Shutdown Alarms
Shutdown alarms (also know as “Stop Alarms” or “Safeties”) execute rapid compressor
shutdown and require manual reset. They are also logged in the Alarm Log.
The following table identifies each equipment protection alarm, gives the condition
that causes the alarm to occur, and states the action taken because of the alarm. If the
alarm is auto-clearing, the reset condition is also shown. Otherwise, the alarm is
manually reset, requiring the operator to clear the alarm.
