4.6.- DIGITAL INPUTS
The CVM-C11 has two digital inputs (terminals 9, 10 and 11 on Figure 1) programmable to function as
logic input, tariff selection (Figure 35) or to generate a synchronism pulse to calculate the maximum
demand.
If configured as a logic input, the device displays the status of that input. See “6.29.- OPERATING MODE
OF DIGITAL INPUT 1” and “6.30.- OPERATING MODE OF DIGITAL INPUT 2”.
The selected tariff can be determined in accordance with the status of the inputs, as shown in Table 20.
