Scaling start, scaling end
A value range is assigned to the physical output signal by specifying the zero point and end value (scal-
ing). The default setting corresponds to a value range of 0 to 100%.
If, for example, a temperature with a value range from 150 °C to 500 °C is to be issued via an analog
output with signal type 0 to 20 mA, the start value must be set to 150 (corresponding to 0 mA) and the
end value to 500 (corresponding to 20 mA).
Response in case of a fault
Output value in the event of fault:
Signal type (parameter "Output signal")
Voltage 0 to 10 V
Current 0 to 20 mA
Current 4 to 20 mA
Voltage 10 to 0 V
Current 20 to 0 mA
Current 20 to 4 mA
This behavior also applies for probe/wire break or probe/conductor short-circuit. Error detection depends
on the type of measuring probe (see technical data, measuring circuit monitoring).

Limits according to NAMUR recommendation NE 43 for signal type 4 to 20 mA:
Measurement information M
Failure information A
for deviation below measured value/short-circuit ("NAMUR Low")
Failure information A
for deviation above measured value/probe break ("NAMUR High")

Selection/settings
Value of the output signal after deviation above or below the measuring range (out
of range = o-o-r)
The selection options "Defined low value" and "Defined high value" are only avail-
able for the output signals 4 to 20 mA and 20 to 4 mA.
Replacement value
Defined low value
Defined high value
0 to 22 mA or
0 to 10 V
