3.2Principle of operation
VEGASCAN 693 is a universal signal conditioning instrument
for a number of applications such as level,gauge and process
pressure measurement.At the same time,it can serve as
power supply unit for connected sensors.VEGASCAN 693 is
designed for connection of 15 independent VEGA HART
sensors (5with Ex applications). Hence 15 (5with Ex)
independent measurements can be carried out.
The measured values can be retrieved through one of the
integrated interfaces (RS232/Ethernet)via modem or network
and displayed with the web browser or Visual VEGA.
Furthermore it is possible to transmit measured values or
messages by e-mail.The use of VEGASCAN 693 is
particularly suitable of stocktaking,VMI (Vendor Managed
Inventory)and remote enquiry.
VEGASCAN 693 signal conditioning instrument can power the
connected sensors and also evaluate their measuring signals.
The requested parameter is indicated in the display and,in
addition,outputted to the integrated interface and the web
server for further processing.On request,the measured values
can be sent event or time-controlled via e-mail to different
addressees.
Wide-range power supply unit with 20 …253 VAC/DC for
world-wide use.
You can find detailed information on the power supply in the
"Technical data"in the "Supplement".
3.3Adjustment
VEGASCAN 693 can be adjusted with the following adjust-
ment media:

4Mounting
4.1General instructions
Each series 600 instrument consists of the actual signal
conditioning instrument as well as a plug-in socket for carrier
rail mounting.Because it has protection class IP 30 or IP 20,
the instrument is intended to be used in switching cabinets.
4.2Mounting information
The plug-in socket is constructed for carrier rail mounting acc.
to EN 50022.Power supply is connected to terminals 17 and
18.For neighbouring series 600 signal conditioning instru-
ments,it is possible to continue connection L1and Ndirectly
via the supplied bridges.
Danger:
The bridges must never be used with single instruments or at
the end of a row of instruments.If this rule is not heeded,there
is a danger of coming into contact with the operating voltage or
causing a short circuit.
A VEGASCAN 693 in Ex version is an auxiliary,intrinsically
safe instrument and must not be installed in hazardous areas.
Before setup,the Ex separating chamber must be attached (as
shown below)with Ex versions.Safe operation can be only
ensured if the operating instructions manual and the EU type
approval certificate are observed.VEGASCAN 693 must not
be opened.
All signal conditioning instruments are provided with different
gaps depending on type and version (mechanical coding).
The plug-in socket is provided with coded pins that can be
inserted to prevent accidental interchanging of the various
instrument types.
With a VEGASCAN 693 in Ex version,the supplied coded pins
(type coded pin and Ex coded pin)must be inserted by the
user acc.to the below chart.

5Electrical connection
5.1Preparing the connection
Always observe the following safety instructions:
lConnect only in the complete absence of line voltage
lIf overvoltage surges are expected,overvoltage arresters
should be installed
Tip:
We recommend VEGA overvoltage arresters B61-300 (power
supply VEGASCAN 693)and B62-36G(sensor supply).
In hazardous areas you should take note of the appropriate
regulations,conformity and type approval certificates of the
sensors and power supply units.
The power supply can be 20 …253 VAC,50/60 Hz.
Power supply of VEGASCAN 693 is connected with standard
cable acc.to the national installation standards.
Standard two-wire cable with screening can be used for
connecting the sensors.The screening is absolutely neces-
sary to ensure interference-free operation with HART sensors.
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 outside on the
sensor housing must be connected to the potential equal-
isation (low impedance).
If potential equalisation currents are expected,the screen
connection on the VEGASCAN 693 must be made via a
ceramic capacitor (e.g.1nF,1500 V). The low frequency
potential equalisation currents are thus suppressed,but the
protective effect against high frequency interference signals
remains.
Take note of the corresponding installation regulations for Ex
applications.In particular,make sure that no potential equal-
isation currents flow over the cable screen.In case of
grounding on both sides this can be achieved by the use of a
capacitor or a separate potential equalisation.

