Alarms

Info Log

Info Log events serve as a notice to take corrective action before a problem becomes severe. Maintenance items such as maintenance hourmeter time-outs are Info Log events. The TemperatureWatch screen is not disabled if only Info Log event(s) are active.

When the unit is turned on, the display will show the Thermo King Logo and then the Configuring System message. The Info Log event notification will appear on the Standard Display.

An Info Log event is indicated by an "information" notification on the display located next to the setpoint. The Info Log event icon will appear.

Check Alarm

A Check alarm is indicated by a check alarm notification on the display located next to the setpoint. The Check alarm icon will appear. 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. If a Check alarm condition occurs while the unit is running, the alarm icon will appear in the display.

Prevent Shutdown Alarm

A Prevent Shutdown alarm is indicated by an Alarm Active enlarged red icon in the center of the display. The Alarm Active icon will appear. The unit will be temporarily shut down if a Prevent alarm is active. The unit will remain shut down for a timed restart interval or until the fault conditions are corrected and then restart. In some cases, the unit will restart with reduced performance to determine if continued operation is possible. If the alarm does not reoccur with reduced performance, the unit will return to full performance. In general, if the alarm condition reoccurs a defined number of times, the alarm is set as a Shutdown alarm and no further restarts are possible.

Note If the Restart After Shutdown feature in the Guarded Access Menu is set as DISABLED, the control system will regard all prevent shutdown alarms as standard shutdown alarms.

Shutdown Alarm

A Shutdown alarm is indicated by an Alarm Active enlarged red icon in the center of the display. If a Shutdown alarm occurs while the unit is running, it will be indicated by all of the following:

  • The Alarm Active icon will appear.

  • The optional remote alarm light will flash on and off.

Shutdown alarms will force the unit into shutdown. The unit will remain in shutdown until the Shutdown alarm is manually cleared.
