Safety instructions

VA 570 English V1.19 Page 6 of 44

3 Safety instructions

Please check whether this manual corresponds with the device type.

Please attend to all notes indicated in this instruction manual. It contains essential information,

which has to be followed during installation, operation and maintenance. Therefore this

instruction manual has to be read categorically by the technician as well as by the responsible

user/qualified personnel before installation, initiation and maintenance

Regional and national regulations respectively, have to be observed in addition to this

instruction manual if necessary.

This instruction manual has to be available at any time at the operation site of the DS 500.

Ensure that the VA 570 operates within the permissible and listed limits on the nameplate.

Otherwise there is a risk to human and material, and it may occur functional and operational

disturbances

In case of any obscurities or questions with regard to this manual or the instrument please

contact CS Instruments GmbH.

Warning!

Risk of injury in case of inadequate qualification!

Improper handling can result in significant personal injury and damage.

All activities described in this operating instructions manual must be carried out only by qualified

personnel qualifications described below.

Professionals (Technical staff)

The technical staff is based on his education/training, his knowledge of measurement and control

technology as well of the local regulations, standards and guidelines in the position to do the work as

described and to identify the possible hazards.

Special working conditions require further appropriate knowledge, e.g. of aggressive media.

Caution!

Malfunction of VA 570

Faulty installation and insufficient maintenance may lead to malfunctions of the Va 570, which may

affect the display and open to misinterpretation.

Danger!

Inadmissible operating parameters!

By exceeding or falling short of limits there is a risk for people and material, in addition there

may occur further functional and operational disturbances.

Measures:

•Make sure that the VA 570 operates only within the permissible and listed limits on the nameplate

•Ensure the operation within the performance data of VA 570 in connection with the application

•Do not exceed the admissible storage and transportation temperature.

Additional safety information:

•When installing and operating the relevant national regulations and safety rules must also be

observed.

In gas hazardous areas (explosive media) only the version VA 570 EX must be used.

When using the Flow-/ Consumption sensors VA 570 Ex in gas hazardous areas the special

requirements specified in the Ex documentation must be observed.

Safety instructions

VA 570 English V1.19 Page 7 of 44

3.1 Intended Use

The instrument described in this manual is exclusively to use for measuring the thermal mass flow of

gases. At the same time, the gas temperature is measured too.

The VA 570 can be configured for measuring a predetermined range of pure gases or of

gas mixtures.

Consumption measurement of gases such as Air, oxygen, nitrogen, carbon dioxide, argon, etc.

and with ATEX approval explosive gases such as natural gas, methane, propane and hydrogen.

Improper or incorrect use the operational reliability will be canceled. The manufacturer is not liable for

any damage resulting by improper or incorrect use.

3.2 Installation and commissioning

•Installation, electrical installation, commissioning, operation and maintenance of the device

must only be carried by qualified personnel, which were authorized by the plant operator.

The personnel must read the operating instructions, understand and follow the instructions.

•If carrying out welding work on the pipeline the grounding of the welding unit is not allowed to

be done over the VA570 itself.

•The installer has to ensure that the VA 570 is connected according to the electrical

connection diagrams properly. The sensor must be grounded, unless special protective

measures have been taken (e.g. galvanically isolated power supply)

•The existing/ applicable national regulations governing opening and repair of the device have

to be applied.

•When using the VA 570 (ATEX Version) hazardous areas, in addition with the standard

manual a separate Ex documentation is enclosed. The installation instructions and connection

values indicated in these must also be observed.

•The device fulfills the general safety requirements in accordance with EN 61010-1,

the EMC requirements of IEC / EN 61326 and NAMUR recommendation NE 43.
