Looing for REM543 Functionality Description Manual

[yinhu32701]

Dear all,


For an ongoing project, I was assigned to check some of the old protection system installed backed in 2007. most of the diesel generator has equipped with REM543 type of protection, it was found on site that these relay did not set for a couple of important protection functions (including UE， NPS etc).

I have tried to look for a detailed description of the relay functions (luckily on this webiste I found UE protection manuals, but only partially); Wondering anyone could help me out? A full functional description manual would definitely help (Diff6G, UE, NPS, VOC， FREQ1 etc)

The manuals are on this page, plus a load of additional supporting information:

Hi ScottyUK

Unfortunately, the manual on the page contains only general information. I actually found quite some useful application note regarding (Diff6G, UE, NPS, FREQ1 functions)

I am still particularly looking for functional description of REF and VOC function.
