Compair Delcos 1000 Bis Manual Top !link! < Popular - 2027 >
In the world of industrial rotary screw compressors, the CompAir Delcos 3100, 5100, and 1000 series have long been industry standards for reliability and digital control. Among these, the CompAir Delcos 1000 BIS stands out as a workhorse controller found on thousands of Delcos and other CompAir models manufactured in the late 1990s and early 2000s.

Whether you are troubleshooting an inlet valve, performing a pressure test, or simply verifying the controller's outputs, the manual top mode is your most powerful diagnostic tool.

Activating forces the compressor into one of three manual states: A. Manual Load (Forced Load) Even if the line pressure exceeds the cut-out setpoint, the compressor will keep the inlet valve open and deliver air. Use this for testing, blowing down lines, or emergency supply overriding the regulator. B. Manual Unload (Forced Idle) The compressor runs but the inlet valve closes (screw compressor unloaded). This reduces power consumption to ~20-30% of full load. Useful for immediate pressure reduction during system over-pressurization without stopping the motor. C. Manual Stop (Emergency Override) Directly commands a controlled stop sequence (drain valves open, motor contactor opens). Different from the red emergency stop, this respects timer delays.
