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.
Immediately after the gate has started moving, it
stops and reverses.
Obstacle in area of gate.
Check gate area for objects
check wiring of motor (LYN/SCS)
The gate opener does not open the gate fully.
1. Are the post dimensions A+B correct?
2. Has the travel of the controller been set
correctly?
1. Check A+B dimensions.
2. Reprogram if required
Gate can only be opened
1.photocell blocks
1.Function and connection must be
checked
“Timer to close” doesn’t work.
1. Only works if the 2-cable photocell
770E(ML) or 771E(ML) has been
installed.
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.
1.A safety photocell, a contact strip or the
stop disables the control board
2.Only one photocell was connected for
OPEN
Check diagnostic LED
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. Motor terminal possibly not connected
properly.
1. Programming remote control.
2. Find and rectify fault(s) (see description of
diagnostic LEDs).
3. Check photocell connection / programming.
4. Check terminals and connections.
Control board does not work with transmitter
1. transmitter not programmed
2. A photocell blocked
1.Program transmitter
2.Check photocells, check diagnostic LEDs
3. Jumper “RADIO” must be plugged.
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.
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 gate post is so thick that I am unable to
comply with the requisite A+B dimensions.
Reduce post thickness or shift gate location.
FAQs
Pressing P1, P2 and P3 does not show any reaction
Jumper “RADIO” must be removed
Check whether the radio module is
seated correctly.
Travel distance can’t be programmed.
1. Jumper setting not correct
2. Motor wiring not correct or cable broken
3. Diagnostic LED
4. Electric noise in wiring disturbs
5. Gate moves for 1 second only and stops
without reversal during programming
6. ART only: Passpoint adjustment incorrect
7. ART only: Motor disengaged
1. Check manual, especially “1/2 Motor”
2. If motor is moving check brown,
green, white, yellow cable. Test with
different cable to exclude that the
defect is the cable in the ground.
Or connect for testing the motor
direct to the control board without
extension cable.
3. Check diagnostic for route cause.
4. Refer to solution 2 and if applicable
change wiring type or routing. Verify
wiring with manual recommendation.
5. Not enough electrical power (volts) or
bad wiring. Refer to solution 2.
6. Adjust passpoint cams in motor.
Refer to ART manual.
7. Engage motor. Refer to ART manual.
The operator sometimes movess slowly
Powerfailure
Common procedure. After powerfailure the
operator performs a selftest. Depending on
the operator model this can take a few
seconds or a complete cycle (SUB). Do not
interrupt this test via remote control or switch,
otherwise the limits may change. If this is the
case reprogram travel distance using P1.
