 Die in der Figur dargestellte Anordnung ist aber auch zur Korrektur zu kurzer Erre- gungen des Stromstossempfangsrelais J, welche zur sicheren Wählereinstellung nicht aus- reichen würden, geeignet. Wie oben beschrieben, wird nämlich beim Ansprechen des Relais Q die Wicklung   III   des   Stromstossernpfangsrelais   J kurzgeschlossen, so dass der Abfall dieses
Relais leicht verzögert ist. Das Relais Q wird also über den Kontakt i noch etwas länger erregt gehalten, als das Stromstossempfangsrelais J   angesprochen hat. Ausserdem wird   das
Relais Q nach dem Abfall des Relais J bis zum Ansprechen des Relais 0 weiter erregt gehalten.

   Durch diese Einrichtung kann also auch bei Aufnahme zu kurzer   Stromstoss eire   für die Wählereinstellung genügend lange Stromschliessung am Kontakt q 3 erreicht werden.

 EMI2.1
 
Contact q 2 opens the circuit of relay 0 .. at contact q 1, opens the short circuit across winding 111 of relay J and interrupts the surge circuit for the downstream voters at contact q 3. If, in the meantime, the power surge receiving relay J has already been excited by a new current surge, the relay can only respond again after relay 0 has dropped out. With this device, a certain pause is switched on between the current closures at contact 3.

   Depending on the design of the relays 0 and Q in
 EMI2.2
 The arrangement shown in the figure is, however, also suitable for correcting too short excitations of the impulse receiving relay J, which would not be sufficient for a reliable selector setting. As described above, when the relay Q responds, the winding III of the Stromstossernpfangsrelais J is short-circuited, so that the drop of this
Relay is slightly delayed. The relay Q is kept energized via the contact i for a little longer than the surge receiving relay J has responded. In addition, it will
Relay Q kept energized after relay J has dropped out until relay 0 responds.

   With this device, a sufficiently long current closure at contact q 3 can be achieved even if the current surge is too short for the selector setting.

 assigned. which extend excessively short pauses between the individual current openings or current closing tongues of the current surges to be passed on.
