FUNCTION DESCRIPTION
Door overload monitor
The door overload monitor recognises that a person is being lifted by the door (hanging on a
handle, etc.) and could be adjusted within
Menu 3.1
with a possibility of two steps of sensitivity.
Adjustment 0.1 sensitive reaction and adjustment 0.2 insensitive reaction
When an overload is detected the door works only Dead man Mode in the UP and DOWN
direction.
The control unit automatically resets to impulse control when a final limit position has been
reached.
Important!
After programming the force monitoring the door must perfom a
complete opening and closing cycle without an interruption.
Durich which the system reads the increments to calculate the way.
Important Note!
The overload monitor does not take place against other safety devices e.g.
(safety against entrapment)
The overload monitor is a self-learning system, and checks the system from 5 cm up to ca.
2,0 m, slow-occurring changes e.g. spring tension will be automatically recognised and
equalized.
Important Note!
To have a trouble-free service the following points must be checked:
- The door must be correctly balanced
- The cable drum diameter should not be less then 160mm
Environmental influences e.g. temperature or wind load can cause the
overload monitor to be activated.
