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.
 Steady red: An indication that the control module has failed.
3.15 LEDs on the module to display the failure alarms
Two multi-color LEDs on the CoreSense front module display the failure alarms. The LED on the top is green/red
and the LED on the bottom is orange.
For warning/alert (green), trip (orange) 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 again 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 reset has been done.
