The first wire of the first lighting section 11 is connected to the corresponding signal output of the control point 13 by means of the wire 17. The coil of the contactor 5 of point 2 is connected to terminal 18 for connecting the second working wire 11. The coil of the contact 4 of point 2 is connected to terminal 19 for connecting the first working wire 8 of the previous section of the lighting network. The coil of contactor 4 of point 3 is connected to the similar pin 19 of its item. The coil of contactor 5 of point 3 is connected to the phase B of the network;

- through the contact block 20 of the contactor 4, the block contact 21 of the contactor 5, pin 22, the relay 23;

- through contact 24 relays 25;

- through the contact pin 26 of the contactor 4.

Relay coil 25 is connected to terminal 10 to connect the first working wire of 8 point 3 through the following circuits:

-blocking contacts 27 and 28 contactors 5 and 4, respectively;

through the contact 29 of the relay 25. The relay coil 23 is connected to the output 10 of paragraph 3 through the contacts 30 and

31 / connected in parallel / relays 25 and 23 respectively.

The device works as follows.

An abrupt inclusion of the entire lighting.

The signal for switching on all the lights comes from the control panel 15 via communication line 14 to executive. point 13 and by means of wire 16 to the coil of contactor 4 of the main power point 1.

Turning on, the contactor 4 supplies the power supply voltage to the lighting network and, via the active working phase wire 8, goes to the intermediate power point 2. The contactor 4 is turned on, etc. to the final power point of the 3 cascade

The switching on of relay 25 does not occur, since the power supply circuit of the coil of relay 25 is interrupted by the auxiliary contact 27 of the de-energized contactor 5 of item 3.

When the contactor 4 of this item is turned on, the contactor 5 of the night lighting along the circuit is turned on: phase B ,, contact 22, relay 23, auxiliary contact 20 of the contactor 4, coil of the contactor 5.

the coil of the relay 25 is broken by the auxiliary contact 28 of the contactor 4, which is in the on state. Turning on the contactor 5 is blocked by its blocking contact 21 and delivers the supply voltage to the lighting network over the active working wire 11. This causes the contactor 5 of intermediate point 2 to be turned on, etc. to the main power point 1. In paragraph 1, wire 17 transmits information about the state of the switching on of the phase of night-time lighting to the executive point

13 through the communication line 14, to the control panel 15. The wire 16 provides information on the switching on of the evening lighting phase at the main power point 1.

Thus, the control panel 15 receives a signal about the mode of switching on the entire illumination.

In this mode, the contactors 4 and 5 are energized.

Night light mode .1

The mode is to de-energize the evening light phase. The signal for switching the network to night illumination comes from the control panel 15 via communication line 14 to the executive point 13. The wire 12 de-energizes, / the contactor 4 releases, which causes the de-energization of the phase working wire 8, which in turn causes the contactor 4 to be released 2, etc. to the final power point 3 Relay 25 does not turn on, as the phase operating wire 8 is de-energized. The contactor 5 of point 3 will not let go, because it is blocked by its block-contact 21 but the circuit:

- phase B, contact 22 of relay 23, auxiliary contact 21, a contactor coil 5.

The control panel 15 receives information about the night-light mode over the signal wire 17 through the execution point 13 via the communication line 14.

In this mode, the contactors 5 are energized.

Switching the network from night lighting mode to full lighting mode.

The mode consists in the fact that from the control panel 15 through the communication line

14, the executive point 13 receives a control signal which, by means of the wire 12, goes to the coil of the contactor 4 of the head post

power supply 1. By turning on the contactor; 4 applies voltage to the active phase working wire 8, and the entire evening lighting phase to the final power point is turned on.

8 moments of voltage on the wire 8 of paragraph 3 turns on the relay

25 on the chain:

- Phase A, wire 8, auxiliary contact 28 of a de-energized contactor 4, a block-on-contact 27 of a contactor 5, a coil 25. Due to the fact that the turn-on time of the relay 25 is much shorter than the response time of the contactor 4, the relay 25 is turned on ahead of the contactor 4 Switching on, relay

25 is blocked by its contact 29 on the circuit:

- Phase A, wire 8, pin 29, relay coil 25.

