4�7�- INPUTS
The
CVM-C10
has two digital inputs (terminals 12 and 13 on
Figure 1, Figure 2 and Figure 3
) that can be
programmed to operate as a logic or tariff selection input.
If configured as a logic input, the device displays the status of that input.
See
“4.9.27. Operating mode of digital input 1”
and
“4.9.28. Operating mode of digital input 2”
The selected tariff can be determined in accordance with the status of the inputs, as shown in
