The integrator of the final application is required to perform an assessment of the
hazards and risks (HRA).
Note
The integrator is responsible for the safety of the final application.
Safe access
The robot system shall be designed to allow safe access to all areas where
intervention is necessary during operation, adjustment, and maintenance.
Where it is necessary to perform tasks within the safeguarded space there shall
be safe and adequate access to the task locations.
Safety zones, which must be crossed before admittance, must be set up in front
of the robot's working space. Light beams or sensitive mats are suitable devices.
Turntables or the like should be used to keep the operator out of the robot's working
space.
A safety fence is recommended to ensure safeguarded space. Sufficient space
must be provided around the manipulator to protect those working with or on it
from hazards such as crushing.
The fence or enclosure must be dimensioned to withstand the force created if the
load being handled by the robot is dropped or released at maximum speed.
Determine the maximum speed from the maximum velocities of the robot axes and
from the position at which the robot is working in the work cell (see the section
Robot motion in the Product specification ).
Also consider the maximum possible impact caused by a breaking or malfunctioning
rotating tool or other device fitted to the robot.
Safe handling
Users shall not be exposed to hazards, including slipping, tripping, and falling
hazards.
It must be possible to safely turn off tools, such as milling cutters, etc. Make sure
that guards remain closed until the cutters stop rotating.
It should be possible to release parts by manual operation (valves).
Safe design
Emergency stop buttons must be positioned in easily accessible places so that
the robot can be stopped quickly. If any of the buttons do not stop all the robot
workcell motion, each emergency stop button must be marked, if more than one
is provided, to indicate its designated safety function.
Grippers/end effectors must be designed so that they do not drop work pieces/tools
in the event of a power failure or a disturbance to the controller.
Unauthorized modifications of the originally delivered robot are prohibited. Without
the consent of ABB, it is forbidden to attach additional parts through welding,
riveting, or drilling of new holes into the castings. The strength of the robot could
be affected.
