Optional instrument features are also described in this operating
instructions manual. The respective scope of delivery results from the
orderspecication.
3.2 Principle of operation
The VEGADIS 82 is suitable as measured value indication with
4 … 20 mA current loops. The instrument can be connected at any
point to the 4 … 20 mA signal cable. Separate, external energy is not
required.
TheVEGADIS82isalsosuitableforuseina4…20mA/HART
currentloop.TheHARTsignalisnotinuenced,howeverasensors
parameter adjustment is not possible.
The measured value indication is carried out in the VEGADIS 82
integrated in the display and adjustment module.
Note:
The operation of a display and adjustment module with integrated
Bluetooth function is not supported by VEGADIS 82.
The VEGADIS 82 is suitable for connection to any 4 … 20 mA sensor.
The instrument is particularly designed for:
•
VEGAPULS WL 61
•
VEGAWELL 52
ThehousingofVEGADIS82containsalterelementforventilation.
The instrument is thus also used for atmospheric pressure compen-
sation for a submersible pressure transmitter.
The VEGADIS 82 can also be used as an external indicating device
for any four-wire sensor or a VEGAMET controller with active
4 … 20 mA output.

3.3 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The 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.
Transport must be carried out in due consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
•
Not in the open
•
Dry and dust free
•
Not exposed to corrosive media
•
Protected against solar radiation
•
Avoiding mechanical shock and vibration
•
Storage and transport temperature see chapter " Supplement -
Technical data - Ambient conditions"
•

3.4 Accessories
The display and adjustment module PLICSCOM is used for measured
value indication, adjustment and diagnosis.
The interface adapter VEGACONNECT enables the connection of
communication-capable instruments to the USB interface of a PC.
The sun protection protects the device from direct sunlight and thus
prevents overheating of the electronics. It also improves the readabil-
ity of the display when exposed to sunlight. The sun protection can be
used for wall and pipe mounting.

4.1 General instructions
VEGADIS 82 functions in any installation position.
Protect your instrument against moisture ingress through the following
measures:
•
Use a suitable connection cable (see chapter " Connecting to
power supply")
•
Tighten the cable gland or plug connector
•
Lead the connection cable downward in front of the cable entry or
plug connector
This applies mainly to outdoor installations, in areas where high
humidityisexpected(e.g.throughcleaningprocesses)andoncooled
or heated vessels.
Note:
Make sure that during installation or maintenance no moisture or dirt
can get inside the instrument.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.

authorised by the plant operator
•
If overvoltage surges are expected, overvoltage arresters should
be installed

test values of EN 61326-1 for industrial areas, screened cable should
be used.

Metric threads
In the case of instrument housings with metric thread, the cable
glands are screwed in at the factory. They are sealed with plastic
plugs as transport protection.

46591-EN-210216
Note:
You have to remove these plugs before electrical connection.
NPT thread
In the case of instrument housings with self-sealing NPT threads, it is
not possible to have the cable entries screwed in at the factory. The
free openings for the cable glands are therefore covered with red dust
protection caps as transport protection.
Note:
Prior to setup you have to replace these protective caps with ap-
proved cable glands or close the openings with suitable blind plugs.
On plastic housings, the NPT cable gland or the Conduit steel tube
must be screwed into the threaded insert without grease.
Max. torque for all housings, see chapter " Technical data".
If shielded cable is necessary, we recommend connecting the cable
shield on both ends to ground potential. In the VEGADIS 82, the
shield should be connected directly to the internal ground terminal.
In Ex systems it must be ensured that the grounding complies with the
installation regulations.
In electroplating plants as well as plants for cathodic corrosion protec-
tionitmustbetakenintoaccountthatsignicantpotentialdierences
exist. This can lead to unacceptably high currents in the cable screen
if it is grounded at both ends.
5.2 Connection technology and steps
The voltage supply and signal output are connected via the spring-
loaded terminals in the housing.
Connection to the display and adjustment module or to the interface
adapter is carried out via contact pins in the housing.
Information:
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 reinserting the terminal block, you should hear it
snap in.
Proceed as follows:
1. Unscrew the housing lid
2. If a display and adjustment module is installed, remove it by turn-
ing it slightly to the left
3. Loosen compression nut of the cable gland and remove blind
plug
4. Removeapprox.10cm(4in)ofthecablemantle,stripapprox.

5.6 Switch-on phase
After connecting the instrument to power supply or after a voltage
recurrence, the instrument carries out a self-check for approx. 10 s:
•
Internal check of the electronics
•
Indication of the instrument type, hardware and software version,
measurement loop name on the display or PC
•
Indication of a status message on the display or PC
The duration of the warm-up phase depends on the connected sen-
sor.

information on the display in chapter " Measured value indication -
Selection national language".
