6.7.5 Current output
Use the Current output
Current output
Current output
Current output menu to specify the type of data that the current output must supply. The
supervisor can set the output function (level or distance), the output range and the error delay.
The "scaling min." and the "scaling max." values are set in the Basic parameters
Basic parameters

Output function
Select an output function to scale the current values
in relation to a given point (the top process
connection (distance measurement) or the bottom
process connection (level measurement) in the
bypass chamber.

Output range
This menu item sets the limits of the electrical
current range to 1 of the 2 available options: standard
limits (4...20 mA) or NAMUR NE 43-compliant limits
(3.8...20.5 mA). It also tells the device what to do if an
error occurs. For example, if you set Output range

The time after which the current output changes to an
error value. The error value shows that there is a
measurement error. min= minutes and s= seconds.
