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 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 Data
-
CORDER is configured by default to record the supply and return re
-
corder 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 Data
-
CORDER 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 opportu
-
nity. 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).
