Error Error message text
06 No sensor detected,
please check the
connection.
07 Check the mechan‐
ical state of the
sensor. Glass
breakage is pos‐
sible.
08 The checkout time
was transgressed.
09 The mA input current
is too high.
10 The mA input current
is too low.

Cause
Measuring cable con‐
nection disconnected.
No sensor is con‐
nected.
Cable faulty or not con‐
nected.
Sensor is suspended in
the air.
Diaphragm glass
broken.
[Control] menu,
In the
the set control variable
has exceeded the
threshold for a longer
time than the checkout
time control variable.
The current is greater
than the maximum per‐
mitted current of 23
mA.
The power circuit is
disconnected.
Remedy
Check the correct connection of the
measuring cable connection.
Connect the sensor correctly.
Install the sensor correctly in the
bypass fitting.
Replace sensor.
Check the reason for the broken glass
e.g. solids, too high a flow velocity.
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 disconnected or
the point of injection blocked.
Check the origin of the current.
Check the raw value in mA in the Infor‐
mation menu by pressing
value is >23 mA, then it is not a correct
sensor signal. Replace the sensor with
a new sensor.
Check the 2-wire connection between
the sensor/transmitter and controller
and check the raw value in mA by
pressing . If the value is 0 mA, then
the connection is disconnected.
. If the
