DEVICE FOR CHECKING WIRING

摘要

ELECTRICAL INSTALLATION MONITORING DEVICE containing an indication unit, clock generator connected to clock inputs of the first single pulse generator and control pulse driver unit, four information inputs of which are connected to the corresponding keyboard outputs, address switches connected to information inputs of the address signal generator addresses, and the tires of the type of check — with information inputs of the first buffer register that control inputs The address signal generator, the address register and the first buffer register are connected respectively to the first, second and third outputs of the control pulse shaper unit, the fourth output connected to the first input of the first OR element of the interrupt shaping node, consisting of the first RS trigger, the second OR element and the first And connected by the output to the information input of the first single pulse generator and the second input of the OR element, the output of which is connected to the R input of the first trigger, 8 input connection The output of the second element OR, which is connected to the first input to the first output of the test result analysis node, consisting of a block of elements 2И-OR and the first comparison block, the output of which is connected to the first input of the block of elements 2И-OR, and the first input together with the information the inputs of the switch are connected to the input of the device, the second input of the first comparison unit is connected to you (L of the reference number generator, the control input connected with the output of the first buffer register, and the information input - with the output of address address signal generator, which is the output of the control address of the device, 1c with the address input of the switch and the first input of the second comparison unit, the second input of the address register connected to the DO output, and the output with the 00–00 first input of the first AND element, characterized in that In order to increase the reliability of the control results, a measuring node consisting of an amplifier unit, a comparator and a reference voltage block, a code converter, a test type generating unit consisting of the third and tvertogo element or shaper shift pulses, the shift register forming species and test the first block member and
