Electrical connection
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).
Note If the "Device Ready" function is chosen, the CLV outputs a static pulse in Reading mode.
Tip
The output function, pulse duration (timer) and polarity of the signals can be changed on the
DEVICE CONFIGURATION tab in the CLV Setup program.
 Click the RESULT OUTPUT PARAMETERS button. Edit dialog box.
Download all changes to CLV.
Recommendation  To check the switching functions using a high-impedance digital voltmeter, power the
outputs.
This prevents incorrect voltage values/switching statuses from being displayed.
