but in the power supply circuit of the address relay contacts and storey relay contacts. In the power supply circuits of relays 27 and 26, the contacts 29 and 30 storey switches are turned on; Relay 28 is shunted by a diode 31. The device operates as follows.

The cabin is on the first (odd) floor. Relay 24 is turned on. Contacts 24.1, 24.4, 24.6, 24.7 are closed and contacts 24.2, 24.3, 24.5, 24.8 are open. The rest of the relays are disconnected, their closing contacts are open, and the opening contacts are closed. Motion orders, for example, to the third floor, are submitted by pressing the push-button switch 12. Relay 4 is turned on, contacts 28.1, 4.3, 19.6, 29 and 26.1 receive power to relay 27, its contacts 27.2 and 27.3 are closed and open contact 27.1

Turning on the relay 27 leads to the turning on of the contactor of turning on the electric: motor Up and closing its contacts 16, turning on the relay B and opening its contact 8.1. After releasing the push-button switch 11, relay 4 is turned on via pins 16 and 4. 1.

Via contacts 27.2, 27.3, -22.2, 24.1 and 24.4, the relay 25 is turned on. Contacts 25.3 and 25.2 are closed, contacts 25.1 and 25.4 are opened.

When the cabin leaves the zone of interaction of the sensor with the shunt of the first floor, contacts 22.2 and 22.3 open, contacts 22.1 close.

Via contacts 22.2, 27.3, 22.1, 25.3 and 25.2, it is powered to turn off the relay 24. Contacts 24., 1, 24.4, 24.6 open, and contacts 24.2 close. 24.3, 24.5, 24.8.

Upon the arrival of the cabin to the second floor, as a result of the interaction of the sensor with the shunt of the second floor, contacts 22.2 and 22.3 are closed, contacts 22.1 are opened.

Through contacts 27.2, 27.3 ,. 22.2, 24.5, 19.1 and the third floor relay 19 turn on the second floor relay 18, contacts 18.1, 18.2, 18.3 close and contacts 18.4 open.

Via contacts 27.2, 27.3, 22.2, 55, 24.3 and 24.2, it receives power to turn off the relay 25 inter-zone zones, close contacts 25.1 and 25.4, and open contacts 25.2 and 25.3.

After the departure of the cabin from the second floor, the next switching of the contacts of the relay 22 occurs - the closure of the contacts 22.1 and the opening of the contacts 22.2 and 22.3. At the same time, contacts 27.2, 27.3, 22.1, 25.1 and 25.4 receive power to turn on the relay 24, the contacts 24.1, 24.4, 24.6, 24.7 are closed and the contacts 24.2, 24.3, 24.5, 24.8 are opened.

When the cabin arrives on the third floor, contacts 22.2 and 22.3 re-close, contacts 22.1 open. With

This, through contacts 27.2, 27.3, 22.2, of control by excluding self-starting and eliminating failures in the elevator during passenger erroneous actions, the cabin position detecting unit is equipped with a relay for passing the floor and interfloor zones, the first of which is connected to the power source via circuits , one of which consists of relay contacts connected in series

25 upward motions, a relay of se- lection pulses, a breaker contact of the relay passing through the interfloor zones, and a friend of the series-connected closing contacts of the motion relay upwards

2Q relays of selection pulses and a closing contact of the relay of interfloor zones, and a relay of interfloor zones connected to a power source through series-connected closing contacts of a motion relay Up, one of the disconnecting contacts of the relay of selection pulses and through one of the closing and disconnecting contacts of a floor relay. Other zones of the closing and opening | Tokling contacts of which are included. In the power supply circuit of the floor relays, made with single-winding. At that, 3 power supply circuits of each address relay include a pair Permanently connected make contacts of motor turn-on contactors up and down, and the directional detection unit is equipped with a relay arriving at a predetermined floor connected to a power source through another disconnecting contact of the pulse selection relay, third contacts of the relay for passing the floor zones, the contacts of the floor relay and the address relay, the break contact of the relay arriving at a given floor is included in the power supply circuit of the up and down motion relays.

24.6, 18.1 and 20.1. The relay 19 is turned on, contacts 19.2, 19.3 and 19.5 are closed and contacts 19.1, 19.4 and 19.6 are opened. Upon arrival on the third floor by contact 19.6 of the relay 19, the coil of the upward direction relay 27 is turned off. At the same time, contacts 27.2 and 27.3 are opened and contacts 27.1 are closed, the engine is switched off and the cab is stopped. third floor.

The operation of the circuit during the downward movement of the cabin is carried out through the contacts 26.2 and 26.3 of the downward direction relay which is switched on in this case. Contacts 26.2 and 26.3 switch the polarity of the power supply to the windings of the floor selection relays to the opposite polarity that occurred when moving. In this connection, with the passage of shunts, sequential shutdown of storey selection relays occurs,. previously included with the movement of the cab up. Similar to the upward movement, when the cabin moves down towards the odd floor, the relay 24 is turned on, and towards the even floor, this relay switches off. Relay 25, when moving down, turns on when the cabin leaves the even floor and turns off when leaving the odd floor.
