The register 6 consists of flip-flops 20, -20, the display unit 10 contains indicators, the block 11 elements addition modulo 2 contains two-input elements M2 22, -22g, block 9 display contains indicators 23, register 8 contains triggers 24-24k, register 7 consists of triggers 25 25 ,, block 13 elements AND contains elements AND NOT 26, - 26.

The device works as follows.

in a way. X

Operator after power on

The power supply by means of the switch 14 sets the triggers 20 of the registers 6 to 8 to their initial state, in which the indicators of all indication units (e.g., LEDs, glow lamps, elements on liquid crystals) are in the off (inactive) state. The operator then selects any point of the first monitored circuit and with probe 5 touches the indicator housings on the display units 3 and 10 (corresponding to the selected contact). In this case, the selected indicator lights turn on (turn on), as well as indicators that correspond to the contacts entering the controlled circuit in controllable 1 and in the reference 2 products; because

the indicators in each block are connected through chains of the monitored and reference products, respectively, and the probe 5 is under the zero potential set by the switch 15. After removing the probe 5 from selected housings, the display indicators of the monitored and reference circuits on blocks 3 and 10 are saved, since the on state of the indicators is maintained by the associated triggers of registers 6 and 7. When the enable signal is applied to the block 13 of the AND elements from the switch 16, the indication block 9 displays contact groups (for example, , Sockets) within which are present, erroneous compound, found by block 11 elements modulo 2 addition and grouped by the block 12, OR elements. On the basis of the indications of the display unit 9, the operator compares the indications of the pairs of indicators of the blocks 2 and 10, which represent the states of the equivalent contacts of the monitored and reference items. If both indicators in this pair are turned on, then the corresponding contact of the controlled product is mounted correctly. If a controlled circuit indicator is not included in such a pair, then in item 1 there is no corresponding, fragment of the circuit. If the reference circuit indicator is not included in this pair, then item 1 has an extra electrical link. The display unit 9 provides the search for errors, indicating the groups of contacts (connectors) in which there are errors. This saves the operator from having to look at all pairs of indicators.

The operator has the ability to simultaneously select several isolated circuits by sequentially touching them with the probe 5. For example, if the controlled circuit is broken into several fragments, then the operator can determine the number of these fragments in the indicated way. The display unit 9 also serves to register the fact of viewing and fixing all points of the circuit in this connector containing errors. To do this, after performing such an operation, the operator using the probe 5, setting the potential of the power source from the switch 15, turns off the corresponding indicator of the block 9, which indicates the presence of an error in this connector. Similarly, the operator turns off the indicators of blocks 3 and 10 corresponding to a specific circuit. Switching off (reset) of all indicators of blocks 2, 9 and 10 of the indication simultaneously is carried out using the switch 14, which acts on the triggers of registers 6 to 8 on the setup input. After analyzing the first circuit, proceed to the control of the next circuit. The starting points of the chains can be selected from the connection table or be indicated on the indicator panel using a stencil or marks. It is possible to make a complete detour of all points without using the table of compounds or indexes of the starting points of the chains. Product inspection can be combined with an error correction process. In this case, the device for controlling the installation is used for in-depth diagnosis of communications and step-by-step monitoring of operations for correcting the installation. The device allows you to select the controlled and reference circuits by briefly touching the indicator housings with a stylus, indicating groups of contacts (connectors) containing wiring errors, the ability to simultaneously display any number of circuits, the ability to control without reference to the connection table, i.e. not required by operator
