VEGAMET 391 • 4 … 20 mA/HART
36032-EN-130701
When the instrument displays a failure, further information of the
failure is available via the menu item "Diagnosis - Device status".
Furthermore the indication of the input current, the sensor status, the
switch on period and the relay status as well as the input status of the
digital inputs are possible.
The simulation of a measured value is used to check the outputs and
connected components. The simulation can be applied to the percent-
age value, the lin. percentage value and the sensor value.
Note:
Please note that connected system parts (valves, pumps, motors,
control systems) are influenced by the simulation, thus unintentional
plant operating conditions can occur. The simulation is terminated
automatically after approxminately 10 minutes.

Carry out your settings via the appropriate keys and save with
[OK].
Several reset options are available. A reset to basic settings resets
all settings (with a view exceptions) to default. Exceptions are: host
name, IP address, subnet mask, time, language. Further possibilities
are reset of the totalizer as well as the power-on time and relay failure.
The instrument can also be restarted if desired.
The signal conditioning instrument can be locked with a PIN to protect
the set parameters against unauthorized modification. After activa-
tion, it is not possible to carry out a parameter adjustment via the
built-in display and adjustment unit without entering the previously
specified PIN. This locking does not apply to parameter adjustment
with PACTware and the respective DTM.
With every 4 … 20 mA/HART sensor, the measured value can be
transmitted via analog current signal or digital HART signal. This is
regulated via the HART mode or the address. If a HART sensor is set
