Chlorine measurement (PoolManager
®
PRO only)
Type of problem
Potential cause of the
problem
Remediation of the
problem
DPD measurement and
unit display show
different values
Calibration erroneous or
was a long time ago
Perform a new
calibration.
Measurement water feed
to low or turned off
(cleaning balls not
rotating sufficiently)
Check measurement
water feed, then perform
new calibration
Measurement water feed
not consistent
Ensure consistent
measurement water
feed , then perform new
calibration
DPD chemicals replaced
or expired chemicals
used
Use new DPD
chemicals, perform new
calibration
Film (such as calcium)
on the gold electrode
Cleanse the gold
electrode with a soft
towel and diluted
hydrochloric acid. After
cleaning, observe the
time it takes for the
measuring cell to
stablise.
Calibration failure in pH
calibration
Erroneous entry of
calibration values
Repeat calibration
Chlorine level in the
water too low during
calibration
Perform new calibration
with a chlorine level
close to the setpoint
Glass electrode or gold
electrode in the chlorine
measuring cell too old or
defective
Replace glass electrode
or
gold electrode
Measurement amplifier
defective
Device has to be
replaced
Chlorine measurement is
unstable
Measurement water feed
too low or turned off
Secure measurement
water feed such that the
balls rotate evenly
again.
Chlorine control / chlorine dosing
The unit shows a dosing
output of 0% although
there is a deviation
between actual value
and setpoint
Dosing is blocked by an
alarm (flow, level, or
dosing alarm)
Remediate alarm cause
Acknowledge alarm
Start delay still running
Wait for end of start
delay
The dosing pump
continues to run despite
the unit showing a
dosing output of 0%
Fuse on the dosing
pump is burnt
Replace fuse
(2AT)
Dosing relay defective
Replace the respective
relay
Dosing pump defective
Replace the dosing
pump
Dosing pump is running,
but there is no chlorine
correction
Container is empty
Replace maintenance
product
Dosing pump has sucked
in air and is no longer
dosing
Remove air from dosing
head
Dosing pump has sucked
in air and is no longer
dosing
Remove air from dosing
head
Chlorine value fluctuating
around the setpoint
Chlorine control dosing
output is too high
Set a higher value for the
p-range, which will lower
dosing output.
Reducing the minimum
switch-on time also
hinders overdosage.
Chlorine value deviates
from setpoint over a
Chlorine control dosing
output is too low
Set a lower value for the
p-range, which will
longer period of time
increase dosing output.
An increase in minimum
switch-on time will result
in the setpoint being
approached more
quickly.
