(Eventually I had Newell set my hydraulic pressure to 15 BAR per ZF. The system has been working perfectly. I was told the 275 psi was a mistake. I was also told the 250 psi is used because of leak down. I disagree otherwise the pressure sensor would not be 230 psi. I will eventually need to install a pressure sensor of around 200-210 psi. I believe there are failed pressure sensors because there is not an isolation valve to protect the sensor during the process used to pressurize and bleed the system.)
