Description

Electrically controlled time machine

The invention relates to a time machine as used in lighting systems of houses as a so-called staircase automat is used to automatically turn off the switched on Light after a certain time.

The time machines previously provided in lighting systems often cause problems due to the electro-mechanical devices a strong unpleasant noise. In addition, they can only be regulated within relatively narrow limits. There are also time machines, which respond to warmth and at. which consequently the release button for a relatively long time, at least for about a second. Furthermore, the duration of the temporization depends on the surrounding temperature and the thermo-resistive element has a relatively limited one Lifetime on.

The purpose of the invention is to create a time machine, which does not have the disadvantages of conventional time machines listed above shows.

The invention is therefore an electrically controlled time machine with a main relay, in which the power supply through Pushing a button is turned on and with a temporizing system in which the power is fed through the whole relay is switched on, with the distinguishing features of the time machine consist in the fact that the main relay is a so-called step relay, which assumes two stable positions and that its contacts on the one hand the passage and interruption of the utility current and on the other hand the undervoltage setting control of the temporization system, the circuit of which has a capacitor connected in parallel at the outputs a branch with a gas lamp and the winding of a second Beiais is connected, which can switch on a line, through which the main relay is switched on.

Four embodiments of the electrically controlled time machine according to the invention are referred to below Described on the drawing, namely FIGS. 1 to 4 each show circuit diagrams for four different possibilities of execution.

BATH ORIGINAL 909833/0520

The electrically controlled time machine shown in Fig. 1 contains a main relay RP of a special type, in the present case a relay with a stuferureisem control pulse, its main contact SP 1 has two stable positions. Every time the coil of the relay is energized, the main contact RP 1 changes its Position, i.e. it closes when it was separated and it separates when it was closed. The is in rest position Contact normally separated.

The coil of the main relay can be of a suitable electrical Distribution network DI, which carries e.g. 110 V alternating current, can be supplied with electricity.

The relay controls the power supply to the utility circuit U and also the one for the temporization system. This closes you Capacitor C, to which a branch is connected in parallel, in which a gas lamp 1> and the winding of another Relaxe RX, which are used to interrupt the time machine should take care of.

For the sake of better understanding, the circuit diagram can be divided into four main parts:

1. the control circuit of the ⁿ auptrelais rpj

2. The charging circuit of the capacitor Cj

3. the discharge circuit of the capacitor C and 4 · the use current circuit TT.

909833/05 20

The charge circuit of capacitor C and the discharge circuit represent, so to speak, the complete circuit of the temporization system, which is denoted by 5

1. The control circuit of the main relay EP consists of a push button BP, which is arranged parallel to the auxiliary relay contact associated with a RX 1, wherein the whole pule in series with the ^above the main relay is connected in BP. The two ends A, B of the control circuit are each connected to the current-supplying connections F and G via lines 1 and 2.

If it is a time machine that is to be operated from several locations, the respective Control buttons must of course be connected in parallel

2. The charging circuit of the capacitor C consists of a resistor R1, which is located behind the capacitor C. The value this resistor regulates the charge intensity directly, the resistor R1 being variable in such a way that the regulation level has to be increased.

The capacitor C and the resistor R1 are connected in parallel to a resistor R2, which in turn is behind a

909833/0520

Potentiometer P and a ^ rectifier point S is located. A Interrupter T finally enables the charging circuit o to be switched off

The end E of this circuit (on the breaker side) is connected to the normal power connection F.

The other end of this circuit, which is out of line exists, is to the other pole of the power connection G through the main contact EP 1 of the main relay RP via lines 2 and 3 connected

The voltage difference can be adjusted with the potentiometer P. at the terminals of the resistor R2 regulate, thereby simultaneously the charging current flowing through resistor R1, is adjustable

3 * The discharge circuit has a parallel to capacitor C. Line 7, in which a lamp L (neon tube) and the coil of the auxiliary relay HX.

