These compressors are known for high efficiency, capacity

A linear potentiometer tracks the exact physical position of the slide valve. If your control panel reports inaccurate capacity percentages, recalibrate the potentiometer according to the service manual instructions. 5. Troubleshooting Common HSA Technical Issues Low Oil Pressure Trip Possible Cause: Clogged oil filter element.

: If a compressor fails to load or loads unwantedly to 100%, technicians perform field tests to check solenoid sealing and the movement of capacity slides. Oil Management
