3 seconds (software hysteresis) after the activation of the solenoid valve EVCAR 1, the safety signal is

activated as the probe SSIC 1 has been identified as uncovered. The loading solenoid valve EVCAR 1 is

therefore deactivated and the buzzer emits an intermittent signal lasting 6 seconds.

NOTE 1: the same intervention methods are applied when the safety probe

is uncovered after the solenoid valve EVCAR 1 has been activated.

NOTE 2: the 3-second software filter activated when it detects the safety probe is uncovered and the

relevant signal have been introduced to prevent the probe recognizing the “tank-bowl” conduit as “empty”

when there is residual gas in it.

Summing Up:

• When one of the two safety probes SSICx fails to detect the passage (presence) of liquid during the

loading phase, the system will stop (3-second software filter) the loading phase in progress, while

the buzzer on the machine emits an intermittent warning signal lasting 6 seconds.

• If the safety probes SSICx is uncovered when there is no loading phase in progress (therefore

EVCARx is de-energized), no alarm signal is emitted.

This signal is activated as soon as the system starts to load the bowl.

If: EVCAR1 = ON and SSIC1 = OK bowl 1 is filled as usual

EVCAR2 = ON and SSIC2 = OK bowl 2 is filled as usual

If: EVCAR1 = ON and SSIC1 = KO after 3 seconds - EVCAR 1 = OFF and buzzer is activated

EVCAR2 = ON and SSIC2 = KO after 3 seconds - EVCAR 2 = OFF and buzzer is activated

ATTENTION: After the no liquid alarm signal has been activated (SSICx uncovered), the actuators

for the bowl whose safety probe is uncovered cannot be re-activated. Full functioning conditions

can only be restored by switching the machine OFF then ON again and re-starting from the 1st

filling phase. When the second safety probe is also identified as uncovered, all the charges

relating to the system are inhibited (with the exception of EVPRESS) and the buzzer emits an

intermittent sound for approximately 20 seconds. Full functioning conditions can only be

restored by switching ON and OFF the machine starting from the 1st filling phase.

The EVPRESS solenoid valve is independent of the alarm signal and continues its CO

gas

pressure reading function only (see relevant paragraph).
