CU 01

The electronic positioner CU01 is designed as a three level positioner for regulating of actuator.By comparing two input signals (reference signal W & regulating signal X), the positioner determines the difference. In case this exceeds a certain value, the actuator is switched on by relays. The direction of rotation (opening or

19

closing) depends upon the plus or minus sign of the deviation. Thus the regulating signal generated by potentiometer or LVDT changes & when the regulating signal & reference signal become equal, the actuator stops as long as no new correction is required.
