4.1 General instructions
TheeldhousingoftheVEGAMET861isequallysuitableforoutdoor
or indoor installation due to its degree of protection IP66/IP67 and
Type 4X. The standard version is designed for wall mounting. A
mounting adapter for pipe mounting is available as an option.
The instrument is suitable for standard and extended ambient condi-
tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used
indoors as well as outdoors.
Avoid direct sunlight or use the optionally available sun shade.
Makesurethattheenvironmentalandambientconditionsspeciedin
chapter "Technical data" are maintained.
Protect your instrument against moisture ingress through the following
measures:
• Use the recommended connection cable (see chapter "Connect-
ing to power supply")
• Tighten the cable gland
• Mount the instrument in such a way that the cable glands point
downward
• Loop the connection cable downward in front of the cable gland
This applies mainly to outdoor installations, in areas where high
humidity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
The visible area of the front panel must be protected from knocks,
otherwise water can penetrate through breaking of the front foil. In this
case, protection against accidental contact can no longer be ensured.
Caution:
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.
The pressure compensation for the housing is realized via a breather
element.
Note:
Make sure that the pressure equalization element is always free of
buildup during operation. A high-pressure cleaner may not be used
for cleaning.

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 instrument belongs to protection class I, hence connection of an
earth conductor is required.
Use cable with round cross section.The cable diameter must be
suitableforthecableglandusedtoensurethesealeectofthecable
gland (IP protection).
The voltage supply 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 opera-
tion with HART 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 mind1).
When connecting HART sensors, the supplied ground terminal must
be attached to the outside of the housing. To do this, carefully remove
the pre-embossed opening (ø 6 mm) on the lower side of the device
with a suitable tool and screw in the ground terminal.
Connect the cable screening on both ends to ground potential. In the
sensor/VEGAMET 861, the shielding must be connected directly to
the internal ground terminal.The ground terminal on the outside of the
sensor housing/VEGAMET 861 must be connected to the potential
equalisation (low impedance).
If potential equalisation currents are expected, the screen connection
on the side of VEGAMET 861 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eectagainsthighfrequency
interference signals remains.

Warning:
Indeliverystatus,allopeningsarettedwithdustprotectioncaps.
These caps are only for protection during transport and are not suit-
able for protection during operation! Instead, all openings must be
closed with cable glands/blind plugs.
Cable glands, NPT adapters or blind plugs that are not included in
the scope of delivery must meet the applicable requirements in order
to ensure the environmental compatibility of the housing. For outdoor
applications, the weather resistance of the accessories to be used
must be taken into account.The cable glands, NPT adapters and
blind plugs must have a metric thread M20 to be compatible with the
threaded openings of the metal plate in the housing.
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 861 can also be looped into the existing
circuit like a normal ammeter.
Note:
With a VEGAMET 861 in Ex version, the passive input is not available.
5.3 Digital input mode active/passive
Through the selection of the terminals, you can choose between ac-
tive and passive operation of the digital input.
• At the active input the controller provides a power supply. This
operating mode is intended for the connection of potential-free
switching contacts. An external voltage must not be supplied.
• At the passive input a voltage must be supplied via the switch-
ing contact.This input is intended for the connection of switching
contacts with their own, separate power supply. The permissible
voltagespecicationsforthiscanbefoundinthetechnicaldata.
With the application "Pump control", the digital input can be used for
pump monitoring.

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.
