The residual risk
When assessing his machine's risk in accordance with the EC Machinery Directive, the
machine manufacturer must take into account the following residual risks emanating from the
control and drive components:
1. Unintentional movements of driven machine components during commissioning,
2. Exceptional temperatures as well as emissions of light, noise, particles, or gas caused by,
3. Hazardous shock voltages caused by, for example:
4. Electrical, magnetic and electromagnetic fields generated in operation that can pose a
5. Release of environmental pollutants or emissions as a result of improper operation of the
188
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
– Parameterization, programming, cabling, and installation errors
– Use of radio devices / cellular phones in the immediate vicinity of the controller
– External influences / damage
for example:
– Component malfunctions
– Software errors
– Operating and/or ambient conditions not within the scope of the specification
– External influences / damage
– 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
risk to people with a pacemaker, implants or metal replacement joints, etc. if they are too
