| Oil – Variable Speed Pump – Setpoint Not Achieved | Shutdown of “P” compressors when the minimum allowed oil pressure is not achieved. | Oil pressure did not achieve the minimum allowed value during the last 10 seconds of System Prelube and the first 15 seconds of System Run. Previously the threshold was 25.0 PSID; effective October 2004 the threshold is 35.0 PSID, making it consistent with all other compressors. | 1 |