Turning on, the relay 25 with its contact 24 maintains the on state of the contactor 5 of point 3 along the circuit:

- Phase B of item 3, contact 24 of relay 25, contactor coil 5.

At the same time, the relay 25 with its contact 30 causes the switching on of the relay 23 along the circuit:

Phase B, point 3, main contact

9 is found in the on state of the contactor 5, contact 30 of the relay 25, the coil of the relay 23.

When activated, relay 23 is blocked by its contact 31 on the circuit:

- Phase B of item 3, main contact 9 in the on state of the contactor 5, contact 31 of the relay 23, relay coil 23.

Turning on, the relay 23 breaks the power supply circuit of the coil of contactor 5 of point 3, but does not change the switched on condition of contactor 5, (although the a-blocking circuit of contactor 5 will be opened), since the coil of the contactor will be connected to phase B by contact 24 of relay 25 located in On state, this lead time is determined by the response time of the relay 23 since the response time of the closing contacts 30 and 24 of the relay 25 is the same.

By that time, the contactor 4 of point 3 is turned on and with its blocking contact

26 will start to carry out two functions: it will pass through its contact part of the coil supply current, and in the off mode of the contactor 5 / under the condition

This release time of the relay and the contactor 4 is equal to each other (protects the contact 24 of the relay 25 from a large inductive current occurring at the moment of interruption of the inductive load supply circuit).

As a result, the phase working wire

The evening light and the phase operating wire 11 of the night light are under voltage, and the cascade is switched to the entire light mode.

In paragraph 1, wire 16 transmits information on the state of switching on the evening light phase to executive point 3 and on the SZ LINE 14 line to the control panel 15. Wire 17 provides information on the switched on phase state.

0 night lighting at the head station 1. The control panel 15 receives a signal on the switching-on mode of the entire lighting.

In this mode, are under current

5 contactors 4S5 relays 23 and 25.

Light off mode. It consists in de-energizing the evening light phase. From the control panel 15, the communication link 4 to the executive point 13 receives a signal to switch off the illumination. This causes the cable 12 to disappear. At the head point 1, the coil of the contactor 4 is de-energized, which causes the contactor to be released and the active phase working wire 8 of point 1 is de-energized, which causes the contactor to turn off 4 of point 2, etc., and the entire evening light phase

Q to the end point is de-energized. At the final power point 3, relay 25 and contactors 4 and 5 are disconnected.

Auxiliary contact 26 of the contactor 4 points 3, de-energizing the contactor 5 when

For its opening, is for the contactor 5 a chain of information signaling the opening of the block contact 20 of the contactor 4 / since the opening time of the closing block contacts 20 and

0 26 of contactor 4 is the same /, and the alarm is carried out when the self-blocking circuit of contactor 5 is interrupted by pin 22 of relay 23.

Relay 23 remains energized over a 5-point self-blocking circuit until the contactor 5 is released:

five

Being in the on state, the relay .23 with its contact 22 will maintain the break of the self-blocking circuit of the contactor 5g and control its on state until it is turned off. The disconnection of contactor 5 unambiguously means that the contactor 4 is in the released state, and the released state of the relay 25 (pin 24) is information about the de-energization of the evening illumination phase. Thus, the relay 23, via the release condition of the contactor 5 of point 3, monitors the state of the disconnection and the phase wire of the evening illumination. Having been switched off, the relay 23 restores the self-blocking circuit of the contactor 5 with its contact 22, after 5 the self-blocking circuit is interrupted by the block contacts 20 and 21 of the contactors 4 and 5, respectively. Turning off the contactor 5 causes the entire phase of the night illumination to turn off and in step 1, the wire 17 through the control point S3 via communication line 14 to the control panel 15 sends a signal that the night illumination phase is turned off. The signal wire 16 to the control unit 15 receives a signal that the phase of the evening illumination at head station 1 is turned off.

In this way, the operation mode of the outdoor lighting cascade network in the following sequential mode is provided:

- the inclusion of all lighting;

- the inclusion of night lighting;

- the inclusion of all the lighting from the state of the night lighting mode;

- turn off the lights. Mode off light from

the state of night lighting is achieved by briefly switching on the cascade network in the switching on mode of the entire lighting and then switching it off.
