VEGA VEGAFLEX 66 (-20…+250°C) 4 … 20 mA_HART two-wire - Manual (Page 9)

T
wo-wire electronics 4 … 20 mA/HART for power supply and
measured value transmission over the same cable.
T he supply voltage range can differ depending on the instrument
version.
T he data for power supply are specified in chapter "Technical data".
T he optional background lighting of the indicating and adjustment
module is powered by the sensor. A certain level of operating voltage
is required for this. You can find the exact voltage specifications in
chapter "Technical data".
T
he optional heating requires its own operating voltage. You can find
details in the supplementary instructions manual "Heating for indicat-
ing and adjustment module".
T
his function is generally not available for approved instruments.
3 .3 Operation
VEGAFLEX 66 can be adjusted with different adjustment media:
l
with indicating and adjustment module
l
with the suitable VEGA DTM in conjunction with an adjustment
software according to the FDT/DTM standard, e.g. PACTware and
PC
l
with manufacturer-specific adjustment programs AMS™ or PDM
l W ith a HART handheld
3 .4 Packaging, transport and storage
Y our instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
according to DIN EN 24180.
T he packaging of standard instruments consists of environment-

is also used. Dispose of the packaging material via specialised
recycling companies.
T ransport must be carried out under consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
