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
opening 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 (+120 cm).
• A mechanical fault at the door due to deflected joints or the chain
tension on the drive is too loose.
