In a recoverable operating error, XD ONE logs the event and automatically takes appropriate action to resolve it.
After recovery, check previous data capture and device settings before continued operation. User configuration may need to be redefined in BreatheLITE.
For a non-recoverable fatal error, XD ONE stops normal operation and alerts the user with flashing red LEDs and an audible sequence.
The manual recommends contacting the Trolex service team for support.
Internal memory corruption means corruption has been detected and data loss has occurred or readings cannot be recovered.
The device automatically formats its memory and continues operation.
If XD ONE internal memory is full, download and clear XD ONE data, event logs, and alarm logs.
Confirm important data has been downloaded before clearing stored records.
A particulate sensor data error means corrupt data was received from the particulate sensor. XD ONE ignores the reading, logs the event, and continues operation.
If this occurs more than four times, the device alerts the user and enters an error state. Contact Trolex or an approved distributor.
This fault means corruption was detected in the XD ONE settings.
The device automatically reverts to factory defaults and continues operation, so check and reapply required configuration in BreatheLITE.
This fault means XD ONE has detected an electronic hardware failure of the particulate sensor.
The device alerts the user and enters an error state. Contact Trolex or an approved distributor.
This fault means XD ONE has detected an electronic failure of the internal memory.
The device alerts the user and enters an error state. Contact Trolex or an approved distributor.
If XD ONE returns a fail result, it checks whether the fault is recoverable and repeats the self-test up to four times.
If a fatal error indication remains, the manual recommends contacting the Trolex service team.
XD ONE initiates automatic low-power shutdown and runs the power-off sequence. If the device is powered on without sufficient charge, it immediately runs the shutdown sequence again.
Charge the device before attempting to restart monitoring.
