The over current monitor may only be installed in rectifiers that are employed in modern process engineering in the fields of copper-plating, nickel-plating, chromium-plating, anodising, manufacture of printed-circuit boards and galvanisation.
The overcurrent monitor measures the voltage at the shunt. If the shunt voltage exceeds a set value, a comparator changes over and starts a ramp-function generator. After a certain time delay, the output relay is changed over. If the overcurrent has decreased to a value below the set operating point before the ramp-up time of the integrator has been reached, the ramp-function integrator will be reset and the output relay will not change over. In case of a new over current, this process is started again. If a very high over current occurs, the output will be changed over without the time delay of the integrator.
