The first input of the element is NOT connected to the output of the control unit, the second input is connected to the first output of the first pulse distributor, and the second outputs of the second pulse distributor are connected to the inputs of the first OR elements. ,

The drawing shows the structural scheme of the proposed device.

The device consists of the second trigger 1, the second pulse generator 2, the control unit 3, the second pulse distributor 4, the first element OR 5, the first keys 6, the executive elements 7, the second element OR 8, controlled contact groups 9, the first trigger W, the first generator pulses 11, the control unit of the switch 12, the first pulse distributor 13, the switching, 14 cells, the switch 15, the monitored contacts 16, the first 17 and the second 18 reference blocks, the power source 19, the setpoint devices 20, the control unit 21, the element NOT 22, the fourth element OR 23, the element AND 24, the control unit KOHTpojieiyi of the contact 25, the third element OR 26 and the second key 27.

The device works as follows.

. When the device is turned on, the trigger / is set to the state enabling the generator 2 of the block 3.

The pulses from the output of the generator 2 are fed to the distributor 4, and then to the elements OR 5 and the keys in, which form the required time relationships between switching on and off three groups of elements 7 of the multiple coordinate connector in accordance with the principle of its operation.

The pulses from the output of the distributor 4 also arrive at the element OR 8, which generates pulses corresponding to the time intervals

control of the transition resistance of various contact-resistance contact groups 9 of the multiple coordinate connector, delayed with respect to the on and off elements of the respective groups of elements 7, as well as the leading edges | of the formed pulses sets the trigger 10 to a state that permits operation of the generator 11

block. The pulses from the generator // output go to the distributor, J3, which in turn opens and closes the cells 14 of the switch 15. And the frequency of operation of the generator // is much more

frequency generator 2.

The voltage drops created on the various contacts 16 and blocks 77 and 18 due to the flow of current. From source 19 through block 20, are alternately connected to

block 21, which compares them to the setpoint voltage. In the case of the EU, whether the voltage at a closed contact is less than the set voltage (or the voltage at an open contact is greater than the setting)

block 21 outputs a low potential that passes through the element NOT 22. At the same time, the element OR 23 generates pulses equal in duration to the total open time of the cells 14 connected to one of the controlled contact groups 9.

The signals from the output of the element OR 8 and.

23 go PA element And 24 block 25, and

then on the element OR 26. If it matches

These signals element 26 opens the key 27, | and the low potential from the output of block 22 does not change the states of the triggers 1 and 10.

If the voltage at a closed contact is greater than the voltage of the setpoint (or the voltage at the open contact is less than the setpoint), unit 21 outputs a high potential that passes through the HE element 22, the public key 27 c changes the state of three gages 1 W 10. Signal output

trigger / locks generator 2 and stops the test, and the signal from the output of trigger 10 locks generator 11 and stops the switch on the contact where the defect is fixed.

The device works in the same way when unlocking the next-to-last switching cell, which connects to block 21, the voltage from block 17, which is equal to the lower tolerance of the setpoint. When the last commutating cell is unlocked, a phase 22 inverter is turned on, the voltage from block 18, equal to the upper tolerance of the setpoint, passes to block 21, which provides a high potential. The HE element 22 produces a low potential that does not change the state of the flip-flops / and 10. In the event of a block 21 malfunction, a high potential appears at the output of block 22 at the moment of unlocking the last but one or last switching cell, and

tests are terminated.

When locking the last cell 14, the trigger W returns to the initial state and the generator 11 is locked. With the arrival of the next pulse of the element OR 8, the operation cycle of the device is repeated.

Thus, the introduction of triggers 10, elements OR, 23, AND 24, pulse distributor 4, generators 2, 11 and key 27 allows controlling multiple coordinate connectors by organizing synchronous operation of electromagnets 7 and switch 15, which expands the functionality of the device .
