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 as a result of improper operation
of the system and/or failure to dispose of components safely and correctly.
