18 MAX VALVE 1: this parameter determines the maximum voltage
applied on the electrovalve 1 when the position of the
potentiometer is at the maximum. If the electrovalve 1
is programmed like a On/Off valve (see the
configuration chapter) this parameter determines the
voltage applied on the electrovalve coil.
19 MAX VALVE 2: this parameter determines the maximum voltage
applied on the electrovalve 2 when the position of the
potentiometer is at the maximum. If the electrovalve 2
is programmed like a On/Off valve (see the
configuration chapter) this parameter determines the
voltage applied on the electrovalve coil.
20 VALVES VOLTAGE this parameter determines the nominal voltage of the
On/Off valves coil (valve 3 and 4). For example, if 24V
coil valves are installed, this parameter must be set at
24V. In this way, MDI-PRC will drive the coil at 24V,
regardless of the battery voltage.
21 VALVE 3 VOLTAGE: this parameter determines the voltage applied on the
electrovalve 3.
22 VALVE 4 VOLTAGE: this parameter determines the voltage applied on the
electrovalve 4.
23 V1 OPENING RAMP: this parameter determines the ramp of voltage applied
on the electrovalve 1 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.
24 V2 OPENING RAMP: this parameter determines the ramp of voltage applied
on the electrovalve 2 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.
25 V1 CLOSING RAMP: this parameter determines the ramp of voltage applied
on the electrovalve 1 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.
26 V2 CLOSING RAMP: this parameter determines the ramp of voltage applied
on the electrovalve 2 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.
