1 For your safety

1.1 Authorised personnel

All operations described in this operating instructions manual must

be carried out only by trained specialist personnel authorised by theplant operator.

During work on and with the device the required personal protectiveequipment must always be worn.

1.2 Appropriate use

VEGABAR 82 is a slave sensor for electronic dierential pressuremeasurement.

You can nd detailed information about the area of application in

chapter "Product description".

Operational reliability is ensured only if the instrument is properlyused according to the specications in the operating instructionsmanual as well as possible supplementary instructions.

1.3 Warning about incorrect use

Inappropriate or incorrect use of the instrument can give rise toapplication-specic hazards, e.g. vessel overll or damage to system

components through incorrect mounting or adjustment.

1.4 General safety instructions

This is a high-tech instrument requiring the strict observance of stand-ard regulations and guidelines. The user must take note of the safetyinstructions in this operating instructions manual, the country-specicinstallation standards as well as all prevailing safety regulations and

accident prevention rules.

The instrument must only be operated in a technically awless andreliable condition. The operator is responsible for trouble-free opera-tion of the instrument.

During the entire duration of use, the user is obliged to determine the

compliance of the necessary occupational safety measures with the

current valid rules and regulations and also take note of new regula-tions.

1.5 CE conformity

The device fullls the legal requirements of the applicable EC guide-lines. By axing the CE marking, we conrm successful testing of theproduct.

You can nd the CE Certicate of Conformity in the download section

of our homepage.

1.6 Permissible process pressureThe permissible process pressure is specied on the type label with"Process pressure", see chapter "Conguration". For safety reasons,

this range may not be exceeded. This applies even if a measuring cellwith a measuring range (order-related) higher than the permissiblepressure range of the process tting is installed.

1.7 Environmental instructions

Protection of the environment is one of our most important duties.That is why we have introduced an environment management systemwith the goal of continuously improving company environmental pro-tection. The environment management system is certied accordingto DIN EN ISO 14001.

Please help us fulll this obligation by observing the environmentalinstructions in this manual:

• Chapter "Packaging, transport and storage"

• Chapter "Disposal "

3.1 General instructions for use of the instrument

Protect your instrument against moisture penetration through the fol-

lowing measures:• Use the recommended cable (see chapter "Connecting to power

supply ")

• Tighten the cable gland

• Turn the housing in such a way that the cable gland points down-ward

• Loop the connection cable downward in front of the cable gland

This applies particularly to:

• Outdoor mounting

• Installations in areas where high humidity is expected (e.g. through

cleaning processes)• Installations on cooled or heated vessels

3.2 Ventilation and pressure compensation

The lter element is mounted into the electronics housing. It has thefollowing functions:

• Ventilation of the electronics housing

• Atmospheric pressure compensation (with relative pressure meas-uring ranges)

→ Turn the housing so that the lter element points downward afterthe instrument is installed. This provides better protection againstbuildup.

With the following instruments a blind plug is installed instead of thelter element:

• Instruments in protection IP 66/IP 68 (1 bar) - ventilation via capil-laries in non-detachable cable

• Instruments with absolute pressure

3.3 Combination Master - Slave

In principle, any sensor combination within the VEGABAR 80 series isallowed. The following requirements must be fullled:

• Conguration, Master sensor suitable for electronic dierential

pressure• Pressure type is identical for both sensors, i.e. relative pressure/

relative pressure or absolute pressure/absolute pressure

• Master sensor measures the higher pressure

• Measurement setup as shown in the following chapters

The measuring range of each sensor is selected to t the measuringpoint. Hence the measuring ranges of master and slave do not haveto coincide exactly.

Depending on the application, individual combinations can result, seefollowing table with examples:

4.1 Connecting

The connection to the Master sensor is carried out via spring-loaded

terminals in the housing.Information:

The terminal block is pluggable and can be removed from theelectronics. To do this, lift the terminal block with a small screwdriverand pull it out. When reinserting the terminal block, you should hear itsnap in.

Proceed as follows:

1. Unscrew the housing cover

2. Loosen compression nut of the cable entry gland

3. Remove approx. 10 cm (4 in) of the cable mantle, strip approx.1 cm (0.4 in) insulation from the individual wires or use suppliedconnection cable

4. Insert the cable into the sensor through the cable entry

Fig. 3: Connection steps 5 and 6

5. Insert the wire ends into the terminals according to the wiring plan

Information:Solid cores as well as exible cores with cable end sleeves areinserted directly into the terminal openings.

In case of exible cores without end sleeves, press the terminal fromabove with a small screwdriver, the terminal opening is then free.When the screwdriver is released, the terminal closes again.

You can nd further information on the max. wire cross-section under

"Technical data/Electromechanical data"6. Check the hold of the wires in the terminals by lightly pulling on

them
