- an opening command causes compression then release an opening spring, or a single spring, thus leading to the opening of contacts.
- the motor is activated automatically at the end of opening or closing of the contacts to reset the comes out in the corresponding position.
- a closing or opening command acts then, via trigger coils, on the attachment system for release the spring and cause the contacts to close or open.

- the CF and CO pushbuttons are open, the relays 3 and 4 are not supplied and the motor 1 is stopped.
- relay 3 is energized and closes the contact S1.
- Motor 1 is then supplied with voltage U1 until the contacts of the device are closed, which leads to the opening of the contact Ff1, the closing of the contact Fo1 and the interruption of the supply to the motor 1.
- an order of opening command produced by the CO push-button powers relay 4, closing the contact S2 and, if contact Fo1 is closed (device closed), supplying motor 1 up to that the Fo1 contact opens at the end of the device contacts opening stroke, the contact Ff1 then closing.
- the voltages U1, U2 and U3 are independent and depend on the voltages available in the station in which the device is mounted. Typically these voltages can vary from 24V to 220V, continuous or alternating. Of course relays 3 and 4, as well as the motor, should be chosen accordingly.
- the device is of the accumulation type in stride, the engine 1 acting on a spring which is compressed, then released immediately after the passage of a dead moin predetermined, when one of the CO control pushbuttons is actuated or CF.
- This device is also applicable in the case of direct control, the motor then acting directly on the contacts of the device.

It has second input terminals 9, to which the third supply voltage U3 is applied, via the CO push button. Third input terminals 10 are connected to a fourth supply voltage U4. First (11, 12) and second (13a, 14) output terminals are respectively connected to the terminals of the contacts S1 and S2.

- the motor control device is connected at terminals 15 and 16 and at the supply voltage U1. It has two output terminals 17 and 18 to which the motor 1 is connected.
- the closing command is provided by a full-wave rectifier 19a, a voltage regulator 20a, an optoelectronic coupler 21a and a circuit 22a for relay control, connected in series between input terminals 8 and relay 3.
- the opening control is carried out by analogous elements 19b, 20b, 21b and 22b, connected in series between input terminals 9 and relay 4.
- a signal inhibition I is applied to the relay control circuit 22a, via a optoelectronic coupler 21c connected to the voltage regulator 20b, when the push button CO is closed.
- Input terminals 10 apply fourth voltage supply U4 at the input of an auxiliary supply circuit 23, which provides a predetermined DC supply voltage U5, for example of the order of 47V, by relative to mass.
- the direct voltage U5 is in particular intended to supply the circuits arranged downstream of the optoelectronic links.
- the circuits 22a and 22b of relay control have respective power inputs 24a and 24b.
- the voltage U5 is not permanently applied to inputs 24a and 24b, the connection being made by through interface 6 ( Figure 7).

- a static switch T2 constituted in FIGS. 4 and 5 by a Darlington assembly, is connected in series with the associated relay, 3 or 4, between earth and the power supply input 24a or 24b, corresponding.
- the receiving part of the couplers 21a and 21b is connected between the corresponding power input, 24a or 24b and a control electrode for the associated static switch T2.
- the control circuits of relay 22a and 22b also make it possible to store the closing and opening orders supplied by CF and CO. For this, they each have an auxiliary contact, S3a or S3b normally open, respectively controlled by relays 3 and 4, and connected in parallel on the associated static switch T2.
- the inhibition signal I is supplied by the coupler 21c as soon as an opening order is given by the CO push button. Signal I is applied to the control electrode the static switch T2 of the control circuit 22a so as to short-circuit this control and blocking electrode T2.
- the relay 3 in the initial absence of a signal I, the relay 3 is actuated and closes the associated auxiliary contact S3a, short-circuiting the corresponding static switch T2, so that a subsequent inhibition signal is no longer taken into account until the end of the race closing and interrupting, by opening contact Ff2, of the supply of circuit 22a command for relay 3.
- the opening order was of the impulse type, then it has disappeared and the device remains closed.

- Engine 1 continues to be supplied, via relay 4 and contact S2, until the end of the stroke opening, the inhibition signal preventing any closing as long as the push button is closed. This prevents jolts in the event of fugitive opening orders as well that stopping an order in an intermediate position, while ensuring priority from an opening order to a closing order.