The capacitor can be discharged via a line 9 proceed, which includes a contact BP 3, which

parallel to the capacitor C. The contact dp j _f which makes up part of the "main relay" is a break contact which only closes when the coil of the main relay is energized.

4. The usage circuit U runs parallel to the charging circuit of the capacitor C. The connection 4 of the circuit U is with the pole Gr on the line 10, the contact BP 1 and the Line 2 connected, while the other pole 6 of the circuit U is directly connected to the terminal F.

The timer works as follows:

Is the time machine connected to an electrical distribution network and the interrupter T is switched on, all that is needed to operate the timer is a simple press of any even very short duration on the push button BP. This will make the Main relay coil HP current supplied. This is followed by the contact BP 1 des Helais, which was open and the ensures that, on the one hand, the user electricity circuit U under Voltage is set and on the other hand that the circuit 5 of the temporization system with the resistors and the Capacitor C is charged.

After the time for which the timer was set by setting the potentiometer P has elapsed, this is sufficient

Voltage at the connection points of the capacitor C in addition, in order to ensure the charging of the neon tube L, which then becomes conductive. This ensures the power supply to the auxiliary relay RX. The contact RX 1 of the heater then closes with short interruptions during the discharge of the neon tube. This ensures that the coil of the main relay RP is charged. The main contact RP 1 opens. The contact interrupts then simultaneously power to HutzungsStromkreis · U and the power to the circuit 5 of the Teaporisierungssystems.

At the same time the interrupter contact RP 3 of the main relay has closed and the short circuit of the capacitor ^{c has been} ensured in such a way that any reactive charge in the latter is eliminated.

In the mode of operation just described, a single press on the push button BP closes the power supply to the utility circuit, namely during the specified duration of the temporization of the time machine.

The duration of the temporization can be regulated as desired, namely with the potentiometer P. The one sitting in the circuit 5 Resistor R 2 can be an adjustable resistor, which means

90983 3/0520

set several gradations in the temporization. Other resistors can also be used in the power supply to adapt the system to the respective voltage of the power grid adapt.

It should be noted that if during operation of the Automatic timer the push button BP is pressed at any moment, as a result of which there is a premature power supply to the main relay HP, which causes an interruption of the usage circuit U before the temporization time has elapsed.

This gives you the opportunity to operate the push button to change the temporization duration as desired without the position of the slot machine and without having to touch it it becomes necessary to install an additional part, since the same button is used to interrupt the circuit as to activate it.

The electrically controlled time machine according to the invention has the advantage that it works safely and quietly and that its Wear is practically zero. This time machine can then be used in A system can be installed as an interrupter without any changes being made, since it is sufficient to have a

press the shutter release button a second time to release the To cause interruption of the usage circuit before the temporizing time determined by the timer has elapsed is · you sohon elapsed at the start of a second shift Time is turned off. It in no way comes from that Sequence of the following temporization to take effect

If you open the breaker T, you can neutralize the temporization system. In this case, a first ensures Pressure that takes place on the push button BP supplies power to the Coil of the Beiais BP and consequently the power supply to the utility circuit U until no second pressure on the aforementioned Push button takes place. When this second pressure is exerted, it causes the contact Bp 1 of the main relay to change from the closed position to the open position in such a way that thereby the power supply »u / the Mutzuagsstromkreis U from the distance can be controlled

In Fig. 3 is the circuit diagram of a third embodiment a Zeitautoaaten according to the invention shown, which is designed in such a way that the closure of the push button BP no interruption of the Utilization currents U could cause, as in the execution options according to the Sahalt plans of FIGS. 1 and 2.

For certain applications, especially when on a timer intended for installation in house lighting is, care must be taken that an opening of the power supply is avoided in the course of the operating sequence, namely when another user presses the pushbutton one more time.

The general layout of this third timing machine is similar to that of the previous one. So his strokes are roughly the same and the components that correspond to those in the first embodiment are provided with the same reference numerals in the drawing.

