8.6.4. Relay breaker of the alarm system and indexes of turn


Fig. 8-34. Scheme of inclusion of indexes of turn and alarm system: 1 — block headlights with forward indexes of turn; 2 — side indexes of turn; 3 — the assembly block; 4 — the ignition relay; 5 — the ignition switch; 6 — the relay breaker of indexes of turn and the alarm system; 7 — the control lamp of indexes of turn located in a speedometer; 8 — back lamps with lamps of indexes of turn; 9 — the switch of the alarm system; 10 — the switch of indexes of turn in the three-lever switch; And — to the generator 30 plug; B — numbering of plugs in the switch of the alarm system; In — an order of conditional numbering of plugs in the relay breaker of indexes of turn and the alarm system

To the relay breaker 6 (fig. 8-34) it is intended for receiving a faltering light signal of indexes of turn both in the mode of the alarm system, and in the mode of the indication of turn, and also for control of serviceability of lamps of indexes of turn. If lamps are serviceable, then in the mode of the indication of turn it creates a blinking of a control lamp 7 with a usual frequency. If lamps are faulty (burn-out or break in a chain of lamps), then the relay breaker provides the doubled frequency of a blinking of a control lamp.
The relay breaker fastens under a guard of devices on a bolt, welded on an airinflow box wall. Faulty the relay breaker is not subject to repair and it should be replaced new.
Has to provide to the relay breaker a blinking of lamps of indexes of turn with a frequency of 90±30 cycles a minute at a rated load of 92 W, surrounding temperature from-20 to +50 °C and tension from 10,8 to 15 Century.
Till 1985 it was used the relay breaker 23.3747, collected on integrated chips. He created continuous burning of a control lamp in case of burn-out any of lamps of indexes of turn or break in a chain of its food.
Since 1985 the relay breaker 231.3747, made of discrete elements is installed.
Characteristics of both relays breakers identical. External difference consists only in absence at the relay breaker 231.3747 of the plug "5". Supply voltage moves only on the plug "1". Therefore the brown wire connecting earlier the relay breaker plug "5" to the plug "6" of the switch 9 (see fig. 8-34) is not necessary to the alarm system.
In 1995 the switch of the alarm system was a little changed. It liquidated conclusions "5" and "6", and also treason the scheme of connection of a control bulb in the switch.
