In the automatic operation becomes after clearing of the two - hand circuit Ø the cover hood lowered Ø the interlock closes and fixes the armature Ø the filling heading to the valve opening and presses the conical nipple in slightly Ø the fire extinguisher valve is opened Ø the helium filling cycle is started and terminated after a preset time Ø the nitrogen filling cycle is afterwards started and terminated after to achieve the adjustable current and the required filling pressure Ø the fire extinguisher valve is closed thereafter Ø the pressure conducting line system is relieved after acknowledgement that the system is pressure-free, Ø it becomes the filling heading back driven Ø the interlock opened Ø the cover hood opens
