VEGA VEGADIS 62 - Manual (Page 23)

By pushng the [OK] key, the parameter adjustment mode will be
started. The parameter adjustment is carried out via an adjustment
menu. The same menu window is opened from which the parameter
adjustment mode is quit during the last parameter adjustment. Single
points in the menu can be selected with the [↑] and [↓] keys. The
branching to the next submenu is carried out by pushing the [OK] key
again.
In a submenu you change with [OK] to the editing function, this means
the displayed settings can be changed. If the indication is in the editing
mode, then the edited value flashes. Editing is carried out with the [↑]
and [↓] keys.
In the editing mode, you jump to the range end when you hold the [↑]
or [↓] key by pushing [ESC]. by pushing [OK] you jump to the range
start. When holding the [↑] keyand by pushing the [↓] key (and vice
versa), then the value zero is adjusted, When increasing a value at the
end of the adjustment range, you jump to the range start and vice
versa.
The editing function and be quit with [ESC] (without accepting the
modifications) and with [OK] (accepting the modifications).
6 .2 Modes
In the following cases, the VEGADIS 62 goes automatically to basic
mode:
l If it does not find a HART sensor within approx. 70 s after
switching on
l If a key was pressed in the switching on phase
In basic mode, it works exclusively as an indicating instrument on the
4 … 20 mA cable, the HART symbol is not displayed.
The VEGADIS 62 goes automatically to the mode HART standard
when a functioning HART communication to the sensor was
established.
The displayed measured value is calculated from the loop current and
the adjustment data of the sensor.
During operation, the VEGADIS 62 monitors the current loop
constantly for a HART communication between control system and
sensor. If the unit changes or adjustments of the connected sensor are
carried out by the control system, the unit and the corresponding
indicating range are automatically adapted in VEGADIS 62. The
prerequisite, however, is that the unit set in the sensor must be stored
in VEGADIS 62.
The VEGADIS 62 also allows the measuring range and calibration of
the connected HART sensor to be modified. For this, no additional
instruments or tools are necessary. Further changes to the config-
uration of the sensor cannot be carried out.
