3.2Principle of operation
LEVEL TRANSMITTER 8186 is a level sensor with cable or rod probe
for continuous level measurement.
It is designed for industrial use in all areas of process technology and
can be used in aggressive liquids.
High frequency microwave pulses are guided along a steel rope or a
rod.Upon reaching the product surface,the microwave pulses are
reflected.The running time is evaluated by the instrument and
outputted as distance.
Two-wire electronics 4…20 mA/HART for power supply and
measured value transmission over the same cable.
The supply voltage range can differ depending on the instrument
version.
The data for power supply are specified in chapter "Technical data".
3.3Operation
LEVEL TRANSMITTER 8186 can be adjusted with different adjust-
ment media:
lwith indicating and adjustment module
lWith a HART handheld
The entered parameters are generally saved in LEVEL TRANS-
MITTER 8186,optionally also in the indicating/adjustment module.
3.4Packaging,transport and storage
Your instrument was protected by packaging during transport.Its
capacity to handle normal loads during transport is assured by a test
according to DIN EN 24180.
The packaging of standard instruments consists of environment-
friendly,recyclable cardboard.For special versions,PE foam or PE foil
is also used.Dispose of the packaging material via specialised
recycling companies.

4.1General instructions
Make sure that all parts of the instrument exposed to the process,in
particular the sensor element,process seal and process fitting,are
suitable for the existing process conditions.These include above all
the process pressure,process temperature as well as the chemical
properties of the medium.
You can find the specifications in chapter "Technical data"or on the
type label.
Select an installation position you can easily reach for mounting and
connecting as well as later retrofitting of an indicating and adjustment
module.The housing can be rotated by 330°without the use of any
tools.You can also install the indicating and adjustment module in four
different positions (each displaced by 90°).
Before beginning the welding work,remove the electronics module
from the sensor.By doing this,you avoid damage to the electronics
through inductive coupling.
Use the recommended cables (see chapter "Connecting to power
supply")and tighten the cable gland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry.Rain and condensation water can thus drain off.This
applies mainly to outdoor mounting as well as installation in areas
where high humidity is expected (e.g.through cleaning processes)or
on cooled or heated vessels.

The reference plane for the measuring range of the sensors is the
lower edge of the flange.
Keep in mind that a min.distance must be maintained below the
reference plane and possibly also at the end of the probe -
measurement in these areas is not possible (dead band). Keep in mind
that the cable length cannot be used all the way to the end because
measurement in the area of the gravity weight is not possible.These
min.distances (dead bands)are listed in chapter "Technical data".
Keep in mind for the adjustment that the default setting for the
measuring range refers to water.
The process fitting must be sealed if there is gauge or low pressure in
the vessel.Before use,check if the seal material is resistant against
the measured product and the process temperature.
The max.permissible pressure is specified in chapter "Technical data"
or on the type label of the sensor.
4.2Mounting instructions
Mount LEVEL TRANSMITTER 8186 in such a way that the distance to
vessel installations or to the vessel wall is at least 300 mm (12 in).
During operation,the probe must not touch any installations or the
vessel wall.
In vessels with conical bottom it can be advantageous to mount the
sensor in the center of the vessel,as measurement is then possible
down to the lowest point of the vessel bottom.

To compensate the normal bias voltage loss due to the seal materials,
you have to use also disc springs in addition to the flange screws for
fastening PTFE plated flanges.
The flange screws of LEVEL TRANSMITTER 8186 must always be
tightened with a torque of approx.60 Nm(44 lbf ft)so that the PTFE
washer seals reliably.
If possible,avoid sockets.Mount the sensor flush with the vessel top.If
this is not possible,use short sockets with small diameter.
Higher sockets or sockets with a bigger diameter can generally be
used.They simply increase the upper dead band.Check if this is
relevant for your measurement.
In such cases,always carry out a gating out of false signals after
installation.You can find further information under "Setup procedure".
If a socket is absolutely necessary,then the use of a coax probe is
recommended.Due to the coax guide tube,sockets do not influence
measurement accuracy.

Standpipes or bypass tubes are normally metal tubes with a diameter
of 30 …200 mm (1.18 …7.87 in). In measurement technology such a
tube corresponds to a coax probe.It does not matter if the standpipe is
perforated or slotted for better mixing.Lateral inlets with bypass tubes
also do not influence the measurement.
Measuring probes can be mounted in bypass tubes up to DN 200.
The max.temperature is 250 °C(482 °F).
IfLEVEL TRANSMITTER 8186 is used in standpipes or bypass tubes,
contact with the tube wall should be avoided.We offer spacers as
accessories for fastening the probe in the middle of the tube.

Depending on the tube diameter or tube length,one or several spacers
can be mounted.With cable probes,the cable can also be strained to
avoid contact with the tube.
The max.temperature for the spacers is 250 °C(482 °F).
Keep in mind that buildup can form on the spacers.Strong buildup can
influence the measurement.
Microwaves can penetrate plastics.For process technical reasons,
plastic standpipes are problematic.If durability is no problem,then we
recommend the use of metal standpipes.

Note:
Measurement in a standpipe is not recommended for very adhesive
products.
Make sure that the probe is not subjected to strong lateral forces.
Mount LEVEL TRANSMITTER 8186 at a position in the vessel where
no disturbances,e.g.from filling openings,agitators,etc., can occur.

5Connecting to power supply
5.1Preparing the connection
Always keep in mind the following safety instructions:
lConnect only in the complete absence of line voltage
lIf overvoltage surges are expected,overvoltage arresters should
be installed
In hazardous areas you should take note of the appropriate
regulations,conformity and type approval certificates of the sensors
and power supply units.
Power supply and current signal are carried on the same two-wire
cable.The voltage supply range can differ depending on the
instrument version.
The data for power supply are specified in chapter "Technical data".
Provide a reliable separation between the supply circuit and the mains
circuits according to DIN VDE 0106 part 101.
Keep in mind the following additional influences on the operating
voltage:
lOutput voltage of the power supply unit can be lower under
nominal load (with a sensor current of 20.5mAor 22 mAin case of
fault message)
lInfluence of additional instruments in the circuit (see load values in
chapter "Technical data")
The instrument is connected with standard two-wire cable without
screen.If electromagnetic interference is expected which is above the
test values of EN 61326 for industrial areas,screened cable should be
used.
Use cable with round cross-section.Acable outer diameter of 5…9mm
(0.2…0.35 in)ensures the seal effect of the cable gland.If you are
using cable with a different diameter or cross-section,exchange the
seal or use a suitable cable gland.
If screened cable is necessary,connect the cable screen on both ends
to ground potential.In the sensor,the screen must be connected
directly to the internal ground terminal.The ground terminal on the
outside of the housing must be connected to the potential equalisation
(low impedance).
If potential equalisation currents are expected,the connection on the
processing side must be made via a ceramic capacitor (e.g.1nF,
1500 V). The low frequency potential equalisation currents are thus
suppressed,but the protective effect against high frequency interfer-
ence signals remains.
