mV Sensor Cali- bration Needed
mV Latching
When user changes sensor type or gas
1=new sensor, 2=changed personality, 3=changed gas
Generated after accepting a new mV sensor or changing the mV sensor type or changing the mV gas selection. This is a warning to user that a span calibration should be performed. If a span calibration is not performed, the default calibration values will be used.
W023
Low Optical Sample Signal
Excel Non-latching
XNX polls sensor every 2 seconds, diagnostic frequency controlled by sensor
Sensor fault or warning code (Note 4)
Check location for external interference or obstructions in the IR path. Check sensor for dirty windows. Check Excel alignment. Check Beam Block Low Signal Percentage setting in the transmitter.
W024
Reflex Failure Warning
ECC Latching
Dependent on sensor, typically 8 hours; Once fault is de- tected: every 15 minutes
0 ECC sensor is nearing end of life. Replace sensor.
