3.3. SAFETY DEVICES
The sterilser is equipped with the following safety devices for which we provide a brief description of their function:
•
Mains fuses
(see data in summary table)
Protection of the whole device against possible failures of heating elements.
Action: power supply interruption.
•
Electronic circuit protection fuses
(see data in summary table)
Protection against possible failures of the primary circuit of the transformer and of low voltage users.
Action: interruption of one or more low voltage circuits.
•
Thermal circuit-breakers on mains voltage windings
Protection against possible overheating of pump motors and of transformer primary winding.
Action: temporary cut-off (until cooling) of the winding.
•
Safety valve
Protection against overpressure in the sterilisation chamber.
Action: release of the steam and restoration of the safety pressure.
•
Safety thermostat with steam generator manual reset
Protection against steam generator overheating.
Action: cut-off of the electricity to the steam generator.
•
Safety thermostat with chamber heating element manual reset
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: signalling of wrong door position.
•
Motor-driven 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 locking mechanism safety microswitch
Striker for the correct closing position of door locking system.
Action: signalling of failed or wrong operation of door locking mechanism.
•
Self-levelling hydraulic system
Plumbing system structure for the spontaneous levelling of the pressure in the case of a manual interruption of the cycle, alarm or blackout.
Action: automatic restoration of atmospheric pressure in the sterilisation chamber.
•
Integrated system for evaluating the sterilisation process
Continuous verification of the sterilisation process parameters entirely managed by microprocessor.
Action: immediate interruption of the program (in case of malfunction) and generation of alarms.
•
Steriliser operation monitoring
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.
