1.4.2 Protection against unbalance

The suspended aseptic or CS machines are fitted with one or two unbalance protections, according to their load capacity. These avoid excessive oscillations caused by a strong unbalance by interrupting the centrifugal motion.

Effect of the protections in case of a strong unbalance

•During the final centrifuge, the centrifugal motion is interrupted and the drainage is maintained, but the cycle is frozen. The message “E9 or unbalance fault” is shown on the display. One must restart the cycle and move fast forward through the program to arrive at the centrifuge phase again.

1.4.3 Heater protection

The bath heating system is not switched on unless the pressure meter, installed for this purpose, detects the correct water level.

1.4.4 Security related to gas heating system

Four security systems guarantee the correct operation of the system.

•When no flame is detected in the burner, the igniter and control plug of the flame causes the closure of the electronic valve in the gas feed, while message “E13” appears on the micro control display. After waiting for about 20 seconds you may then restart the system by a key combination for machine with micro control. If the default appears again, one of the following faults has occurred:

o No gas feed: check whether the gas feed valves are open. o Igniter plug broken.

•The thermostat (chimney obstructed” interrupts the power supply to the command module, in case the chimney is obstructed, and informs you of this fault on the terminal display showing “E10 or chimney obstructed”. After several minutes, you may restart the cycle by pressing “start”. Check your chimney when the fault persists.

•The thermostat “heating security” also interrupts the command module when the temperature in the heater is abnormal and informs you of this fault on the terminal display showing “E11 or heating security”.

•The thermostat “water failure security” also interrupts the command module when the heating element overheats and informs you of this fault on the terminal display showing “E12 or water failure security”.
