In signal boxes in which the points are remotely controlled and monitored via lines leading to them it is common practice to provide common facilities, e.g. B. alarm clocks or lamps that are switched on when a switch is disturbed, for example when it is opened or when changing over the end position is not reached. In order to avoid that the error message also when changing the turnout appears, it is expediently switched on with a certain delay. This delay must be like this It can be significant that the malfunction message does not come even if several points are set one after the other be changed. The consequence of this is that the fault message will be issued even if an error occurs, z. B. in the event of a break in a monitoring line or when opening a switch, only appears after a long time.

In order to avoid these disadvantages, according to the invention, the fault alarms are one or more Delay relays are assigned, which are temporarily switched into Working position and switch off the malfunction signal during their reset time. This ■ Delay relays can also be used according to the invention to the control voltage to the Switch on turnouts so that it is switched off when a certain time after switching on the last switch this has not reached the end position. The control voltage is switched off expediently in that the circuit of the control voltage switch of the switches is interrupted. According to the invention, the delay relays can either be activated individually by activating the switches a turnout group key or a route indicator Setting of the turnouts can be switched on by pressing a route key. If the turnouts are set according to the route to reduce the inrush current switched on one after the other, the delay relays can also be used each time a changeover process is initiated through. the switch temporarily on; be switched. ;

It is according to the invention. It is advisable to use two delay relays, one of which is switched on by pressing a button or by closing a contact assigned to the switch and the other is switched off at the same time. The fault indicator is switched off and the control voltage is only switched on as long as both delay relays are in their working position. This ensures that the alarm is also switched on and the control voltage is also switched off if a key gets stuck or the contact assigned to the switch does not open again.

the delay relay is 'expediently an auxiliary' relay used.

Instead of the two. Delay relay you can also use a single delay relay, the is switched on alternately to two capacitors', one of which, for example, when pressed Button charged and when the button is released via the Relay winding is discharged and thereby the dropout delay of the relay while the second capacitor is reversed.

The activation of the fault indicator can be done by a common test relay can be controlled, which is brought into working position in a known manner, when a switch is disturbed. According to the invention, it is then also possible to connect the control voltage make it dependent on the test relay being in the working position. You can also use the Circuit of the fault indicator. Contacts of the test relay or arrange the delay relay according to the invention in such a way that the fault alarm is only switched off when all relays are in the working position or all relays are in the rest position. After another. Feature of the invention, it is advantageous to the malfunction indicator through the contacts of the To short-circuit the relay so that it responds even if a contact does not close. Used as a malfunction indicator If an alarm clock is used, you can also use an interrupt contact instead of the alarm clock short circuit. Through all of these measures it is achieved that disturbances such as getting stuck a Relays and the like make themselves noticeable to the operation or at least switch on the malfunction indicator. the

Two possible relay relays are switched on in the drawings. Exemplary embodiments of the invention are illustrated with the contact P2. 5 of the contacts P2, WU 2, FIl and F22

On the right this circuit is constantly excited in a simplified way, so that the alarm clock form the monitoring circuit of the switch no longer sounds.

Relays P, Vl and V2 , the alarm clock contact Wl is again short-circuited via the contacts P 2, WU 2, FIl and F22 (all in the position shown).

However, if the switch does not reach the end position, the drive contact A - does not close, and the monitor Ü cannot pick up, so that the relay P remains switched on. Then, after its delay time has elapsed, relay V2 drops out if relay H is switched off by contact; i? A-3 and. his contact St. has returned to the position shown. However, if the relay H remains energized, the relay V1 drops out after the delay time has elapsed. In both cases, by opening the contacts F14 or F24, the control voltage keeper S is switched off and the short circuit of the alarm clock contact W1 is canceled by means of the contacts F22 or F12, so that the alarm clock sounds and indicates the fault.

In the circuit example of FIG. 2, the circuits that belong to the individual switch are the same as in FIG. Also, the circuits of the joint device corresponding to those in FIG. 1, except that the contacts of the relay V2 omitted or is replaced, the contact F21 (Fig. 1) by a contact Cl5 the relay Vl (Fig. 2).

The sequence of the switching functions is initially the same as previously described, for example the relay R is switched on by pressing the WT and GT buttons and the relay Ü is switched off by the contact Ra2 , which switches on the relay P by closing the contact Ü 2. The relay H is switched on with the contact Ra 3. Closing the contact P 3 in FIG. 2 initially has no effect; however, if the relay H responds, the charged capacitor Ko 1 is connected to the relay Vl via the contacts H1 and P3 , so that it responds. At the same time, the capacitor Ko2 is connected to voltage through the contact H 2 and is charged. -

Via the contact VlA the control voltage keeper vS "is switched on, whereby the switch changeover is initiated. When the buttons GT and WT are released, the contacts RaI to Ra3 are reset by the relay R , whereby the relay H is switched off again with the contact Ra3 If the relay H remains energized, the relay Vl drops out after the delay time determined by the capacitor Ko 1 has elapsed, and the short-circuit circuit for the alarm clock contact Wl is interrupted by the opening contact ΡΊ2. If the relay H works properly, but reaches the If the end position does not change (whereby the relay P gets stuck), the relay Vl initially remains energized by switching on the capacitor Ko2 (via the contact H2) and keeps its contact F15 open; the relay Vl then drops after the second has expired Delay time, the contact F12 opens and removes the short circuit for the alarm clock contact Wl . is switched off by contact F14 when relay Vl drops out.

The contact R1 is used to change the turnout when it is included in a route and is not changed with the GT and WT buttons. In the position shown for the contact, it is only possible to switch to the minus position via line F -; If, however, the switch is switched to the minus position mod the contact R 1 is switched accordingly, the switch can only be switched to the plus position via the F + line. The further operation of the circuit in this case is the same as when changing the switch using the GT and WT buttons. .
