Troubleshooting
Trouble
No display despite
power supply and circuit
breaker are OK
Incorrect indication of
pH value
Incorrect indication of
Turbidity value
Incorrect indication of
PAH value
Fluctuations of readings → Possibly caused by air bubbles. Check the sampling line. Check
No data log
No historical trend curve
Increased pump
temperature
Possible Cause →Action
→The display is defect →Reboot, repair, or exchange the display.
→ Try to clean the sensor and chamber manually.
→ Try to validate the pH Sensor.
→ Change the pH Electrode.
→ Try to clean the sensor and chamber manually.
→ Try to validate the Turbidity Sensor.
→ Water coloration might restrict light passing through the sample.
Try to minimize the water coloration.
→ Check the wiring from the Turbidity sensor to the Turbidity
Analyzer.
G6110: Check/clean the sensor, bushing, and chamber thoroughly.
G6111: Check/clean the sensor and chamber thoroughly.
→ Check expiration date of PAH sensor certificate
→ Validate the PAH Sensor
→ Check/remove bubbles in calibration liquid.
→ Check calibration liquid expiration date and temperature
→ Do not expose PAH calibration liquid to UV light for more than a
few minutes since UV light degrades PAH molecules
that the de-bubbler is functioning.
→ Wait for the trend to generate the curves.
→ Check if the SD card is in position.
→ If yes, check the SD card's lock mode.
→ Replace the SD card if it is defect.
→ Pump/motor rotation is hard. Maybe water in bearing or foreign
material block pump → inspect motor and pump to identify reason
for blockage or other factors that stops the motor or pump from
rotating freely.
