The Alarm List Menu displays alarms. Alarms are
recorded in the controller memory to simplify unit
diagnostic procedures. The alarms are listed in the
reverse order of their occurrence. The Alarm LED
flashes if a shutdown alarm is present. Enter the
Alarm List Menu to view the and acknowledge
the alarms.
Alarm Types
There are two types of alarms:
Delayed Restart Alarm:
Delayed restart alarms
indicate the unit has stopped temporarily because
of a problem or to prevent damage to the unit. The
unit will attempt to restart in 20 minutes. The
display will show information about the unit in
the message screen and the time left to the restart
attempt. A delayed restart alarm becomes a
shutdown alarm after the third failed restart
attempt in an hour.
Shutdown Alarm:
The Alarm LED flashes and unit
stops. Shutdown alarms indicate the unit has been
stopped to prevent damage to the unit. The
condition must be corrected before restarting the
unit.
