3.2 Principle of operation
VEGADIS 11 is a digital indicating instrument for measured
value indication in 4 … 20 mA circuits. The measured value is
displayed digitally or as bargraph via the LC display. The
digital indication can be scaled. VEGADIS 11 is suitable for
wall and carrier rail mounting.
VEGADIS 11 is looped directly into the 4 … 20 mA circuits and
requires no separate external energy. Connection is carried
out via screw terminals in the housing.

3.3 Operation
For scaling the indication, VEGADIS 11 is equipped with an
adjustment module. Adjustment is carried out via a rotary
switch and two keys.
3.4 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 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"

4 Mounting
4.1 General instructions
VEGADIS 11 can be mounted
in any position. However,
vertical mounting is recommended. By doing so, penetration of
moisture can be avoided.
Use the recommended cables (see chapter "Connecting to
power supply") and tighten the cable gland.
4.2 Mounting instructions
VEGADIS 11 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
Installation position

5 Connecting to power supply
5.1 Preparing the
connection
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.
VEGADIS 11 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.
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 the VEGADIS 11, 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).
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 11 through the cable entry

With 4 mA no segment of the bar graph appears, with 20 mA
all segments appear. This assignment is fix.
You can scale the digital value to any value between -9999 …
+9999 via the adjustment module.
To scale the indication, proceed as follows:
1 Initial value: Set rotary switch to "zero"
2 Set the requested value, e.g. 0 with the [+] and [-] keys
3 Final value: Set the rotary switch to "span"
4 Set the requested value, e.g. 1000 with the [+] and [-] keys
5 Decimal point: Set the rotary switch to "point"
6 With the [+] and [-] keys you can adjust the requested
value, e.g. 8888 (no decimal point)
7 Set rotary switch to "OPERATE"
8 Screw the housing cover on
The adjustment data are effective, the output current 4 … 20 mA
corresponds to the actual level.

7 Maintenance and fault rectification
7.1 Maintenance
When used as
directed in normal operation, VEGADIS 11 is
completely maintenance free.
7.2 Remove interferences
The operator of the system is responsible for taken suitable
measures to remove interferences.
VEGADIS 11 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
is checking the output signal. The procedure
is described below. Further comprehensive diagnostics
options offer a PC with the software PACTware™ and the
suitable DTM. In many cases, the reasons can be determined
in this way and faults can be rectified.
However, should these measures not be 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.
Connect a handheld multimeter in the suitable measuring
range according to the wiring plan.

In Ex applications, the regulations for the wiring of intrinsically
safe circuits must be observed.
Depending on the failure reason and measures taken, the
steps described in chapter "Set up" must be carried out again,
if necessary.
