25
The software has failed to detect a need to
pump water within 90 seconds of the start of the
cycle.
% Blown thermal fuse (check the following)
o Pump delivery
o Steam generator triac
% Steam generator fault (open circuit).
26
(i)
The sterilization phase has failed to start within 3
minutes of the cassette reaching the sterilization
temperature. Note: for rev 4.xx software only,
the unit has to fail on 3 consecutive cycles
for CF26 to display.
% Calibration imbalance (boiler
thermocouple to chamber
thermocouple)
% Poor pump delivery
% Sticking solenoid valve
% Check Vref is 2.520V± 0.001V
26
(ii)
The sterilization phase has failed to start within 3
minutes of the cassette reaching the sterilization
temperature. Note: the unit has to fail on 3
consecutive cycles for CF26 to display.
“Cycle Interrupted” displayed for the first 2
occurrences.
% Calibration imbalance (validation
thermocouple to chamber
thermocouple)
% Poor pump delivery
% Sticking solenoid valve
% Check Vref is 2.520V± 0.001V
(rev 6.xx ONLY)
27
The temperature of the steam generator failed to
drop bellow a set-point temperature (150°C or
165°C) in a timeout period or during a panic
pump situation.
% Poor pump delivery
% Failed water sensor (level)
% Contaminated steam generator
28
The cassette pressure rose above a ceiling
value.
% Pressure measurement failure.
% Calibration imbalance (pressure
transducer to chamber thermocouple)
% Sticking solenoid valve (closed)
% Failed solenoid coil
% Blocked cassette exhaust duct
% Obstructed exhaust tubing (kink)
% Blockage or restriction in pressure
transducer tube
