2.4.2.4. Automatically Recoverable Protective Stop
The door switch is an example of a basic protective stop device. When the door is
open, the robotic arm stops. See the figure below.
This configuration is only for applications where the operator is unable to close the
door from behind. Configurable I/O can be used to set the reset button outside the
door, as to reactivate the movement of the robotic arm. Another example of an
automatic recovery is the use of a safety pad or a safety laser scanner, see the figure
below.
2.4.2.5. Protective Stop with Reset Button
If you use a protective interface to interact with the light curtain, you need to reset
from outside the safety zone. The reset button must be a two-channel button. In the
example shown below, the I/O of the reset configuration is “CI0-CI1”.(the
corresponding configuration must also be done in xArmStudio)
