Light barrier

Description of function
If the light barrier signal is interrupted while the DOOR CLOSE command is active, the door is
moved in the OPEN direction.
Exception: If the door is open less than 1 cm, the light barrier signal is ignored. If no power is
supplied at the light barrier input, this is interpreted as an interruption of the light barrier. The
door cannot close in this case.
An interruption of the light barrier signal while the CLOSE DOOR command is inactive does not
change the state.
Complete opening in case light barrier is interrupted
The reaction of the door in case the light barrier is interrupted can be set as of V1.47. If the "MAIN
MENU > General setup > Special parameters > Full opening" parameter is deactivated (default
setting), the door only travels as long as the light barrier is interrupted. If the parameter is
activated, the door opens completely in case the light barrier is interrupted.
Connection and parameter assignment
The light barrier signal can be connected to the light barrier/DCPS input of terminal X6 pin 5/6.
See also section Digital input signals (Page 68). The evaluation of the light barrier signal must
be activated via the SIDOOR SERVICE TOOL, Terminal Editor or SIDOOR SOFTWARE KIT (MAIN
MENU > General setup > Special parameters > Inp. 1).
Input "Input 0" (terminal X5) can be configured via the service menu "General setup > Special
parameters > Input X5" as a light barrier feedback contact (FC light barrier). For more, see also
section Digital input signals (Page 68).
Note
The light barrier and DCPS (Door Closed Position Sensor) (Page 42) functions cannot be
implemented simultaneously.
The light barrier and emergency power mode (Page 62) functions cannot be implemented
simultaneously.
This function must be enabled for the light barrier to work correctly (Special parameters -> Input
1).
Note
A learn run "when the line voltage is applied (Page 38)" resets input 1 to the basic setting "light
barrier". If no light barrier is connected to the door control unit, either input 1 must be
deactivated via the menu "General setup -> Special parameters -> Input 1" - or the light barrier
bridges must be inserted (see (Page 68)).
