FAILURE
Sub data:
... 00 0A CAL_PRS_OFFSET_INIT_FAIL
... 00 0B CAL_PRS_OFFSET_FAIL
... 00 0C CAL_PRS_OFFSET2_INIT_FAIL
Fault: The second offset calibration of the INSP pressure transducer failed.
Description: The offset adjustments of the INSP 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 Tidal Volume display shows the target value: 170 (A/D value for 25 cmH2O).
The Exp. Tidal Volume display shows the adjusting transducer value.
Values displayed is converted from cmH20 to corresponding A/D-value.
What to do: Refer to CAL_PRS_OFFSET_FAIL (... 00 0B) above.
Fault: Calibration pressure transducer 4 fails (MAN).
Description: Refer to information regarding "Calibrating pressure transducers" in
chapter "Service procedures", section "Calibration".
CON is responsible for calibration of this transducer.
Fault: Failed to write data to the MAN pressure transducer E2-potentiomerter memory.
Description: CON is responsible for communication and initiating the MAN pressure
transducers E2-potentiometer over the I2C bus.
What to do:
1. Replace PC 1750 Transducer.
2. Replace PC 1730 Control.
Fault: The first offset calibration of the MAN pressure transducer failed.
Description: The system pressure is zero during offset calibration of the MAN
pressure transducer E2-potentiometer. The MAN pressure transducers E2-
potentiometers are adjusted during calibration until the transducer value is close to
zero.
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 display shows the pressure measured by the INSP pressure
transducer until a stable pressure is reached.
The Preset O2 Conc. 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: 0
The Exp. Tidal Volume display shows the adjusting transducer value in 1/100 cmH2O
What to do:
1. Replace PC 1750 Transducer.
2. Replace PC 1730 Control.
Refer to CAL_PRS_OFFSET_INIT_FAIL (... 00 0A ) above.
