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)
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
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 unit does not close automatically, it
OPENS automatically
The motor cables are not connected correctly
The motor cables (brown,black) must be
swapped
Control board does not work with transmitter
1.transmitter not programmed
2.An photocell blocks
1.Program transmitter
2.Check photocells
Gate can only be opened
1.photocell blocks
2.Dip switch setting not as desired
1.Function and connection must be
checked
2.Check dip switch
The control board is not running
No covered distance learned

See Initial operation
The wings do not open completely.
1.Insufficient force in the event of high
wind loads
(entire gates)
2.Gate sluggish/heavy
1.Reset force ( increase )
2.Improve ease of movement
3.Program control board again
(Remote controlled) universal receiver does not work
Observe polarity (terminals 15/16)
Swap “+” and “-” cables
The gate opener is so strong that it bends the
gate and/or post.
1. A+B dimensions correct?
2. Force set too high?
3. Reinforce gate?
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
Can different A+B dimensions be used on the two
sides?
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).
The gate must follow a slope.
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.
The force setting has been altered, but no
difference is apparent.
Disconnect the controller from the power supply for a few seconds in order to activate the
control board’s self-diagnosis functionality.
The remote control’s range is too short.
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.
The gate post is so thick that I am unable to
comply with the requisite A+B dimensions.
Reduce post thickness or shift gate location.
