Alarm Information
Troubleshooting Methods
1
LED calibration abnormal or
failure (E12, E13, E14)
1.Confirm whether the deionized water has been contaminated, if so,
replace the deionized water and then run the cleaning procedure;
2.Perform the cleaning process, clean the reaction cell and measuring
cell, and then re-calibrate the light path to check whether the fault is
eliminated;
3.Perform the deep cleaning process, deeply clean the reaction cell and
measuring cell, and then re-calibrate the light path to check whether the
fault is eliminated;
4.If the fault still occurs, contact the after-sales personnel to confirm the
fault and repair it.
2
Measurement results higher than
the upper range limit/
measurement results lower than
the lower range limit (W17, W18)
1.The measurement result exceeds the selected measurement range,
re-select the measurement range according to the concentration of
actual water sample. If it is higher than the upper limit of measurement,
choose a higher range of measurement; if it is lower than the lower
measurement limit, select a lower measurement range.
3
Unstable LED light source (W0,
W21)
1.Confirm whether the deionized water has been contaminated. If so,
replace the deionized water and then run the cleaning procedure;
2.Perform the cleaning process, clean the reaction cell and measuring
cell, and then re-calibrate the light path to check whether the fault is
eliminated;
3.Perform the deep cleaning process, deeply clean the reaction cell and
measuring cell, and then re-calibrate the light path to check whether the
fault is eliminated;
4.Use the system’s diagnostic function, enter the light source and
detector option, turn on the LED and observe whether the PD (photo
diode) detection voltage is stable;
5.If the fault still occurs, contact the after-sales personnel to confirm the
fault and repair it.
