Device alerts are warnings and errors that communicate potential problems with the DGA monitor device. Device alert status is shown in the header at the top of the user interface. A message that describes the alert is also shown.
Device alerts come in two severities:
- Warnings are less serious and may not require any action to be taken.
- Errors typically prevent normal measurement and require user intervention to recover from.
Contact Vaisala for support if you are unable to resolve a device alert yourself. From the Service page of the user interface you can create a diagnostic data file that can help Vaisala diagnose the device alert. It is recommended that you do this if your DGA monitor stops due to an error, regardless of if the error was successfully resolved.
|1098||Measurement cycle started after an error||Warning||
The measurement cycle has been started after an error. It is yet unclear if the error has been resolved and the measurement cycle can be completed successfully. Please wait.
This warning is inactivated once the measurement cycle has been completed successfully.
|1401||Unable to measure due to unstable temperature||Warning||
Results of the latest measurement cycle have been rejected due to unstable temperature. This is typically caused by the cabinet door being left open.
|1402||Unable to measure due to unstable light intensity level||Warning||Results of the latest measurement cycle have been rejected due to unstable intensity level of the optical measurement module. Contact Vaisala support if this warning repeats for many measurement cycles.|
|1501||Hardware clock time lost||Warning||
Hardware clock of the DGA monitor has incorrect time. Set new time or enable time sync in thepage.
If this error reoccurs, consider changing the backup battery of the real-time clock. Contact Vaisala support for help with changing the backup battery.
|1502||Unable to read measurement module calibration file||Warning||The system is unable to read the calibration file of the optical measurement module. DGA monitor continues measuring without the optical measurements. Contact Vaisala support.|
|2099||Measurement cycle fault||Error||
If the DGA monitor has a serious hardware problem or cannot measure due to some external cause, it will automatically stop trying to run the measurement cycles. See Resolving a measurement cycle fault
|2102||Oil inside cabinet||Error||The float sensor inside DGA monitor cabinet is activated, indicating a possible oil leak. It is recommended to check the device right away. Inspect inside the DGA monitor and oil lines to determine the cause of the error, and remove it if possible.|
|2112||Excess gas in the system||Error||
There is excess gas in the measurement system, and the DGA monitor is unable to safely dissolve the gases back into the oil.
You must bleed the excess gas from the system to resume normal operation. See Bleeding the DGA monitor.
|2200||Valve 2 failure||Error||
If the lock is open the valve must be replaced to resolve the error. Contact Vaisala support.
