Photo cell
A photo cell is used for presence detection. It is only active in door operating modes "3" and
"4", in the OPEN final limit position or during the closing operation.
If the photo cell is interrupted, fault indication "F2.1" appears.
Light curtain
The light curtain must be self-testing and correspond at least to safety category 2 or
performance level c (plc). If the light curtain corresponds to these requirements, the door can
close into self-hold without safety edge system.
