You will remember that the monitoring of the safety probes’ conditions (satisfied/ not satisfied) 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.
When one of the two safety probes fail to detect the flow (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.
The fill solenoid connected to the system where the lack of liquid has been detected by the safety probe
input can only be energized by switching the system OFF then ON again (cycling power resets fill
operation).
If both the safety probes fail to detect a presence of liquid while the bowls are loading, the buzzer on the
card will emit an intermittent sound lasting approximately 20 seconds.
The bowl fill solenoids are command (OFF). The normal operation conditions can be restored by
switching the machine OFF then ON again using the main switch.
The bowl pressure valve solenoid valve is independent of the alarm signal and continues its
CO
2
gas pressure reading function only.
1st Filling Time-out
A time limit has been set for the first filling phase which is linked to the level probes detection of the
presence of liquid.
When one of the two level probes fails to detect the presence of liquid for more than four seconds, the
buzzer on the card will emit an intermittent sound for approximately 6 seconds.
The fill solenoid connected to the system where the lack of liquid has been detected by the safety probe
input can only be reset by switching the system OFF then ON again.
When both the level probes fail to detect a presence of liquid for more than four seconds, the buzzer on
the card emits an intermittent sound lasting approximately 20 seconds.
All the solenoids linked to the system are inhibited (bowl fill and CO
2
gas management valves = OFF).
The normal operating conditions can be resumed by switching the system OFF and then ON again.
Filling Time-out
A time limit has been set for the normal filling phase which is linked to the level probes SLIV 1 and SLIV
2’s detection of the presence of liquid.
When one of the two level probes fails to detect the presence of liquid for more than one minute, the
buzzer on the card will emit an intermittent sound for approximately 6 seconds.
The fill solenoid connected to the system where the lack of liquid has been detected by the safety probe
input can only be energized by switching the system OFF then ON again.
When both the level probes fail to detect a presence of liquid for more than on minute, the buzzer on the
card emits an intermittent sound lasting approximately 20 seconds.
The bowl fill solenoids are command (OFF). The normal operating conditions can only be resumed by
switching the system OFF and then ON again.
The CO
2
gas management valve solenoid valve is independent of the alarm signal and
continues its CO
2
gas pressure reading function only (see relevant paragraph).
