3.14 Compressor status codes


Steady green: An indication of normal operation. There are no faults or issues with the compressor.

Flashing green: An indication that there is an alert (warning) condition. The compressor can still be
running.

Flashing orange: An indication that the compressor has tripped with auto reset.

Flashing red: An indication that the compressor is in lockout state.

Solid red: An indication that the control module has failed.

3.15 LEDs on the module to display the failure alarms

For warning/alert (green), trip and lockout (red), the flash count is defined as 0.1 second „on‟ and 0.4 second „off‟
with a 2-second pause before the flash count repeats (timings are +/- 50 ms).
Definitions:

Trip: The module has shut off the compressor due to a fault condition. The compressor will be available to
run when the fault condition no longer exists, and the minimum off time has been satisfied.

Lockout: The module has shut off the compressor due to a fault condition. The compressor will be
available to run again when the fault condition has been cleared and manual or remote reset is done.