- the contact Ff1 is thus disposed between the terminals 12 and 16, and the contact Fo1 between terminals 14 and 16. Terminals 11, 13a and 15 are directly connected to each other.
- the limit switches Ff2 and Fo2 are also, preferably arranged in the interface 6, outside the control device 5 which can then be standard.

- This embodiment corresponds to that shown in the figure 1 where the contacts S1 and Ff1 are connected in series with the motor at the terminals of U1 and where contacts S2 and Fo1 are also connected in series with the motor at the terminals of U1.
- the standard control device therefore works with 4 voltages U1, U2, U3 and U4, which can all be different and arbitrary.
- the voltages U1 and U4 can be identical and supplied by the same power source.
- the control of the motor is realized via an additional relay 28 supplied by the voltage U5 supplied by the auxiliary supply circuit 23.
- the relay 28 is then connected between terminal 16 and earth, while terminals 15 and 27 are connected directly.
- Contacts S1 and Ff1 are then connected in series with relay 28 across the voltage U5 supplied by the auxiliary supply circuit. So does even contacts S2 and Fo1.
- the relay 28 controls a third contact S3, normally open, connected in series with the motor 1 across the supply voltage U1.
- control circuit 5 the interface 6 and the motor control circuit 7 are independent of the supply voltages.
- the motor must always be chosen according to the value of voltage U1.

- the contact S3 is connected upstream of the motor supply circuit 29.
- the circuit 29 is therefore not connected to the voltage U1 only when an opening or closing order activates relay 28.
- a second circuit auxiliary supply 30, connected to ground and voltage U5 via terminal 27, provides a DC supply voltage U7, adapted, for example 15V, to the components of the circuit 29.

- Conventionally, a voltage protection and assistance circuit the switching is connected in parallel on the transistor T4.
- a particular embodiment of the voltage measurement circuit 33 is shown in figure 13. It consists of an active filter connected between terminal 17 and earth.
- the filter active has a first-order RC filter that acts as an attenuator, followed by an active filter of the second order comprising an operational unity gain amplifier.
- Such a filter is conventional and will not be described in more detail.
- the power inputs 34 of circuits 32 and 33 are supplied by the voltage U7, by via a contact S4, normally open and whose closing is ordered by relay 28 at the same time as contact S3 is closed.
- the control circuit 32 provides logic control signals A so that the voltage U6 at the terminals of the motor 1 has a predetermined continuous value, for example 48V, and that the current in the motor remains below a predetermined value, for example example of the order of 8A.
- FIG. 14 illustrates a particular embodiment of the control circuit 32. It includes a pulse width modulation (PWM) circuit 35 providing signals A1 to a first shaping circuit 36, shown in more detail in the figure 16. The output of circuit 36 is connected by a pulse transformer 38 to the input of a second shaping circuit 37 supplying the transistor control signals A MOS T4. A reference voltage Uref1 is derived from the voltage applied to the input supply 34 of the control circuit 32.
- PWM pulse width modulation
- circuit 35 will be described in more detail using the waveforms of the signals U8, U9 and A1, shown respectively in Figures 15a, 15b and 15c.
- the signals A1 are binary logic signals, of predetermined frequency, by 15KHz example. As is conventional in pulse width modulation, the duty cycle of signals A1 is variable depending on the input voltage U8.
- the signal A commands the blocking of T4.
- the current remaining below the authorized limit if U8 becomes less than Uref1, then d takes a value d1 less than dO, and if U8 becomes greater than Urefl, then d takes a value d2 greater than dO.
- circuit 35 ignores the value of U8 and forces the signals A1 to zero, thus completely blocking T4 and interrupting the supply to motor 1. It would also possible to maintain a certain power supply to the motor then choosing a gear cyclic minimum predetermined, very low.
- the transistor T4 being in series with the motor 1 in a power circuit, where the current can reach 8A for example, the low power signals A1 are not adapted to the direct order from T4. In addition, T4 has no ground connection and therefore works floating source. Circuits 36 and 37, galvanically isolated by the transformer of pulses 38, fulfill this adaptation function.
- the circuit 36 includes two inverters 39 and 40.
- the inverter 39 receives the signals A1 as an input (FIG. 17a) and outputs A3 signals (Figure 17C) complementary to A1.

