After opening the door on the dirty side, even after closing it and it being
locked and sealed, the door on the clean side can be opened only after
performing a complete sterilization cycle.
If cycle failed, the front door only can be opened.
After test cycle, the front door only can be opened.
A door cannot be opened at the end of the cycle if the chamber temperature is
higher than the preset final temperature.
The electronic circuitry and software programming of the programmable control system
are designed to operate 10 sterilization programs. Three programs are intended for un-
wrapped instruments, four for wrapped instruments and packs, three for slow exhaust
pressure cycles. In addition, there are two test programs: Bowie & Dick Test and the
Leakage Test.
The control system of the sterilizer is based on microcomputer technology, ensuring a
highly reliable and safe operation. The computerized control unit ensures a fully
automatic operation through the entire cycle; hence, after setting the pre-selected
parameters and starting the operation, no further operator intervention is necessary.
The autoclave has an automatic shutdown system. If no buttons or switches are
operated for four hours, it will go into SLEEP MODE and a LED lights up (blinking every
second), indicating that the system is in the SLEEP MODE.
The selected program, the main phases of the cycle and the status of the machine are
controlled and displayed on digital readouts. For process documentation, the important
information concerning operation is printed.
The system is equipped with two temperature sensors,four pressure transducers, five
pressure gauges, and safety devices having the following functions:
The temperature sensors:
1. In the drain – (control)
2. In the condensate line(double) – (control, monitoring, and printout)
The pressure transducers measure:
1. Chamber pressure – (control, display, and printout)
2. Jacket pressure – (control and monitoring)
3. Door 1 gasket pressure – (control and monitoring)
4. Door 2 gasket pressure – (control and monitoring)
