The status bar also has an alternate function where it dis-
plays to the user any information that requires user at-
tention or intervention. It accomplishes this by changing
the status bar’s color and/or fl ashing a additional infor-

• Indicates a condition where the compressor motor is
not running.

• Informs the operator that the compressor motor is
currently running.

of the status bar. The operator will see the status bar
and then one or more information bars in a repetitive
sequence.
Information Bar – blue:
• Shows various operational modes that are different
than normal running condition. An example of this
would be a load limit condition. The compressor is
not able to completely load due to some parameter
like high motor current and therefore the operator is
notifi ed via this type of information bar.

conditions do not stop the compressor but it is meant
to alert the operator of conditions that if corrective
action is not taken, then a compressor trip can result.

• Informs the operator that the compressor motor
was stopped due the condition listed in the informa-
tion bar. Compressor trips are designed to protect
the equipment and any personnel operating the
equipment.
