1.Is the door travel programmed
correctly?
2.Is the force adjusted correctly?
1. Program door travel again
2. Increase force (under wind load the
operator may run a bit slower)
(Remote controlled) universal receiver does not work
Observe polarity (terminals 14/15)
Swap “+” and “-” cables
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.
