1. A method comprising:
- monitoring a pressure of compressed air within a reservoir that is fluidly connected to a compressor;
actuating an unloader valve of the compressor by cycling the unloader valve between an open position and a closed position of the unloader valve during a time period;
correlating the monitored pressure of the compressed air within the reservoir during the time period with the open position of the unloader valve and the closed position of the unloader valve;
detecting a leak condition during the time period by determining a difference between a rate of change of the monitored pressure of the compressed air within the reservoir while the unloader valve is in the open position and a rate of change of the monitored pressure while the unloader valve is in the closed position; and
automatically generating a signal in response to detecting the leak condition to one or more of notify personnel of the leak condition or control the compressor based on the leak condition that is detected.

Abstract
Systems and methods of the invention relate to diagnosing a compressor. A method may include monitoring a pressure of compressed air within a reservoir of a compressor, actuating an unloader valve of the compressor, and detecting a leak condition of the compressor through recognition of a change in the monitored pressure of the compressed air within the reservoir during a time period in which the unloader valve is actuated. A system is also disclosed including an engine, a compressor operatively connected to the engine, and a controller that is operable to determine a condition of the compressor.

15. A controller that is operable in association with a compressor, wherein the controller is configured to:
-
receive a signal corresponding to a monitored pressure of compressed air within a reservoir that is fluidly connected to a compressor; actuate an unloader valve of the compressor by cycling the unloader valve between an open position and a closed position of the unloader valve during a time period; correlate the monitored pressure of the compressed air within the reservoir during the time period with the open position of the unloader valve and the closed position of the unloader valve; detect a leak condition during the time period by determining a difference between a rate of change of the monitored pressure of the compressed air within the reservoir while the unloader valve is in the open position and a rate of change of the monitored pressure while the unloader valve is in the closed position; and automatically generate a signal in response to detecting the leak condition to one or more of notify personnel of the leak condition or control the compressor based on the leak condition that is detected. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. A system, comprising:
-
an engine; a reservoir configured to store compressed air; a compressor operatively connected to the engine and fluidly connected to the reservoir, the compressor configured to supply compressed air to the reservoir, the compressor including an unloader valve configured to release pressure from a portion of the compressor; and a controller configured to; receive a signal corresponding to a monitored pressure of the compressed air within the reservoir; actuate an unloader valve of the compressor by cycling the unloader valve between an open position and a closed position of the unloader valve during a time period; correlate the monitored pressure of the compressed air within the reservoir during the time period with the open position of the unloader valve and the closed position of the unloader valve; detect a leak condition during the time period by determining a difference between a rate of change of the monitored pressure of the compressed air within the reservoir while the unloader valve is in the open position and a rate of change of the monitored pressure while the unloader valve is in the closed position; and automatically generate a signal in response to detecting the leak condition to one or more of notify personnel of the leak condition or control the compressor based on the leak condition that is detected. - View Dependent Claims (24, 25, 26)
