Safety instructions
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 modules 10 V
DC
... 30 V
DC
EX23-R module 10 V
DC
... 36 V
DC
MX modules 10 V
DC
... 30 V
DC
UPX modules (1-UPX001-2 or 1-UPX002-2) 10 V
DC
... 30 V
DC
CX22B(-R) modules 10 V
DC
... 30 V
DC
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 www.hbm.com.)
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.
