APPENDIX A – TECHNICAL CHARACTERISTICS
51.
SAFETY DEVICES
The sterilizer is equipped with the following safety devices:
– Mains fuses (see summary table data)
Protects inside the device against a fault in the heating elements.
Action: cuts the electricity.
– Fuses protecting the electronic circuits (see summary table data)
Protects 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
Protects against overheating of the vacuum pump motor and the primary transformer windings.
Action: temporary cut-off (until cooling) of the winding.
– Safety valve
Protects against overpressure in the sterilization chamber.
Action: releases the steam and restores to a safe pressure.
– Steam generator manual re-arm safety thermostat
Protects against steam generator overheating.
Action: cuts-off the electricity to the steam generator.
– Heating element manual re-arm safety thermostat
Protects against overheating of the heating elements of the container under pressure.
Action: cuts-off the electricity to the chamber heating element.
– Door position safety microswitch
Confirms the door is correctly closed when the container is under pressure.
Action: signals incorrect door position.
– Mechanized door lock mechanism with electromechanical protection (pressure switch)
Protects against accidental opening of the door (even in a blackout).
Action: locks the door.
– Door lock mechanism safety microswitch
Confirms the door lock is operating correctly.
Action: signals the failure or incorrect operation of the door lock mechanism.
– Self-leveling plumbing system
Plumbing system structure that allows for the spontaneous leveling of pressure in the case of a manual interruption of the
cycle, alarm or blackout.
Action: automatically restores atmospheric pressure in the sterilization chamber.
– Integrated system for evaluating the sterilization process
Provides continuous verification of the sterilization process parameters entirely managed by microprocessor.
Action: in case of anomaly, immediately interrupts the program and generates alarms.
– Monitoring of the sterilizer's operation
Provides real-time oversight of all significant parameters when the machine is on.
Action: in case of anomaly, generates alarm messages with possible interruption of the cycle.
