Fault: Internal program error.
Description: Unrecoverable error has occurred and the CON software has restarted.
The processor load has reached its maximum limit (red_error).
What to do: Report to EM-HSC.
Description: Tells what version of CON and MEA software the system contains.
This diagnostic log is written every start-up of system (Off to Standby/On).
AB CD tells the MEA version label in decimal form.
EF GH tells the CON version label in decimal form.
Fault: Inspiratory fresh gas flow transducer is not working.
Description: The measured fresh gas flow is much greater than the set fresh gas
flow. Refer to diagnostic DIAG_FGAS_FAILURE_NO_LONGER (201).
This diagnostic log cannot appear in non-rebreathing ventilation modes.
This diagnostic log may appear now and then, but most of the time the software
corrects the problem automatically by doing an extra zeroing of the inspiratory fresh
gas flow transducer.
What to do: If appearing repeatedly:
1.
Run a PuC to calibrate the inspiratoty fresh gas flow transducer.
2.
Check that the inspiratory fresh gas valve tube is correctly mounted.
3.
Check that the inspiratory fresh gas valve works properly by measure the
fresh gas flow with a calibration manometer on the auxiliary outlet.
4.
Replace the inspiratory fresh gas flow transducer.
5.
Replace PC 1748/1797 Fresh gas flow.
6.
Report to EM-HSC.
The measured fresh gas flow (1/10 ml/s) is presented in sub data in hexadecimal form.
Description: This diagnostic log follows the diagnostic log DIAG_FGAS_FAILURE
(200) or DIAG_FGAS_TRANSDUCER_FAILURE (204) when the faulty situation has
been solved by software.
The set fresh gas flow (1/10 ml/s) is presented in hexadecimal form.
Fault: PC 1752 Position sensor at the fresh gas pressure container is not working
properly.
Description: The fresh gas step motor is fully open, but no signal from the position
sensor is detected. A backup filling of the fresh gas pressure container has been
made.
This diagnostic log may appear now and then without impact on the functionality.
What to do: If appearing repeatedly:
1.
Run a PuC to detect leakage and to calibrate the inspiratory fresh gas flow
transducer.
2.
Adjust the position of the PC 1752 Position sensor.
The time (ms) since last bellows filling is presented in hexadecimal form.
