9 Safety devices
1. Main breaker: Protection of the instrument against possible failures of the heating resistor.
Action: Interruption of the electric power supply.
2.Thermal cutouts on the main transformer winding: protection against possible short circuit and main
transformer primary winding overheating
Action: Temporary interruption of winding.
3.Safety valve: Protection against possible sterilization chamber over-pressure.
Action: Release of the steam and restoration of the safety pressure.
4.Safety micro-switch for the door status: Comparison for the correct closing position of the door.
Action: Signal of the wrong position of the door
5.Thermostat on chamber heating resistors: Protection for possible overheating of the chamber heating
resistors.
Action: Interruption of the power supply of the chamber resistors.
6.Thermostat on steam generator heating resistors: Protection for possible overheating of the steam
generator heating resistors.
Action: Interruption of the power supply of the steam generator resistors.
7.Door safety lock: Protection against accidental opening of the door.
Action: Impediment of the accidental opening if the door during the program.
8.Self-leveling hydraulic system: Hydraulic system for the natural pressure leveling in case of manual
cycle interruption, alarm or blackout.
Action: Automatic restoration of the atmospheric pressure inside the chamber.
