Looking for somebody with some really old notes. I'm trying to understand the operation of a GEIJD14B relay; the instruction bulletins (both GEH-931 from April 1934 and GEH-1151B with no date) have a description of operation that seems to require the knowledge of how many turns of the operate and restraint coils are in use for each tap. The description is talking about amp turns of restraint coil and amp turns of operate coil, but no table of coil sections. Does anybody have anything tucked away that would have that information? Thanks.