5.2Connection steps
Tip:
Before the actual setup,each HART sensors must be
assigned an address (see chapter "Setup"). When assigning
an address,only one sensor should be connected to
VEGASCAN 693.Depending on the installation location of the
sensors,it can be advantageous to carry out this addressing
before installing and connecting the sensors.This can be
conveniently carried out e.g.in the workshop.You just need a
24 Volt power supply as well as an indicating and adjustment
module PLICSCOM or the adjustment software PACTware™
with VEGACONNECT.
For electrical connection,proceed as follows:
1Snap socket without VEGASCAN 693 onto the carrier rail
2Connect sensor cable to terminal 1/2(active input)or 3/4
(passive input), provide a screening
3When using several sockets,loop the power supply by
means of bridges
4Connect power supply (switched off)to terminal 17 and 18
5If necessary,connect relays or other outputs
6Insert VEGASCAN 693 into the plug-in socket and screw it
down tightly
The electrical connection is finished.
Before setting up Ex versions,make sure the Ex separating
chamber is plugged onto the left side of the housing (above the
sensor terminals). The pins for type and Ex coding must also
be inserted correctly.
Information:
lOn the active input (terminals 1/2), VEGASCAN 693
provides the power supply for the connected sensors.
Power supply and measured value transmission are
carried out via the same two-wire cable.This operating
mode is intended for sensors without separate power
supply (sensors in two-wire version).
lOn the passive input (terminals 3/4), the sensors are not
powered,only the measured value is transmitted.This
input is for connection of transmitters with their own,
VEGASCAN 693 -15-channel HART signal conditioning instrument 13
Electrical connection
29252-EN-060513

separate power supply (sensors in four-wire version). The
connection and operation in Ex ia is not permitted on the
passive input.
Note:
VEGASCAN 693 is designed for connection of up to 15 HART
sensors (5with Ex). Because they are accessed via different
addresses in the HART multidrop mode,all sensors must be
connected to the same sensor input.These are either
terminals 1/2(active input)or terminals 3/4(passive input).
Mixed operation of active and passive input is not possible.
Since this is a digital bus system,only one two-wire cable
should lead to the sensors.Adistributor can then be
connected directly forward of the sensors.As an alternative,
the connection cable can be looped through the second cable
entry on the sensor housing.

6Setup with the integrated indicating and
adjustment unit
6.1Adjustment system
The integrated indicating and adjustment unit is used for
measured value display,adjustment and diagnosis of VEGA-
SCAN 693 as well as the connected sensors.The indication
and adjustment is carried out via the clear,graphic-capable
display with background lighting as well as four keys.The
adjustment menu with selectable language is clearly structured
and enables easy setup.
Certain adjustment options are not possible or are partially
restricted with the integrated indicating and adjustment unit,e.
g.the settings for the e-mail server.For such applications,the
use of PACTware™with appropriate DTMs is recommended.

Note:
Approx.10 minutes after the last pressing of a key,an
automatic reset to measured value indication is triggered.Any
values not confirmed with [OK]will not be saved.
6.2Setup procedure
Setup encompasses mainly the selection of the application,
assignment of HART addresses and adjustment of measure-
ment loops.Scaling the measured value to the requested size
and unit (possibly with the application of a linearization curve),
as well as setting an integration time for smoothing the
measured value,are additional setup steps.
For instruments with Ethernet interface,the instrument must be
provided with the host name and IP addr./Subnet mask.If
necessary,the e-mail/web server can also be configured with
PACTware™.
VEGASCAN 693 can process measured values of several
connected HART sensors.All measured values are trans-
mitted as digital HART signals on the same cable (bus). An
analogue 4…20 mAtransmission is not possible.An own,
unique address (address range 1-15)must be assigned first of
all to each connected sensor.This mode is also called HART
multidrop mode.Addressing can be done directly on each
HART sensor via the respective adjustment unit or an
appropriate adjustment software.As an alternative,the setting
of the sensor address can be also carried out via the
VEGAMET menu under "Service -Sensor address".
Note:
When addresses are being assigned,only one sensor with a
particular address must be connected on the bus.If this is not
the case,the sensor cannot be accessed and it is not possible
to assign an address.

After being switched on,VEGASCAN 693 first of all carries out
a short self-check.The following steps are carried out:
lInternal check of the electronics
lindication of the instrument type,firmware version as well
as the instrument TAG (instrument name)
lthe output signals jump briefly to the set fault current
Then the current measured values will be displayed and
outputted.
The measured value indication displays three measured
values each in one common window.The digital display value,
the measurement loop designation (meas.loop TAG)and the

Because VEGASCAN 693 can read the measured values of
up to 15 sensors (5with Ex), the individual sensors must be
assigned to the measurement loops.After the addresses of the
HART sensors are assigned,a list with the existing sensors
can be prepared and displayed.Now you can assign the
requested sensor to each measurement loop.
For transmission,VEGASCAN 693 must be informed which
sensor value should be used for further processing.Depend-
ing on the sensor type this can be distance,pressure,interface
or temperature.If a sensor can deliver two measured values,
e.g.pressure and temperature with VEGABAR sensors,a
separate measurement loop must be assigned for each input
variable.When HART sensors of other manufacturers are
connected,the options PV (Primary Value)and SV (Secondary
Value)will be available.The parameter to be transmitted is
stated in the operating instructions manual of the respective
sensor manufacturer.
