Troubleshooting

Troubleshooting must take account of the whole measuring system. The measuring system

consists of

Measurement/control

device

2) Electrical leads and connectors

3) In-line probe housing and hydraulic connections

Sensor

The possible causes of failure listed in the following table primarily refer to the sensor. Before

commencing troubleshooting please ensure that the operating conditions are met:

a) Chlorine content lies within the corresponding measurement range of the sensor

b) Constant pH in the range 6.5 - 9.5

c) Constant temperature in the range 4 - 45 °C

d) Conductivity: 0.03 - 40 mS/cm

e) Flow: 30 - 60 l/h

The sensor simulator (DULCOMETER

Simulator order no. 1004042) is recommended for locating

a controller malfunction. You will ﬁ nd a detailed description of troubleshooting of the controller in
the operating instructions of DULCOMETER

D1C, chlorine.

If the value measured by the sensor differs signiﬁ cantly from that of the DPD method you need to

ﬁ rst consider all possible malfunctions of the DPD photometric method. If necessary, repeat the
DPD measurement several times.

Fault

Sensor can not be
calibrated. Measured
value

greater

than

DPD-measurement

Sensor can not be
calibrated. Measured
value

smaller

than

DPD-measurement

Possible Cause

Run-in time too short

Membrane cap damaged

Interfering substances in sample
water

Short-circuit in signal lead

Distance between membrane
and electrode too great

DPD chemicals spent

pH-value < pH 6.5

Run-in time too short

Deposits on membrane cap

Flow rate of sample water too low

Air bubbles on the outside of the
membrane

Interfering substances in sample
water (surfactants, oil, alcohols,
corrosion inhibitors)

Value substantially exceeds
measurement range

Deposits (carbonate, manganese,
iron oxide) have blocked
membrane

pH-value > pH 9.5

No electrolyte present in
membrane cap

Remedy

See “Run-in period”

Replace membrane cap, run in

sensor and calibrate

Examine sample water for in ter-

fer ing substances and remedy

Locate and eliminate short

circuit

Screw the membrane cap tightly

onto the electrode shaft

Use new DPD chemicals,

repeat calibration

Raise pH-value (6.5-9.5)

See “Run-in period”

Remove deposits, see “Main-

tenance”. Replace membrane
cap, run-in sensor, calibrate

Correct ﬂ ow rate

Remove air bubbles by tapping

and increase ﬂ ow, if required,
within the permitted range

Confer with ProMinent

Replace membrane cap,

run-in sensor, calibrate

Replace membrane cap,

run-in sensor, calibrate

Lower the pH value

(pH 6.5-pH 9.5)

Fill membrane cap with new

electrolyte see “Assembly”,
“Run-in period” and “Cali bra tion”
