DESCRIPTION
AL70
Recorder Supply
Temperature Out of
Range
The recorder supply air temperature is sensed outside of the range of
--50
_
C to 70
_
C (--58
_
F to +158
_
F) or if 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 (refer to section
3.2.1).
AL71
Recorder Return
Temperature Out of
Range
The recorder return air temperature is sensed outside of the range of
--50
_
C to 70
_
C (--58
_
F to +158
_
F) or if 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 (refer to section
3.2.1).
AL72-74
USDA Temperatures 1,
2, 3 Out of Range
The USDA probe temperature reading is sensed outside of range.
AL75
Cargo Probe 4 Out of
Range
The cargo probe temperature reading is sensed outside of range.
AL76, 77
Future Expansion
These alarms are for future expansion, and are not in use at this time.
AL78-85
Network Sensors 1 -- 8
Out of Range
The network sensor is outside of its specified range. See NOTE below.
NOTE
While the DataCORDER is normally setup to record only supply and return recorder sensors, the
DataCORDER has the capability to record the data of eight additional sensors. Any sensor installed on the
unit may be recorded, and are identifiable as Network Sensors AL 78 to AL85. Which alarm (AL78 to AL
85) is associated with the physical sensor, depends on how the DataCORDER was configured. To identify
which sensor is at fault, the unit must be interrogated to locate the sensor being recorded. Generally, the
humidity sensor is AL78, as it is the only network sensor recorded.
AL86
RTC Battery Low
The Real Time Clock (RTC) backup battery is too low to adequately
maintain the RTC reading.
AL87
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 the
DataView.
AL88
DataCORDER
EEPROM Failure
A write of critical DataCORDER information to the EEPROM has failed.
AL89
Flash Memory Error
An error has been detected in the process of writing daily data to the
non-volatile FLASH memory.
AL90
Future Expansion
This alarm is for future expansion, and is not in use at this time.
AL91
Alarm List Full
The DataCORDER alarm queue is determined to be full (eight alarms).
