Teledyne API Model 200AU NOX Analyzer Instruction Manual, 02293, Rev. F

Table 9-2: Front Panel Warning Messages

Message

Description

SYSTEM RESET

Analyzer was reset/powered on. This warning occurs every

 

time the instrument is powered up, as in a power failure. It can

 

also occur if the RAM or EEPROM is reset.

 

 

RAM INITIALIZED

RAM was erased. The RAM contains the DAS averages which

 

get erased when the RAM is initialized. It also contains

 

temporary data used by the M200AU to calculate

 

concentrations. No setup variables are stored in the RAM.

 

 

SAMPLE FLOW WARN

The calculated sample flow is outside the hi/low limits. Since

 

the flow is calculated, it probably means the pressure has

 

gotten too low. Flow warnings are caused by a plugged sample

 

inlet or ozone line.

 

 

OZONE FLOW WARNING

Ozone flow out of spec. Warnings occur most often because of

 

loss of vacuum, which causes the ozone flow to go to zero.

 

They also can occur due to a flow sensor failure.

 

 

RxCELL PRESS WARNING

Vacuum out of spec. Warnings are caused by leaks, pump

 

failure or disconnected pump.

 

 

BOX TEMP WARNING

Box temp. out of spec. Instrument fan failure, enclosure

 

temperature failure. Operation of the M200AU in a too warm

 

or cold environment will cause degradation of data quality and

 

shorten the life of the instrument.

 

 

RCELL TEMP WARNING

Reaction cell temp. out of spec. The warning message is most

 

often present during initial warm-up or if the connector to the

 

heaters is not plugged in after dis-assembly. It has also

 

occurred if the thermistor is not in position in the reaction cell.

 

 

PMT TEMP WARNING

PMT temp. out of spec. The PMT temp has its own

 

proportional controller on the preamp board. Warnings might

 

occur during warmup. A warning can occur if the 7 pin

 

connector to the interior of the sensor is not plugged in. The

 

power connector to the PSM should be checked for proper

 

voltage (+15 VDC ± 0.5)

 

 

MOLY TEMP WARNING

Molycon temp. out of spec. The Moly temp is controlled by

 

the CPU. It has a thermocouple with amplifier on the

 

Status/Temp board. Because of the high temperature of the

 

Moly (315° C), the moly temp warning will tend to be the last

 

warning to clear as the instrument is powered on.
