24V: then it is necessary that the MDI-PRC generates an output voltage with

a PWM tecnique never overtaking the 50% Duty Cycle to get the Valve’s

voltage less equal than 24V. Through this setting it is possible to take care

the voltage on the EVD1 and EVD2 never overcomes the nominal voltage of

the valves.

23) VALVE 3 VOLTAGE

(MDI-PRC version only). A percentage from 0% to 100%. This parameter

determines the voltage applied to the EVD1 (this is connected on the pin #6

of the MDI-PRC) in percentage of the above VALVES VOLTAGE setting. The

voltage applied to this electrovalve is a PWM tecnique generated by the MDI-

PRC: the Duty Cycle is modulated in order that, the voltage applied to these

On/Off valve, is the wished percentage of the VALVES VOLTAGE (e.g.

Vbatt=48V, VALVES VOLTAGE=24V, VALVE 3 VOLTAGE=100% means the

MDI-PRC generates a PWM with a 50% duty on the EVD1).

24) VALVE 4 VOLTAGE

(MDI-PRC version only). A percentage from 0% to 100%. This parameter

determines the voltage applied to the EVD2 (this is connected on the pin #4

of the MDI-PRC) in percentage of the above VALVES VOLTAGE setting. The

voltage applied to this electrovalve is a PWM tecnique generated by the MDI-

PRC: the Duty Cycle is modulated in order that, the voltage applied to these

On/Off valve, is the wished percentage of the VALVES VOLTAGE (e.g.

Vbatt=48V, VALVES VOLTAGE=24V, VALVE 4 VOLTAGE=100% means the

MDI-PRC generates a PWM with a 50% duty on the EVD2).

25) V1 OPENING RAMP

(MDI-PRC version only). A time units value (from 0.0 to 2.0 seconds). This

parameter determines the ramp of voltage applied on the EVP1 (pin #8 MDI-

PRC) in the opening transition (if proportional); this is the time necessary to

go from the minimum to the maximum voltage. If the electrovalve is

programmed like an On/Off valve this parameter is not effective.

26) V2 OPENING RAMP

(MDI-PRC version only). A time units value (from 0.0 to 2.0 seconds). This

parameter determines the ramp of voltage applied on the EVP2 (pin #9 MDI-

PRC) in the opening transition (if proportional); this is the time necessary to

go from the minimum to the maximum voltage. If the electrovalve is

programmed like an On/Off valve this parameter is not effective.

27) V1 CLOSING RAMP

(MDI-PRC version only). A time units value (from 0.0 to 2.0 seconds). This

parameter determines the ramp of voltage applied on the EVP1 (pin #8 MDI-

PRC) in the closing transition (if proportional); this is the time necessary to go

from the maximum to the minimum voltage. If the electrovalve is programmed

like an On/Off valve this parameter is not effective.

28) V2 CLOSING RAMP

(MDI-PRC version only). A time units value (from 0.0 to 2.0 seconds). This

parameter determines the ramp of voltage applied on the EVP2 (pin #9 MDI-

PRC) in the closing transition (if proportional); this is the time necessary to go

from the maximum to the minimum voltage. If the electrovalve is programmed

like an On/Off valve this parameter is not effective.
