Table 9-9-2: 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 M200A 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. This can be caused by a plugged sample inlet,
or water in ozone line into the reaction cell.
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 M200A 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.
IZS TEMP WARNING IZS 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. Also check the
position of the thermistor in permeation tube heater block.
Check to see if there is a good seal at the top of the heater
block.
