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 PreTrip 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

dAL7274
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

dAL76, 77
Future Expansion
These alarms are for future expansion, and are not in use at this time.
dAL7885
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.
A real time clock failure is critical to the operation of the unit. If this alarm oc-
curs, replace the RTC battery at the next available opportunity. After replac-
ing 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 nonvol-
atile 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).
