When temperature of heating coil(T3) rised and less than 100
℃
,screen will show Fig.5.3-20 interface (the heating coil pre-heating stage).
When temperature of heating coil(T3) rised and over than 100

time countdown.If the vacuum value reaches Pv value ahead of time, sterilization
program goes into heating stage in advance.
ATTENTION:If the vacuum value of less than Pv (factory default setting Pv=-0.800bar) in

, there will be with alarm E12.
5.3.2.2.THE FIRST TIMES HEATING STAGE(Fig.5.3-23)
When the vacuum value reachs Pv value,the contrl system will open the water pump-solenoid valve(Ev2).The steam generator start inject the
steam into chamber,the temperatures(T1 and T2) and pressure inside the chamber will be rised at the same time.
5.3.2.3.THE FIRST TIMES EXHAUST STAGE(Fig.5.3-24)
When the pressure inside the chamber reachs 1.100bar,the control system will open the exhaust-solenoid valve(Ev1) for exhausting untill pressure
downs to P=0.000bar.LCD shows

5.3.2.4.THE SECOND TIMES HEATING STAGE(Fig.5.3-25)
When the pressure inside the chamber reaches 0.000bar,the control system will open the water pump-solenoid valve(Ev2).The steam generator
start to inject the steam into chamber,the temperature(T1 and T2) and pressure inside the chamber will be rised at the same time.
5.3.2.5.THE START STERILIZATION STAGE(Fig.5.3-26)
When the temperature inside chamber reaches ,the control system will start sterilizing.LCD shows
