1.1 Function, configuration and mounting

Function

Ex-separator VEGATRENN 547 V Ex is used
for intrinsically safe, galvanically isolated
supply of up to two ultrasonic or radar
sensors. At the input side it is connected to
the two-wire-VBUS-line of the signal
conditioning instrument and provides at the
output side 2 x 2 ib-circuits. Each sensor is
supplied via two ib-circuits so that two
sensors can be connected to Ex-separator.

The Ex-separator can be used in conjunction
with the following signal conditioning
instruments or sensors:

- VEGAMET 514␣ V and 515␣ V

- EV-card of VEGALOG 571

- ultrasonic sensors VEGASON series 80

- radar sensors VEGAPULS series 64 and

series 80 for intrinscially safe supply “ib“.

The intrinsically safe ib-circuits are isolated as
well as from the not intrinsically safe circuits.

Configuration

Configuration

The Ex-separator VEGATRENN 547 V Ex is
designed in 19“-technology with 5 TE (= 25,4
mm). The connection is made via a multiple
plug acc. to DIN 41 612.

Mounting

There are the following mounting possibilities

- in housing type 506 with VEGAMET

- in carrier BGT 596 Ex with VEGAMET

- carrier BGT LOG 571 *) with VEGALOG

2 Mounting

The Ex-separator VEGATRENN 547 V Ex can
be mounted as follows:

- in carrier BGT 596 Ex or
BGT LOG 571

- in housing type 506

Mounting in carrier

First of all mount the Ex-module into your
carrier. The Ex-module consists of a multipoint
connector acc. to DIN 41 612, individual
coded pins (see coding), a separating
chamber as well as guide rails and mounting
material.

Montage

Coding

The multipoint connector of the carrier or the
housing must be provided with coded keys to
avoid interchanging of the various signal
conditioning instruments. The multiple plug of
VEGATRENN is provided with the appropriate
holes (mechanical coding).

The instrument coding ensures that the
various signal conditioning instruments are not
interchanged. The appropriate coded pins are
attached to each module or housing. Provide
the multipoint connector with these coded
pins acc. to the following table and figure.

Wire the connections of the multipoint
connector acc. to the wiring plan on the
following pages.

The multipoint connector is available as
follows:

- Wire-Wrap standard connection

1,0␣ x␣ 1,0␣ mm

- Plug connection 2,8␣ x␣ 0,8 mm

- Termi-Point standard connection

1,6␣ x␣ 0,8␣ mm

- Soldering connection

- Screw terminal 2␣ x␣ 0,5␣ mm

Further information concerning mounting is
stated in the operating instructions of the
carrier.

Mounting in single housing

The housing socket can be either screwed
directly to a mounting plate or plugged on a
carrier rail (TS 35 x 7,5 acc. to EN 50 022 or
TS 32 acc. to EN 50 035). Further information
concerning mounting are stated in the
operating instructions of the housing. Connect
the wires acc. to the wiring plan.

The Ex-coding with fixed coded pins ensures
that not-Ex and Ex-instruments are not
interchanged.

3.1 Installation information

Generally the following instructions must be
noted for installation:

Installation place

VEGATRENN 547 V Ex as well as the
appropriate signal conditioning instrument
must be generally installed outside the
hazardous area.

Protection

In Ex-applications protection IP 20 must be
maintained. Cover the gaps or free modules
from the front with appropriate blind covers.

Ex-separating chamber

An Ex-separating chamber must be mounted
to the connections of VEGATRENN to ensure
sufficient “air and creep distances“. Loop the
cable through the Ex-separating chamber and
connect the cables. Fasten the Ex-separating
chamber with the lower screw. Note the
operating instructions of the carrier BGT 596
Ex.M.

Mounting in carrier

When you mount VEGATRENN in a carrier,
you have to use a VEGA-Ex-module. Keep a
distance of at least 10 mm ( 2TE) to module
cards of other manufacturers. If you want to
mount VEGATRENN in the complete left
position in the carrier, a blind cover of at least
20 mm (4 TE) must be mounted in front of the
module of the instrument.

not intrinsically safe circuits so that the min.
distance of 50 mm must be kept.
When using a separating chamber (supplied
with the module) this condition is met.

General conditions

In addition the valid “installation and operating
instructions“ as well as the special conditions
and instructions in the conformity certificates
must be noted.

Separation from not intrinscially safe
circuits

A separating wall must be provided between
the connection parts of intrinsically safe and

3.2 Connection instructions

Not intrinsically safe input

The not intrinsically safe input of the Ex­separator is connected via a standard two­wire line with a signal conditioning instrument.
If electromagnetic interferences have to be
expected, screened cable should be used.
The screen must only be earthed at one end
of the signal conditioning instrument.

Intrinsically safe output

The wiring of the intrinsically safe outputs of
the Ex-separator with the sensors must meet
with the valid installation regulations. E.g. the
DIN-regulations prescribe that the connection
lines between Ex-separator and sensors must
be marked on the entire length. For coverings
light blue must be used as colour.

If electromagnetic interferences must be
expected, screened cable must be used. The
screen must only be earthed at one sensor.
