The invention relates to automatic control systems, can be used to control the repro-BepcuBHbiM mechanism, having several fixed positions, and is an improvement of the known device according to the basic author. St. No. 1158972,

The purpose of the invention is to increase the reliability of the device.

The drawing shows the electrical circuit of the device.

The device contains bus 1 power supply AC, n control closing buttons 2, n closing contacts 3 position sensors, n-1 diodes 4, power supply diodes 5 of relay 6 and 7 circuits, disconnecting contacts 8 and 9 closing contacts 10 and 11 respectively of relay 6 and 7 reverse, control windings 12 and 13, closing contacts 14 and 15, respectively, control windings 12 and 13, source

16 power windings 12 and 13 of the control and additional make contacts

17 and 18 reverse relay. The closing buttons 2 controls

they are connected to one busbar with the alternating current supply bus 1, and the other to one of the reed circuit terminals of the 3 position sensors,

Some of the winding pins of relays 6 and 7 of the reverse are connected to another bus 1 of the AC power, and the second leads, one through diode 5 in conductive voltage, and the other through another diode 5 in non-conductive voltage, connected to the combined second ends of the contacts 3 sensors 3 position.

The first terminals of the contactors of the 3 position sensors of each previous control button 2 are connected to each subsequent one via the diode 4. The diodes 4 form a sequential chain of a uniform conduction direction. The windings 12 and 13 control one output connected to the bus power supply source 16 of the control windings, and the other output connected in series closing 10 and 11 and disconnecting 8 and 9 contacts of one of the relay 6 and 7 of the reverse are connected to another bus power supply 1 control windings, the spreading contacts 8 and 9 of both relab 6 and 7 reverse are connected in parallel, and the closing contacts 11 and 15 of each

The control windings shunt the closing contacts 10 and 11 of the reverse relay in the circuit of the other control winding.

Between the disconnecting contacts 8 and 9 of the relay 6 and 7 of the reverse and another thickness of the power supply source 16, additional closing contacts 17 and 1B of the reverse relay are connected in parallel.

The device works as follows.

In the initial state, one of the position sensors, for example the second one, is closed as a result, the second contact 3 corresponding to it is also closed.

AC voltage from busbar 1, coming through the second control button 2, second closed contact 3 and diodes 5, is applied to both relays 6 and 7, in this case, contacts 17 and 18 are closed, and contacts 8 and 9 are open, and the power to the windings 12 and 13 from source 16 is not implemented. When you press any of the buttons 2, for example the fourth, the second button 2 is opened. As a result, the alternating voltage through the fourth closed button 2j diodes 4. and 5 is supplied to the reverse relay 7, while the reverse relay 6 is de-energized.

Contacts 10 and 17 are opened, and contact 9 is closed, and the voltage from the power supply 16 of the control windings is supplied to the control winding 13.

The reverse mechanism starts moving from the position corresponding to the closed state of the closing contacts 3 of the second position sensor to the fourth position sensor. The voltage from the busbars 1 of the AC power begins to flow to another reverse relay 6, and the opening contacts 8 and 9 open, the mechanism stops. When de-energized from busbar 1, the crimping contacts 17 and 18 are opened, breaking the supply circuit of the control windings from source 16,

Claims (1)

The device can be designed for any number of locking positions of the mechanism. Work, the device is similar when choosing other provisions, the claims A device for remote control of the reversing mechanism according to the ed. Eve, 1158972, differ-. 313832894 This is due to the fact that, in order to be parallel in parallel and connected between the reliability of the device, the closing contacts of the reverse relay and the power supply bus of the windings are introduced by the break contacts of the reverse relay reverse relay connected between co, control.
