PURPOSE:To prevent the malfunction due to noise signal, by inputting the reset signal while the set signal is input, in the flip-flop to turn on and off the exciter. CONSTITUTION:When the reset signal is input to the terminal 3, it is fed to the reset exciter 8 via the reset gate 7. The excitation of the reset exciter 8 is restored by flowing the required current to the coil 10-A in magnetic coupling with the core 9. The discharge circuit 20 discharges the charge stored in the capacitor of the integration circuit 17 connected to the monitor coil for the detection of exciting state. The cause of set due to the surge current can be prevented by applying the reset signal from the terminal (C) to the terminal (a) so that the flip-flop 5 for excitation set can not be set with the surge current produced at that time. |
