    • This invention discloses an electronic control system for an Industrial Motor Operator that uses standard steady state logic to improve reliability in rough service wet and dirty environments. It includes means of providing electronic snow limit to close limit sensing removing the need for two switches and radically improving its accuracy. A low voltage switch reverses the high voltage motor wires and at the same time reverses the open limit, close limit, and snow limit sensors mechanical positions. It discloses a system using lamps to indicate that the power wiring is connecting to three-phase motors in the correct sequence or that single-phase motors have their windings correctly phased.

    • When a cylinder is urged to displace a piston rod, and a pulse signal is inputted into a counter from an encoder, then the number of pulses of the pulse signal is counted by a counting section. A time-measuring section starts measurement for the elapsed time upon the start of operation of the cylinder. When the pulse signal is inputted, the elapsed time is reset. When the displacement of the piston rod is stopped, the pulse signal is not inputted. The elapsed time is increased to make coincidence with a predetermined preset time to output, to a control unit, a preset time elapse signal indicating this fact. At this time, the preset count value is compared with the count value of the pulse signal counted by the counting section. If the both are coincident with each other, a coincidence signal indicating this fact is outputted to the control unit. Accordingly, it is possible for the control unit to detect the stop of the cylinder and detect the displacement position of the piston rod at this time.
    • 当气缸被推动以移动活塞杆,并且脉冲信号从编码器输入到计数器中时,脉冲信号的脉冲数由计数部分计数。 时间测量部分开始测量圆筒运行开始时的经过时间。 当输入脉冲信号时,经过的时间被复位。 当活塞杆的位移停止时,不输入脉冲信号。 经过时间增加以与预定的预设时间一致,向控制单元输出指示该事实的预设时间过去信号。 此时,将预设计数值与由计数部计数的脉冲信号的计数值进行比较。 如果两者一致,则将表示该事实的一致信号输出到控制单元。 因此,控制单元可以检测气缸的停止并且此时检测活塞杆的位移位置。
