Connecting the “Sensor 1“ switching input
If a reading procedure is to be triggered on the ICR by an external sensor, the reading pulse
sensor must be connected to the “Sensor 1“ switching input. The trigger type is selected in
the default setting of the ICR.

For connecting the “Sensor 1“ switching input via the CDB 420 or CDM 420 Connection
Module, see the “
CDB 420 Connection Module“ Operating Instructions (order no. 8 010
001, German/English version)
respectively the
“CDM 420 Connection Module“ Operating
Instructions (order no. 8 010 004, German/English version).
Note
An external pulse is not required for “Percentage Evaluation“ mode.
