Free Chlorine //
Malfunction and Maintenance
Only applies to sensors with digital internal signal processing:
Fault Possible cause Action
Green LED
Flickering or no light
Too low voltage -> faulty power supply Establish correct power supply
Sensor defective Send in sensor to be checked / over-
hauled
Orange LED
Continuous light
Incorrect polarity of the sensor signal
-> displayed output signal must be
multiplied by -1 Service the sensor according to chapter
6.2 or send in sensor to be checked /
overhauled
Underdrive See chapter 6.3.1, section Underdrive
Regular flashing Sensor is overloaded -> chlorine con-
centration too high Check system, rectify faults, calibrate or
service sensor if necessary
Overdrive See chapter 6.3.1, section Overdrive
6.3.2 Special Troubleshooting on the Sensor
If the electrode finger turns shiny silver or white, the sensor must be overhauled by the manufacturer. Brown-grey discolou-
rations are common.
Tightness test of mem-
brane cap 1. Carefully dry the outside of the membrane cap to be tested
2. Prepare the membrane cap for installation according to the operating instructions and fill with
electrolyte
3. If necessary, dry the membrane cap again on the outside
4. Screw the membrane cap slowly and carefully onto the sensor according to the operating
instructions
5. When screwing on the membrane cap, check whether electrolyte gel escapes through the
membrane
-> If a drop flow forms on the membrane, it is defective and a new membrane cap must be used.
The formation of a small meniscus can be tolerated since the membrane is hydrophilic.
-> Check whether the reference electrode has been damaged by the exchange between measuring
medium and electrolyte. If it is no longer in perfect condition, send in the sensor for inspection.
Carefully check whether the electrolyte is escaping through the membrane
or if it is sealing properly at the intended points; repeat the tightness test
if necessary.
