6.3.2 Connecting the switching input/output
The BCL 8 is provided with a switching input or a switching output. You can configure the respective func
-
tion (input or output) according to your requirements using the Sensor Studio program.
Switching input (default)
By means of the SW IN/OUT combined switching input/output connection, you can trigger a read process
in the standard setting (low = active) with the connection SW IN/OUT (pin 5) and GND (pin 3). The 2.2 k
:
"pull-up" resistor must be connected externally (connection version 1, Figure 6.4).
ATTENTION!
The BCL 8 bar code reader is completely sealed and cannot be opened.
Do not try to open the device under any circumstances, as this avoids both degree of protection
IP 67 and the warranty.
Before connecting the device, be sure that the supply voltage agrees with the value printed
on the name plate.
Connection of the device and maintenance work while under voltage must only be carried out
by a qualified electrician.
The power supply unit for the generation of the supply voltage for the BCL 8 and the corre
-
sponding connection units must have a secure electrical insulation according to IEC 60742
(PELV). For UL applications: only for use in class 2 circuits according to NEC.
Take care to connect the protective conductor correctly to the housing screen. Fault-free oper
-
ation is only guaranteed when the device is properly earthed.
If faults cannot be cleared, the device should be switched off and protected against accidental
use.
