6.4 Setup procedur

Before starting the actual parameter adjustment of a Proﬁbus PA

sensor, the address setting must ﬁrst be carried out. You will ﬁnd a

detailed description in the operating instructions manual of the

indicating and adjustment module or in the online help of PACTware or

DTM.

VEGABAR 61 can be used for level as well as for process pressure

measurement. Default setting is level measurement. The mode can be

changed in the adjustment menu.

Depending on the application only the respective subchapter "Level or

process pressure measurement" is of importance. There, you ﬁnd the

individual adjustment steps.

Level measurement

Set up VEGABAR 61 in the following sequence:

1 Selecting adjustment unit/density unit

2 Carry out position correction

3 Carrying out min. adjustment

4 Carrying out max. adjustment

In the menu item "Adjustment unit" you select the physical unit in which

the adjustment should be carried out, e.g. mbar, bar, ps i…

The position correction compensates the inﬂuence of the mounting

position or static pressure on the measurement. It does not inﬂuence

the adjustment values.

Informa

tion:

steps 1, 3 and 4 are not necessary for instruments which are

already preset according to customer speciﬁcations!

You can ﬁnd the data on the type label on the instrument or in the

menu items of the min./max. adjustment.

The indicating and adjustment module enables the adjustmetn without

ﬁlling or pressure. Thanks to this, you can carry out your settings

already in the factory without the instrument having to be installed.

The actual measured value is also displayed in the menu items for

min./max. adjustment.

In this menu item you select the adjustment unit as well as the unit for

the temperature indication in the display.

To select the adjustment unit (in the example switching over from bar

to mbar) you have to proceed as follows:

Selection options: mbar, bar, psi, Pa, kPa, MPa, inHg, mmHg, inH

mmH
