Battery Disposal - LiftMaster CB11 Manual De Instrucciones

The gate opener is so strong that it bends the
gate and/or post.
Can different A+B dimensions be used on the two
sides?
The gate must follow a slope.
The force setting has been altered, but no
difference is apparent.
The remote control's range is too short.
The gate post is so thick that I am unable to
comply with the requisite A+B dimensions.
The control board does not work any more using
the transmitter, only with the switch and even then
only as long as a button is pressed and kept
pressed.
Open with push-button (1) or CLOSE with push-
button (2)
The unit does not close automatically, it
OPENS automatically
Control board does not work with transmitter
Gate can only be opened
The control board is not running
The wings do not open completely.
(Remote controlled) universal receiver does not work Observe polarity (terminals 15/16)
DISPOSAL
The packaging is made from environmentally friendly materials. It can be disposed of in the local recycling bin. According to the European
Directive 2002/96/EC on waste electrical and electronic equipment, this device must be properly disposed of after use to ensure the reuse of
materials. The information on the possibilities of this waste disposal is provided by the local government or municipality.

BATTERY DISPOSAL

Batteries and rechargeable batteries may not be disposed along with domestic waste, but are
obliged to be returned.
After use they can be returned free of charge locally e.g. in trade or at municipal collecting points.
Batteries and rechargeable batteries are marked with a crossed waste container as well as with the
chemical symbol which describes their toxic element, "Cd" for cadmium, "Hg" for mercury and "Pb"
for lead.
1. A+B dimensions correct?
2. Force set too high?
3. Reinforce gate?
Generally speaking, yes, but the wings then open at different speeds. If the A+B dimensions
are altered significantly from the standard setting, the gate will run poorly and the fittings will
be subjected to greater stress (considerably reduced service life of installation).
Not recommended! Change gate! The gate can move in an uncontrolled (dangerous) manner
if the gate opener has been released. A stronger force is needed in the upwards direction of
the slope and then, in the opposite direction, the gate opener's force is too strong.
Disconnect the controller from the power supply for a few seconds in order to activate the
control board's self-diagnosis functionality.
The installation of an external aerial is recommended as the controller with the short cable
aerial is located either behind the post or near ground level in most cases. The optimum
location of the aerial is as high as possible in all cases. An appropriate aerial with installation
kit can be obtained from Chamberlain as an accessory with the product ref. no. ANT4X-
1EML.
1.Dip switch setting not as desired
2.A safety photocell, a contact strip or the
stop disables the control board
3.Only one photocell was connected for
OPEN
The motor cables are not connected correctly
1.transmitter not programmed
2.An photocell blocks
1.photocell blocks
2.Dip switch setting not as desired
No covered distance learned
1.Insufficient force in the event of high
wind loads
(entire gates)
2.Gate sluggish/heavy
1. Check A+B dimensions.
2. Turn force potentiometer in an
anticlockwise direction.
3. Possibly screw gate opener to a
reinforcement plate (post).
Possibly fit reinforcement plate at point
of pull / push pressure (gate wing).
Use suitable screws and plugs
Reduce post thickness or shift gate location.
1.Correction of the dip switch,
elimination of fault required. If the fault
cannot be repaired, it will be necessary
to "reset" and reprogram (see photocell)
2.At least one photocell must be
connected and activated for CLOSED
or OPEN & CLOSED.
The motor cables (brown,black) must be
swapped
1.Program transmitter
2.Check photocells
1.Function and connection must be
checked
2.Check dip switch
Learn covered distance.
See Initial operation
1.Reset force ( increase )
2.Improve ease of movement
3.Program control board again
Swap "+" and "-" cables
