METHOD FOR CHECKING THE FIRST CHECK RELAY AND SECOND CHECK RELAY OF THE CYCLICAL CODE CODING UNIT FOR RAILWAY INTERLOCKING SYSTEM EQUIPMENT AND THE CYCLICAL CODE CODING UNIT FOR IMPLEMENTING THE METHOD
Original language description
The method for checking the first check relay (X) and second check relay (Y) of the coding unit (C) according to this invention consists in that, the check circuit (CCC) of the cyclical codes periodically, after the repeating control time (TSC) elapses,looks for an intersection of the common state, when the cyclical codes (CC1, CC2, CC3, CC4), generated simultaneously in both the first branch (B1) and in the second branch (B2) all have zero voltage (UO) in the first branch (B1) and, at the same time, in the second branch (B2). Immediately after detecting this instant the cyclical code check circuit (CCC) initialises an impulse to the diagnostic circuit (DC) for the period of the testing time (TT), to interrupt, through the diagnostic switches (d1, d2), the driving circuits of the check relays (X, Y), whose armatures are released for a short period after the testing time (TT).
