Indicator LEDs
There are four status indicators that identify the current
operational status of the machine:
• Power-On Indicator (Blue) – Lights when power is
applied to the controller. It will blink slowly to indicate
that Automatic Restart After Power Failure is enabled.
• Automatic or Manual Run Mode Indicator (Green) –
Lights whenever the compressor is set to start and run
automatically. The light is constant whenever the
motor is running. The light will blink slowly if the com-
pressor motor is stopped while in Automatic Mode as
a warning that the machine may restart at any time.
The light may blink rapidly if a machine start is immi-
nent.
• Maintenance or Warning Indicator (Amber) - Lights
when recommended maintenance or service warning
is issued. In most cases, the machine will continue to
operate normally.
• Fault Indicator (Red) - Lights when a compressor fault
has occurred. The light remains steady and the com-
pressor remains inoperative until the fault condition is
corrected.
