VEGABAR 86 • 4 … 20 mA/HART
45039-EN-131010
If a linearization curve is selected, the measuring signal is no longer
necessarily linear to the filling height. This must be considered by the
user especially when adjusting the switching point on the limit signal
transmitter.
In the menu items "Current output" you determine the properties of
the current output.
On instrumdents with integrated 2. current output, the properties for
each current output are adjusted individually. The following descrip-
tions apply to both current outputs.
In the menu item "Current output mode" you determine the output
characteristics and reaction of the current output in case of failure.
The default setting is output characteristics 4 … 20 mA, failure mode
< 3.6 mA.
In the menu item "Current output Min./Max.", you determine the reac-
tion of the current output during operation.
The default setting is min. current 3.8 mA and max. current 20.5 mA.
In the menu item "Lock/unlock adjustment", you can protect the
sensor parameters against unauthorized modification. The PIN is
activated/deactivated permanently.
The following adjustment functions are possible without entering the
PIN:
•
Select menu items and show data
•
Read data from the sensor into the display and adjustment mod-
ule.
Caution:
With active PIN, adjustment via PACTware/DTM as well as other
systems is also blocked.
You can change the PIN number under "Additional adjustments -
PIN".
This menu item enables the setting of the requested national lan-
guage.
