Technical description LSIS 22x
Leuze electronic
Connecting functional earth FE
Attention!
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 discharged via the functional earth connection.
Switching input/output
The LSIS 22x code readers are equipped with both an opto-decoupled
SWI
switching input
and
SWO
switching output.
The LSIS 22x can be activated with the switching input (triggering of code reading).
The switching output is used to signal '
good read
' read processes. If a read process is
successful, a high pulse
lasting 80 ms
is output at the switching output.

Attention!
The switching output is short-circuit proof! However, do not load the switching output of
the LSIS 22x with more than 20mA in normal operation!
