2For your safety

2.1Authorised 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

protection equipment must always be worn.

2.2Appropriate use

The cable shortening set is used to shorten VEGAVIB sensors

in cable version (VEGAVIB 62).

2.3Warning about misuse

Inappropriate or incorrect use of the instrument can give rise to

application-speciﬁc hazards,e.g.vessel overﬁll or damage to

system components through incorrect mounting or adjustment.

2.4Environmental 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:

3.1Conﬁguration

The scope of delivery encompasses:

lCable shortening set

lDocumentation

-this operating instructions manual

3.2Principle of operation

The cable shortening set is a set of parts used to shorten a

VEGAVIB 62 in cable version PUR (temperature range

-40°…+150°C).

The cable shortening set can be used,e.g., when the sensor

has to be guided through a narrow tube.

The cable shortening set must not be used if the sensor is

deployed for solids detection in water.

The cable of the sensor consists of a suspension cable,the

electrical cables and an outer insulation.

3.3Packaging,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 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.

Transport must be carried out under consideration of the notes

on the transport packaging.Nonobservance of these instruc-

tions 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.
