Manual disengagement
The opener is equipped with a manual release cord to disengage shuttle and move door by hand
while holding the handle down (Fig 19). Pull on the handle to disengage the shuttle. To re-engage
the door simply run opener in automatic mode or move door by hand until the trolley engages in the
chain shuttle.
In some situations that a pedestrian door is not in state, it is recommended that an external
disengagement device should be fitted (Fig 20).

Maintenance
No particular maintenance is required for the logic circuit board.
Check the door at least twice a year if it is properly balanced, and all working parts are in good
working condition or not.
Check the reversing sensitivity at least twice a year, and adjust if it is necessary.
Make sure that the safety devices are working effectively (photo beams, etc.)
Notice: A rude operating door can affect the life of the automatic opener due to incorrect loads,
and will void the warranty.
