Cause Remedy
05 There is a calibra‐
tion error
With amperometric anal‐
ysis (e.g. chlorine): the
calculated reference
value deviates too much
from the real value or
the sensor value.
With amperometric analysis
(e.g. chlorine): Check the cor‐
rectness of the reference
method, e.g. DPD1
With pH and ORP: the
buffers used differ from
the nominal value, are
outdated or watered
down
With pH and ORP: replace the
buffer with new buffer
06 No sensor is fitted Coaxial cable connec‐
tion disconnected
Check the correct connection
of the coaxial cable connection
No sensor is connected
07 Check the
mechanical state
of the sensor.
Glass breakage is
possible.
Membrane glass broken Replace sensor
Check the reason for the
broken glass e.g. solids, too
high a flow velocity
08 The checkout time
was infringed
In the [Control] menu,
the set control variable
has exceeded the
threshold for a longer
time than the checkout
time control variable
The control section needs a
longer time to regulate itself
than the selected checkout
time.
The control section needs a
greater control variable
threshold to regulate itself than
the selected one.
The metering chemical is
empty or has a too low/high a
concentration
The metering line is discon‐
nected or the point of injection
blocked.
09 The mA input cur‐
rent is too high
The current is greater
than the maximum per‐
mitted current of 23 mA
Check the origin of the current.
