on the display directly below the screen. If the delivery pressure is below
the load pressure setting, the compressor will start and accelerate the motor, then open the inlet valve
and begin building pressure. If this is the first time that the compressor has been started, make sure that
all systems are working properly (refer to the machine service manual for more information).

9.2 Running
When running under the Automatic Operating Mode and control settings, compressor operation will
continue as described below:
The controller will attempt to keep the pressure within the set pressure band.
If the machine is a variable speed system, the motor speed will be adjusted to attempt to keep
the delivery pressure at the target pressure setting.
If the delivery pressure exceeds the unload pressure setting, the controller will close the inlet
valve and the Status Message Bar will display information about the new running state.
If the pressure remains above the load pressure with the inlet valve closed for a set amount of
time based on the machine design, the controller will stop the motor until the delivery pressure
falls back below the Load pressure. While in this state, the Status Message Bar will indicate that
the machine is enabled and will start when the pressure requirement is met as shown in Figure
29.
