3.2 Principle

of operation

LEVEL SWITCH 8110 is a point level sensor with tuning fork for level
detection.

It is designed for industrial use in all areas of process technology and
can be used in liquids.

Typical applications are overfill and dry run protection. With a tuning
fork of only 38 mm length, LEVEL SWITCH 8110 can be also mounted
e.g. in pipelines from DN 25. The small tuning fork allows use in
vessels, tanks and pipes. Thanks to its simple and robust measuring
system, LEVEL SWITCH 8110 is virtually unaffected by the chemical
and physical properties of the liquid.

It functions even under difficult conditions such as turbulence, air
bubbles, foam generation, buildup, strong external vibration or
changing products.

Function monitoring

The electronics module of LEVEL SWITCH 8110 continuously
monitors via frequency evaluation the following criteria:

l Strong corrosion or damage on the tuning fork
l Loss of vibration
l Line break to the piezo drive

If a malfunction is detected or in case of power failure, the electronics
takes on a defined switching condition, i.e. the output is open (safe
condition).

The tuning fork is piezoelectrically energised and vibrates at its
mechanical resonance frequency of approx. 1100 Hz. When the tuning
fork is submerged in the product, the frequency changes. This change
is detected by the integrated electronics module and converted into a
switching command.

LEVEL SWITCH 8110 is a compact instrument, i.e. it can be operated
without external evaluation system. The integrated electronics
evaluates the level signal and outputs a switching signal. With this
switching signal, a connected device can be operated directly (e.g. a
warning system, a pump etc.).

The data for power supply are specified in chapter "Technical data".

3.3 Operation

The switching status of LEVEL SWITCH 8110 can be checked with
closed housing (signal lamp). Products with a density > 0.7 g/cm³
(0.025 lbs/in³) can be detected.

3.4 Storage and transport

Your

instrument was protected by packaging during transport. Its

capacity to handle normal loads during transport is assured by a test
based on ISO 4180.

The packaging of standard instruments consists of environment­friendly, recyclable cardboard. For special versions, PE foam or PE foil
is also used. Dispose of the packaging material via specialised
recycling companies.

Transport must be carried out under consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.

The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or
concealed defects must be appropriately dealt with.

4 Mounting

4.1 General

instructions

Make sure that all parts of the instrument coming in direct contact with
the process, especially the sensor element, process seal and process
fitting, are suitable for the existing process conditions, such as process
pressure, process temperature as well as the chemical properties of
the medium.

You can find the specifications in chapter "Technical data" and on the
nameplate.

In general, LEVEL SWITCH 8110 can be installed in any position. The
instrument only has to be mounted in such a way that the tuning fork is
at the height of the desired switching point.

Keep in mind that the swichting point can vary dependent on the
installation position.

The switching point refers to the medium water (1 g/cm³/0.036 lbs/in³).
Please keep in mind that the switching point of the instrument shifts

when the medium has a density differing from water.

Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.

You can give your LEVEL SWITCH 8110 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 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.

The vibrating level switch is a measuring instrument and must be
treated accordingly. Bending the vibrating element will destroy the
instrument.

Warning:

Th

e housing must not be used to screw the instrument in! Applying

tightening force can damage internal parts of the housing.

Use the hexagon above the thread for screwing in.

4.2 Instructions for installation

In case of horizontal mounting in adhesive and viscous products, the
surfaces of the tuning fork should be vertical in order to reduce buildup
on the tuning fork. The position of the tuning fork is indicated by a
marking on the hexagon of LEVEL SWITCH 8110. With this, you can
check the position of the tuning fork when screwing it in. When the
hexagon touches the seal, the thread can still be turned by approx. half
a turn. This is sufficient to reach the recommended installation
position.

In adhesive and viscous products, the surfaces of the tuning fork
should protrude into the vessel to avoid buildup. Therefore sockets for
flanges and mountings bosses should not exceed a certain length.

If LEVEL SWITCH 811

0 is mounted in the filling stream, unwanted

false measurement signals can be generated. For this reason, mount
LEVEL SWITCH 8110 at a position in the vessel where no

disturbances, e.g. from filling openings, agitators, etc., can occur.

To make sure the tuning fork of LEVEL SWITCH 8110 generates as
little resistance as possible to product flow, mount the sensor so that
the surfaces are parallel to the product movement.

5.1 Prepa

ring the connection

Always keep in mind the following safety instructions:

l Connect only in the complete absence of line voltage

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. Depending on the plug
connection, you have to select the outer diameter of the cable
respectively so that the seal effect of the cable gland is ensured.

l Valve plug ISO 4400, ø 4.5 … 7 mm
l Valve plug ISO 4400 with IDC crimping technology, ø 5.5 … 8 mm

Use cable with a round wire cross section and tighten the cable gland.

When mounting outdoors, on cooled vessels or in moist areas in which

cleaning is made with steam or high pressure, the sealing of the cable
gland is very important.

6 Setup

6.1 Indicati

on of the switching status

The switching status of the electronics can be checked via the signal
lamps (LEDs) integrated in the upper part of the housing.

The signal lamps have the following meaning:

l Green lights - voltage supply connected
l Yellow lights - vibrating element covered
l Red lights briefly - function test during instrument start (for 0.5 s)
l Red lights - shortcircuit or overload in the load circuit (sensor

output high-impedance)

l Red flashes - Error on the vibrating element or the electronics

(sensor output high impedance)

6.2 Simulation

The LEVEL SWITCH 8110 has an integrated function for simulation of
the output signal which can be activated magnetically. Please proceed
as follows:

à Hold the test magnet (accessory) against the circle symbol with

the label "TEST" on the instrument housing

Fig. 11: Simulation of

the output signal

The test magnet changes the current switching condition of the
instrument. You can check the change on the signal lamp. Please note
that all connected device are activated during the simulation.

If LEVEL SWITCH 8110 does not switch over after several tests with
the test magnet, you have to check the plug connection and the
connection cable and try it again. If there is no switching function, the
electronics will be defective. In this case you have to exchange the
electronics or return the instrument to our repair department.
