Compressor Unloading

If the value of the control signal exceeds the set point, the compressor will use load pulses to move the slide
valve. Conversely, if the value of the control signal falls below the set point, the compressor will use unload
pulses to move the slide valve.

Reverse

Reverse acting capacity control manages the compressor control pulses via a time-proportioning scheme, as
illustrated below.