- the A4 output signals from the inverter 40 are illustrated in Figure 17d.
- A5 signals from output from circuit 36 consist of the difference between signals A3 and A4 and are of the shape shown in Figure 17e. These are fine, negative impulses after a brow A1 rising and positive after a A1 falling edge.

- FIG. 18 shows the internal diodes of the transistors T5 and T6.
- the drain of T5 is connected by a resistor R5 to the control electrode, or gate, of T4, while the drain of T6 is connected directly to the source of T4.
- the control signals A of T4 are applied between the gate and the source of T4.
- Two voltage dividers consisting of resistors R6 and R7 in series, respectively R8 and R9 in series, are connected in parallel on the secondary winding of the transformer 38.
- the point common to the resistors R6 and R7 is connected to the grid of T5 and the point common to R8 and R9 is connected to the grid of T6.
- the circuit start-up includes a transistor T7, type J-FET, connected between the drains of the transistors T5 and T6.
- the gate of T7 is connected to the anode of a diode D2 including the cathode is connected to the source of T5.
- the grid of T7 is, moreover, connected by a resistor R10, in parallel on a capacitor C1, to the drain of transistor T6.
- a D3 diode, of the type Transil is connected in parallel on T4, so as to limit the gate-source voltage of T4.
- FIGS. 19a to 19f on which the conduction of the transistors T5, T6, T7 and T4 is represented by a positive signal in Figures 19b, 19c, 19d and 19f respectively.
- the transformer 38 does not provide any pulse and the signals A6 (Figure 19a) are zero.
- the transistors T5 and T6 are both blocked and the transistor T7, which is of J-FET type, i.e. normally conductive in the absence of a command, is conductive ( Figure 19d).
- Signals A (figure 19e) are then at zero preventing a parasitic conduction of transistor T4.
- the capacitor C1 is recharged and T4 is blocks again. If the time between a negative pulse and a positive pulse is too large, capacitor C1 discharges completely and T7 becomes conductive again. The operation of the circuit 37 is then the same as in the conditions of starting.
- a latching accumulator control In a conventional latching accumulator control, the electric motor is used to automatically arm the spring (s), but does not intervene when a opening or closing order is sent.
- an opening order is applied directly to a Yo opening release coil, connected in series with CO across the voltage U3.
- Closing the CO opening push button applies the voltage U3 to the terminals of the coil Yo which releases the catch and causes the abrupt opening of the device contacts.
- a position contact of device contacts opening when the device is open, is connected in series with the Yo coil between terminals 9, so as to interrupt the supply of the Yo coil as soon as opening the device.

- the trip coil closing Yf intended to unlock the spring to close the device upon receipt of a closing order, is connected between one of the input terminals 8 and the terminal 14, while that the additional output terminal 13b is connected to the other input terminal 8.
- the contact S2 can take two positions.
- the contact S2 In its first position, shown in Figure 3 and corresponding to its open position in the description of the preceding figures, the contact S2 connects terminals 14 and 13b. In its second position it connects terminals 14 and 13a.
- relay 4 In its presence of an opening order, relay 4 is activated and the contact S2 interrupts the connection between terminals 14 and 13b, therefore the connection of the coil Yf to terminals 8 and pressing the CF push button has no effect.
- the device command 5 thus ensures the priority of an opening order over a closing order.
- the relay 3 is used for arming spring.
- the additional connection 42 (FIG. 4) is not cut. She short-circuits the receiving part of the optocoupler 21a and thus ensures the supply of the relay 3, independently of a closing order, when a voltage is applied to the power input 24a.
- the motor is connected between terminal 12 and one of the terminals 10, while the other terminal 10 is connected directly to terminal 11.
- the relay 3 is activated and contact S1, closed, connects terminals 11 and 12, applying voltage U4 to terminals of the motor.

- the motor supply circuit 29 can also be used to replace the motor with a standard motor.
- a standard control device 5 can be used regardless of the type of control desired.
- the main advantages of the circuit know the use of standard 3 and 4 relays, independent of the available voltages, and the priority of an opening order over a closing order, are found in all cases of figure, even if the trigger coils Yo and Yf of figure 20 remain adapted to input voltages.
