Question

Is it acceptable to wire 61F's Floatless Level Controller electrode cable and power cable in the same duct?

Answer

There is a possibility of improper operation, so avoid wiring the cables in the same duct or close together.

Since there is a weak current (about 1 mA at 8 VAC) between the 61F Controller and the electrodes, the electrode cables can be affected by inductive noise from the power cable and operate improperly. Also, be sure to check that the common electrode is grounded properly.
