equipment must always be worn.
orised personnel
2.2 Appropriate use
VEGADIS 175 is a digital indicating instrument for 4 … 20 mA circuits.
2.3 Warning about incorrect use
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.
2.4 General safety instructions
This is a high-tech instrument requiring the strict observance of
standard regulations and guidelines. The user must take note of the
safety instructions in this operating instructions manual, the countryspecific installation standards as well as all prevailing safety
regulations and accident prevention rules.
The instrument must only be operated in a technically flawless and
reliable condition. The operator is responsible for trouble-free
operation of the instrument.
During the entire duration of use, the user is obliged to determine the
compliance of the necessary occupational safety measures with the
current valid rules and regulations and also take note of new
regulations.
2.5 Safety label on the instrument
The safety approval markings and safety tips on the device must be
observed.
2.6 CE conformity
The device fulfills the legal requirements of the applicable EC
guidelines. By affixing the CE marking, we confirm successful testing
of the product.

2 For your safety
The instrument is designed for use in an industrial environment.
Nevertheless, elec
and radiated emissions must be taken into account, as is usual with a
class A instrument according to EN 61326-1. If the instrument is used
in a different environment, its electromagnetic compatibility with other
devices must be ensured by suitable measures.
tromagnetic interference from electrical conductors
2.7 Environmental 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

3.2 Principle of operation
VEGADIS 175 is a digital indicating instrument for measured value
indication in 4 … 20 mA circuits. The measured value is displayed via
the LC display, the digital indication can be scaled. The instrument is
suitabe for front panel mounting.
VEGADIS 175 is looped directly into the 4 … 20 mA circuits and
requires no separate external energy. Connection is carried out via
screw terminals in the housing.
3.3 Operation
Adjustment is carried out via keys in the front plate of the instrument.
3.4 Packaging, 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 environmentfriendly, recyclable cardboard. For special versions, PE foam or PE foil
is also used. Dispose of the packaging material via specialised
recycling companies.

7.2 Remove interferences
VEGADIS 175 offers maximum reliability. Nevertheless, faults can
occur during operation. These may be caused by the following, e.g.:
l Sensor
l Process
l Voltage supply
l Signal processing
The first measure is to check the sensor output signal according to the
operating instructions manual of the respective sensor. In many cases
the reasons can be determined this way and faults rectified. System
errors of VEGADIS 175 are displayed via the system error message of
the following chart:
Connect a handheld multimeter in the suitable measuring range
according to the wiring plan.

8.2 Disposal
The indicating and adjustment module consists of materials which can
recycled by specialised recycling companies. We have purposely
designed the components to be easily separable.
WEEE directive 2002/96/EG
This indicating and adjustment module is not subject to the WEEE
directive 2002/96/EG and the respective national laws (in Germany, e.
g. ElektroG). Pass the indicating and adjustment module directly on to
a specialised recycling company and do not use the municipal
collecting points. These may only be used for privately used products
according to the WEEE directive.
Correct disposal avoids negative effects on humans and the environment and ensures recycling of useful raw materials.
Materials: see chapter "Technical data"
If you have no way to dispose of the old instrument properly, please
contact us concerning return and disposal.
