3.1 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.

4.1 Connecting
The voltage supply and signal output are connected via the spring-
loaded terminals in the housing.
Connection to the display and adjustment module or to the interface
adapter is carried out via contact pins in the housing.
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.
Proceed as follows:
1. Unscrew the housing lid
2. If a display and adjustment module is installed, remove it by turn-
ing it slightly to the left
3. Loosen compression nut of the cable gland and remove blind
plug
4. Remove approx. 10 cm (4 in) of the cable mantle, strip approx.
1 cm (0.4 in) of insulation from the ends of the individual wires
5. Insert the cable into the sensor through the cable entry

6. Insert the wire ends into the terminals according to the wiring plan
Note:
Solid cores as well as exible cores with wire end sleeves are insert-
ed 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.
7. Check the hold of the wires in the terminals by lightly pulling on
them
8. Connect the shielding to the internal ground terminal, connect the
external ground terminal to potential equalisation

5.1 Insert display and adjustment module
The display and adjustment module can be inserted into the sensor
and removed again at any time. You can choose any one of four dier-
ent positions - each displaced by 90°. It is not necessary to interrupt
the power supply.
Proceed as follows:
1. Unscrew the housing lid
2. Place the display and adjustment module on the electronics in the
desired position and turn it to the right until it snaps in.
3. Screw housing lid with inspection window tightly back on
Disassembly is carried out in reverse order.

inspection glass is required.
5.2 Parameter adjustment - Quick setup
To quickly and easily adapt the sensor to the application, select the
menu item " Quick setup" in the start graphic on the display and
adjustment module.
Carry out the following steps in the below sequence.
You can nd " Extended adjustment" in the next sub-chapter.
Sensor address
In the rst menu item you have to enter a sensor address. The selec-
tion switches on the electronics module are preset to sensor address
126. This means that the sensor address can be changed via the
display and adjustment module.
Measurement loop name
In this menu item you assign a suitable measurement loop name.
Permitted are names with a maximum of 19 characters.

Application
In this menu item, you activate/deactivate the Secondary sensor for
the electronic dierential pressure and select the application. The ap-
plication comprises process pressure and level measurement.
Units
In this menu item you determine the adjustment and temperature
units of the instrument. Depending on the selected application in the
menu item " Application", dierent adjustment units are available.
Position correction
In this menu item you compensate the inuence of the installation
position of the instrument (oset) on the measured value.
Zero adjustment
In this menu item you carry out the zero adjustment for the process
pressure.
Enter the corresponding pressure value for 0 %.
Span adjustment
In this menu item you carry out the span adjustment for the process
pressure
Enter the corresponding pressure value for 100 %.
Position correction
In this menu item you compensate the inuence of the installation
position of the instrument (oset) on the measured value.
Max. adjustment
In this menu item you carry out the max. adjustment for level
Enter the percentage value and the corresponding value for the max.
level.
Min. adjustment
In this menu item you carry out the min. adjustment for level
Enter the percentage value and the corresponding value for the min.
level.

VEGABAR 87 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).
During adjustment, the pressure is entered e.g. for the level with full
and empty vessel, see following example:
2
1
100%
0%
2 m
(78.74
")
Fig. 8: Parameter adjustment example Min./max. adjustment, level measure-
ment
1 Min. level = 0 % corresponds to 0.0 mbar
2 Max. level = 100 % corresponds to 196.2 mbar
If these values are not known, an adjustment with lling levels of e.g.
10 % and 90 % is also possible. By means of these settings, the real
lling height is then calculated.
The actual product level during this adjustment is not important,
because the min./max. 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.
5.3 Parameter adjustment - Extended adjustment
For technically demanding measuring points, you can carry out
extended settings in " Extended adjustment".
The main menu is divided into ve sections with the following func-
tions:

6.1 Preparations
Make sure that the Bluetooth function of the display and adjustment
module is activated. For this, the switch on the bottom side must be
set to " On".

O
Fig. 9: Activate Bluetooth

On = Bluetooth active
O = Bluetooth not active
The security concept of Bluetooth operation absolutely requires that
the default setting of the sensor PIN be changed. This prevents unau-
thorized access to the sensor.
The default setting of the sensor PIN is " 0000". First of all you have
to change the sensor PIN in the adjustment menu of the sensor, e.g.
to " 1111":
1. Go to setup via the extended operation
2. Lock operation by changing sensor PIN
3. Enable operation by entering the sensor PIN once more

Sensor adjustment via the display/adjustment module or PACTware/
DTM by means of VEGACONNECT is thus released again. For ac-
cess (authentication) with Bluetooth, the changed PIN is still eective.
Note:
Bluetooth access can only be established if the current sensor PIN
diers from the default setting " 0000". It is possible both when the
adjustment is unlocked and when it is locked.
6.2 Connecting
Smartphone/Tablet
Start the adjustment app and select the function "Setup". The smart-
phone/tablet searches automatically for Bluetooth-capable instru-
ments in the area.
PC/Notebook
Start PACTware and the VEGA project assistant. Select the device
search via Bluetooth and start the search function. The device auto-
matically searches for Bluetooth-capable devices in the vicinity.
The message " Instrument search running" is displayed. All devices
found are listed in the operating window. The search is automatically
continued continuously.
Select in the device list the requested device.The message " Con-
necting" is displayed.
For the rst connection, the operating device and the sensor must
authenticate each other. After successful authentication, the next con-
nection functions without authentication.
For authentication, enter in the next menu window the 4-digit sensor
PIN.
6.3 Sensor parameter adjustment
The sensor parameterization is carried out via the adjustment app on
the smartphone/tablet or the DTM on the PC/notebook.
