For Repair or Replacement
For many amperometric sensors, the measuring range deviates from the standard measuring
range (default value) of the controller. When repairing or replacing the controller these values
may have to be corrected or adjusted. For this purpose, the controller’s measuring range values,
which are documented in the individual operating instructions, must be checked and modifi ed,
if required.
To do so, the respective controller must be adjusted to the measuring range of the sensor. The
procedure is described in the individual operating instructions for the controller. The respective
setting values with regard to controller/sensor are listed in the table below.
For the measured variable “Inductive conductivity” it may be required to adjust the sensor type
when repairing or replacing the controller D1C.
The exact procedure is described in the individual operating instructions for the controller. For an
exact assignment and designation of the individual operating instructions, please see the list
“further applicable documents” in the annex of the present instructions.
