PURPOSE:To reduce the processed load of central control unit, by producing the delivery pulse control signal at the delivery pulse control signal generator and performing fine tuning through the timing determined independently of the central control unit. CONSTITUTION:The delivery pulse control signal generator (not shown) is connected to the delivery pulse control signal input terminal P, and the signal PCS alternately repeating the signal state 1 and non-signal state O with a given period in response to the delivery pulse is fed, and the signal PCS specifies the brake and make time of the delivery dial pulse. The signal PCS is fed to the AND gate AG provided btween FF-A and the relay drive circuit RDA connected between the dial pulse outgoing trunk OGT and the signal driver SD so that the operation of the relay A is independent of the central control unit and the timing can be finely tuned. The monitor of the delivery control signal is made at the central control unit and the processed load of the central control unit is reduced. |
