6.2.4.1 Scaling the measuring range
•
With the parameter analog starting point (ASP), you determine at which
measurement value the output signal is 4 mA.
•
With the parameter analog end point (AEP), you determine at which
measurement value the output signal is 20 mA.
•
Minimum distance between ASP and AEP = 25 % of the measuring
range final value
Factory setting Scaled measuring range
MEW = Measuring range final value
The output signal is between 4 and 20 mA in the set measuring range.
Further signals are:
•
Flow above the measuring range: Output signal > 20 mA
•
Flow below the measuring range: Output signal between 3.6 and 4 mA.
6.2.5 Error messages
Recording range exceeded
(Flow > 120 % of the measuring range final value)
Flashing : Short-circuit in switch output 1*
Flashing : Short-circuit in switch output 2*
Flashing : Short-circuit in both switch outputs *
Flashing : Malfunction in probe
* The affected output is switched off as long as the short-circuit lasts.
These messages are shown even when the display is deactivated.
