The CMC600 automatically transmits the
output states of its physical “Aux In 1 and
2” inputs to the serial Aux interface of the
CLV69x via the connecting cable using
software.
The CLV69x translates the statuses to its
logical “External input 1 and 2“ inputs.
“External
input 1,
input 2”
Characteristic data of switching inputs “Ext. input 1 and 2”
Current at the input starts the assigned
function, e.g. start reading cycle. (CLV69x

cing 10 mm)
– Opto-decoupled, reverse polarity protected
– Can be wired with PNP output of a sensor
– SensGND is the common insulated
reference potential for all switching inputs
