GEH-1793 The AC voltage or DC current relays are adjusted to pick up at 70-80 percent of rating at rated frequency. The DC voltage relays are adjusted to pick up at 50-60 percent of rating when cold. After AC relays have been continuously energized for a few hours (minimum four hours) at rated voltage, the pickup and dropout voltages increase by 3.
GEH-1793 CONTACT CLEANING A flexible burnishing tool should be used for cleaning relay contacts. This is a flexible strip of metal with an etched-roughened surface, resembling in effect a superfine file. The polishing action is so delicate that no scratches are left, yet it will clean off any corrosion thoroughly and rapidly.
