Abstract
PURPOSE:To aim at simplification in a controller by resetting a divider when pressure in a vacuum tank becomes less than the reference value, and driving a motor via a driving device, while when this pressure is reached to the reference value, stopping the motor after the elapse of the specified time. CONSTITUTION:When pressure in a vacuum tank becomes less than the reference value, a pressure switch is turned off, and since an actuation detector 10 outputs one signal, output of a divider 12 is reset to zero. With this, output of a reversing buffer 14 comes to 1 whereby a transistor Tr5 is turned on, a magnet coil 4 is excited and a normally opened contact 3 comes on, thus a motor 2 for vacuum pump driving is started. Afterward, when tank pressure is reached to the reference value and the pressure switch 7 is turned on, the divider 12 starts its clocking motion, and if time is up after the elapse of the specified time, the output of the reversing buffer 14 comes to zero, and the transistor Tr5 comes off, thus the motor 2 is stopped.
