1. Controller in ‘hold to run’ operating mode.
2. A safety facility is not working correctly

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

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).
How long is the probable service life of a gate opener?
When used for private purposes, a correctly installed gate opener can
operate perfectly for in excess of 10 years. Both the gate and the gate
opener must be checked regularly and serviced in accordance with
their respective instructions.
What happens in case of power failure?
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.
How long does it take to install a gate opener?
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.
Is it possible to open wing for pedestrian mode?
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 (see “Standard & pedestrian mode”)
