The CNA#18 potentiometer modulates the current in the
proportional valve connected to the pin#8 of the MDI-
PRC. This proportional valve is normally closed (oil does
not pass-through when de-energized) and directly
connected between the pump and the tank: to do a Lifting
function the voltage into the Proportional Valve is turned
fully On, to direct the oil into the tank before the pump
contactor closes. Then the current in the Proportional
Valve reduces (meanwhile the CNA#18 potentiometer
increases) to accelerate the Lifting. To do a Lowering
function, the current in the proportional valve
progressively increases (meanwhile the CNA#18
potentiometer increases) to accelerate the Lowering.

3:
Only the Main Lifting/Lowering pair (CNB#9 and CNB#8)
is used to handle an On/Off Lifting and a proportional
Lowering. (There is only one proportional valve connected
to the pin#8 of the MDI-PRC to modulate the Lowering).
The CNB#9 input is the Lifting request enabling the pump
contactor on CNA#4.
The CNB#8 input is the Lowering request to enable the
On/Off descent valve connected on CNA#6.
The CNA#18 potentiometer modulates the current in the
lowering proportional valve (pin#8 MDI-PRC) when the
Lowering request is active. To do a Lowering function, the
current in the proportional valve progressively increases
(meanwhile the CNA#18 potentiometer increases) to
accelerate the Lowering.
15) MDI-PRC
This option specifies:
-
PRESENT:
The MDI-PRC is connected to the AC-0 via the CAN Bus:
the handling of the Hydraulics is specified on the TRUCK
TYPE setting below.
-
ABSENT:
The MDI-PRC is not connected to the AC-0: the TRUCK
TYPE disappears from the SET OPTIONS function list.
16) QUICK INV. LOGIC
This option specifies the active level for the Belly switch input (CNB#7)
-
OPTION #1: The quick inversion is executed when CNB#7 is closed to
a KEY voltage.
-
OPTION #2: The quick inversion is executed when CNB#7 is opened
from a KEY voltage.
17) VALVE1 TYPE
(MDI-PRC version only). This option specifies the EVP1 type. The EVP1 is
connected on the pin 8 of the MDI-PRC.
-
OPTION #1: EVP1 is an On/Off valve.
-
OPTION #2: EVP1 is a proportional valve.
18) VALVE2 TYPE
(MDI-PRC version only). This option specifies the Electrovalve #2 type. The
EVP2 is connected on the pin 9 of the MDI-PRC.
-
OPTION #1: EVP2 is an On/Off valve.
-
OPTION #2: EVP2 is a proportional valve
