4.2.1 Inputs
The inputs are used to connect peripheral units and sensors. The inputs are activated while
they are pulled to GND (0 Volt). The peripheral units from Collamat Stralfors AG have NPN-
outputs to 0 Volt.
Figure 12 shows the schematic diagram of the inputs:
On
: >4mA (or < 2 V)
Off
: 0mA (or > 8 V)
Vmax
: 24 V
Figure 12: Signal input
An input is then active, when a current of minimum 4mA is pulled to GND. The following inputs
are available:
GSC1
Goods scanner
LSC
Label scanner
READY
READY-signal for peripheral units
