 werden muss. In Fig. 2 bedeutet A die den Motor speisende Anlassmaschine, e die gemeinsame Erregermaschine. Der Hauptsteuerhebel und die durch die beiden Steuerhebel geregelten Feldwiderstände sind in den nur schematischen Figuren nicht eingezeichnet. 



   Die vorstehend beschriebenen Einrichtungen, welche die Auslage des Hilfssteuerschalters in Abhängigkeit von der Drehzahl des Reversiermotors sichern, sind nur in Verbindung mit der mechanischen Verriegelung zwischen   Hilfs- und Hauptsteuerschalter   vollkommen, da ohne letztere, wie einleitend ausgeführt ist, unter Umständen bereits während des Auslegens des Hauptsteuerschalters eine solche Spannung und Tourenzahl am Motor erreicht werden kann, dal3 die hievon abhängige Verriegelung des Hilfssteuerhebels aufgehoben würde und infolgedessen ihr Ventil illusorisch werden könnte.

 must become. In Fig. 2, A denotes the starting machine feeding the engine, e denotes the common exciter. The main control lever and the field resistances controlled by the two control levers are not shown in the only schematic figures.



   The devices described above, which secure the display of the auxiliary control switch as a function of the speed of the reversing motor, are only complete in connection with the mechanical interlock between the auxiliary and main control switch, since without the latter, as stated in the introduction, under certain circumstances already during the interpretation of the Main control switch such a voltage and number of revolutions can be achieved on the engine that the dependent locking of the auxiliary control lever would be canceled and, as a result, your valve could become illusory.
