2.7Safety instructions for Exareas

Please note the Ex-speciﬁc safety information for installation

and operation in Ex areas.These safety instructions are part of

the operating instructions manual and come with the Ex-

approved instruments.

2.8Manufacturer declaration

In conformity with DIN EN 60079-14/2004,para.5.2.3,point

c1,VEGAWAVE 62 is suitable for use in zone 2.

The operator must use the instrument as it was intended to be

used and follow the speciﬁcations of the following documents:

lthis operating instructions manual

lthis manufacturer declaration (24646)

lthe applicable installation regulations

Max.increase of the surface temperature during operation:

40 K(individual components in the instrument)

With an ambient temperature of 70 °C(158 °F)on the housing

and a process temperature of 70 °C(158 °F), the max.ambient

temperature during operation is 110 °C(230 °F).

Measures to maintain explosion protection during operation:

lOperate the instrument in the range of the speciﬁed

electrical limit values.Permissible supply voltage:see

"Technical data"

lMount and operate the instrument in such a way that no

ignition danger is expected by electrostatic charges.The

process ﬁtting,the plastic-coated/covered probe part or the

housing are made of electrically non-conductive plastic

(depending on the version).

lMake sure that the seal is mounted correctly between

lower part of the housing and cover.Screw the cover on

tightly.

lMake sure there is no explosive atmosphere present if you

intend to operate the instrument with opened cover

6VEGAWAVE 62 --contactless electronic switch

For your safety

32251-EN-070117

lMake sure that the cable gland is tight and strain-relieved.

The outer diameter of the connection cable must be

adapted to the cable gland.Tighten the pressure screw of

the cable gland carefully.

lCover unused openings for cable glands tightly

lMount the instrument in such a way that the sensor cannot

touch the vessel wall or vessel installations.Keep in mind

the inﬂuence of product movement in the vessel.

lThe surface temperature of the housing must not exceed

the ignition temperature of the surrounding explosive

atmosphere

This instrument was assessed by a person who fulﬁls the DIN

EN 60079-14 requirements.

2.9Environmental instructions

Protection of the environment is one of our most important

duties.That is why we have introduced an environment

management system with the goal of continuously improving

company environmental protection.The environment man-

agement system is certiﬁed according to DIN EN ISO 14001.

Please help us fulﬁl this obligation by observing the environ-

mental instructions in this manual:

Product description

32251-EN-070117

It is designed for industrial use in all areas of process

technology and is preferably used for bulk solids.

Typical applications are overﬁll and dry run protection.Thanks

to its simple and robust measuring system,VEGAWAVE 62 is

virtually unaﬀected by the chemical and physical properties of

the bulk solid.

It functions even when exposed to strong external vibration or

changing products.

Solid detection in water

IfVEGAWAVE 62 was ordered for detection of solids in water,

the tuning fork is adjusted to the density of water.In the air or

when covered by water (density:1g/cm³/0.036 lbs/in)

VEGAWAVE 62 signals "uncovered".Only if the vibrating

element is also covered with solids (e.g.sand,sludge,gravel

etc.) will the sensor signal "covered".

Fault monitoring

The electronics of VEGAWAVE 62 continuously monitors the

following criteria:

lCorrect vibrating frequency

lLine break to the piezo drive

If one of the stated malfunctions is detected or in case of

power failure,the electronics takes on a deﬁned switching

condition,i.e.the contactless electronic switch opens (safe

condition).

The tuning fork is piezoelectrically energised and vibrates at its

mechanical resonance frequency of approx.150 Hz.When the

tuning fork is submerged in the product,the vibration

amplitude changes.This change is detected by the integrated

oscillator and converted into a switching command.

VEGAWAVE 62 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,aPLC,a pump etc.).

The data for power supply are stated in chapter "Technical

data"in the "Supplement".

3.3Operation

With the factory setting,products with a density of >0.02 g/cm³

(0.0008 lbs/in³)can be measured.The instrument can also be

adapted to products with lower density >0.008 g/cm³

(0.0003 lbs/in³).

On the electronics module you will ﬁnd the following indicating

and adjustment elements:

lsignal lamp for indication of the switching condition (green/

red)

lpotentiometer for adaptation to the product density

lMode switch for selecting the switching condition (min./

max.)

3.4Storage and transport

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 environ-

ment-friendly,recyclable cardboard.In addition,the sensor is

provided with a protective cover of cardboard.For special

versions PE foam or PE foil is also used.Dispose of the

packaging material via specialised recycling companies.

lStorage and transport temperature see "Supplement -

Technical data -Ambient conditions"

lRelative humidity 20 …85 %
