To Access: Press ALT. MODE key
CODE #	TITLE	DESCRIPTION
		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
	Recorder Supply	determined there is a fault with this sensor.
AL70	Temperature Out of	NOTE
	Range
		The P5 Pre-Trip test must be run to inactivate the alarm (refer to section
		3.2.1).
		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
	Recorder Return	determined there is a fault with this sensor.
AL71	Temperature Out of	NOTE
	Range
		The P5 Pre-Trip test must be run to inactivate the alarm (refer to section
		3.2.1).
AL72-74	USDA Temperatures 1,	The USDA probe temperature reading is sensed outside of range.
	2, 3 Out of Range
AL75	Cargo Probe 4 Out of	The cargo probe temperature reading is sensed outside of range.
	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	The network sensor is outside of its specified range. See NOTE below.
	Out of Range
		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.
		An invalid date or time has been detected. This situation may be corrected
AL87	RTC Failure	by changing the Real Time Clock (RTC) to a valid value using the
		DataView.
AL88	DataCORDER	A write of critical DataCORDER information to the EEPROM has failed.
	EEPROM Failure
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).
