Mcquay Cond press high alarm

[Nuclrchiller]

You may want to get someone experienced to look at this chiller. Your "corrected" pressure indicates reverse flow. Perhaps language is an issue here. I only speak English. I'm sorry, but my faith in our ability to properly communicate on the internet and to accurately discuss your problem is weakened. Maybe others here will be better able to help. The chances of that will be greatly increased if you translate from metric. Good luck.
