Table 4-10 Datacorder Alarm Indications - Carrier PrimeLINE Operation And Service Manual

Code Description
dAL70 Recorder Supply Temperature Out of Range
The supply recorder sensor reading is outside of the range of -50°C to 70°C (-58°F to +158°F), or the
probe check logic has determined there is a fault with this sensor.
NOTE: The P5 pre-trip test must be run to inactivate the alarm.
dAL71 Recorder Return Temperature Out of Range
The return recorder sensor reading is outside of the range of -50°C to 70°C (-58°F to +158°F), or the
probe check logic has determined there is a fault with this sensor.
NOTE: The P5 pre-trip test must be run to inactivate the alarm.
dAL72-74 USDA Temperatures 1, 2, 3 Out of Range
The USDA probe temperature reading is outside of -50°C to 70°C (-58°F to +158°F) range.
dAL75 Cargo Probe 4 Out of Range
The cargo probe temperature reading is outside of -50°C to 70°C (-58°F to +158°F) range.
dAL76, 77 Future Expansion
These alarms are for future expansion and are not in use at this time.
dAL78-85 Network Data Point 1 - 8 Out of Range
The network data point is outside of its specified range. The DataCORDER is configured by default
to record the supply and return recorder sensors. The DataCORDER may be configured to record up
to eight additional network data points. An alarm number (AL78 to AL85) is assigned to each
configured point. When an alarm occurs, the DataCORDER must be interrogated to identify the data
point assigned. When a humidity sensor is installed, it is usually assigned to AL78.
dAL86 RTC Battery Low
The real time clock (RTC) backup battery is too low to adequately maintain the RTC reading.
A real time clock failure is critical to the operation of the unit. If this alarm occurs, replace the RTC
battery at the next available opportunity. After replacing the battery the following actions are required:
• Update the RTC setting
• Update the unit's software configuration
• Update the operational software
• Update all user selectable function code settings (defrost, setpoint, etc)
dAL87 RTC Failure
An invalid time has been detected. Either the DataCORDER run time hour and minute have not
changed at the start of the hour, or the real time clock (RTC) time has gained or lost more than 2
minutes in the hour. This situation may be corrected by cycling the power, setting the clock or meeting
the above criteria for an hour.
dAL88 DataCORDER EEPROM Failure
A write of critical DataCORDER information to the EEPROM has failed.
dAL89 Flash Memory Error
An error has been detected in the process of writing daily data to the non-volatile FLASH memory.
dAL90 Future Expansion
This alarm is for future expansion, and is not in use at this time.
dAL91 Alarm List Full
The DataCORDER alarm queue is determined to be full (eight alarms).
