3 Fire-Extinguishing

Use a CARBON DIOXIDE extinguisher in the event of a fire in the robot (manip-
ulator or controller).

4 Definitions of Safety Functions

Emergency stop – IEC 204-1,10.7
A condition which overrides all other robot controls, removes drive power from robot
axis actuators, stops all moving parts and removes power from other dangerous func-
tions controlled by the robot.
Enabling device – ISO 11161, 3.4
A manually operated device which, when continuously activated in one position only,
allows hazardous functions but does not initiate them. In any other position, hazardous
functions can be stopped safely.
Safety stop – ISO 10218 (EN 775), 6.4.3
When a safety stop circuit is provided, each robot must be delivered with the necessary
connections for the safeguards and interlocks associated with this circuit. It is necessary
to reset the power to the machine actuators before any robot motion can be initiated.
However, if only the power to the machine actuators is reset, this should not suffice to
initiate any operation.
Reduced speed – ISO 10218 (EN 775), 3.2.17
A single, selectable velocity provided by the robot supplier which automatically
restricts the robot velocity to that specified in order to allow sufficient time for people
either to withdraw from the hazardous area or to stop the robot.
Interlock (for safeguarding) – ISO 10218 (EN 775), 3.2.8
A function that interconnects a guard(s) or a device(s) and the robot controller and/or
power system of the robot and its associated equipment.
Hold-to-run control – ISO 10218 (EN 775), 3.2.7
A control which only allows movements during its manual actuation and which causes
these movements to stop as soon as it is released.
