Frequently asked questions
How long does it take to install a gate opener?
What happens in case of power failure?
Is it possible to open wing for pedestrian mode?
Gate opener does not function / does not
respond when button is pressed.
Immediately after the gate has started moving, it
stops and reverses.
Gate can only be opened
"Timer to close" doesn't work.
The gate opener hums slightly but has no force
The gate opener doesn't respond at all, although
the controller has been connected (LEDs are on).
The unit does not close automatically, it
OPENS automatically
Control board does not work with transmitter
The control board is not running
Universal receiver does not work
The wing does not open completely.
The force setting has been altered, but no
difference is apparent.
The remote control's range is too short.
The gate must follow a slope.
Depending on your specific technical skills, the installation of the mechanical components can
take approx. 3 to 8 hours. Firstly, the gate needs to be properly prepared such that installation
work can commence. The electrical connection work takes approx. 1 to 2 hours. Each user
should be instructed for at least 30 minutes with regard to the operation of the gate opener,
whereby its functionality should be demonstrated and safety aspects, protective facilities and
procedure in case of power failure should all be explained.
All Chamberlain gate openers are equipped with a release system by means of which the gate
can be operated manually in case of power failure.
Yes, it is possible. This process can be operated via remote control (a 2-channel remote
control is the minimum requirement here) or via switch operation.
1. Connection to button is loose.
2. STOP switch connection is loose; STOP
LED is off.
3. Obstacle is blocking photocell in direction
of movement.
4. Safety edge is damaged or has
encountered an obstacle.
5. Gate opener is still released.
Obstacle in area of gate.
1.Photocell blocks
2.Dip switch setting not as desired
1. Only works if the 2-cable photocell 770E(ML) or 771E(ML) has been installed.
2. Then turn "timer to close" potentiometer in a clockwise direction.
1. Capacitor is not correctly connected to the
brown and black cable.
2. Force has not been set.
3. The gate opener has been released.
1. Remote control has not been programmed.
2. LEDs indicate a fault.
3. Photocell connected incorrectly.
4. Jumper between STOP and COM missing.
5. Motor terminal possibly not connected
properly.
Check setting of limitswitch
1. Transmitter not programmed
2. A photocell blocks
No covered distance learned
Observe polarity
1.Is the gate travel programmed
correctly?
2.Is the force adjusted correctly?
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.
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.
