Explanation
Designation up to 20 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 transmitter
a
) with linear
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:
0to20mA
4to20mA
20 to 0 mA
20 to 4 mA
Type of sensor connected
Correct scale settings are required for the stan-
dard signals.

.
For 400 Ω and 4000 Ω, a customer-specific lin-
earization must be configured.
