Obstruction detection
6.2.10.1
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 (creep speed) against the
obstruction before reversing again. 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.
Note
CLOSE obstruction detection is only available in normal operation. During initial operation,
obstruction detection serves to detect the end position.
6.2.10.2
Obstruction detection OPEN
Description of function
The door stops if it is obstructed in the "OPEN" direction when the DOOR OPEN command
is present.
After approximately 2 s, the door automatically tries to reach the OPEN position again. This
action is repeated a maximum of 3 times. The motor is then deenergized.
If the DOOR OPEN command is canceled, the close command given, and the DOOR OPEN
command then repeated, the door travels at normal speed to within approx. 2 cm of the
stored position of the obstruction, and then up to the obstruction at reduced speed (creep
speed). The door drive stops at the obstruction, and the opening action is repeated another
3 times.
If the obstruction has been removed, the door travels at reduced speed to approximately
2 cm past the stored position of the obstruction, and then continues to the OPEN position at
normal speed.
Note
OPEN obstruction detection is only available in normal operation. During initial operation,
obstruction detection serves to detect the end position.
