3.9.2 Maintenance tasks
Testing the safety valve on the steam generator (X series only)
• Connect the PC.
• Open the Systec service software (see chapter 6, “Systec service
software”).
• Call up the window for setting outputs via “I/O”.
• Click on Go to manual mode.
• Activate the WaterPump output.
The steam generator is now flooded.
• Check the steam generator pressure in the control panel display:
The safety valve must open when P
max
is exceeded.
Testing the safety valve on the sterilisation chamber
The functionality of the safety valve must be safeguarded with external
aids.
The safety valve must open when P
max
is exceeded.
Alternative procedure for devices with steam generators:
• Unscrew the safety valve on the sterilisation chamber and replace it
with the safety valve on the steam generator.
• Follow the same procedure as used to check the safety valve of the
steam generator (see “Testing the safety valve on the steam generator
(X series only)”). Now observe the P
max
of the sterilisation chamber.
• After the test, move the safety valves back to their original position.
Alternative procedure (only for devices with support air supply):
Prerequisite: The compressed air supply is able to generate the necessary
pressure.
• Attach an external manometer to the sterilisation chamber as a
reference.
• Bridge the pressure reducer for the compressed air.
• Activate the output in the Service -> Manual output set
menu to allow compressed air to flow.
• Check the reference pressure display:
The safety valve must open when P
max
is exceeded.
