TITLE
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.
The P5 Pre-Trip test must be run to inactivate the alarm.
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.
The P5 Pre-Trip test must be run to inactivate the alarm.
The USDA probe temperature reading is sensed outside of --50 to 70°C
(--58 to 158°F) range.
The cargo probe temperature reading is outside of --50 to 70°C (--58 to
158°F) range.
These alarms are for future expansion, and are not in use at this time.
The network data point is outside of its specified range. The DataCORD-
ER is configured by default to record the supply and return recorder sen-
sors. 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 inter-
rogated to identify the data point assigned. When a humidity sensor is
installed, it is usually assigned to AL78.
The Real Time Clock (RTC) backup battery is too low to adequately main-
tain the RTC reading.
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.
A write of critical DataCORDER information to the EEPROM has failed.
An error has been detected in the process of writing daily data to the non-
volatile FLASH memory.
This alarm is for future expansion, and is not in use at this time.
The DataCORDER alarm queue is determined to be full (eight alarms).
