-  * Start button (green): This button is active in safety level ''slSystemReady''. Pressing it will fire an ''doAutoMoving'' event and the robot will go into safety level ''slAutoMoving''.

If pressed there, it will fire ''doControlStart'' which causes the robot to go into safety level ''slControlStarting'' from where the main sequence will restart.
-  * Stop button (blue): Press while being in auto moving state or in mouse moving state. It will fire an ''seStopMoving'' event which causes the safety system to level ''slSystemReady''.
-  * Stop button: Press three times while in safety level ''slSystemReady'' and the application will will park the tool center point and terminate subsequently.
+There are two critical outputs: the red and green LED lights. The red one is switched on when in emergency level, while the green one is switched on when the button has to be pressed: after an emergency to restart the robot and when in ''systemReady'', to start the automatic sequence.
