ALARMS
Alarm Types
Alarms may be one of four types as shown.
Log Alarms
Log Alarms are indicated for 60 seconds each time the unit is turned on. This level of alarm serves as a notice to take corrective
action before the condition impacts unit performance. Maintenance items such as maintenance hourmeter time-outs are log
alarms.
When the unit is turned on the display will show the Thermo King Logo and then the "Configuring System" message. If log
alarm(s) are present the Log Alarm notice will appear on the display for 60 seconds as shown. The amber K symbol of the remote
indicator alarm light (if installed) will also be on during this period. The Premium Display will appear and the remote indicator
alarm light will go to the white T symbol after 60 seconds.
Note: The Alarm Icon does not appear on startup with log alarms present.
Log Alarm Notice
Note: If required, an engine start may occur while the display in Figure is shown. This is normal operation.
Check Alarms
Check Alarms are indicated by an Alarm Icon in the display. The amber K symbol of the remote indicator alarm light (if
installed) will be on. This level of alarm serves as a notice to take corrective action before a problem becomes severe. The unit
will run with check alarms but some features and functions may be inhibited.
Shutdown Alarms
Shutdown alarms will be set if continued operation could cause damage to the unit or the load. Shutdown Alarms are indicated
by the following:
• The Alarm Icon will appear in the display.
• The display and backlight will flash on and off.
• The display will switch from normal video to reverse video and back to normal video. (Light areas become dark and dark
areas become light.)
• The remote indicator alarm light (if installed) will display only a row of LEDs at the bottom.
Shutdown alarms will force the unit into shutdown to prevent potential damage to the unit or load. The unit will remain in
shutdown until the shutdown alarm is manually cleared. Exceptions are some engine and electric shutdown alarms that become
log alarms when switched to the alternate operating mode (diesel to electric or electric to diesel).
Zone Level Shutdown Alarms (SPECTRUM)
A Zone Level Shutdown Alarm will force the affected zone to shutdown, but allow the unit to continue to run as required by the host unit or
other zones.
• A small Alarm Icon will appear next to the affected zone
• and blink with a period of 1/2 second on - 1/2 second off.
• If a Zone Shutdown Alarm occurs in all zones then the
• unit will shut down and Alarm Code 114 Multiple Alarm
– Can Not Run will be set.
