You can use the advanced features described below to implement application-specific
requirements.
4.3.1

Obstruction detection

4.3.1.1

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 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.
4.3.1.2

Obstruction detection OPEN

Description of function
The door stops if it is obstructed in the "OPEN" direction when the OPEN DOOR command is set.
After approximately 2 s, the door automatically tries to reach the OPEN position again. This
action is repeated a maximum of 3 times. The door then remains stationary in this position.
If the OPEN DOOR command is canceled, the close command given, and the OPEN DOOR
command is then repeated, the door travels at normal speed to within about 2 cm of the stored
position of the obstruction, and then up to the obstruction at reduced speed.
The door drive stops at the obstruction and the opening action is repeated another 3 times. If the
obstruction has been removed beforehand, the door travels at a reduced speed approximately
2 cm past the stored position of the obstruction, and then continues to the OPEN position at
normal speed.
The number of opening attempts can be set when an obstruction is detected in the opening
direction via the service menu with "Quick setup > Reversing system > Opening attempts".
This setting may be required when using glass and folding doors.
The default value is 3 opening attempts. If the value 0 is set, no opening attempts are performed
and the motor is deenergized once the obstruction has been detected.
