Universal Robots UR30 - Page 206

If the robot is installed in a robot application where hazards cannot be reasonably eliminated or
risks cannot be sufficiently reduced by use of the built-in safety-related functions (e.g.when
using a hazardous tool/end effector, or hazardous process), then safeguarding is required.
WARNING
Failure to conduct a application risk assessment can increase risks.
•
Always conduct an application risk assessment for foreseeable risks
and reasonably foreseeable misuse.
For collaborative applications, the risk assessment includes the
foreseeable risks due to collisions and to reasonably foreseeable
misuse.
The risk assessment shall address:
•
Severity of harm
•
Likelihood of occurrence
•
Possibility to avoid the hazardous situation
Potential
hazards
Universal Robots identifies the potential significant hazards listed below for consideration
by the integrator. Other significant hazards can be associated with a specific robot
application.
•
Penetration of skin by sharp edges and sharp points on tool/end effector or tool/end
effector connector.
•
Penetration of skin by sharp edges and sharp points on nearby obstacles.
•
Bruising due to contact.
•
Sprain or bone fracture due to impact.
•
Consequences due to loose bolts that hold the robot arm or tool/end effector.
•
Items falling out of, or flying from the tool/end effector, e.g. due to a poor grip or
power interruption.
•
Mistaken understanding of what is controlled by multiple emergency stop buttons.
•
Incorrect setting of the safety configuration parameters.
•
Incorrect settings due to unauthorized changes to the safety configuration
parameters.
