INSTALLATION – DS8100 BUS INTERFACE

3.3.2 Inputs
The inputs for the DS8100 Bus Interface version are provided by SC8000 and are
called ENC, PS and PSAux.
ENC is the Encoder input. In PackTrack™ operating mode, it detects the conveyor
speed.
PS is the main presence sensor (external trigger). When active, this input tells the
scanner to scan for a code and that decoding can take place. The yellow LED (Figure
B, 9) indicates that PS is active.
PSAux can be used in special applications.
All inputs are optocoupled and driven by a constant current generator; the command
signal is filtered through an anti-disturbance circuit which generates a delay of about
5 ms for PS and PSAux and 500 µs for ENC.
