10. Statim 5000 Trouble-shooting – Cycle Faults
45
Cycle Fault #25
The software has failed to detect a need to pump
water within 90 seconds of the start of the cycle
The most probable cause is a blown thermal fuse due to
weak pump delivery and/or a contaminated steam
generator, or improperly connected steam generator
leads (loose or unconnected). If the steam generator
triac has failed, the thermal fuse may have also failed.
Verify steam generator resistance (could be failed open)
Cycle Fault #26
Software Revisions
R1xx, R2xx or R4xx
The sterilization phase has failed to start within 3
minutes of the cassette reaching the sterilization
temperature.
For software rev. R4xx CF26 is displayed when it
occurred in three consecutive cycles (Cycle
interrupted is displayed for the first two cycles).
Cycle Fault 26 counter is reset whenever a
successful cycle is completed.
This may be caused by improper boiler thermocouple
calibration, by a contaminated steam generator, by a
weak pump delivery or by a faulty solenoid valve.
Also verify Vref to be 2.520V± 0.001V
Cycle Fault #26
Software Revision
R5xx and R6xx
The sterilization phase has failed to start within 3
minutes of the cassette reaching the sterilization
temperature.
CF26 is displayed when it occurred in three
consecutive cycles (Cycle interrupted is displayed
for the first two cycles). Cycle Fault 26 counter is
reset whenever a successful cycle is completed.
This may be caused by improper validation
thermocouple calibration, by a weak pump delivery or
by a faulty solenoid valve.
For PCB other than rev 7.xx also verify Vref to be
2.520V± 0.001V.
Cycle Fault #27
The temperature of the steam generator failed to
drop bellow a set-point temperature (150°C or
165°C) in a timeout period
Several conditions may cause this: weak pump delivery
and/or out of water during a cycle, restriction to the
pump inlet tube or a defective water quality sensor
(sensor does not detect insufficient water in the water
reservoir) or a contaminated steam generator.
Cycle Fault #72
Software Revision
R5xx only
There is a communication error between the
microprocessor and the Temperature Adapter Board
(TAB).
Check the connection between the square
microprocessor and the Printed Circuit Board (PCB). If
an adapter board is used check the connection between
the adapter board and the PCB. Look for bent or broken
pins. Verify that Temperature Adapter PCB (TAB) is
properly inserted and secured on the main Statim PCB.
