Operation and maintenance
For operation and maintenance, a person is considered competent when he/she has
the expertise and experience in the relevant field and is sufficiently familiar with the
application of the protective device on the machine and has been instructed by the
machine operator in its operation.
2.6
Safe state
In the safe state, the accordingly configured safe output signal switching devices are in
the OFF state. The robot is and remains switched off.
If the output for the safety-rated monitored speed is set to LOW, the robot controller
must safely monitor the speed of movement.
The safe state is initiated in the following cases:
•
Protective field infringed
•
Emergency stop pushbutton actuated
•
Fields are not infringed in an expected sequence (sequence error, no safety func‐
tion)
•
Connection between the safety laser scanner and safety controller interrupted
•
Voltage supply of the safety laser scanner or the safety controller interrupted
•
Internal error on the safety laser scanner detected
•
Internal fault detected at the safety controller or one of its components
NOTE
When the safety system initiates the safe state, the machine manufacturer and user
must ensure that the safe switching outputs are evaluated appropriately and that the
hazardous state is rectified.
