The device works as follows.

A single pulse generator 1 generates a pulse that triggers the device. This impulse goes to the generator 2 random command codes, as well as through the first input-output of the element OR 3 to the single input of the trigger 4, transferring its state that corresponds to the standby mode of the device. The voltage from the direct output of the trigger 4 is fed to the first input of the element And 5, to the second input of which is received; em pulse from the first output of the generator 12, simulating the receipt of orders for the preparation of the system (operators and OP). This pulse from the output of the element And 5 is fed to the zero input of the trigger 4, throws it

the input of the flip-flops 11 and 12, the transfer to the initial state, as well as on the first driver 14, to the output of which a long pulse is generated

40, corresponding to the duration of the readiness mode of the servicing device for stand-alone checks. The voltage from the output of the shaper acts on the first input of the element.

45 and 54, open it.

When a second pulse is received from the second generator output 2, corresponding to the command to conduct autonomous checks, it passes through

50 cops AND 54 and OR 55 at the input, the start of generators 16 and 17. If during the time when the servicing device is in the standby mode, autonomous checks do not receive commands

gg is conducted from generator 2, then the back of the pulse front of the former 14 is fed to the input of the differentiating element 15, the output of which is a pulse corresponding to

This impulse arrives at zero

the input of the flip-flops 11 and 12, their transfer to the initial state, as well as to the input of the first shaper 14, at the output of which a pulse with a duration corresponding to the duration of the readiness mode of the servicing device for stand-alone checks is formed. The voltage from the output of the shaper 14 acts on the first input element.

And 54, open it.

When a pulse arrives from the second output of generator 2, corresponding to the command for conducting autonomous checks, it passes through elements AND 54 and OR 55 to the start input of generators 16 and 17. If during the service time the device is in stand-by mode for independent checks, no command is received on their

conduction from generator 2, the back front pulse of driver 14 acts on the input of differentiating element 15, at the output of which a pulse appears corresponding to the command to conduct autonomous checks. This pulse from the output of differentiating element 15 goes to the first input of the element OR 55 and further to the input starting the generators 16 and 17. At the output of the generator 16, a pulse duration is generated, corresponding to the duration of the autonomous testing phase. At the moment of the end of this pulse on the differential. of the element 18, an impulse appears that acts on the first input of the element 21 and the direct input of the element 20j on the inverse input of which is 15

The voltage comes from the direct output of the trigger 19, which is transferred to state 1 in case of detection of poor quality autonomous checks, which is simulated by pulse generation through a random time interval at the output of the generator 17, which simulates the quality control of the autonomous checks, the output of which connected to a single input trigger 19 ,.

The generator 17 is triggered by a pulse from the output of the element OR 55. If during the autonomous checks

poor quality of them is detected. 1, from the direct output of the trigger 30, the voltage goes to the first input of the element AND 32, opening it, and to the inverse input of the element 31, closing it. At the end of the pulse at the outputs of the generator 27 and the differentiating element 29, a pulse appears through the second input-: the output of the element 32 comes to the second input of the element IGSh 24, after which the device returns to the complex testing mode, this pulse goes to zero trigger input 30, resetting it to its original state.

If during the formation of a pulse at the output of the generator 27 the generator 28 did not operate, i.e. preliminary preparation was qualitative, then the pulse from the output of the differentiating element 29, obtained as a result of differentiation of the back edge of the pulse from the generator 27 output, is fed to the input of the generator 28 stop, through the input-output of the And 31. element: generator start input 34, simulating quality control of the final preparation of the equipment for the maintenance of the quotation, and at the start-up input of the generator 33, on.

leading, then the voltage from the output of the trigger 19 locks the element 20 and enters its inverse input and opens the element 21 and enters its second input, then the pulse from the output of the differentiating element 18 passes through the element 21 to the second input. the elements OR 7 and 8, to the zero I input of the trigger 19, transfer the device back to the preparation mode of the auxiliary and main equipment. If, however, no defects were detected during the inspection, i.e. pulse generator 17. has not developed, and there is no potential at the direct output of flip-flop 19, then the pulse from the output of differentiating element 18 stops the generator .17j arriving at its stop input, and also, having passed through the element AND 20j enters the input of the second shaper 22, the output of which begins to generate a pulse whose duration imitates the duration of the equipment readiness mode for complex checks. This voltage is permissive for an element 23, -bench at its first input, the second input of which receives a pulse from the third generator output

From the output of the element AND 23 a pulse through the first input-output of the element OR 24 is fed to the input of the generator 25, at the output of which, after a time imitating the duration of complex checks, a pulse appears which through the first input-output of the element OR 26 is fed to the input of the generator start 28, which simulates its quality control with the maintenance of the demand and to the input of the generator 27, at the output of which a pulse is formed, the duration of which corresponds to the duration of the preliminary preparation of the servicing device for servicing yu for wok. If defects are detected during the preliminary preparation, which is simulated by the appearance of a pulse at a random time interval at the output of the generator 28, the output of which is connected to the single input of the trigger 30 by transferring it to cocv

the output of which forms an impulse whose duration imitates the duration of the final preparation of the system for servicing the vozok. If defects are found during the final preparation, which is simulated by the appearance of a pulse at a random interval. time at the output of the generator 34, the output of which is connected to a single input of the trigger 36, transferring it to state 1, from the direct output of the trigger 36, the voltage goes to the second input of the element 38, opening it, and to the inverse input of the element 37, closing him. At the end of the pulse at the output of the generator 33, an impulse appears at the output of the differentiating element 35, which through the first input-output element AND 38 enters the second input of the element OR 26, after which the device switches back to the preliminary preparation mode, the same impulse also arrives 25 whereupon AND 41 is decrypted. em at the zero input of the trigger 36, - re- At the first output of the generator 48; Expression: its water in the original position. . the impulse is that
