FUNCTIONING
1.2 WARM-UP
When the door is closed, if one of the 6 available sterilization cycles is selected and activated, the door is locked and
the WARM-UP phase is activated.
During this phase are warmed up:
- chamber by the chamber heating element;
- generator by the generator heating element;
until reaching the following temperature levels.
- tube bundle heating element > PT3 temperature reading - 110°C;
- generator heating element > PT2 temperature reading - 140°C;
- chamber > PT1 temperature reading - 60°C.
When the above values are reached, the next phase begins. This is the 1
st
VACUUM PHASE.
The 1
st
VACUUM PHASE will start after 10 minutes even though the temperature readings are below the values listed
above.
The WARM-UP phase is divided into 2 sections:
- section 1 continues until PT2 temperature reading = 110°C
- section 2 continues until PT2 temperature reading = 140°C
During section 2 of the WARM-UP phase, the following components are turned on:
- vacuum pump
- solenoid valve EV2 (air suction)
- solenoid valve EV4 (vacuum pump bypass)
so that the pump reaches its regular operating conditions and any condensate in the tubes is eliminated.
