Analogue output (Scaling the measuring range)
• By means of the parameter OU2 you define whether the set
measuring range is provided as a 4 ... 20 mA signal (OU2 = I) or as
a 20 ... 4mA signal (OU2 = Ineg).
• With the parameter "Analogue start point" (ASP) the measured
value at which the output signal is 4 mA (20 mA for Ineg) is defined.
• With the parameter "Analogue end point" (AEP) the measured
value at which the output signal is 20 mA (4 mA for Ineg) is defined.
• Minimum distance between ASP and AEP: 50°C / 90°F.
Factory preset
The output signal is between 4 and 20 mA in the set measuring range

Behaviour in cases of exceeding or not reaching the limits of
the measuring range
• Measured temperature above the set measuring range: The output
signal rises to max. 20.5 mA / falls to min. 3.8 mA.
With a further increase of the measured temperature the diagnostic
output of the sensor provides a warning, the fault number Fnr - 43
is set.
• Measured temperature below the set measuring range: The output
signal falls to min. 3.8 mA / rises to max. 20.5 mA.
With a further decrease of the measured temperature the diagnostic
output of the sensor provides a warning, the fault number Fnr - 42
is set.
