Gate opener does not function / does not respond
when button is pressed.
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.
1. Check button and COM connections.
2. Check STOP switch connections
(STOP and COM).
3. Remove obstacle.
4. Remove obstacle and check
connections and wiring.
5. Lock gate opener.
The gate opener does not open the gate fully.
1. Are the post dimensions A+B correct?
2. Has the running time of the controller been
set correctly?
3. Has the force been set correctly?
1. Check A+B dimensions.
2. Reprogram as required – plus
approx. 3 seconds.
3. Correct force setting (gate opener
runs somewhat slower in windy
conditions).
The controller doesn’t respond when I alter the
Dip-switches.
Disconnect controller from power
supply, then alter Dip-switches.
“Timer to close” doesn’t work.
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.
The gate opener doesn’t respond at all; no LED is
on.
Possibly power failure.
1. Check conductor and zero conductor.
2. Check house fusing.
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
Immediately after the gate has started moving, it
stops and reverses.
Obstacle in area of gate.
Check area of gate for objects
The gate opener hums slightly but has no force
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. Check wiring of capacitor.
2. Turn force potentiometer in a clockwise
direction.
3. Lock gate opener.
The gate opener only works when I press and
hold the button on the remote control.
1. Controller in ‘hold to run’ operating mode.
2. A safety facility is not working correctly
(photocell, safety edge).
1. Disconnect controller from power supply,
then alter Dip-switches.
2. Observe LEDs; find and rectify fault.
The gate opener doesn’t respond at all, although
the controller has been connected (LEDs are on).
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.
1. Programming remote control.
2. Find and rectify fault(s) (see description of
LEDs).
3. Check photocell connection / programming.
4. Connect simple jumper.
5. Check terminals and connections.
The gate opener stops suddenly and then restarts
only after a lengthy pause.
If the gate is operated constantly, the motor
will reach its cut-off temperature - protective
facility - as the gate opener is not designed
for permanent operation.
Allow motor sufficient time to cool (min. 15
minutes).
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.
