Pull to close
Description of function
When the door is pulled manually more than 2 cm in the closing direction, the controller
automatically detects the command DOOR CLOSE.
See also section DOOR CLOSE (command given via digital inputs) (Page 19).
3.4.5
Obstruction detection
3.4.5.1
Obstruction detection CLOSE
Description of function
If the door is obstructed in the CLOSE direction with a DOOR CLOSE command present, the
door stops and reverses direction. After reaching the OPEN position, the door closes again at
normal speed to within about 2 cm of the obstruction. It then travels at reduced speed (cutter
speed) against the obstruction before reversing again. The function is repeated the number
of times specified in the "Number of CLOSE obstructions before wait mode" parameter.
When the configured number of obstructions has been reached, the door remains stationary
at the obstruction position. No door commands are executed for the period of time specified
in the "Time delay in wait mode CLOSE" parameter. If there is no door command after the
wait time has expired, the door travels in the CLOSE direction. This function is repeated
continuously, as long as the obstruction remains.
Once the obstruction has been cleared, the door travels at reduced speed to approximately
2 cm past the stored position of the obstruction, and then continues the rest of the way at
normal closing speed.
