Description Recommended Actions
Range Underow
Off-spec
Gas concentration is out of
measurement range and the-
refore linearization curve does
not apply (measuring results
are not reliable).
• Select lower range (polyno-
mial linearization mode only)
• Adjust gas concentration to
be within range
Secondary Sensor Signal
Simulation
Function check
Any secondary sensor’s
signal is simulated for service
purposes
• Restart device.
• Ask service personnel to
deactivate simulation.
Sensor ADC
Failure
Input voltage applied to an
internal DC signal input (DC
1...5) too high
• Adjust sensors output volta-
ge to be within 0 .. 5 V limit
• Replace sensor
Input voltage applied to an
internal AC signal input (WS
1...4)too high
• Adjust sensors output volta-
ge to be within ± 6 V limit
• Replace sensor
Sensor Chopper
Failure
Internal failure bit of electro-
nics board XSP is set
• Switch analyzer off and on
again
• Check red LED on chopper
board UCC
• Replace chopper
Sensor Communication
Timeout
Failure
The serial communication bet-
ween the main controller and
the sensor interface has timed
out. The reason is unknown.
Check both boards, and pro-
per connections
Sensor Detector
Failure
XSP's failure bit was set
• Switch off / on the analyzer
• Check if VVS signal is proper
• Replace detector
Sensor Flow
Failure
The ow sensor is not working
properly
Check the sensors function,
and if need be, replace the
sensor.
Sensor Pressure
Off-spec
The pressure measurement is
not working properly for com-
pensation purposes
Congure pressure to be
within limits
Sensor Signal Simulation
Function check
The primary sensor signal is
simulated for service purpo-
ses
• Restart device.
• Ask service personnel to
deactivate simulation.
