(i)
2.xx only
The software has detected the filtered steam
generator temperature 6°C less than the chamber during the sterilizing phase of a cycle.
• Contaminated steam generator
• Failed steam generator
• Calibration imbalance (boiler to
chamber)
• High pump flow
8
(ii)
The software has detected the Validation
Thermocouple temperature to be 5°C less than the chamber temperature during the sterilizing
phase of a cycle.
• Calibration imbalance (validation
thermocouple to chamber thermocouple)
• High pump flow
• Blocked cassette exhaust duct • Sticking solenoid valve
Check Vref is 2.520V± 0.001V (all software
revisions OTHER THAN revision 6.xx)

During conditioning (purging), the cassette
temperature has failed to drop to115°C during
the Unwrapped or Wrapped Cycle OR the temperature has failed to drop to 110°C during
the Rubber and Plastics Cycle.
• Blocked cassette exhaust duct • Obstructed exhaust tubing (kink) • Sticking solenoid valve (closed)
• Failed solenoid coil
11
The cassette temperature has failed to drop to
102°C within a timeout period of the end of a
cycle during venting.
• Blocked cassette exhaust duct • Obstructed exhaust tubing (kink) • Sticking solenoid valve (closed)
•
Failed solenoid coil
12
This indicates a problem with the temperature
measuring system.
• Broken or faulty thermocouple • Circuit failure on PCB
13
Not used
14
The steam generator temperature is above
171°C during the sterilization phase of a cycle.
• Poor pump delivery • Calibration imbalance (boiler
thermocouple to chamber thermocouple)
• Failed water sensor (level)
