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.
