Summary

Troubleshooting Guide for the CLF10 sc and CLT10 sc Chlorine Analyser

Answer
Below is a list of common problems that are experienced with the CL10. There causes and corrective action is also discussed as well as the preventative maintenance to avoid these issue in the future.
Problem Cause Corrective action Preventative Actions
Controller does not recognize the chlorine sensor
 
Incorrect wiring
 
Review manual and follow start up procedures Review manual and follow start up procedures
Outdated controller software Update controller software to the latest version available Always update software whenever installing new equipment onto an existing platform
The chlorine reading displays dashes
(---) at analyser
start-up
Powering and possibly internal failure of the chlorine sensor Check the LED’s located on the top of the sensor for diagnostics of the working condition of the sensor (Tip: best to view LED from the top of the sensor) Refer to the manual – Sensor LED’s
Sensor has not been conditioned properly Condition the sensor according to the manual Refer to manual…
Check the raw signal value (Menu-Sensor Setup, Diag/Test, Signals)  (Tip: the chlorine signal value needs to show negative mV after conditioning) Allow for up to 24 hours for complete conditioning in a constant flow of a chlorinated water sample.
No chlorine in sample Check the chlorine level of the sample using a DPD grab sample method Always verify presence of chlorine before troubleshooting
Low flow rate or absence of sample flow Check your flow rate – flow sensor LED will on Refer to the manual
Air bubbles in electrolyte Refill the electrolyte making sure not to introduce air bubbles into the electrolyte Keep electrolyte bottle upside-down.
Fill the electrolyte in one squeeze – refer to the manual
The chlorine sensor will not hold the calibration point Bubble/air in the electrolyte
 
 
 
Refill the electrolyte solution making sure not to entrain air bubbles and then replace the membrane  
Damaged membrane Change sensor membrane cap Avoid physically touching the membrane surface
Oxidized cathode tip Polish the electrode tip None
Electrolyte is deteriorated – improper storage, expired, or worn out through prolonged usage time Replace electrolyte Proper storage of electrolyte and follow electrolyte replacement interval guidelines
Chlorine measurement value fluctuates Air bubbles in electrolyte
 
Replace the electrolyte making sure not to entrain air bubbles Always try to fill the electrolyte with one steady squeeze
Oxidized cathode sensor tip Polish the electrode tip  
Inconsistent flow rate Adjust the flow to proper levels Install sample conditioning kit
Inconsistent pH  Add pH option and configure Calibration Watch feature Choose more proper sampling point
pH is too high Install the acidification unit Install the acidification unit
Sample conductivity is too low Change application Examine the application prior to purchasing instrumentation
