TITLE
DESCRIPTION
dAL70
Recorder Supply
Temperature Out of
Range
The supply recorder sensor reading is outside of the range of -50 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 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 DataCORD-
ER 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 config-
ured 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 meet-
ing 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).
