observance of standard regulations and guidelines.The user

must take note of the safety instructions in this operating

instructions manual,the country-speciﬁc installation standards

(e.g.the VDE regulations in Germany)as well as all prevailing

safety regulations and accident prevention rules.

2.5CE conformity

VEGACAP 65 is in CE conformity with EMC (89/336/EWG)

and LVD (73/23/EWG).

Conformity has been judged acc.to the following standards:

lEMC:

2.6Safety information for Ex areas

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.

2.7Manufacturer declaration

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

c1,the capacitive probe VEGACAP 65 is suitable for use in

zone 2.

The operator must use the instrument correctly and follow the

speciﬁcations of the following documents:

lthis operating instructions manual

lthis manufacturer declaration (24643)

lthe corresponding 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 the explosion protection during oper-

ation:

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 that there is no explosive atmosphere,if you

want to operate the instrument with open cover

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

For your safety

30017-EN-060223

lMount the instrument in such a position that the sensor

cannot touch the vessel wall or vessel installations.Keep

the inﬂuences of product movements in the vessel in mind.

lThe surface temperature on the housing must not exceed

the ingnition temperature of the concerned explosive

atmosphere

This instrument was judged by a person that fulﬁls the

requirements acc.to DIN EN 60079-14.

2.8Environmental 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 acc.to DIN EN ISO 14001.

Please help us fulﬁl this obligation by observing the environ-

mental instructions in this manual:

lChapter "Storage and transport"

lChapter "Disposal"

3.2Principle of operation

VEGACAP 65 is a level sensor with capacitive electrode for

level detection.

VEGACAP 65 is very rugged and maintenance-free and can

be used in all areas of industrial process technology.

Probes such as VEGACAP 65 can be used in solids and in

non-conductive liquids.

Typical applications are overﬁll and dry run protection.

The capacitive measuring principle places no special require-

ments on installation.Hence,many diﬀerent applications can

be equipped with VEGACAP 65.

The instrument can also be used problem-free in adhesive

products.

The probe,the measured product and the vessel wall form an

electrical capacitor.The capacitance is inﬂuenced by three

main factors.

Fig.2:Functional principle -Plate capacitor

1Distance between the electrode surfaces

2Size of the electrode surfaces

3Type of dielectric between the electrodes

The probe and the vessel wall are the capacitor plates.The

measured product is the dielectric.Due to the higher dielectric

constant (DK value)of the product compared to air,the

capacitance increases as the probe is gradually covered.

The capacitance change is converted by the oscillator into a

switching command.

Product description

30017-EN-060223

VEGACAP 65 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 exact range of the supply voltage is speciﬁed in the

"Technical data"in the "Supplement".

3.3Adjustment

The probe can be adapted to the dielectric constant of the

product directly on the electronics module.

Aswitching command can be triggered when the probe is

covered or laid bare.

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 switching point adaptation

lDIL switch for measuring range selection

lDIL switch for mode adjustment

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 acc.to DIN 55439.

The packaging of standard instruments consists of environ-

ment-friendly,recyclable 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 %
