2 Product description

1 For your safety

1.1 Authorised personnel

All operations described in this operating

instructions manual must be carried out only by

trained specialist personnel authorised by the

plant operator.

During work on and with the device the required

personal protective equipment must always be

worn.

1.2 Appropriate use

The LFV 200 is a sensor for point level detec-

tion.

You can nd detailed information on the appli-

cation range of LFV 200 in chapter "Product

description".

1.3 Warning about incorrect use

Inappropriate or incorrect use of the instrument

can give rise to application-specic hazards,

e.g. vessel overll or damage to system compo-

nents through incorrect mounting or adjustment.

1.4 General safety instructions

This is a state-of-the-art instrument complying

with all prevailing regulations and guidelines.

The instrument must only be operated in a

technically awless and reliable condition. The

operator is responsible for the trouble-free

operation of the instrument.

During the entire duration of use, the user is

obliged to determine the compliance of the

necessary occupational safety measures with

the current valid rules and regulations and also

take note of new regulations.

The safety instructions in this operating instruc-

tions manual, the national installation standards

as well as the valid safety regulations and

accident prevention rules must be observed by

the user.

For safety and warranty reasons, any invasive

work on the device beyond that described in the

operating instructions manual may be carried

out only by personnel authorised by the manu-

facturer. Arbitrary conversions or modications

are explicitly forbidden.

The safety approval markings and safety tips on

the device must also be observed.

1.5 CE conformity

The protection goals of the EMC Directive

2004/108/EC (EMC) and the Low Voltage Direc-

tive 2006/95/EC (LVD) are fullled.

Conformity has been judged according to the

following standards:

EMC: EN 61326-1

(electrical instruments for control technology

and laboratory use - EMC requirements)

•

Emission: Class B

•

Susceptibility: Industrial areas

LVD: EN 61010-1

(safety regulations for electrical measurement,

control and laboratory instruments - part 1:

General requirements)

Scope of delivery

The scope of delivery encompasses:

•

LFV 200 point level switch

•

Test magnet

•

Documentation

– this operating instructions manual

– WRA certicate (optional)

2.2 Principle of operation

Application area

LFV 200 is a point level sensor with tuning fork

for point level detection.

It is designed for industrial use in all areas of

process technology and is used in liquids.

Function monitoring

The electronics module of LFV 200 conti-

nuously monitors via frequency evaluation the

following criteria:

•

Strong corrosion or damage on the tuning

fork

•

Loss of vibration

•

Line break to the piezo drive

If a malfunction is detected or in case of power

failure, the electronics takes on a dened

switching condition, i.e. the output is open (safe

15

condition).

Functional principle

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 integ-

rated electronics module and converted into a

switching command.

2.3 Storage and transport

Packaging

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 consists of cardboard. This

material is environment-friendly and recyclable.

Dispose of the packaging material via specia-

lised recycling companies.

3 Mounting

3.1 General instructions

Switching point

In general, LFV 200 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 diering from water.

Handling

Do not hold LFV 200 on the tuning fork. Bending

LFV 200 • Tuning Fork

3.2 Mounting instructions

Welded socket

For threaded versions of LFV 200 in combinati-

on with a mounting boss with O-ring in front and

welding marking.

LFV 200 with thread sizes ¾" and 1" have a

dened thread runout. This means that every

LFV 200 is in the same position after being

screwed in. Remove therefore the supplied at

seal from the thread of LFV 200. This at seal is

not required when using a welded socket with

front-ush seal.

Before welding, unscrew LFV 200 and remove

the rubber ring from the welded socket.

The welded socket is provided with a marking

(notch). For horizontal mounting, weld the so-

cket with the notch facing upward or downward;

in pipelines (DN 25 to DN 50) aligned with the

direction of ow.

1

Abb. 33: Marking on the welded socket

1 Marking

Adhesive products

In case of horizontal mounting in adhesive and

viscous products, the surfaces of the tuning fork

should be vertical. The position of the tuning

fork is indicated by a marking on the hexagon of

LFV 200. With this, you can check the position

of the tuning fork when mounting it.

In case of horizontal mounting in adhesive

and viscous products, the tuning fork should

protrude into the vessel to avoid buildup on the

tuning fork.

Flows

To make sure the tuning fork of LFV 200 gene-

rates as little resistance as possible to product

ow, mount the sensor so that the surfaces are

parallel to the product movement.

4 Connecting to power

supply

4.1 Preparing the connection

Note safety instructions

Always keep in mind the following safety inst-

ructions:

•

Connect only in the complete absence of

line voltage

4.2 Wiring plan

Contactless electronic switch

The instrument is used for direct control of

relays, contactors, magnet valves, warning

lights, horns etc. It must not be operated without

intermediately connected load, because the

electronic would be destroyed if connected

directly to mains. It is not suitable for connection

to low voltage PLC inputs. Domestic current is

temporarily lowered below 1 mA after switching

o the load so that contactors, whose holding

current is lower than the constant domestic

current of the electronics (3 mA), are reliably

switched o.

Examples for typical applications:

•

Load resistance at 24 V DC: 88 … 1800 Ω

•

Rated power, relay 253 V AC: > 2.5 VA

•

Rated power, relay 24 V AC: > 0.5 VA

For the plug version valve plug ISO 4400, stan-

dard cable with round wire cross-section can be

used. Cable diameter 4.5 … 7 mm, protection

IP 65.

5 Setup

5.1 Indication of the switching

status

The switching status of the electronics can be

checked via the signal lamp integrated in the

upper part of the housing.

5.2 Simulation

The LFV 200 has an integrated function for

simulation of the output signal which can be ac-

tivated magnetically. Please proceed as follows:

→

Hold the test magnet (accessory) against

the circle symbol with the label "TEST" on

the instrument housing

Abb. 37: 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.

Vorsicht:

It is absolutely necessary that you remo-

ve the test magnet from the instrument

housing after the simulation.

7 Dismounting

7.1 Dismounting steps

Warnung:

Before dismounting, be aware of dan-

gerous process conditions such as e.g.

pressure in the vessel, high temperatu-

res, corrosive or toxic products etc.

Take note of chapters "Mounting" and "Connec-

ting to power supply" and carry out the listed

steps in reverse order.

7.2 Disposal

The instrument consists of materials which can

be recycled by specialised recycling companies.

We use recyclable materials and have designed

the parts to be easily separable.
