Fault Indication Diagnosis
The following fault indicator functions will be held in mem-
ory and displayed on the temperature readout display when
the Alarm [CODE] key is pressed. There are several alarm
types that can be indicated by the controller.
SHUTDOWN ALARMS
Shut down alarms will turn the unit off immediately upon
detection. They are indicated by a flashing alarm symbol.
Shutdown alarms must be corrected and cleared before the
unit can be restarted.
NOTE: It is possible to clear a shutdown alarm with the
unit switched of]; however the unit will shut down again
when the alarm reoccurs.
CHECK ALARMS
Check alarms act as prompts to take corrective action before
a problem becomes severe. They are indicated by steady
alarm symbol. They may be cleared, but will reoccur until
corrected.
STORED ALARMS
Stored alarms are indicated by a steady alarm symbol that is
displayed for 30 seconds after the On-Off switch is turned
ON.
After 30 seconds, the Stored Alarm will disappear from the
display.
View and write down each fault code as it is displayed.
When all codes have been viewed and correct (serviced or
repaired), press the CLEAR key to clear each alarm from
the display.
