BOWL LOADING OPERATIONS
Alarms
NOTE: See Acronym Definitions on page 17.
Safety Probe Alarms (only for
ICE FROST GENERIC Pre-mix)
You will remember that the monitoring of the safety probes conditions (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.
When one of the two safety probes (SSIC1 and SSIC2) 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.
The EVCARx connected to the unit where the lack of liquid has been detected by the SSICx can only be
energized by switching the system OFF then ON again. The functions linked to the EVPRESS will not
undergo any changes.
If both the safety probes (SSIC1 and SSIC 2) 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 actuators EVCAR 1 and EVCAR 2 are inhibited (OFF). The normal operation conditions can be
restored by switching the machine OFF then ON again using the main switch.
The EVPRESS solenoid valve is independent of the alarm signal and continues its CO
2
gas
pressure reading function only (see relevant paragraph).
1st Filling Time-out
A time limit has been set for the first filling phase which is linked to the level probes SLIV 1 and SLIV 2s
detection of the presence of liquid.
When one of the two probes (SLIV 1 and SLIV 2) 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 EVCARx connected to the unit where the lack of liquid has been detected by the SSICx can only be
energized by switching the system OFF then ON again.
When both the level probes (SLIV1 and SLIV 2) 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 actuators linked to the system are inhibited (EVCAR 1, EVCAR2, and EVPRESS =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
2s detection of the presence of liquid.
When one of the two probes (SLIV 1 and SLIV 2) 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 EVCARx connected to the unit where the lack of liquid has been detected by the SSICx can only be
energized by switching the system OFF then ONN again.
When both the level probes (SLIV1 and SLIV 2) 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 EVCAR 1 and EVCAR2 actuators are inhibited (OFF). The normal operating conditions can be
resumed by switching the system OFF and then ON again.
The EVPRESS solenoid valve is independent of the alarm signal and continues its CO
2
gas
pressure reading function only (see relevant paragraph).
