Explanation
Description up to 15 text characters Designation for the input
Operating mode linear scaling,
temp. measurement,
pH-value measurement,
conductivity measure-
ment,
free chlorine
pH/T-compensated Type of measuring
linear scaling: Standard signals (for
IN 11/12 and resistance potentiometer
a
) with lin-
ear measurement characteristic line or customer-
specific linearization
For standard signals the scale start point, scale
end point and unit must be specified.
Temp. measurement: Measurement made with
a
resistance thermometer
The type of sensor is selected in the "Signal type"
configuration item. The unit for the temperature is
specified in the "Basic Settings" menu.

pH value, conductivity, and free chlorine: The
values measured by the individual analysis sen-
sors are received in the form of a standard signal.
Outside factors affecting the individual analysis
process variables are compensated. It is thus
necessary to make appropriate compensation
settings in the configuration of the universal in-
put.
Signal type IN 6/11/12:
0 to 20 mA
4 to 20 mA
20 to 0 mA
20 to 4 mA
Type of sensor connected
Correct scale settings are required for the stan-
dard signals
