Consider the counter operation in the reverse counting mode. In this case, in the initial position, the relays 23 and the relay 10 are activated, the closing contacts 10.3 of which have prepared the switching circuit of the relay 9.

When the first input pulse arrives, relays 22 and 9 simultaneously operate. Relay 9 is triggered by a circuit. - input counting bus, diode 29, closing contacts 23.2 of relay 23, closing contacts 10.3, winding relay 9, bus 25, and through its shorting 5 sh; no contacts. 9.2 in the circuit 26 is self-blocking, the closing contacts 9.3 are prepared.
