Device Faults Description Recommended Action
EE Fault Fault in non-volatile memory
Power may have been interrupted while the device
was updating its internal data logs. Recycle
power.
Ref ADC Sat
Sensor signal level is outside the range of the AD
converter
Return to factory.
Active ADC Sat
Sensor signal level is outside the range of the AD
converter
Return to factory.
24V Fault Problem in 24 volt power supply or power wiring
Check power wiring and output voltage of power
supply.
Flash CRC Fault Memory fault Return to factory.
RAM Fault Fault in volatile memory Return to factory.
low Voltage Power supply voltage outside of limits
Check power supply voltage.
Return to factory.
Temp Fault Temperature sensor fault Return to factory.

EE Safety Fault internal configuration fault Return to factory.
Gas Under Range Sensor signal has drifted negative
Device may have been calibrated with background
gas present. Recalibrate the detector. Purge with
clean air if needed.
Sensor Mismatch Wrong sensor type is installed
Sensor type must match configuration. Change
sensor or configuration.
ADC CnTR Fault internal hardware fault Return to factory.
