Error logs
Display message Status
Sensorline Error
Sensor line disconnection of the zirconia oxygen sensor was detected.
TC-line Error Temperature control line disconnection of the zirconia oxygen sensor was detected.
Sub temp. Error Line disconnection of the thermocouple for combustion control was detected.
Warm-up Error
Warm-up was not completed within the warm-up monitoring time (45 minutes).

Warm-up is properly completed if the heater temperature of the zirconia oxygen sen-
sor becomes the control temperature (800°C) ± 1°C and stable for one minute.
Cell temp. Error Heater temperature exceeds the specified range (800°C ± 70°C)
Span gas Error

The concentration of the calibration span gas being supplied is not stable.
(In a discrimination treatment of stability, the error of ± 0.2% or more compared to the
value in the previous treatment continues.)
Zero gas Error

The concentration of the calibration zero gas being supplied is not stable.
(In a discrimination treatment of stability, the error of ± 0.2% or more compared to the
value in the previous treatment continues.)
Span cal. Error
Span calibration failed. (Calibration factor could not be determined.)
Zero cal. Error Zero calibration failed. (Calibration factor could not be determined.)
Sensor Error,
A/D data Error An error was detected in the A/D conversion of oxygen concentration value of the zirco-
nia oxygen sensor. (260 mV or more, –50 mV or less)
