<p>An improved method and apparatus for adjusting the space between an adjustable anode set and a cathode in an electrolytic cell to protect the electrodes from current overloads and current underloads wherein an amplified current signal for each anode set is obtained, an average current determined, and a collective current, proportional to the average current, generated. A first portion of the collective current is individually selected for each anode set as an upper reference signal and a second portion of the collective current is individually selected for each anode set as a lower reference signal, the difference between the upper reference signal and the lower reference signal being the operating current range. Comparison of the amplified current signal for an anode set is made with its upper and lower reference signals and the anode-cathode spacing adjusted when the amplified signal falls outside of the operating current range.</p> |
