3.2 Principle of operation

Application area

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 (5 with Ex applications). Hence 15

 

(5 with Ex) independent measurements can be carried out.

 

On instruments with one of the optional interfaces (RS232/Ethernet),

 

the measured values can be retrieved via modem or network and

 

displayed by means of a web browser, Visual VEGA or WEB-VV. It is

 

also possible to send measured values and messages via e-mail. The

 

use of VEGASCAN 693 is particularly suitable for stocktaking, VMI

 

(Vendor Managed Inventory) and remote enquiry.

Functional principle

VEGASCAN 693 signal conditioning instrument can power up to

 

15 HART sensors and also evaluates their measuring signal via the

 

same cable. The measured value transmission is carried out via a

 

digital bus system (HART multidrop). The requested parameter is

 

shown 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.

Voltage supply

Wide-range power supply unit with 20 … 253 V AC/DC for world-wide

 

use.

 

Detailed information about the power supply can be found in chapter

 

"Technical data".

3.3 Adjustment

The instrument can be adjusted with the following adjustment media:

With integrated display and adjustment unit

an adjustment software according to FDT/DTM standard, e.g.

 

PACTware and a Windows PC

 

 

 

 

The entered parameters are generally saved in VEGASCAN 693,

 

 

 

 

when used with PACTware and PC also optionally in the PC.

 

 

 

 

Information:

 

 

 

 

When using PACTware and the corresponding VEGA DTM, additional

 

 

 

 

settings can be carried out which are not possible or only partly pos-

 

 

 

 

 

 

 

 

sible with the integrated display and adjustment unit. When using an

 

 

 

 

adjustment software, you either need one of the integrated interfaces

 

 

 

 

(RS232/Ethernet) or the interface converter VEGACONNECT.

 

 

 

 

Further instructions for setting up the web server and e-mail functions

 

 

 

 

can be found in the online help of PACTware or the VEGASCAN 693

4.1General instructions

Installation possibilities Each series 600 instrument consists of the actual signal conditioning instrument as well as a plug-in socket for carrier rail mounting (tophat rail 35 x 7.5 according to DIN EN 50022/60715). Because it has protection class IP 30 or IP 20, the instrument is intended to be used in switching cabinets.

 

4.2 Mounting instructions

Mounting

The plug-in socket is designed for carrier rail mounting. The operat-

 

ing voltage is connected to terminals 17 and 18. For neighbouring

 

series 600 instruments it is possible to continue connection L1 and

 

N directly via the supplied bridges.Max.five instruments can be con-

 

nected through in this way.

 

Danger:

 

Looping through via bridges is only allowed for operating voltage

 

(sockets L1 and N). The bridges must never be used with single

 

instruments, at the end of a row of instruments or with other sockets.

 

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 may not be installed in explosion-endangered 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 EG type approval certificate

 

are observed. VEGASCAN 693 must not be opened.

Instrument coding

All signal conditioning instruments are provided with different gaps

 

dependent 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 according

 

to the below chart.

5.1Preparing the connection

Note safety instructions Always keep in mind the following safety instructions:

Connect only in the complete absence of line voltage

If overvoltage surges are expected, overvoltage arresters should be installed

Take note of safety instructions for Ex applications

Select power supply Select connection cable

Cable screening and grounding

Select connection cable for Ex applications

In hazardous areas you must take note of the respective regulations, conformity and type approval certificates of the sensors and power supply units.

The voltage supply can be 20 … 253V AC/DC, 50/60 Hz.

The operating voltage of VEGASCAN 693 is connected with standard cable according to the national installation standards.

Standard two-wire cable can be used for connecting the sensors. The screening is absolutely necessary 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 on the outside of the sensor housing must be connected to the potential equalisation (low impedance).

If potential equalisation currents are expected, the screen connection on the side of VEGASCAN 693 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.

Take note of the corresponding installation regulations for Ex applications. In particular, make sure that no potential equalisation 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 procedure

Note:

Before the actual setup, each HART sensors must be assigned an address (address range 1-15), (see chapter "Setup").Address 0

(mode 4 … 20 mA) must not be used. When assigning an address, only one sensor should be connected to VEGASCAN 693. If connection is completed already, the wiring must be briefly cancelled for addressing. 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.

Move on to electrical connection and proceed as follows:

1. Snap the socket without VEGASCAN 693 onto the carrier rail

12

VEGASCAN 693 • 15-channel HART signal conditioning instrument

130701-EN-29252

5 Electrical connection

2.Connect sensor cable to terminal 1/2 (active input) or 3/4 (passive input), provide a screening

3.When using several sockets, loop the power supply by means of bridges

4.Connect power supply (switched off) to terminal 17 and 18

5.If necessary, connect relays or other outputs

6.Insert VEGASCAN 693 into the plug-in socket and screw it down tightly

Note:

If the addressing of the sensors is not yet carried out, only one sensor must be connected.Then the addressing (see chapter "Setup") is carried out.Afterwards, the first sensor must be disconnected again and the next sensor must be connected as well as the addressing must be carried out. Carry out this procedure as long as all sensors have an own, unambiguous address. Then all sensors can be connected and setup can be carried out.

Before setting up Ex versions, make sure the Ex separating chamber is plugged on the left housing side (above the sensor terminals). The pins for type and Ex coding must also be inserted correctly.

Information:

 

 

 

On the active input (terminal 1/2), VEGASCAN 693 provides

 

 

 

 

 

 

power for the connected sensors. Power supply and measurement

 

 

 

 

 

 

 

data are transmitted over the same two-wire cable. This mode is

 

 

 

 

provided for connection of measuring transducers without sepa-

 

 

 

rate operating voltage (sensors in two-wire version).

 

 

 

On the passive input (terminals 3/4), the sensors are not supplied

 

 

 

with energy - only the measured value is transmitted. This input is

 

 

 

 

for instruments with their own separate operating voltage (sensors

 

 

 

 

in four-wire version or separators such as VEGATRENN 149). On

 

 

 

 

a VEGASCAN 693 in Ex version, the passive input is not available

 

 

 

 

due to approval/technical reasons.

Note:

VEGASCAN 693 is designed for connection of up to 15 HART sensors (5 with 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. A distributor 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. The address assignment of the sensors should be carried out before connection, see chapter "Set up".
