Cause
The sensor input of
Channel 1 or 2 is used in
2-wire connection mode,
but the signal is an active
signal carrying voltage.
The chemical in tank 1 is
used up.
The chemical in tank 2 is
used up.
The chemical in tank 3 is
used up.
This liquid cannot be
measured with this
sensor.
This liquid cannot be
measured with this
sensor.
One or more correction
variables have been
incorrectly entered and/or
the correction variable
has been incorrectly
recorded.
The external power
supply has been incor‐
rectly designed or is
faulty.
The connection elements
have been incorrectly
installed or are faulty.
The connection cable has
slipped out of the socket.
Connection problems
between the main and
extension module.
System components have
failed.
Remedy
Use a multimeter to check the measuring
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 connec‐
tion is not shown on the enclosed terminal
assignment diagrams.
Top up the corresponding chemical.

Use a suitable sensor, if necessary.
Use a suitable sensor, if necessary.
Check the correction variable and all con‐
nected components.
Return the external power supply to its cor‐
rect working order.
Return the controller to the factory for
inspection.
Check the connection cable and tighten.
Return the controller to the factory for
inspection.
Return the controller to the manufacturer
for inspection.
