Fault: Calibration of pressure transducer 3 fails (PEEP).
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 PEEP pressure transducer E2-potentiometer
memory.
Description: CON is responsible for communication and initiating the PEEP pressure
transducer 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 PEEP pressure transducer failed.
Description: The system pressure is zero during offset calibration of the PEEP
transducer E2-potentiometers. The PEEP 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 PEEP transducers
E2-potentiometers.
Displays on Control panel:
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 alt. PC 1781 (PEEP).
2. Replace PC 1730 Control.
Refer to CAL_PRS_OFFSET_INIT_FAIL (...00 0A) above.
Fault: The second offset calibration of the PEEP pressure transducer failed.
Description: The offset adjustments of the PEEP pressure transducer E2-
potentiometers is repeated but with a negative offset (-25 cm H2O or -10 cmH2O with
PC1750C) to enable measurement of negative pressures.
Displays on Control panel:
The Tidal Volume display shows the target: 2500 (1000 with PC 1750C).
The Exp. Tidal Volume display shows the adjusting transducer value in 1/100 cmH2O.
What to do: Refer to CAL_PRS_OFFSET_FAIL (...00 0B) above.
Refer to CAL_PRS_OFFSET_INIT_FAIL (...00 0A) above.
