3.2 Principle of operation
The VEGADIS 62 is an external indicating and adjustment unit without
external energy for 4 … 20 mA/HART sensors. The instrument is used
for remote measured value indication and adjustment. It is looped in
any position directly into the signal cable.
The housing of VEGADIS 62 contains a filter element for ventilation.
Hence the insturment is also used for atmospheric pressure
compensation of a connected suspension pressure transmitter
VEGAWELL 52.
Fig. 2: Connection of the VEGADIS 62 to a suspension pressure transmitter
The VEGADIS 62 can be also used as external indication for a four-
wire sensor or a VEGAMET signal conditioning instrument with active
4 … 20 mA output.
Operation
The VEGADIS 62 is suitable for operation of all continuously
measuring VEGA sensors with HART output > 5.0:

Modes
3 Product description
l Radar and ultrasonic sensors
l Sensors with guided microwave
l Capacitive probes
l Pressure transmitter
l Previous instrument versions (replacement for VEGADIS 12)
The operation of respective sensors from other manufacturers is also
possible.
The VEGADIS 62 acts like a HART handheld with limited functions.
The following adjustment functions are available:
l Min./Max. adjustment
l zero/span adjustment (live adjustment)
l Damping
Basic mode: when used in a 4 … 20 mA signal cable, the VEGADIS
62 works as a pure indicating instrument. It measures the current in the
current loop and shows it as digital value as well as via a bargraph. All
settings of VEGADIS 62 are carried out manually via the buttons in the
front.
Adjustment volume: Indication scaling
HART standard: when used with a 4 … 20 mA/HART sensor, the
VEGADIS 62 operates as automatic indicating and HART adjustment
instrument. The VEGADIS 62 powered via the current loop listens
continuously to the HART communication of the control system with
the sensor. Changes of unit and/or measuring range are adapted
automatically.
The parameter adjustment of the sensor is carried out via HART
communication. During the parameter adjustment, the VEGADIS 62
operates as a Secondary Master to the sensor.
Adjustment volume: Sensor functions, indication scaling
HART multidrop: The VEGADIS 62 can also be used as indicator for
a bus participant on a HART multidrop system. For this purpose, it is
looped into the bus and the address of the participant is set in the
VEGADIS 62. The instrument reads out the measured values with unit
via the HART signal and displays them.
Adjustment volume: Sensor function damping, indication scaling
3.3 Packaging, transport and storage
Packaging

Your 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.
The packaging of standard instruments consists of environmentfriendly, recyclable cardboard. For special versions, PE foam or PE foil
is also us ed. Dispose of the packaging material via specialised
recycling companies.

Moisture
Wall mounting
Carrier rail mounting
Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry. Rain and condensation water can thus drain off. This
applies mainly to outdoor mounting as well as installation in areas
where high humidity is expected (e.g. through cleaning processes) or
on cooled or heated vessels.

5.1 Preparing the connection
Safety instructions
Voltage supply
Connection cable
Always keep in mind the following safety instructions:
l Connect only in the complete absence of line voltage
l If voltage surges are expected, install overvoltage arresters
Power supply and current signal are carried on the same two-wire
cable. The voltage supply range can differ depending on the sensor.
The data for power supply are specified in chapter "Technical data".
Provide a reliable separation between the supply circuit and the mains
circuits according to DIN VDE 0106 part 101.
Keep in mind the following additional factors that influence the
operating voltage:
l Output voltage of the power supply unit can be lower under
nominal load (with a sensor current of 20.5 mA resp. 22 mA in
case of fault message)
l Influence of additional instruments in the circuit (see load values in
chapter "Technical data")
Operation of VEGADIS 62 in a HART multidrop system with the signal
conditioning instruments VEGAMET 625 or VEGASCAN 693 is not
supported.
The instrument is connected with standard two-wire cable without
screen. If electromagnetic interference is expected which is above the
test values of EN 61326-1 for industrial areas, screened cable should
be used.
For instruments with housing and cable gland, use cable with round
cross-section. A cable outer diameter of 5 … 9 mm (0.2 … 0.35 in)
ensures the seal effect of the cable gland. If you are using cable with a
different diameter, exchange the seal or use a suitable cable gland.
We generally recommend the use of screened cable for HART
multidrop mode.
Cable gland ½ NPT
Cable screening and
grounding
With plastic housing, the NPT cable gland or t he Conduit steel tube
must be screwed without grease into the threaded insert.
Max. torque for all housings see chapter "Technical data"
If screened cable is necessary, connect the cable screen on both ends
to ground potential. In the sensor, the screen must be connected
directly to the internal ground terminal. The ground terminal on the
outside of the housing must be connected to the potential equalisation
(low impedance).
36469-EN-120329
VEGADIS 62 13
5 Connecting to power supply
If potential equalisation currents are expected, the connection on the
processing side must be made via a ceramic capacitor (e. g. 1 nF,
1500 V). The low frequency potential equalisation currents are thus
suppressed, but the protective effect against high frequency interference si gnals remains.
Warning:
Significant potential differences exist inside galvanization plants as
well as on vessels with cathodic corrosion protection. Considerable
equalisation currents can flow over the cable screen if the screen is
grounded on both ends.
To avoid this in such applications, the cable screen must be connected
to ground potential only at one end (in the switching cabinet). The
cable screen must not be connected to the internal ground terminal in
the sensor and the outer ground terminal on the housing must not be
connected to the potential equalisation!
Information:
The metal parts of the instrument (antenna, transmitter, concentric
tube, etc.) are conductive connected with the inner and outer ground
terminal on the housing. This connection exists either directly metallic
or with instruments with external electronics via the screen of the
special connection cable.
You can find specifications to the potential connections within the
instrument in chapter "Technical data".
5.2 Connection technology and steps
Connection technology
Connection procedure
14 VEGADIS 62
The connection of the signal cable is carried out via spring-loaded
terminals in the housing.
The indicating and adjustment module is connected via a cable with
coupling to the housing.
Proceed as follows:
1 Unscrew the housing cover
36469-EN-120329
5 Connecting to power supply
2 Remove the indicating and adjustment module by turning it slightly
to the left
Fig. 6: Dismounting of the indicating and adjustment module
3 Loosen compression nut of the cable glands
4 Remove approx. 10 cm (4 in) of the signal cable mantle, strip
approx. 1 cm (0.4 in) insulation from the ends of the individual
wires
36469-EN-120329
VEGADIS 62 15
5 Connecting to power supply
5 Insert the cable into the sensor through the cable entry
Fig. 7: Connection steps 5 and 6
6 Insert the wire ends into the terminals according to the wiring plan
Note:
Solid cores as well as flexible cores with cable end sleeves are
inserted directly into the terminal openings. In case of flexible cores
without end sleeves, press the terminal with a small screwdriver; the
terminal opening is freed. When the screwdriver is released, the
terminal closes again.
7 Check the hold of the wires in the terminals by lightly pulling on
them
8 Connect the screen to the internal ground terminal, connect the
outer ground terminal to potential equalisation
9 Attach the indicating and adjustment module again and turn it
slightly to the right
10 Tighten the compression nut of the cable glands. The seal ring
must completely encircle the cable
11 Screw the housing cover back on
The electrical connection is finished.
Note:
The terminal block is pluggable and can be removed from the
electronics. To do this, lift the terminal block with a small screwdriver
and pull it out. When inserting the terminal block again, you should
hear it snap in.
