SAFETY DEVICES
The sterilizer is equipped with the following safety devices
for which we provide a brief description of their function:
– Mains fuses (see summary table data)
Protection inside the device against a fault in the heating elements.
Action
: cuts the electricity.
– Fuses protecting the electronic circuits (see summary table data)
Protection against a fault in the primary transformer circuit and low voltage uses.
Action: cuts power to one or more low-voltage circuits.
– Thermal circuit breakers on the mains voltage windings
Protection against overheating of the vacuum pump motor and the primary transformer windings.
Action: temporary cut-off (until cooling) of the winding.
– Safety valve
Protection against overpressure in the sterilization chamber.
Action
: release of the steam and restoration of the safety pressure.
– Steam generator manual rearm safety thermostat
Protection against steam generator overheating.
Action: cut-off of the electricity to the steam generator.
– Heating element manual rearm safety thermostat
Protection against overheating of the heating elements of the container under pressure.
Action
: cut-off of the electricity to the chamber heating element.
– Door position safety microswitch
Confirmation of the correct closing position of the door of the container under pressure.
Action: signals wrong door position.
– Mechanized door lock mechanism with electromechanical protection (pressure switch)
Protection against accidental opening of the door (even in a blackout).
Action: prevents accidental opening of the door during a program.
– Door lock mechanism safety microswitch
Confirmation of the correct closing of the door lock.
Action
: signaling the failure or incorrect operation of the door lock mechanism.
– Self-leveling plumbing system
Plumbing system structure for the spontaneous leveling of the pressure in the case of a manual interruption of the cycle,
alarm or blackout.
Action
: automatic restoration of atmospheric pressure in the sterilization chamber.
– Integrated system for evaluating the sterilization process
Continuous verification of the sterilization process parameters entirely managed by microprocessor.
Action
: immediate interruption of the program (in case of anomaly) and generation of alarms.
– Monitoring of the sterilizer's operation
Real-time oversight of all significant parameters when the machine is powered.
Action: generation of alarm messages (in the case of anomaly) with possible interruption of the cycle.
