FAQs
The gate opener doesn't respond at all; no LED is
on.
Immediately after the gate has started moving, it
stops and reverses.
The gate opener does not open the gate fully.
Gate can only be opened
"Timer to close" doesn't work.
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.
The gate opener doesn't respond at all, although
the controller has been connected (LEDs are on).
Control board does not work with transmitter
The control board is not running
The wings do not open completely.
The remote control's range is too short.
The gate must follow a slope.
The gate post is so thick that I am unable to
comply with the requisite A+B dimensions.
Possibly power failure.
Obstacle in area of gate.
1. Are the post dimensions A+B correct?
2. Has the travel of the controller been set
correctly?
1.photocell blocks
A safety photocell, a contact strip or the stop
disables the control board
Only one photocell was connected for OPEN
1. Remote control has not been programmed.
2. LEDs indicate a fault.
3. Photocell connected incorrectly.
4. Motor terminal possibly not connected
properly.
1.transmitter not programmed
2.An photocell blocks
No travel has been learned
1.Insufficient force in the event of high
wind loads (entire gates)
2.Gate sluggish/heavy
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-1LM.
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.
Reduce post thickness or shift gate location.
1. Check conductor and zero conductor.
2. Check house fusing.
Check area of gate for objects
If there is no obstacle, make another initial
operation to ensure the force will be learned
again.
1. Check A+B dimensions.
2. Reprogram if required
1.Function and connection must be
checked
1. Only works if the 2-cable photocell
770E(ML) or 771E(ML) has been
installed.
At least one photocell must be
connected and activated for CLOSED
or OPEN.
1. Programming remote control.
2. Find and rectify fault(s) (see description of
LEDs).
3. Check photocell connection / programming.
4. Check terminals and connections.
1.Program transmitter
2.Check photocells
Learn travel.
See Initial operation
1.Reset force ( increase )
2.Improve ease of movement
3.Program control board again
