Maintenance
If a sensor is in Diffusion Supervision Fault, the device will still allow the user to attempt to calib-
rate the sensor. In the rare event that a sensor calibration is successful, but the Diffusion Super-
vision system continues to detect a blockage in the gas path, the Diffusion Supervision Fault
will return in approximately 24 hours. In this scenario, there is likely an environmental factor
affecting the Diffusion Supervision detection. Provided the sensor can successfully calibrate,
the sensor is still capable of detecting gas. To prevent the Diffusion Supervision Fault from
reoccurring, a user can either disable Diffusion Supervision in the Sensor Settings or replace
the sensor.
6.4 Troubleshooting
Table 17 below lists all fault messages, their priority levels, and corrective actions required to
resolve them. The faults are listed in alphabetical order. Lower priority messages are output only
after the highest priority message is cleared.
