The parallel inputs are active for input voltages in the range of 15 V to 30 V and inactive
for voltages < 9 V. Not connected (n.c.) inputs are internally connected to ground. For
the inputs, a variable debounce time can be set (refer to menu
Output-Input Set-
tings
in section 4.4 on page 26).
The parallel output drivers apply 24 Volts to the terminals and are short circuit proof.
In case a short circuit occurs, the corresponding output will be switched off. The red
bus LED is continuously alit, as long as the error is there and the corresponding status
bit is set. This situation is managed depending on the operating mode:
IN4
Select parameter set
Ground
Ground for digital outputs OUT1 - OUT 8
OUT1
Lateral deviation > +threshold 1
or: lowest barcode bit C0
OUT2
Lateral deviation > +threshold 2
or: barcode bit C1
OUT3
Lateral deviation < -threshold 1
or: barcode bit C2
OUT4
Lateral deviation < -threshold 2
or: barcode bit C3
OUT5
pulse output with adjustable length and time lag: barcode decoded
