Help with McQuay ALSO70

[darooo]

I am new to this site, looking for some help on a McquayALSO70 chiller that continously trips on fail to prepurge, Ive learned that it must get below 40 psi in 45 seconds, but never does, I have tested EXV and is working properly, any other asvice anyone has would be great, I am a 25 year vetern in the trade but is my first McQuay chiller. Thanks

Have you checked the gates yet as suggested in the other forum that you posted this question on yesterday?

A lot of details missing from your question also.
