1.3.2 About emergency stops
The emergency stops
The purpose of the emergency stop function is to avert actual or impending
emergency situations arising from the behavior of persons or from an unexpected
hazardous event.
The emergency stop function is to be initiated by a single human action.
The emergency stop function is a complementary protective measure and shall
not be applied as a substitute for safeguarding measures and other functions or
safety functions.
The effect of an activated emergency stop device is sustained until the actuator
of the emergency stop device has been disengaged. This disengagement is only
possible by an intentional human action on the device where the command has
been initiated. The disengagement of the device shall not restart the machinery
but only permit restarting.
After actuation and before disengaging the emergency stop device, the machinery
shall be inspected in order to detect the reason for actuation.
