Process for the realisation of an indefinite interruption of renumbering and application to a semi-automatic renumbering arrangement

摘要

circuit board with, inter alia, an output terminal (27) which,during the finite period (ts) of supply voltage (vs) to break is greater than a threshold value (t) and an input terminal (28) which interrupts the renumbering when ladivoltage (vs) to interruption is applied.the current voltage characteristic (31) of the input terminal (28) is such that the current is continuously for a voltage value between zero and the value of the threshold (t) giftborn, and is virtually non-existent for voltages in excess of the threshold value.according to the invention.this process is characterised in that it is between the output terminal (27) and the input terminal (28), a unidirectional conductor (32) whose meaning is the only way outto the input terminal.and we connect the input terminal (28) with means (33) for maintaining the voltage of the input terminal to a value greater than the threshold value (t) in the period after theover (t) interruption of the output terminal (27) is no longer issuing the voltage (vs) of the interruption.
