Making adjustments to GEC CDG36 (or CDG31) relays
Making adjustments to GEC CDG36 (or CDG31) relays
(OP)
Hi
Does anyone have a manual for the GEC CDG36 (or CDG31 Relay) that they could link me to?
We have several relays that have shown up as not quite following the curves and need some tweaking. I remember having some literature a long time ago of which screw to adjust to alter which setting (moving magnets across the disc etc), but I can't find it any longer.
I have tried the Alsthom and Schneider websites and sent them emails asking, but so far no luck in hearing back from either.
The main issue appears to be with the PU (and the timing at the lower end of I) and I vaguely remember twiddling a few screws to correct this years ago.
Thanks
Peter
