39
Micro-switch M2 36B:
PT1 temperature probe alarm
This is triggered when chamber temperature probe 39 in the steriliser is disconnected or
faulty.
The steriliser shows this alarm during operation when the probe detects a temperature of
less than 3°C.
• Check the connection of chamber temperature probe 39 to connector CN12.
• Replace the probe if faulty.
• Check temperature setting following the instructions shown in the STERILISATION
TEMPERATURE BAND ALARM section.
Drain alarm
This indicates that the pressure did not drop to the correct predetermined value during
draining.
This alarm is displayed during the draining phase of a cycle when the pressure did not drop
to the correct value in the expected time.
• Check solenoid valve EV6.
• Check solenoid valve EV3.
• Check operation of vacuum pump 41.
• Proceed as shown for the FRACTIONED VACUUM ALARM.
Misalignment alarm
This indicates that the temperature in chamber 09 does not correspond to the theoretic
steam temperature.
The steriliser displays this alarm during the sterilisation phase when the temperature in
chamber 09 and the theoretic steam temperature differ by more than 2°C.
This alarm could be generated by incorrect temperature and pressure values.
• Check the temperature and pressure settings of the steriliser following the
instructions shown in the STERILISATION TEMPERATURE BAND ALARM section.
