Section I V– Operating Procedures
Basic Controls:
2) START will start the compressor, if no fatal faults are present (open sensor or overloads etc).
NOTE:
The RUN STATUS LED will be ON to show that a start cycle is in progress. The compressor will not
start if the line pressure is above the load point; the compressor will start when the line pressure
drops below the load point. If the compressor is waiting to start, the 'Run Status' LED will flash
rapidly.
3) STOP will initiate a controlled stop on the compressor. The stop cycle will take about 5 seconds to
complete, as the system has to unload and blow-down prior to halting the motor.
4) UP and DOWN are used to select parameters in the setup menus.
5) RESET is used to clear fault or service conditions from the display panel.
System Indicators:
RUN STATUS indicates that the compressor is in a run state. Steady indicates that the compressor is
running. If this light is flashing, and the compressor is in a stopped condition, the compressor will re-
start at any time. This also indicates that the compressor is about to start, when the auto-restart option
is enabled.
LOAD/UNLOAD: The left-most digit on the numeric display will show 'L' when the compressor is
loaded, and 'U' when unloaded.
