through the contact of relay 18 to the second bus of power supply unit 3.

The device works as follows.

The master oscillator 2 generates pulses of the required frequency. When both electrodes of the glitter 1 are intact, there is a zero signal at the output of trigger 4 and therefore a unit signal arrives at the input of the And 8 element invert 1 for the output of this trigger 4. This state of the trigger 4 is established by the initial setup unit 10 at the time of initial switching on the circuit. Each of the pulses of the master oscillator 2 passes through the element 6, triggering trigger 5. Pulses to start trigger 5 are passed only when there is a voltage 11 on the arrester 1. The fact of voltage is detected by the zener diode 15. Resistor 13 limits the current in the zener diode 16. Zener diode 16 creates an insensitivity zone equal to the minimum voltage at which the gaps can be triggered (200-500 V). In the event that the impulse of the master oscillator 2 triggers the discharge 1, a current flows through it, the voltage drop from which on the shunt 20 triggers the zero-body 19. The latter causes reset of the trigger 5. In this case, at the output of the trigger 5 short pulses that, after filtering in filter 17, produce a small output voltage that does not trigger the relay 18. Filter 17 also acts as a delay unit.

In that case, when the gap

I does not create a current in its circuit, the zero-body 19 does not trigger, the trigger 5 is not reset, a constant signal is generated at its output, which triggers the relay 18. The latter with its contact gives a pulse to the trigger 4. The latter is triggered, removes the signal from the element And 8 and gives i, to the element. And 7. The start-up pulses go through the element And 7 and the amplifier

I1 on the second control electrode of the arrester 1.

Prompt switching from one control channel of the bit 1 to another makes it possible to virtually eliminate the interruption in the process. This removes the main

The cause of the most possible damage to an igniter array is a failure of the engine (development of the resource and the drop in resistance of the igniter to zero).
