CODE # TITLE 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 sensed outside of -50 to 70°C (-58
to 158°F) range.
dAL75
Cargo Probe 4
Out of Range The cargo probe temperature reading is outside of -50 to 70°C (-58 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 8 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.
dAL87 RTC Failure
An invalid date or time has been detected. This situation may be corrected
by changing the Real Time Clock (RTC) to a valid value using DataLINE.
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).
