 EMI1.1 
 
 EMI1.2 
 



   Als Mittel hiezu dient ein Tastrelais, das den Motor durch   An- und Abschalten   vom Netz oder durch Zwischenschalten von Widerständen steuert und das in   der Abfallage sieh   selbst einschaltet, im 
 EMI1.3 
   vorrichtung.   
 EMI1.4 
 

 <Desc/Clms Page number 2> 

 
 EMI2.1 
 legt die Feineinstellvorrichtung. den Bremslüfter und das Tastrelais an Spannung. Dieses springt an und   schliesst   einen Stromkreis von dem linken unteren Kontakt des Zeitrelais   ZR   über die oberen Kontakte von TR, die linken Kontakte der Feineinstellvorrichtung FV zu der Spule des entsprechenden 
 EMI2.2 
 Strom und fährt an.

   In seiner angezogenen Lage verharrt nun das Tastrelais unter dem Einfluss einer   Dämpfung   eine kurze Zeit, fällt dann ab und schliesst in der Abfallage seinen eigenen Stromkreis wieder. so dass es sofort wieder anspringt. Es wiederholen sich also so lange, wie die Rolle der Feineinstellvorriehtung sich noch auf der Stellschiene befindet, die Stromstoss auf den Motor, so dass dieser mit   s'geringer   Geschwindigkeit den Aufzug in die Haltestelle einfährt. Sobald die Rollen in der gezeichneten Stellung angekommen sind, ist der Stromkreis für das   Ständerschütz   und das Tastrelais TR unterbrochen: der Aufzug wird also stillgesetzt. 



   An Stelle dieser   Zeitsteuerung   des Motors durch das Tastrelais kann auch ein   Spannungswächter   vorgesehen werden, der in Abhängigkeit von der Geschwindigkeit den Motor steuert. Durch das Abfallen des Zeitrelais   Z. ss würde   der   Stromkreis   des an den   Motorankeridemmen   liegenden   Spannungs-   wächters geschlossen werden, und dieser würde seinerseits   wiederum   den Stromkreis für ein Ständer- 
 EMI2.3 
 die Geschwindigkeit um einige Prozent erniedrigt, so spricht der   Spannungswäehter   erneut an. Die Wirkungsweise des Spannungswächters ist also   grundsätzlich   die gleiche wie die   des'fa5trelais TR.   



   Wie aus der Beschreibung hervorgeht, erfolgt die Einschaltung des Motors durch das Nachstelltastrelais bei abgeschalteter   Anlassvorrichtung   ; es bleiben also sämtliche   Anlasswiderstände   vorgeschaltet. 



  Die Anordnung ist in gleicherweise für Drehstrom wie für Gleichstrom verwendbar. 



   Es erweist sieh unter Umständen als nötig, die durch   das Tastrelais erreichbare Geschwindigkeit   zu begrenzen. Dies kann man dadurch erreichen, dass man mit dem Tastrelais einen Spannungswächter verwendet, welcher bei einer   gewissen   Geschwindigkeit das Motormoment durch Einschalten eines Widerstandes schwäche. 



   PATENT-ANSPRÜCHE : 
1. Aufzugstenerung, bei der zur selbsttätigen Feineinstellung der Antriebsmotor benutzt wird, dadurch gekennzeichnet, dass in Reihe mit einem Kontakt der Feineinstellvorrichtung (Bündigschalter) ein Tastrelais liegt, dessen Kontakt in der Abfallstellung den Stromkreis für dieses Tastrelais und in der Betriebsstellung den Stromkreis für den Motor   schliesst.

   The means for this is a push button relay that controls the motor by switching it on and off from the mains or by interposing resistors and which switches on itself in the waste position

   contraption.

 EMI2.1
 sets the fine adjustment device. the brake fan and the push button relay to voltage. This starts and closes a circuit from the lower left contact of the timing relay ZR via the upper contacts of TR, the left contacts of the fine adjustment device FV to the coil of the corresponding
 EMI2.2
 Electricity and starts.

   The push button relay remains in its attracted position for a short time under the influence of damping, then drops out and closes its own circuit again in the drop position. so that it starts again immediately. As long as the roller of the fine adjustment device is still on the adjusting rail, the current impulses on the motor are repeated, so that it drives the elevator into the stop at low speed. As soon as the rollers have reached the position shown, the circuit for the stator contactor and the touch relay TR is interrupted: the elevator is therefore stopped.



   Instead of this time control of the motor by the push button relay, a voltage monitor can be provided that controls the motor depending on the speed. If the timing relay Z.ss would drop out, the circuit of the voltage monitor connected to the motor armature terminals would be closed, and this in turn would in turn open the circuit for a stator
 EMI2.3
 If the speed is reduced by a few percent, the voltage monitor responds again. The function of the voltage monitor is basically the same as that of the'fa5trelais TR.



   As can be seen from the description, the motor is switched on by the readjusting pushbutton relay when the starting device is switched off; So all starting resistors remain connected upstream.



  The arrangement can be used in the same way for three-phase current as for direct current.



   It may prove necessary to limit the speed that can be achieved by the pushbutton relay. This can be achieved by using a voltage monitor with the push button relay, which at a certain speed weakens the motor torque by switching on a resistor.



   PATENT CLAIMS:
1. Elevator stiffening, in which the drive motor is used for automatic fine adjustment, characterized in that a touch relay is in series with a contact of the fine adjustment device (flush switch), the contact of which in the drop-out position the circuit for this touch relay and in the operating position the circuit for the Motor closes.
