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
