Electrical installation
“Result 2“ switching output:
Note
If the “Device Ready“ function is chosen, the ICR outputs a static pulse in Reading mode.
For connecting the switching outputs 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).
Tip
The output function, pulse duration (timer) and polarity of the signals can be changed on the

Recommendation
¾
To check the switching functions using a high-impedance digital voltmeter, power the
outputs to prevent incorrect voltage statuses from being displayed.
This prevents incorrect voltage values/switching statuses from being displayed.
