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 "
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.

Maintenance data

Description of function
For maintenance purposes, the SIDOOR controller determines operating data of the
controller, the motor and the door mechanics. These values can be used to determine the
service life and frequency of use. In addition, changes in the driving characteristics of the
motor and the door can be detected and evaluated for maintenance purposes.
The maintenance data can be queried via the SIDOOR SERVICE TOOL (Page 118) or via
the CANopen interface.
