NIN 22, to which the movable | 21 contact 21 of the address setting device 14 "is connected

A device for automatically selecting the direction of movement of an object operates as follows.

The address setter sets the address for moving the object, and three cases may occur.

The object is, for example, above the sensor with make contacts 25,30,36. The switch is set to the same address, the moving contact 21 is set to a fixed contact 17. In this case, the positive potential of the circuit is contact 21, contact 17, contact 36 is fed to the first terminal of the coil of the coincidence relay 40. At the same time, the positive potential from the contact 17 through the diode 44 circuit, the contact 25 is fed to the first terminal of the winding of the first relay 12 "

The contact 62 of the relay 40 first opens, then the contact 60 of the first relay 12 closes and the positive potential does not flow to the executive winding 58. The command to move the object is not given.

The object is, for example, above the sensor with make contacts 25,30,36. The switch sets the address, the moving contact 21 is set to a fixed contact 15. In this case, the positive potential of the circuit is contact 21, contact 15, diodes 47 and 8, contact 30 goes to the first winding terminal of the second relay 13, its contact 61 closes and opening contact 62 of relay 40; a positive potential is passed to the executive winding 59. A command is given to move the object. The object is moving up to sensors with closing contacts 23 and 34. Positive potential from contact 15 through contact 34 is fed to the coil 40 of the coincidence relay.

At the same time, the positive potential from contact 15 through diode 42, contact 23 is fed to the winding 12 of the first relay. The contact 62 of the relay 40 coincides first, and then the contact 60 of the first relay 12 closes, the Contact 62 de-energizes the windings 59, and the contact 57 of the relay 40 coincides with a positive potential to the return windings 55, 56, which return double-winding relays

At the same time, the positive potential from contact 15 through diode 42, contact 23 is fed to the winding 12 of the first relay. The contact 62 of the relay 40 coincides first, and then the contact 60 of the first relay 12 closes, the Contact 62 de-energizes the windings 59, and the contact 57 of the relay 40 coincides with a positive potential to the return windings 55, 56, which return double-winding relays

in the initial state - it should be noted on the commands for movement.

The object is, for example, a supervisor with closing contacts 25,30,36. Set the address switch, the movable contact 21 is set to a fixed contact 19. In this case, the positive potential of the circuit contact 21, contact 19, diodes 46 5,4 contact 25 is fed to the first step of the winding of the first relay 12. Further operation of the circuit is similar.
