Electrical installation
¾
Connect the outputs as shown in
"
Note
If the "Device Ready" function is chosen, the CLV outputs a static pulse in Reading mode.
For connecting the host interface via the AMV/S 60 Connection Module, see the Operating
Instructions for the "
AMV/S 60 Connection Module
" (no. 8 008 296).
Tip
The output function, pulse duration (timer), and polarity of the signals can be changed on
the D

C
ONFIGURATION
tab in the "CLV-Setup" program.
¾
Click the E

button and enter the values in the dialog box displayed.
Recommendation
¾
To check the switching functions using a high-impedance digital voltmeter, connect a
load to the outputs to prevent incorrect voltage values/switching statuses from being
displayed.
