Safety
5.1
General
Before commissioning, check the device and all accessories supplied. Before commissioning,
please read the operating instructions. Ensure that the instrument is suitable for your application.
The pressure transmitter may no longer be used when the label becomes
illegible.
The pressure transmitters may only be operated using the battery type specified in chapter 4.1.
The seals and gaskets need to be checked to see that they function properly prior to mounting and
at regular intervals in keeping with the climatic conditions and the influence of the media, and to be
changed as needed. Replacement seals and gaskets can be obtained from HYDAC
ELECTRONIC GMBH. (Standard seal see Technical Data) This check is to be performed at least
every three years.
Apart from the replaceable seals and gaskets or replaceable batteries, the pressure transmitter
does not have any further components requiring maintenance by the user. Apart from opening the
battery cover, the user may not open the device.
It is imperative to ensure that the measurement fluid is compatible with the materials used with the
pressure transmitter; similarly, the overload pressures and burst pressures must be adhered to
without fail (for these specifications, see the "Technical Data" and "Safety Information" of the EC
type examination certificate).
It is absolutely necessary to protect the internal measurement membrane of the pressure
transmitter against mechanical damage.
The data pertaining for the use in hazardous locations is to be heeded in any event.
Operation is only permitted if operational and process-related intensive electrostatic charges have
been eliminated.
When used in atmospheres containing combustible dusts, the pressure transmitter
has to be installed in such a way that it is protected from damage and knocks.
If the instrument is not handled correctly, or if the operating instructions and specifications are not
adhered to, damage to property and/or personal injury can result.
5.2
Intended use / foreseeable misuse
Claims for defects or liability, regardless of the legal foundation, do not apply with incorrect or
improper installation, commissioning, usage, handling, storage, maintenance, repair, use of
unsuitable components or other circumstances, which the manufacturer is not responsible for.
The manufacturer assumes no responsibility for determining the interfaces for installation in a
system or the installation, use or functionality of the product in this system.
5.3
Responsibility of the operator before start-up
In accordance with the EC Machinery Directive, the measuring system of a component is
considered to be a machine part for the installation into a system/machine. Moreover, the
conformity of the measuring system was investigated in respect of the EMC Directive.
It is therefore only permitted to start up the measuring system if it has been established that the
system/machine into which the measuring system is to be fitted, satisfies the provisions of the EC
Machinery Directive, the EC EMC Directive, the harmonised standards, European standards or the
corresponding national standards.
