VEGAMET 142 • 4 … 20 mA

63729-EN-210329

3.2 Principle of operation

Controller VEGAMET 142 feeds the connected 4 … 20 mA sensors,

processes the measured values and displays them. The compact

design is ideal for mounting on carrier rails in switching cabinets. A

graphic display as well as a turn/push button for quick on-site control

of the measuring point are also integrated.

Itenablessimplepumpcontrol,owmeasurementonopenchannels

andweirs,totalization,dierence,sumandaveragevaluecalcula-

tions. With the VEGAMET 142, limit values can be reliably monitored

andrelayscanbeswitched,e.g.foranoverllprotectionaccordingto

WHG.

Due to its various possibilities it is suitable for many industrial

branches as well as plant manufacturers.

The VEGAMET 142 controller can power the connected sensors

and process their measurement signals. The requested parameter is

shown on the display and also output to the integrated current output

for further processing. The measurement signal can thus be trans-

ferred to a remote display or a superordinate control system. Operat-

ing relays for control of pumps or other devices are also integrated.

3.3 Adjustment

On-site operation of the device is carried out via the integrated display

and adjustment unit. It consists of a graphic display and a central turn/

push button for menu adjustment.

The optionally integrated Bluetooth module enables in addition a wire-

less adjustment of VEGAMET 142 via standard adjustment tool:

•

Smartphone/tablet (iOS or Android operating system)

•

PC/notebook with Bluetooth LE or Bluetooth USB adapter (Win-

dows operating system)

Information:

Certain setting options are not possible or only possible to a limited

extent with the integrated display and adjustment unit, for example the

settingsforowmeasurementorpumpcontrol.Fortheseapplica-

tions, the use of PACTware/DTM or the VEGA Tools app is recom-

mended. An overview of the available applications and functions as

well as their adjustment options can be found in the appendix.

4.1 General instructions

VEGAMET 142 is designed for carrier rail mounting (top hat rail

35 x 7.5 according to DIN EN 50022/60715). Due to its protection

rating of IP20, the instrument is suitable for mounting in switching

cabinets. It must be mounted vertically.

A VEGAMET 142 in Ex version is an auxiliary, intrinsically safe instru-

ment and may not be installed in explosion-endangered areas.

The instrument is suitable for standard and extended ambient condi-

tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1.

Makesurethattheenvironmentalandambientconditionsspeciedin

chapter " Technical data" are maintained.

5 Connecting to power supply

5.1 Preparing the connection

Always keep in mind the following safety instructions:

•

The electrical connection must only be carried out by trained,

qualiedpersonnelauthorisedbytheplantoperator.

•

If overvoltage surges are expected, overvoltage arresters should

be installed.

Warning:

Only connect or disconnect in de-energized state.

Thedataforpowersupplyarespeciedinchapter"Technical data".

The voltage supply is connected with standard cable according to the

national installation standards.

Standard two-wire cable can be used to connect the sensors.

Note:

If the temperatures are too high, the cable insulation can be dam-

aged. Hence keep apart from the ambient temperature also the self-

heating of the instrument for the temperature resistance of the cable

in the connection compartment in mind.

1)

When used in the USA/Canada, only cables with copper conductors

may be used.

5.2 Sensor input mode active/passive

Through the selection of the terminals, you can choose between ac-

tive and passive operation of the sensor input.

•

In active mode, the controller provides the power for the con-

nected sensors. Power and measurement data are transmitted

over the same two-wire cable. This mode is provided for connec-

tion of measuring transducers without separate power supply

(sensors in two-wire version).

•

In passive mode the sensors are not powered, only the measured

value is transmitted. This input is for connection of transmitters

with their own separate voltage supply (sensors in four-wire ver-

sion). The VEGAMET 142 can also be looped into the existing

circuit like a normal ammeter.

Note:

With a VEGAMET 142 in Ex version, the passive input is not available.

5.3 Connecting

The power supply and the inputs and outputs are connected via

VEGAMET 142 • 4 … 20 mA

63729-EN-210329

6 Access protection

6.1 Bluetooth radio interface

Devices with a Bluetooth radio interface are protected against un-

wanted access from outside. This means that only authorized persons

can receive measured and status values and change device settings

via this interface.

Information:

If no Bluetooth connection to the device should be possible, Bluetooth

communication can be deactivated. Access via app or DTM is thus no

longer possible. The Bluetooth function can be deactivated/activated

in the menu item " Extended functions" under " Access protection -

Bluetooth communication".

A Bluetooth access code is required to establish Bluetooth com-

munication via the adjustment tool (smartphone/tablet/notebook).

This code must be entered once when Bluetooth communication is

establishedforthersttimeintheadjustmenttool.Itisthenstoredin

the adjustment tool and does not have to be entered again.

The Bluetooth access code is individual for each device. It is printed

on the device housing and is also supplied with the device in the

information sheet " PINs and Codes". The Bluetooth access code can

also be read out via the display and adjustment unit.

TheBluetoothaccesscodecanbechangedbytheuseraftertherst

connection is established. If the Bluetooth access code is entered

incorrectly, the new entry is only possible after a waiting period has

elapsed. The waiting time increases with each further incorrect entry.

The emergency Bluetooth access code enables Bluetooth communi-

cation to be established in the event that the Bluetooth access code

is no longer known. It can't be changed. The emergency Bluetooth

access code can be found in information sheet " Access protection".

If this document is lost, the emergency Bluetooth access code can

be retrieved from your personal contact person after legitimation.

The storage and transmission of Bluetooth access codes is always

encrypted (SHA 256 algorithm).

6.2 Protection of the parameterization

The settings (parameters) of the device can be protected against un-

wanted changes. The parameter protection is deactivated on delivery,

all settings can be made.

To protect the parameterization, the device can be locked by the user

with the aid of a freely selectable device code. The settings (param-

eters) can then only be read out, but not changed. The device code

is also stored in the adjustment tool. However, unlike the Bluetooth

access code, it must be re-entered for each unlock. When using the

adjustment app or DTM, the stored device code is then suggested to

the user for unlocking.

VEGAMET 142 • 4 … 20 mA

63729-EN-210329

The emergency device code allows unlocking the device in case the

device code is no longer known. It can't be changed. The emergency

device code can also be found on the supplied information sheet " Ac-

cess protection". If this document is lost, the emergency device code

can be retrieved from your personal contact person after legitimation.

The storage and transmission of the device codes is always encrypt-

ed (SHA 256 algorithm).

6.3 Storing the codes in myVEGA

If the user has a " myVEGA" account, then the Bluetooth access code

as well as the device code are additionally stored in his account under

" PINs and Codes".Thisgreatlysimpliestheuseofadditionaladjust-

7.4 Setup steps

Through parameter adjustment, the instrument is adapted to the indi-

vidual application conditions. A measurement loop calibration is the

most important step and should always be carried out. A scaling of

the measured value to the desired physical variable and unit, possibly

including a linearisation curve, is often useful. The adaptation of the

relay switching points or the setting of an integration time to smooth

the measured value are further standard adjustment options.

Information:

When using PACTware and the respective DTM or the VEGA Tools

app, additional settings can be carried out which are not possible or

only partly possible with the integrated display and adjustment unit.

Communication takes place via the built-in Bluetooth interface.
