6. FUNCTIONS
6.1 Power supply mode
EVD evolution twin can be powered at 24 Vac or 24 Vdc. In the event of direct
current power supply, after completing the commissioning procedure, to
start control set “Power supply mode” parameter=1.

Tab. 6.a
Important: with direct current power supply, in the event of power
failures emergency closing of the valve is not performed, even if the
EVD0000UC0 module is connected.
6.2 Battery charge delay
Battery charge delay to allow battery charging. In the presence of a battery to
close the valve, to avoid missing emergency closing in case of repeated and
close blackouts, a regulation start delay has been introduced, congurable by
the user depending on the backup system used (ultracap or lead battery). This
delay, if set to a value> 0, occurs every time the driver is turned on to allow
the battery to recharge.

Battery charge delay 0 min
6.3 Network connection
Important: to set the pLAN address, follow the guidelines in chap.4.
To connect an RS485/Modbus® controller to the network, as well as the
network address parameter (see paragraph 4.2), using the “Network settings”
parameter.

6.4 Inputs and outputs
Analogue inputs
The parameters in question concern the choice of the type of pressure/liquid
probe S1 and S3 and the choice of the temperature probe S2 and S4, as
well as the possibility to calibrate the pressure and temperature signals. As
regards the choice of pressure/liquid probe S1 and S3, see the chapter on
“Commissioning”.
Inputs S2, S4
The options are standard NTC probes, high temperature NTC, combined
temperature and pressure probes and 0 to 10 Vdc input. For S4 the 0 to 10
Vdc input is not available. When choosing the type of probe, the minimum
and maximum alarm values are automatically set. See the chapter on “Alarms”.

Calibrating pressure probes S1, S3 and temperature
probes S2 and S4 (oset and gain parameters)
If needing to be calibrate:
• the pressure probe, S1 and/or S3, the oset parameter can be used, which
represents a constant that is added to the signal across the entire range of
measurement, and can be expressed in barg/psig. If the 4 to 20 mA signal
coming from an external controller on input S1 and/or S3needs to be
calibrated, both the oset and the gain parameters can be used, the latter
which modies the gradient of the line in the eld from 4 to 20 mA.
• the temperature probe, S2 and/or S4, the oset parameter can be used,
which represents a constant that is added to the signal across the entire
range of measurement, and can be expressed in °C/°F. If the 0 to 10
Vdc signal coming from an external controller on input S2 needs to be
calibrated, both the oset and the gain parameters can be used, the latter
which modies the gradient of the line in the eld from 0 to 10 Vdc.