As above, the main relay is BP with a double contact with reversing Hp i / BP 2 equipped. The relay also has an auxiliary contact RP 4 which is closed in the rest position. This contact sits in line 8, which is also where the iJP push button is located.

909833/05 20

As soon as this contact is opened, it prevents the pressing of the push button from controlling the operation of the relay BF. Under these conditions, it is impossible to activate the BP cause and consequently also impossible to switch the power supply to the Hutzungstromkreis U by actuating the pressure » to stop button

The time machine is only triggered by means of the Temporization svetems. As soon as the timer is triggered, this ensures that the push button is pressed in normally its tripping again, because the auxiliary contact BP 4 is then closed · In this version, the breaker is T omitted, because it is then not necessary

In certain applications, e.g. where a timer is installed in a lighting system in a stairwell, it is advantageous to be able to operate the timer at will before it is triggered under the action of the temporization system the Xutzungsstromkreis is interrupted as ron the case for the schematic? ig. t would be.

4 shows the circuit diagram of a time machine which consists of the same elements as are found in the above time machine, but which is designed in such a way that the goal parts to be carried out in the following can be achieved. The circuit diagram can be compared with the circuit diagram of FIG. The main relay BP faces the main contact 1 a HP D _O ppelkontakt ^mi * reversal T2 up TJ. In the latter, the contact T2 is closed in the rest position, while the contact T) is closed after actuation of the relay. Both contacts have a common point H which is connected to the push button BP. The contact T3 is connected by a line 9a to the point D, which represents a common point for the resistor R1, the capacitor C and the discharge lamp L. The contact T 2 is connected to the winding of the main relay RP.

The peculiarity of this circuit diagram is based on the The fact that the endpoints A and B of the control circuit a

of the main relay ^ P are connected in the opposite way to how which is provided in the circuit diagram of FIG. That's how it is

Point A is connected to power connection G via line 2

and the point B to the power connection F via line 1. This

The timer works as follows Pressing the push button BP ensures the power supply

was closed. As a result, the relay works and is guaranteed on the one hand the closure of the main contact RP 1 and on the other hand the opening of the first auxiliary contact T2, whereupon the Closing of the second auxiliary contact T 3 follows.

It ensures that the main contact RP 1 closes at the same time the power supply to the use a power circuit U and the power supply to the circuit 5 of the temporization system. After a certain The voltage at the connections of the capacitor C is sufficient for the neon tube L to charge. The auxiliary relay HX speaks on and then the power is supplied to the coil of the main relay RP. This relay actuates and controls the opening of the main contact RP 1 and also the opening of the auxiliary contact Tj and thus also the closure of the auxiliary contact T2.

The power supply to the usage circuit and the power supply to the circuit of the temporization system are then interrupted. The various contacts of the relays are in the starting position, so that the time machine can meet again in ätigkeit ^x ·

However, if the pushbutton BP is pressed in during the operation of this automatic timer, no new one can be used Actuation of the main relay RP are caused, which lead to an interruption of the power supply to the HutzungsStromkreis

could. The ^ iIfekontakt T2 _t, which is located in line 1, is then open

The impressions dee Druokknopfes ensured as "flowing through the current in the line 9a _t since the contact assistance TJ was closed. This results in a bottom course of the capacitor C of the temporization system.

In the course of the present operating sequence, the already ticked-out time is certain — pen equals VuIl. The temporization thus goes τοη the moment aam, when the new actuation of the pushbutton BP stops. The current continues to run without interruption in the circuit of the ^ emporiaiertuigssy stems, since the main contact BP 1 has remained constantly closed.

Pressing the push button BP 1 cannot cause an instantaneous interruption of the maintenance circuit, what means an extremely important benefit.

Furthermore, the pressing of the push button in the course of the actuation in the time machine does not cause any Belais movement, as a result of which the quiet operation of this time machine is guaranteed
