VEGA VEGADIS 62 - Manual (Page 24)

A flashing heart symbol is displayed as long as a HART communi-
cation takes place for the first time and the instrument is hence set to
the HART mode. The heart symbol is displayed permanently if the
HART communication is finished and the digital indication is
configured according to the measuring range and the unit of the
connected sensor.
When there is a HART communication through the control room during
operation, then the heat symbol flashes during the communication.
The VEGADIS 62 goes to HART multidrop mode if in the menu
"M
easurement", menu item "Address" an address unequal 0 is
adjusted. In this mode for HART sensors, the current signal is fixed to
4 mA and the measurement information is transmitted only via the
HART communication to the control room.
The VEGADIS 62 enquires the Primary Value (PV) of the transmitter
with the suitable address once. Afterwards the display behaves
passively, i.e. the transmission of additional measured values must be
requested from the control system. The bargraph is not displayed in
HART multidrop.
6 .3 Parameter description
Through the parameter adjustment the instrument is adapted to the
application conditions. The parameter adjustment is carried out via an
adjustment menu.
The adjustment menu is divided into three sections with the following
functions:
Measurement: Contains for example unit, measuring range, live
adjustment, damping, HART address
Indication: Contains for example unit, unit locking, display format,
filter, alarms min./max. storage
Configuration: Contains for example language, contrast, reset, user
unit, min./max. failure message, firmware version
Selection of the unit for the measuring range adjustment of the
connected transmitter
1) When opening this menu item, first of all the
basic unit of the connected sensor is displayed.
