Sub data:
Fault: The second offset calibration of the MAN pressure transducer failed.
Description: The offset adjustments of the MAN pressure transducer E2-
potentiometers is repeated but with a negative offset (-25 cmH2O or -10 cmH2O with
PC1750C) to enable measurement of negative pressures.
Displays on Control panel:
The Fresh Gas Flow digit display shows the pressure measured by the INSP pressure
transducer until a stable pressure is reached.
The Preset O2 Conc. digit display shows the pressure measured by the EXP pressure
transducer until a stable pressure is reached.
The Minute Volume display shows the pressure measured by the PEEP. pressure
transducer until a stable pressure is reached.
The Tidal Volume display shows the target value: 2500 (1000 with PC 1750C).
The Exp. Tidal Volume display shows the adjusting transducer value.
What to do: Refer to CAL_PRS_OFFSET_INIT_FAIL (... 00 0A ) above.
Refer to CAL_PRS_OFFSET_INIT_FAIL (... 00 0A ) above.
Fault: The gain calibration of the MAN pressure transducer failed.
Description: The drive gas regulates a stable pressure of first 17 cmH2O and then to
20 cmH2O, with the already calibrated PEEP pressure transducer as reference, during
the gain calibration of the MAN pressure transducer.
The MAN pressure transducers E2-potentiometers are adjusted during calibration until
transducer value is close to the system pressure.
The timeout for calibration is 64 attempts or 30 seconds to adjust MAN pressure
transducers E2-potentiometers.
Displays on Control panel:
The Fresh Gas Flow digit display shows the pressure measured by the INSP pressure
transducer until a stable pressure is reached.
The Preset O2 Conc. digit display shows the pressure measured by the EXP pressure
transducer until a stable pressure is reached.
The Minute Volume display shows the pressure measured by the PEEP pressure
transducer until a stable pressure is reached.
The Tidal Volume display shows the reached stable system pressure (target value).
The Exp. Tidal Volume display shows the adjusting transducer value in 1/100 cmH2O
What to do:
1. Check / replace manual breathing bag.
2. Replace PC 1750 Transducer alt. PC 1781 (MAN).
3. Replace PC 1730 Control.
4. Replace Drive gas module.
Fault: Stable pressure in the system is not reached when calibrating the pressure
transducers.
Description: Refer to information regarding "Calibrating pressure transducers" in
chapter "Service procedures", section "Calibration".
