Light Barrier - Siemens SIDOOR AT40 System Manual

Light barrier

Description of function
The input for the light barrier signal has the same function as the OPEN DOOR command.
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.
If the light barrier signal is interrupted while the CLOSE DOOR command is active, the door
is moved in the OPEN direction. An interruption of the light barrier signal while the CLOSE
DOOR command is inactive does not change the state.
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 51). The connected signal must be activated
via the SIDOOR Service Tool, Terminal Editor or SIDOOR SOFTWARE KIT (
General setup > Special parameters > Input 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 51).
Note
The light barrier and DCPS (Door Closed Position Sensor) (Page 24) functions cannot be
implemented simultaneously.
The light barrier and emergency power mode (Page 44) functions cannot be implemented
simultaneously.
