Managing the Bowl Levels

When one of the two level probes (SLIVx) fails to detect the presence of liquid in the bowl, the EVCARx

is enabled to restore the correct level.

The probes relating to each bowl are completely independent, therefore the following situation will occur:

NOTE 1: The level/s refill phase must take place within a maximum time lapse which is controlled by the

(controller (see Alarms chapter).

NOTE 2: The level/s refill phase may only concern one of the two bowls, but it will maintain the same

features.

NOTE 3: It is essential that the safety probes are covered for the bowl/s filling phase to take place.

Safety Probes (only for ICE FROST GENERIC Pre-mix)

In addition to the two level probes relating to the two bowls (see FIGURE 32 through FIGURE 35), the

µZ4LP system also monitors the two ‘safety’ probes designed to monitor the presence of liquid in the

external tanks.

The monitoring of the condition of the safety probes (covered/uncovered) is only active during the bowl

loading phase. It follows, then, that a lack of liquid in the tanks during the non-loading phases will not be

signalled.

If: SSIC1 “KO” when EVCAR 1 = OFF - no signal

SSIC2 “KO” when EVCAR 2 = OFF - no signal

Example of how the safety system works:

Supposing the safety probe SSIC 1 is uncovered and the solenoid valve EVCAR 1 is de-energized. In

this case there will be no signal.

Then the level probe SLIV 1 located in the bowl 1 is uncovered. The solenoid valve EVCAR 1 is enabled

to allow the bowl 1 to fill up correctly.
