York YK "D" fitted with VSOP.
Hello everybody! I'm troubleshooting a Centrifugal York Millennium YK “D” style, fitted with VSOP. What is happening is: when the equipment is requested to start, during the pré-lub process the oil pump starts and the VSOP output frenquency increase from 25 to 60 Hz, but the oil pressure do not reaches a value of 45 PSID as needed and the compressor start is aborted followed by the “ HIGH OIL FLOW” displayed message. After the VSOP reset, and several attempts, the pré-lub process is completed and the equipment starts. Has anyone ever seen this problem?
