PIE Failure on Power up
I am getting a PIE failure on power up after the system has been off a period of time. It can take several days to get the error to clear. I have checked the vacuumm, the PC Software control software, and a scan of the internals is not reporting any errors other than this issue and it can be a bear to clear out. It is not a consistent problem. Just on start up after an "off" period.
Areas I am curious about:
1) Can the HV supply be out of tolerence?
2) Is it simply a warm-up period issue and we just need to give it time?
3) Is ist possible an interlock or safety feature is on the verge and needs replacing.
Thanks for any assistance.
