4.1 General instructions for use of the instrument
Protect your instrument against moisture ingress through the following
measures:
• Use a suitable connection cable (see chapter " Connecting to
power supply")
• Tighten the cable gland or plug connector
• Lead the connection cable downward in front of the cable entry or
plug connector
This applies mainly to outdoor installations, in areas where high
humidity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
Note:
Make sure that during installation or maintenance no moisture or dirt
can get inside the instrument.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.

With the following instruments a blind plug is installed instead of the
lter element:
• Instruments in protection IP66/IP68 (1 bar) - ventilation via capillar-
ies in non-detachable cable
• Instruments with absolute pressure
4.3 Combination Primary/Secondary sensor
In principle, any sensor combination within the instrument series is
allowed. The following requirements must be fullled:
• Conguration of the sensor suitable for electronic dierential pres-
sure
• Pressure type is identical for both sensors, i.e. relative pressure/
relative pressure or absolute pressure/absolute pressure

VEGABAR 86 • Secondary sensor for electronic dierential pressure
46334-EN-220624
• Primary Device measures the higher pressure
• Measurement setup as shown in the following chapters
The measuring range of each sensor is selected such that it ts the
measuring loop. For this, the max. recommended turn down must be
noted. See chapter " Technical data". It is absolutely necessary the
the measuring ranges of Primary and Secondary Device correspond.
Measurement result = Measured value of Primary (total pres-
sure) - measured value of Secondary (static pressure)
Depending on the application, individual combinations can result, see
following examples:

5.1 Connecting
The connection to the Primary Device is carried out through spring-
loaded terminals in the respective housing. For this, use the supplied,
confectioned cable. Solid cores as well as exible cores with cable
end sleeves are inserted directly into the terminal openings.
In case of exible cores without end sleeves, press the terminal from
above with a small screwdriver, the terminal opening is then free.
When the screwdriver is released, the terminal closes again.
Information:
The terminal block is pluggable and can be removed from the
electronics. To do this, lift the terminal block with a small screwdriver
and pull it out. When reinserting the terminal block, you should hear it
snap in.
You can nd further information on the max. wire cross-section under
" Technical data - Electromechanical data".
Proceed as follows:
1. Unscrew the housing lid
2. Loosen compression nut of the cable gland and remove blind
plug
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 supplied
connection 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
6. Check the hold of the wires in the terminals by lightly pulling on
them

VEGABAR 86 always measures pressure independently of the pro-
cess variable selected in the menu item " Application". To output the
selected process variable correctly, an allocation of the output signal
to 0 % and 100 % must be carried out (adjustment).
For the application " Interface", the hydrostatic pressure e.g. with
interface "Min." and interface "Max." is entered for the adjustment.
The position of the interface is detected by the Secondary sensor.

If these values are not known, an adjustment with interface layers of
for example 10 % and 90 % is also possible. By means of these set-
tings, the layer of the actual interface is then calculated.
The real product level during the adjustment is not important, be-
cause the min./max. interface adjustment is always carried out without
changing the product level. These settings can be made ahead of
time without the instrument having to be installed.

For technically demanding measuring points, you can carry out
extended settings in " Extended adjustment".
