6.2 Configuration of the display
This function is used to configure the representation of the input signal on the display.
Positive gradient:

Measured
value 1
Measured
value 2
The scaling determines the relationship between the in-
put signal and the display value. For linear behavior, two
measured values(inP) or display values(dSP) must be
defined. To achieve the best precision, these 2 points
should be selected at both ends of the display range.
Negative gradient:
Displayed
value 1

value 2
Measured

The coordinates of these two points can be entered di-
rectly using the keypad (scaling mode) or the measured
values are automatically adopted. Only the assigned dis-
play values need to be entered via the keypad (teach
mode).

Scaling mode (teach-in using known support points)
Configuration of input and display values is done manually using the soft-touch keypad at the
process display. This method is appropriate if the sensor-supplied signal values are known at
each extreme point of the process.
First measured value
Keypad entries from -19999 to 99999.
Display value for the first measured value
The value entered here will be displayed upon the input signal reaching the
first measured value. Ranging from -19999 to 199999
Decimal point dSP1
Positioning decimal point, applies to dSP1 and dSP2.
Second measured value
Keypad entries from -19999 to 99999.
Display value for the second measured value
The value entered here will be displayed upon the input signal reaching the
second measured value. Ranging from -19999 to 199999
Programming of input characteristic
For measured values without linear behavior, up to 11 interpolation points (measured and dis-
play values) can be defined. For programming access to other measuring or display points,
press and hold the button for 3 seconds after having programmed the display value assigned to
the 2nd point. The new values assigned to the measuring or display points are identified by the
messages [Inp xx] and [dSP xx], whereas xx represents the point number of (de 03 to 11).
Measured value xx
Ranging from -19999 to 199999
Display value assigned to measured value xx
The value entered here is displayed when the input signal has reached the
measured value xx which was entered in the previous step. Programmable
from -19999 to 199999.
To interrupt programming of measuring or display points and save the val-
ues already entered, press and hold the button for 3 seconds after having
entered the previous display value.
INFO
Mandatory to enter the measured or displayed values in ascending or descending order.

Teach mode (teach-in using measured support points)
The input values are read directly at the input at the time the signal is detected at any point in
the process. Displayed value configuration is done manually using the soft-touch keypad of the
process display. This method is appropriate if the signal values are known at each point but run-
ning the process at the conditions defined by these extreme points is not feasible.
First measured value
The input signal value is automatically adopted.
Display value for the first measured value
The value entered here will be displayed upon the input signal reaching the
first measured value. Ranging from -19999 to 199999
Decimal point dSP1
Positioning decimal point, applies to dSP1 and dSP2.
Second measured value
The input signal value is automatically adopted.
Display value for the second measured value
The value entered here will be displayed upon the input signal reaching the
second measured value. Ranging from -19999 to 199999

For measured values without linear behavior, up to 11 interpolation points (measured and dis-
play values) can be defined. For programming access to other measuring or display points,

The value entered here is displayed when the input signal has reached the
measured value xx which was entered in the previous step. Programmable
from -19999 to 199999.
To interrupt programming of measuring or display points and save the val-
ues already entered, press and hold the button for 3 seconds after having
entered the previous display value.
INFO
Mandatory to enter the measured or displayed values in ascending or descending order.

6.3 Configuration of the limit value outputs
Device can be ordered with max. 4 relay limit outputs. Configuration with High or Low defines
output trigger either at display value ≥ or ≤ limit value. The outputs can be programmed with a
time delay or with a hysteresis.
Time delay of the limit value outputs
The time delay is programmable from 0 to 99 s. This acts both when the limit value outputs are
switched on and off.
