[Cause]
An abnormality in the DCS parameter was detected.
- After executing the application to the DCS parameter, after the DCS parameter confirmation interface is displayed, and the power is turned on again without pressing "F4(OK)", this alarm will occur.
- This alarm is issued when Yes is selected in the initialization of DCS during image recovery.
- When performing image restoration, when No is selected in the initialization of DCS, this alarm will be issued if the DCS parameters before restoration are different from the security parameters in the image file.
- If "Unable to apply to SYST-289 DCS parameters" occurs when applying to DCS parameters, this alarm will occur after the power is turned on again.
- This alarm occurs when the settings are changed on the DCS interface and the alarm "Please apply to SYST-212 DCS parameters" occurs, but instead of executing "Apply to DCS parameters", an automatic software update is performed.
[Countermeasure]
1. Please apply to DCS parameter.
2. Load backup data.
3. Replace the CPU card. Before performing countermeasures 4 and 5 below, be sure to obtain an image backup of the controller.
4. Replace the FROM/SRAM module and restore the obtained image backup.
5. Replace the mainboard and restore the obtained image backup.
Note To clear this alarm, power needs to be cycled.
