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

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

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)
