Zusammenfassung: | PURPOSE:To locate a rod accurately with a motor, by connecting a relay contact a to a power supply and contact b to an earth and a terminal of the motor. CONSTITUTION:RS flip-flop 64 gives the output of Q terminal of an amplifier through OR gate 65 to connect a relay 67 to a contact a and operate a motor 22. A rod 18 is lifted to the releasing position by the operation of the motor 22. When RS flip-flop 56 is reset, a counting circuit 57 is cleared to stop the counting operation. When RS flip-flops 60, 64 are reset, respective Q terminal outputs reach L level. Thus, since the amplifier 66 is turned OFF, the relay 67 is changed over from the contact a to b and both terminals of the motor 22 is shortcircuited through the relay so that the motor is quickly stopped by the braking action. |
