Alarms - All Groups
Alarm Severity
Red LED - Critical Alarm: The controller will attempt to safely pump down the suction group. The group is unable to run safely with a critical
alarm, and the controller will cease refrigeration for that group. The controller is attempting to prevent a catastrophic system failure, such as
damage to the compressors. Critical alarms should be addressed immediately.
Yellow LED - Cautionary Alarm: The controller will continue to function to the best extent possible given the system conditions, but the
alarm should be addressed as soon as possible.
