Table 2-1: Control State Definitions
Control State
Definition
Reset
The controller is resetting
Auto Restart
Auto Restart is enabled and active. The compressor will transition states at the expiration of the
Auto Restart Timer
.
Shutdown
A shutdown fault is active.
Ready
The compressor is healthy and ready to be enabled.
Remote Halt
The compressor has been halted by a remote signal.
Ask to Start
The compressor is attempting to start. Prolonged time in this state indicates that a precondition to
starting the compressor has not been met.
Enabled
The compressor is enabled and may start automatically when all starting conditions, such as
pressure setpoints, have been met.
Ask to Load
The compressor is attempting to load.
Pre-Wye
Initiating wye-delta start
Wye
Motor contactors have been engaged in the Wye (Start) connection.
Delta
Motor contactors have transitioned to delta connection.
Start
The motor has been started and the compressor is beginning the loading process
Pause
The motor has been started and the inlet valve has been opened but the controller is waiting on a
condition to be met before transitioning to the loaded state. Dwelling in this state may be due to low
reservoir pressure or the start timer.
Loaded
The compressor is loaded and operating, and will unload once the
Unload Pressure
has been
reached.
Unload
The compressor is in the unloaded state. Transition into this state triggers the blowdown timer to
start. The compressor will transition to loaded if delivery pressure falls below the
Load Pressure
setting or to blowdown state if the blowdown timer expires.
Blowdown
The compressor is in the blowdown state. Pressure will be relieved from the air/oil reservoir.
Transition into this state triggers the auto timer to start. The compressor will transition to loaded if
delivery pressure falls below the
Load Pressure
setting, or to enabled if the auto timer expires.
Normal Stop
The controller is executing the normal stop sequence. The motor will continue to run during this
state until all conditions for stopping have been met, including the stop timer.

The
Dynamic information
line on the home screen is used for various informational messages
depending on the state and condition of the compressor. If no other information is being displayed,
this line will show the current date and time setting on the controller. Table 2-2 describes the various
information that will be displayed here:
