LDMCR on A343. What is it?

[SubsonicMortal]

Doing a type conversion onto the A340-300 and came across a note w.r.t an IDG OVHT condition. No where in FCOM 1 can I find a definition for LDMCR. The note says "If the IDG 3 or IDG 4 is inoperative the heating of the INOP SYS LDMCR is lost"

Any clues?

Excellent, thank you for the info. A picture speaks a thousand words!

Many moons ago, I was a jockey on 340, but this I didn't know.

How does it work?
