shows the interaction between the switching outputs and the “Light path
interrupted“ LED during optical data transmission. The output circuits and the characteristic
data of the outputs are shown in

The “Transmitter off“ switching input can be used to switch off the transmitter on the
unit if necessary. A voltage of +24 V must be applied for this purpose.
The input circuit and the characteristic data are shown in
