Teledyne 9110T instruction manual Possible Warning Messages at Start-Up

Model 9110T NOx Analyzer			Getting Started
		Table 3-12: Possible Warning Messages at Start-Up
	MESSAGE	MEANING
	SYSTEM RESET1	The computer has rebooted.
	ANALOG CAL WARNING	The A/D or at least one D/A channel have not been calibrated.
	BOX TEMP WARNING	The temperature inside the 9110T chassis is outside the specified limits.
	CANNOT DYN SPAN2	Contact closure span calibration failed while DYN_SPAN was set to ON.
	CANNOT DYN ZERO3	Contact closure zero calibration failed while DYN_ZERO was set to ON.
	CONFIG INITIALIZED	Configuration storage was reset to factory configuration or erased.
	DATA INITIALIZED	DAS data storage was erased before the last power up occurred.
	OZONE FLOW WARNING	Ozone gas flow is too high or too low for accurate NOx, NO and NO2	readings.
		Ozone generator is off.
	OZONE GEN OFF 4	This is the only warning message that automatically clears itself.
		It clears itself when the ozone generator is turned on.
		Upon power up the Ozone generator will remain off for 30 minutes. This allows the perma-
		pure dryer to reach its working dew point.
	RCELL PRESS WARN	Reaction cell pressure is too high or too low for accurate NOx, NO and NO2 readings.
	RCELL TEMP WARNING	Reaction cell temperature is too high or too low for accurate NOx, NO and NO2 readings.
	IZS TEMP WARNING 5	IZS temperature is too high or too low for efficient O3 production.
	CONV TEMP WARNING	NO2 to NO Converter temperature too high or too low to efficiently convert NO2 to NO.
	PMT TEMP WARNING	PMT temperature outside of warning limits specified by PMT_SET variable.
	AZERO WARN [XXXX]	AutoZero reading too high. The value shown in message indicates auto-zero reading at
	MV	time warning was displayed.
	HVPS WARNING	High voltage power supply output is too high or too low for proper operation of the PMT.
	REAR BOARD NOT DET	CPU unable to communicate with motherboard..
	RELAY BOARD WARN	CPU is unable to communicate with the relay PCA.
	SAMPLE FLOW WARN	The flow rate of the sample gas is outside the specified limits.

1Clears 45 minutes after power up.

2Clears the next time successful zero calibration is performed.

3Clears the next time successful span calibration is performed.

4Clears 30 minutes after power up.

5Only Appears if the IZS option is installed.
