DANGER
If an error message is displayed during the sterilization
process, the load must be considered non-sterile.
The program control is equipped with a sophisticated error management system. If
an error occurs during program execution, an error message is shown in the Cycle
display (18) or the Current values display (15). Each error message is also
recorded on the batch printer printout.
If an error occurs:
♦
Press the Acoustic signal key (22) and the START/STOP key (20)
concurrently.
This will interrupt the program cycle. The sterilizer is returned to a safe state.
♦
Before restarting the program, troubleshoot the problem (see Table 2).
