Area of application
Functional principle
Supply
VEGADIS 12 is an adjustment and indicating unit for the
following VEGA pressure transmitters:
l VEGAWELL 72 4 … 20 mA/HART
l VEGABAR 74 4 … 20 mA/HART
l VEGABAR 75 4 … 20 mA/HART
VEGADIS 12 has the following functions:
l atmospheric pressure compensation for the pressure
transmitter
l Adjustment of the pressure transmitter
l Indication of the measured value (optional)
VEGADIS 12 is looped in the supply and signal circuit of the
pressure transmitter and requires no separate external energy.
Connection is carried out via screw terminals in the housing.
3.3 Operation
As a standard feature, VEGADIS 12 is equipped with an
adjustment module for the pressure transmitter. The optional
indication is located in the housing cover and is equipped with
a bargraf and a digital indication. In this version, the additional
adjustment elements for scaling of the indication are integrated.

3.4 Packaging, transport and storage
Product description
Packaging
Transport
Transport inspection
Storage
Storage and transport tem-
perature
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 environ-
ment-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 under 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 concealed 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:
l Not in the open
l Dry and dust free
l Not exposed to corrosive media
l Protected against solar radiation
l Avoiding mechanical shock and vibration
l Storage and transport temperature see "Supplement -
Technical data - Ambient conditions"
l Relative humidity 20 … 85 %

4.1 General instructions
Installation position
Moisture
Mounting versions
VEGADIS 12 can be mounted in any position. However,
vertical mounting is recommended. This avoids pollution of the
breather facility and moisture penetration.
Note:
There must be the same atmospheric pressure on the breather
facility as well as on the measurement loop. Otherwise the
measured value can be adulterated.
Use the recommended cables (see chapter "Connecting to
power supply") and tighten the cable gland.
4.2 Mounting instructions
VEGADIS 12 can be mounted as follows:
l on carrier rail 35 x 7.5 according to EN 50022
l on mounting plate or on the wall

5.1 Preparing the connection
Note safety instructions
Take note of safety
instructions for Ex
applications
Selecting connection cable
Always keep in mind the following safety instructions:
l Connect only in the complete absence of line voltage
In hazardous areas you should take note of the appropriate
regulations, conformity and type approval certificates of the
sensors and power supply units.
VEGABOX 01 or VEGADIS 12 is connected with standard two-
wire cable without screen. An outer cable diameter of 5 … 9 mm
ensures the seal effect of the cable entry. If electromagnetic
interference is expected which is above the test values of
EN 61326 for industrial areas, we recommend the use of
screened cable.

Connecting to power supply
Select connection
cable for Ex applications
Cable screening and grounding
Cable screen and grounding
for Ex applications
Take note of the corresponding installation regulations for Ex
applications.
If screened cable is necessary, connect the cable screen on
both ends to ground potential. In VEGABOX 01 or in
VEGADIS 12, the screen must be connected directly to the
internal ground terminal. The ground terminal outside on the
housing must be connected to the potential equalisation.
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 signals remains.
In Ex applications, one-sided grounding on the sensor is
recommended, see EN 60079-14.
5.2 Connection procedure
Proceed as follows:
1 Unscrew the housing cover
2 Loosen compression nut of the cable entry
3 Remove approx. 10 cm of the cable mantle, strip approx.
1 cm insulation from the individual wires
4 Insert the cable into VEGADIS 12 through the cable entry
5 Loosen screw terminals with a screwdriver
6 Insert the wire ends into the open terminals according to
the wiring plan
7 Tighten screw terminals again
8 Check the hold of the wires in the terminals by lightly
pulling on them
9 Connect the screen to the ground terminal
10 Connect the ground terminal outside on the housing
according to specification (low impedance)
11 Tighten the compression nut of the cable entry. The seal
ring must completely encircle the cable
12 Screw the housing cover on
The electrical connection is finished.

The set values are transmitted to the EEPROM memory and
remain there even in case of voltage loss.
Proceed as follows for adjustment with VEGADIS 12:
1 Open housing cover
2 Connect hand multimeter to terminals 10 and 12
3 Meas. range begin: Set rotary switch to "zero"
4 Empty the vessel or reduce process pressure
5 Set a current of 4 mA with the [+] and [-] keys
6 Meas. range end: Set rotary switch to "span"
7 Fill the vessel or increase process pressure
8 Set a current of 20 mA with the [+] and [-] keys
9 Operation: Set rotary switch to "OPERATE"
10 Close the housing cover
The adjustment data are effective, the output current 4 … 20 mA
corresponds to the actual
level or pressure.
Information:
The corresponding current values must be calculated and set
respectively for adjustment with part fillings or emptyings.
Example: For a part emptying of 25 %, a current of 4 mA +
4 mA = 8 mA must be set, for a part filling of 75 %, a current of
4 mA + 12 mA = 16 mA. VEGADIS 12 then calculates the
values for full and empty.
Adjustment steps, integration
time
Proceed as follows for the adjustment of the integration time
with VEGADIS 12:
1 Open housing cover
2 Set rotary switch to "ti"
3 Make sure that the integration time is set to 0 sec by
pressing the [-] key 10 times.
4 For every 1 sec. requested integration time, push the [+]
key once.

7.1 Maintenance
When used as directed in normal operation, VEGADIS 12 is
completely maintenance free.
7.2 Remove interferences
Reaction in case of failures
Causes of malfunction
Fault rectification
24 hour service hotline
Check pressure compensation
The operator of the system is responsible for taken suitable
measures to remove interferences.
VEGADIS 12 offers maximum reliability. Nevertheless faults
can occur during operation. These may be caused by the
following, e.g.:
l Sensor
l Process
l Supply
l Signal processing
The first measure to take is to check the output signal as well
as the atmospheric pressure compensation. The procedure is
described below. Further comprehensive diagnostics can be
carried out on a PC with the software PACTware™ and the
suitable DTM. In many cases, the causes can be determined in
this way and faults can be rectified.
However, if these measures are not successful, call the VEGA
service hotline in urgent cases under the phone no. +49 1805
858550.
The hotline is available to you 7 days a week round-the-clock.
Since we offer this service world-wide, the support is only
available in the English language. The service is free of
charge, only the standard telephone costs will be charged.
First of all open the housing cover. The indicated measured
value must not change. However, if the indicated value
changes nevertheless, the compensation of the atmospheric
pressure is not ensured. Check the breather facility on the
housing and the capillaries in the special cable.
Checking the 4 … 20 mA signal

? 4 … 20 mA signal missing
l Wrong connection to power supply
à Check connection according to chapter "Connection
steps" and if necessary, correct according to chapter
"Wiring plan"
l No voltage supply
à Check cables for breaks; repair if necessary
l supply voltage too low or load resistance too high
à Check, adapt if necessary
? Current signal 3.6 mA; 22 mA
l electronics module or measuring cell defective
à Exchange instrument or return instrument for repair
In Ex applications, the regulations for the wiring of intrinsically
safe circuits must be observed.
Reaction after fault rectifica-
tion
Depending on the failure reason and measures taken, the
steps described in chapter "Set up" must be carried out again,
if necessary.
