Connecting functional earth FE
Ensure that the functional earth (FE) is connected correctly. Unimpaired operation is only guaranteed
when the functional earth is connected properly. All electrical disturbances (EMC couplings) are dis
-
charged via the functional earth connection.
Switching input/output
The device is equipped with four freely programmable, opto-decoupled switching inputs and outputs
SWIO_1 … SWIO_4.
The switching inputs can be used to activate various internal functions of the device (decoding, autoConfig,
…). The switching outputs can be used to signal the state of the device and to implement external functions
independent of the superior control.
The two switching inputs/outputs SWIO_1 and SWIO_2 are located on the SW IN/OUT M 12 socket (see
chapter 7.4). The other two (SWIO_3 and SWIO_4) of the four freely configurable switching inputs/outputs
are located on the PWR M 12 connector.
The external wiring as switching input and switching output is described in the following. For the respective
function assignment to the switching inputs/outputs see chapter 10.

CAUTION
For UL applications, use is only permitted in Class 2 circuits in accordance with the NEC (National
Electric Code).
CAUTION
The bar code readers of the BCL 600i series are designed in accordance with protection class III for
supply by PELV (protective extra-low voltage with reliable disconnection).
The respective function as input or output can be set via the display or with the aid of the
“webConfig” configuration tool!
