Re: compressors
Dear Tom,
I looked around and saw strobe pulses but difficult to judge for ECL signal
without a well adapted probe. Then it remind me that I had the same problem in
Louvain after the lightening. I taught it was the SIS that couldn’t take data
anymore. This evening I went back to the history... and observed that the
controller in the compressor system is presently the same that was present
during the lightening. Could it be guilty even if well functioning on all
other actions?... I exchange withy an other one... and GOSH .... the SIS is
filling and I reach the half full state.
Conclusion
1) One component burnt into the compressor exposed to the lightening
2) May be the SIS3600 in LLN is still alive..
I tried unsuccessfully to reach you by phone...
Can you test again remotely? The compressor is running in test mode in quite a
fast rate and in the continuous mode. So you can test when you wish until we
wake up tomorrow.
Note: .. mozella went out!
Let me know your success if any.
Best regards
René.
