Possible Alarms and Events
There are three types of alarms: faults, problems, and warnings. In addition to these three alarms, there are also "events." See
the following tables for examples of faults, problems, warnings, and events that can occur. Separate tables are shown based on
whether the alarm source is the unit or the compressor.
NOTE: In the "Alarm Reset" column of the following tables, itallics indicate special alarm conditions or severity. If the "Alarm
Reset" says "Auto-clears," it indicates that the alarm will auto-clear after the condition is resolved and the normal
condition returns.
Fault Alarms
Equipment protection faults cause rapid compressor shutdown. The compressor is stopped immediately (if the compressor was
running).
