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:

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.
