OFF Condition

In this condition, the electronic card is not connected to the power supply. To connect the ECU to the

power supply, the main system switch must be put in the ON position.

1st Filling Condition

Supposing both the bowls are empty when the power is switched ON, the following situation will occur:

After a 3 second delay if the four probes, managed by the system, have detected no ‘presence’ of liquid,

the (µcontroller will energies the EVCAR 1 AND EVCAR 2 actuator to allow the correct level refill phase

to begin.

FIGURE 32

Following the system flow, the first probes to be ‘covered’ are the two SSIC1 and SSIC2. However, this

recognition of the passage of liquid does not actually stop the filling phase since the main ‘aim’ of the

ECU is to fill the two bowls to the level required. Therefore only the recognition by SLIV 1 and SLIV 2

interrupts the inlet of liquid into the bowl/s.

FIGURE 33

Once the 1st filling phase is complete, if necessary (see chapter on pressure levels management) the

(µcontroller will enable the EVPRESS, which has been kept forcibly de-energized.

NOTE 1: The 1st loading phase must take place within a maximum time lapse which is controlled by the

(controller (see Alarms section).

NOTE 2: The 1st loading phase may only concern one of the two bowls, but it will maintain the same

features.

NOTE 3: If all the probes are covered when the system is switched ON, the EVPRESS functioning is

enabled.
