force, as measured on the closing edge of the door, should not
exceed 150 N (15kg). If the closing force is adjusted to more than
150 N, the Protector System must be installed.
Do not use force adjustments to compensate for a binding or sticking
garage door. Excessive force will interfere with proper operation of
safety reverse system or damage garage door.
Force Adjustment Controls (1 & 2) are located on the back panel of the
opener.
If the force adjustments are set too light, door travel may be interrupted by
nuisance reversals in down direction and stops in up direction. Weather
conditions can affect the door movement, occasional adjustment may be
needed.
Maximum force adjustment range is 260 degrees, about 3/4 of a complete
turn. Do not force controls beyond that point. Turn force adjustment
controls with a screwdriver.
Test Down (Close) Force: Grasp the door handle or door bottom when
door is about halfway through down (close) travel. Door should reverse.
Reversal halfway through down travel does not guarantee reversal on a
50mm (2") obstruction. If the door is hard to hold or doesn't reverse,
decrease down (close) force by turning the control (2) in a
counterclockwise direction. Make small adjustments until door reverses
normally. After each adjustment, run opener through a complete cycle.
If Door Doesn't Open at Least 1,5m (5 feet): Increase up (open) force by
turning the control (1) in a clockwise direction. Make small adjustments
until door opens completely. Re-adjust up limit if necessary. After each
adjustment, run opener through a complete travel cycle.
If Door Reverses During Down (Close) Cycle: Increase down (close)
force by turning the control (2) in a clockwise direction. Make small
adjustments until door completes close cycle. After each adjustment, run
the opener through a complete travel cycle. Do not increase the force
beyond the minimum amount required to close the door.
TEST THE SAFETY REVERSE SYSTEM
The safety reverse system test is important. Garage door must
reverse on contact with a 50mm (2") obstacle laid flat on the floor.
Failure to properly adjust opener may result in serious personal injury
from a closing garage door. Repeat test once a month and adjust as
needed.
Procedure: Always begin with door in fully open position. Place a 50mm
(2") obstacle (1) laid flat on the floor under the garage door. Operate the
door in the down direction. The door must reverse on the obstruction. If
the door stops on the obstruction, it is not traveling far enough in the
down direction. Increase the down limit by turning down limit adjustment
screw counterclockwise 1/4 turn. Repeat test.
When the door reverses on the 50mm (2") obstacle, remove the
obstruction and run the opener through a complete travel cycle. Door must
not reverse in closed position. If it does, adjust Limits and Force and
repeat safety reverse test.
INSTALL THE PROTECTOR
(See accessories)
The force, as measured on the closing edge of the door, should not
exceed 150 N (15kg). If the closing force is adjusted to more than
150 N, the Protector System must be installed.
After opener has been installed and adjusted, The Protector System™
accessory can be installed. 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 invisible beam which, when broken by an obstruction, causes a
closing door to open and prevents an open door from closing. It is strongly
recommended for homeowners with young children.
