3. Quelle (Reservebetrieb):

Im Normalbetrieb muss der Kugelhahn 

V2

 geschlossen sein. 

Bei Ausfall der Flaschenbatterieseite (2. Fehlerfall) erfolgt 
eine manuelle Zuschaltung der 3. Quelle durch Öffnen des 
Kugelhahnes 

V2

.

3rd source (reserve supply):

Ball valve 

V2

 must be closed in normal operation.  

The 3rd source is connected manually by opening ball valve 

V2

 if the cylinder manifold fails (2nd fault case).
