LiftMaster LM50EVFF Notice De Montage page 9

16. The door releases by itself from the carriage and stops:
• An external release that has been installed during a power failure
should be checked whether it stretches and releases during the open-
ing of the door. Watch the mechanism and reset if necessary.
• The handle of the release mechanism should not get caught in other
items.
17. The running path cannot be programmed, is de-programmed
or is changing slowly:
• The programmed running path is too short. Programme a longer path
for testing purposes.
• A small plastic knob is factory-mounted on the chain that is running in
the rail. During the travel of the opener this little button must press the
small switch located on the drive head. If the path is too short or the
button was torn down by incorrect installation, it has to be fixed again.
If the small switch is not pressed, the programming of the opener is not
possible.
• A mechanical fault at the door due to deected joints or the chain
tension on the drive is too loose.
