µP-T ALARMS
Alarms and Alarm Codes
If an abnormal condition is sensed by the microprocessor,
an alarm code is generated and saved in memory. There can
be more than one alarm present at one time. An alarm code
will remain in memory until it is cleared.
The Alarm icon will appear in the display to indicate that an
alarm has been sensed. If the alarm occurred during a Unit
Self Check, it will be preceded by a dash (-).
These alarm codes will direct a service technician to the
source of a problem. Always record any alarm codes
present, they will be invaluable to the service technician.
Displaying Alarms
If the Alarm icon appears on the display, press the Select
key to display the alarm. If more than one alarm is present,
they will “cycle” through the display, with each alarm
appearing for several seconds.
Clearing Alarms
To clear an alarm after the alarm condition is corrected,
press the Select key to display the alarm and then press the
Enter key to clear it. Repeat this process for any additional
alarms.
Types of Alarms
There are three types of alarms. They may occur individu-
ally or along with other alarms. There can be more than one
alarm present at one time. Alarms that occurred during a
Unit Self Check will be preceded by a dash (-).
• Stored Alarm. Indicates that a condition exists that
does not affect unit operation but that should be investi-
gated. The Alarm icon will appear for 30 seconds when
the unit On-Off switch is turned ON and then disap-
pear.
• Check Alarm. Notice to take corrective action before
an abnormal condition becomes severe. The Alarm icon
will appear and remain ON.
• Shutdown Alarm. Indicates conditions that may dam-
age the unit. The unit will automatically shut down, the
Alarm icon will appear and the entire display will flash
ON and OFF.
To view the complete list of possible alarm codes and their
definitions, refer to Section 3 in the Operation and
Diagnosis Manual (TK 41087).
