Fault: "Checking pressure transducers" test failed during PuC.
Description: A comparison of each pressure transducer is performed.
The first step is to build up pressure in the system with a fresh gas flow of 18 l/min until
the Insp. pressure transducer measures 10 cmH2O where the flow is shut off.
Acceptance tolerance 10 ±4 cmH2O.
The second step is to build up pressure in the system with a fresh gas flow of 18 l/min
until the Insp. pressure transducer measures 20 cmH2O where the flow is shut off.
Acceptance tolerance 20 ±4 cmH2O.
The last step is to evacuate the system during 2 s by opening the PEEP valve.
Acceptance tolerance 0 ±4 cmH2O.
MV1-MV5 are opened during all steps.
Note: All the diagnostic log 266, 267, 268 and 269 is shown in log to see witch
pressure transducer that is out of "acceptance tolerance" when the "Check of pressure
transducers" in PuC fails.
Refer to section "If the Pre-use check fails" in this chapter and to information regarding
"Checking pressure transducers" in chapter "Service procedures", section "Pre-use
check".
What to do:
1. Perform a Calibration.
2. Check for leakage in the system, i.e. check that pressure transducer tubes
are properly connected.
3. Replace PC 1750 Transducer (or the concerned PC 1781).
The pressure measured (1/100 cmH2O) by the Exp. pressure transducer is presented
in sub data in hexadecimal form.
Fault: Refer to DIAG_PUC_QCHECK_EXP_TRANSDUCER (266)
The pressure measured (1/100 cmH2O) by the Insp. pressure transducer is presented
in sub data in hexadecimal form.
Fault: Refer to DIAG_PUC_QCHECK_EXP_TRANSDUCER (266)
The pressure measured (1/100 cmH2O) by the PEEP pressure transducer is
presented in sub data in hexadecimal form.
Fault: Refer to DIAG_PUC_QCHECK_EXP_TRANSDUCER (266)
The pressure measured (1/100 cmH2O) by the Man. pressure transducer is presented
in sub data in hexadecimal form.
