6.2.1
Light barrier
Description of function
The light barrier signal interrupts a closing movement a results in reversing.
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 then close.
If the light barrier signal is interrupted while the DOOR CLOSE command is active, the door
is moved in the OPEN direction. An interruption of the light barrier signal while the DOOR
CLOSE command is inactive does not change the state.
If the DOOR CLOSE and Nudge commands are active simultaneously, the light barrier
signal is ignored.
Connection and parameter assignment
The light barrier signal can be connected to the "LIGHT BARRIER / DCPS" input of terminal
X6. See also Section Digital input signals (Page 62). The connected signal must be activated
via the SIDOOR SERVICE TOOL (
Main menu > General setup > Special parameters > Input
1
).
Note
The light barrier and DCPS (Door Closed Position Sensor) (Page 25) functions cannot be
implemented simultaneously.
