The CVM-E3-MINI device has 2 LEDs:
- CPU, indicates that the device is on, flashing each second.
- ALARM / ENERGY PULSES; if this is on, it indicates that an alarm or an energy pulses output
has been activated. In the case of the energy pulses, the LED will be lit and flash with the rate

4.5.- DIGITAL INPUT (Models CVM-E3-MINI-xxx)
The CVM-E3-MINI-xxx has one digital input (terminals S and 9 on Figure 4) that can be programmed
to operate as a logic input, tariff selection or pulse counter.
The operation of the input as a pulse counter is independent of the programming of the digital input,
that is, the device can be used as a logic input or tariff selection at the same time as a pulse counter.
The configuration of the digital input as pulse counter can only be done by communications, see
“7.3.8.12. Digital input (Models CVM-E3-MINI-xxx)”.
If configured as a logic input, the device displays the status of that input. See “6.19. OPERATING MODE
OF DIGITAL INPUT (Models CVM-E3-MINI-xxx)”.
Press the keys to access the digital input status screen, see “5.4.- DIGITAL INPUT AND OUT-
PUT STATUS SCREEN (Models CVM-E3-MINI-xxx)”.
The selected tariff can be determined in accordance with the status of the inputs, as shown in Table 17.
