S
Automation equipment and devices must be designed
such as to ensure adequate protection or locking
against inadvertent actuation (e.g. access control,
password protection, etc.).
S
For devices operating in networks, safety precautions
must be taken in terms of both hardware and
software, so that an open circuit or other interruptions
to signal transmission do not result in undefined
states or loss of data in the automation device.
S
Following work on settings or password-protected
activities, make sure that any controls that may be
connected remain in a safe condition until the
switching behavior of the device has been tested.
Additional safety precautions
Additional safety precautions to meet the requirements of
the relevant national and local accident prevention
regulations must be taken in plants where malfunctions
could cause major damage, loss of data or even personal
injury.
The scope of supply and performance of the device
covers only a small area of measurement technology.
Before starting up the device in a system, a project
planning and risk analysis must first be implemented,
taking into account all the safety aspects of
measurement and automation technology so that residual
risks are minimized. This particularly concerns personal
and machine protection. In the event of a fault, the
relevant precautions must establish safe operating
conditions.
