3 Remarks
3.1 Designation of the Remarks
If possible remaining dangers emerge during the operation with VS3, this will be indicated by the following
symbols in this operation manual:
Note:
Important points to consider
3.2 Safety Notes
3.2.1 General References
The enclosed operating instruction is intended for technically qualified personnel who have corresponding
knowledge in the field of measurement and industrial process & control technology.
The precise information about all safety notes contained in this operation manual and warnings, as well
as its perfect technical implementation are precondition for the safe installation, the initiation, the secure
operation and the maintenance of Lorenz Messtechnik GmbH technology devices. For this purpose it is
absolutely necessary that all measures are carried out by qualified personnel. All persons concerned with
the project planning, installation and service of Lorenz Messtechnik GmbH devices, must be familiar to
the security concepts in automatic control and should be qualified in this sense.
For clarity reasons, the enclosed operating instruction cannot represent complete details in all
conceivable cases of applications for the handling of Lorenz Messtechnik GmbH devices. Further, we
cannot consider the entire types of installation, handling and maintenance. If you wish further information
or if special problems occur, which were not, or not at length represented in this operating instruction,
contact us, please.
The oblivion of the safety notes can and will lead to material damages, body injuries and death.
Lorenz Messtechnik GmbH devices may only be operated in accordance with the applications
described in this operation manual. Built-in devices may only be operated in appropriate
installations.
With the connection and the initiation of the device, the customer accepts the general sale and delivery
conditions of Lorenz Messtechnik GmbH. Further, he accepts eventually incomplete operation manuals.
The information described is without guarantee. Errors and changes are reserved.
3.2.2 Intended Purpose, Improper Usage
A Lorenz Messtechnik GmbH device is used for displaying, processing and controlling or regulation of
processes. It shall not be used as the only tool for the prevention of dangerous states to machines and
plants. Machines and plants must be constructed in such a way, that erroneous states cannot lead to a
dangerous situation for the staff (e.g. by independent limit switches, mechanical locking devices). It must
be guaranteed in particular that device-operating errors, its malfunction or its breakdown do not lead to
great property damages or danger for the staff. Consequently, the device then can be used to prevent the
machine or the technical installations from error conditions.
It is also important that the use of devices does not endanger precautions for the safety of technical
installations.
Emergency-off settings must remain effective in all operation modes.

3.2.3 Installation Notes
Lorenz Messtechnik GmbH devices must be installed and connected by compliance with the relevant
DIN- and VDE-norms. They must be installed in such manner that an unintentional use is adequately
excluded. The corresponding hardware and software safety precautions are to be observed in such
manner that an interruption of the supply and signal cables cannot lead to an undefined or dangerous
state. Supply and signal cables must be installed in such way, that disturbing signals (e.g. inductive or
capacitive intersperses) will not cause derogations to the function of Lorenz Messtechnik GmbH devices.
3.2.4 Disturbance, Maintenance and Repair Notes
The devices do not contain parts which can be maintained on the customer side. Repairs shall be carried
out by Lorenz Messtechnik GmbH exclusively.
If assuming that a safe operation of the device is not possible anymore, it must be closed down and
protected against unintentional handling immediately. This, in particular, applies:
If the device shows visible damages
If the device is no longer operative
If parts of the device are loose or slack
If the connection cables show visible damages
Furthermore, we point out that all obligations of Lorenz Messtechnik GmbH exclusively result from the
respective sales contract in which the guarantee has been conclusively settled.
