7 Setup with the integrated display and adjustment unit
VEGAMET 391 • With SIL qualification
38704-EN-130228
Note:
Approx. 10 minutes after the last pressing of a key, an automatic reset
to measured value indication is triggered. Any values not confirmed
with [OK] will not be saved.
7.2 Setup steps
Through parameter adjustment, the instrument is adapted to the indi-
vidual application conditions. A measurement loop calibration is the
most important step and should always be carried out. A scaling of
the measured value to the desired physical variable and unit, possibly
including a linearization curve, is often useful. The adaptation of the
relay switching points or the setting of an integration time (damping)
to smooth the measured value are further standard adjustment op-
tions.
A setup assistant is available for easy, convenient setup. It guides the
user through the standard applications and settings step by step.
As a standard feature, the parameterization of the instrument is
locked to protect it against unauthorized operation. The instrument is
unlocked by entering a PIN.
Information:
When using PACTware and the respective DTM, additional settings
can be carried out which are not possible or only partly possible with
the integrated display and adjustment unit. Communication is carried
out via the integrated USB interface. You find further information in
chapter "Set up with PACTware".
After being switched on, VEGAMET 391 mit SIL-Qualifikation first of
all carries out a short self-check. The following steps are carried out:
•
Internal check of the electronics
•
indication of the instrument type, firmware version as well as the
instrument TAG (instrument name)
•
The output signals jump briefly to the set fault value
Then the current measured values will be displayed and outputted.
The measured value indication shows the digital indication value, the
measurement loop name (measurement loop TAG) and the unit. An
analogue bar graph can also be displayed. If flow measurement with
totalizer is activated, an additional indication window with totalizer
becomes available. By pushing the [>] key you can move between the
different indication options.
→
[OK], you move from the measured value indication into the main
menu. Here, you have the choice between the setup assistant for
the most important settings and the complete classic menu.
At the beginning of every setup or parameter adjustment, you have
the choice of continuing with the setup assistant or the classic menu
