VEGA VEGAPULS 63 (≥ 2.0.0 - ≤ 3.8) 4 … 20 mA_HART - two-wire - Manual (Page 10)

T
he antenna of the radar sensor emits short radar pulses with a
duration of approx. 1 ns. These pulses are reflected by the product
and received by the antenna as echoes. The transit time of the radar
pulses from emission to reception is proportional to the distance and
hence to the level. The determined level is converted into an
appropriate output signal and outputted as measured value.
4 … 20 mA/HART two-wire electronics for voltage supply and
measured value transmission on 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
T he instrument can be adjusted with the following adjustment media:
l W ith 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-
friendly, recyclable cardboard. For special versions, PE foam or PE foil
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
damage to the device.
