overloaded.
17 The level in the
storage tank 1 is too
low.
18 The level in the
storage tank 2 is too

Cause
The sensor input of
Channel 1 or 2 is used
in 2-wire connection
mode, e.g. together
with chlorine sensor
CLE3.
The polarity was not
noted or there is a
short circuit between
the two poles.
The sensor input of
Channel 1 or 2 is used
in 2-wire connection
mode, but the signal is
an active signal car‐
rying voltage.
The chemical in
storage tank 1 is used
up.
The chemical in
storage tank 2 is used
up.
The chemical in
storage tank 3 is used
up.
This liquid cannot be
measured with this
sensor.
This liquid cannot be
measured with this
sensor.
Remedy
Check the polarity against the terminal
diagram.
Make sure that the two wires do not
touch (shorten the bared length, use
insulated end sleeves, use heat-shrink
tubing).
Use a multimeter to check the meas‐
uring signal. If it is an active / driven
signal (voltage is measurable), then the
type of connection has to be selected
for active signals; refer to the terminal
diagram in the operating instructions.
This type of connection is not shown on
the enclosed terminal assignment dia‐
gram.
