SAFETY | 2.3 Residual hazards
2.3 Residual hazards
When carrying out a risk assessment of a machine in accordance with the EC Machinery Directive, the machine
manufacturer must consider the following residual risks which originate at the components of the controller and the
drive:
• Unintentional movements of driven machine components during commissioning, operation, maintenance, and
repairs caused by, for example:
Hardware malfunctions and/or software errors in the sensors, controllers, actuators, and connection techno-
logy
Response times of the controller and drive
Operating and/or ambient conditions which are 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
• Extreme temperatures as well as emissions of light, noise, particles, or gases caused by, for example:
Component malfunctions
Software errors
Operating and/or ambient conditions which are not within the scope of the specification
External influences / damage
• Hazardous shock voltages caused by, for example:
Component malfunctions
Influence of electrostatic charges
Induction of voltages in moving motors
Operating and/or ambient conditions which are not within the scope of the specification
Condensation/conductive contamination
External influences / damage
• Electrical, magnetic and electromagnetic fields generated in operation that can pose a danger to persons with a
pacemaker, implants or metal replacements, etc. if they are too close
• Release of environmental pollutants or emissions as a result of improper operation of the system and/or improper
disposal of components
For more information about residual risks of the components in the controller, refer to the relevant chapters in
this document.
