Residual Risks
The control and drive components of an Industrial Shields PLC are approved for
industrial and commercial use in industrial line supplies. Their use in public line
supplies requires a different configuration and/or additional measures. These
components may only be operated in closed housings or in higher-level control
cabinets with protective covers that are closed, and when all of the protective devices
are used. These components may only be handled by qualified and trained technical
personnel who are knowledgeable and observe all of the safety information and
instructions on the components and in the associated technical user documentation.
When carrying out a risk assessment of a machine in accordance with the EU
Machinery Directive, the machine manufacturer must consider the following residual
risks associated with the control and drive components of a PDS.
1. Unintentional movements of driven machine components during commissioning,
operation, maintenance, and repairs caused by, for example: − Hardware defects
and/or software errors in the sensors, controllers, actuators, and connection technology
−Response times of the controller and drive − Operating and/or ambient conditions not
within the scope of the specification − Condensation / conductive contamination −
Parameterization, programming, cabling, and installation errors − Use of radio devices /
cellular phones in the immediate vicinity of the controller − External influences /
damage.
2. Exceptional temperatures as well as emissions of noise, particles, or gas caused by,
for example: − Component malfunctions − Software errors − Operating and/or
ambient conditions not within the scope of the specification − External
influences / damage.
3. Hazardous shock voltages caused by, for example: − Component malfunctions −
Influence of electrostatic charging − Induction of voltages in moving motors − Operating
and/or ambient conditions not within the scope of the specification − Condensation /
conductive contamination − External influences / damage
4. Electrical, magnetic and electromagnetic fields generated in operation that can pose
a risk to people with a pacemaker, implants or metal replacement joints, etc. if they are
too close.
5. Release of environmental pollutants or emissions because of improper operation of
the system and/or failure to dispose of components safely and correctly.
