Safety Information
A4087-3.0 en/de
Appropriate Use
The module and the connected transducers may be used for measurement and
directly related control tasks only. Any other use is not appropriate.
To ensure safe operation, the module may only be used as specified in the
operating manual. It is also essential to follow the respective legal and safety
regulations for the application concerned during use. The same applies to the use
of accessories.
Each time, before starting up the modules, you must first run a project planning
and risk analysis that takes into account all the safety aspects of automation
technology. This particularly concerns personal and machine protection.
Additional safety precautions must be taken in plants where malfunctions could
cause major damage, loss of data or even personal injury. In the event of a fault,
these precautions establish safe operating conditions.
This can be done, for example, by mechanical interlocking, error signaling, limit
value switches, and such.
Safety Rules
A module must not be connected directly to a power supply network. The
maximum permissible supply voltage is:
CX23-R module
EX23-R module
MX modules
The supply connection, as well as the signal and sense leads, must be installed in
such a way that electromagnetic interference does not adversely affect device
functionality. (HBM recommendation: "Greenline shielding design," downloadable
from the Internet at http://www.hbm.com/greenline.)
Automation equipment and devices must be covered over in such a way that
adequate protection or locking against unintentional actuation is provided (such as
access checks, password protection, etc.).
When devices are working in a network, these networks must be designed in such
a way that malfunctions in individual nodes can be detected and shut down.
Safety precautions must be taken both in terms of hardware and software, so that
a line break or other interruptions to signal transmission, such as via the bus
interfaces, do not cause undefined states or loss of data in the automation device.
Conditions on Site
For all modules:
Observe the maximum permissible ambient temperatures given in the
l
specifications.
Minimize device exposure to direct sunlight in hot operating environments.
