2.5Safety label on the instrument
The safety approval markings and safety tips on the device must be
observed.
2.6CE conformity
This device fulfills the legal requirements of the applicable EC
guidelines.By attaching the CE mark,VEGA provides a confirmation
of successful testing.You can find the CE conformity declaration in the
download area of www.vega.com.
2.7Fulfillment of NAMUR recommendations
With respect to compatibility,the NAMUR recommendation NE 53 is
fulfilled.This applies also to the corresponding indicating and
adjustment components.VEGA instruments are generally upward and
downward compatible.
lSensor software to DTM VEGACAL 62
lDTM VEGACAL 62 for adjustment software PACTware
lIndicating and adjustment module for sensor software
The parameter adjustment of the basic sensor functions is independ-
ent of the software version.The range of available functions depends
on the respective software version of the individual components.
2.8Safety instructions 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.
2.9Environmental 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 management system is certified according to DIN
EN ISO 14001.
Please help us fulfil this obligation by observing the environmental
instructions in this manual:
lChapter "Packaging,transport and storage"
lChapter "Disposal"

serial number on the inside of the instrument.
3.2Principle of operation
VEGACAL 62 is a level sensor with partly insulated probe for
continuous level measurement.
The electronics functions according to the admittance principle
(phase-selective admittance processing).
It is designed for industrial use in all areas of process technology and
can be applied in all areas of industrial process measurement.
Partly insulated probes such as VEGACAL 62 are preferably used in
bulk solids.
However,the probe can also be used in non-conductive liquids such
as e.g.oil.
Probe,measured product and vessel wall form an electrical capacitor.
The capacitance is influenced by three main factors.

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.

30025-EN-090603

The capacitance as well as the resistance change are converted by
the electronics module into a level-proportional signal.
Power supply via the Profibus DP/PA segment coupler or VEGALOG
571 EP cards.Atwo-wire cable according to Profibus specification
serves as carrier of both power and digital data transmission for
multiple sensors.The instrument profile of VEGACAL 62 corresponds
to profile specification version 3.0.
The GSD (instrument master files)and bitmap files necessary for
planning your Profibus-DP-(PA)communication network are available
from the download section on the VEGA homepage www.vega.com
under "Services -Downloads -Software -Profibus".There you can
also find the appropriate certificates.In a PDM environment,an EDD
(Electronic Device Description)is also required to enable the full range
of sensor functions (also available as a download).A CD with the
appropriate files can be ordered via e-mail under [e-mail] or
by phone from one of the VEGA agencies under the order number
"DRIVER.S".
The backlight of the indicating and adjustment module is powered by
the sensor.Prerequisite is a certain level of operating voltage.
The data for power supply are specified in chapter "Technical data".
The optional heating requires its own operating voltage.You can find
details in the supplementary instructions manual "Heating for indicat-
ing and adjustment module".
This function is generally not available for approved instruments.
3.3Operation
VEGACAL 62 can be adjusted with different adjustment media:
lwith indicating and adjustment module
lwith the suitable VEGA DTM in conjunction with an adjustment
software according to the FDT/DTM standard,e.g.PACTware and
PC
lwith the adjustment program PDM
3.4Packaging,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 environment-
friendly,recyclable cardboard.For special versions,PE foam or PE foil
is also used.Dispose of the packaging material via specialised
recycling companies.
