MORE OFTEN THAN NOT any "Runtime Alert ####" on an 890 is indicative of some sort of lower-level hardware issue that is normally solved by replacing hardware. However there was a bug when connecting to an 890 drive when using DSE v3.10 (not DSElite) that occasionally caused an erroneous RUNTIME ALERT error. Normally, RUNTIME ALERT 0x003H.
If you see a "Runtime Alert ####" occur when connecting to an 890, or attempting to download a project into an 890, then check the version of DSE you are using. If using DSE v3.10, you should upgrade to v3.11 or later by following this FAQ article: How do I update my DSE software?
Then reattempt the connection to your drive and redownload the project that was originally used inside the drive. If the issue is resolved after doing both of those things, then the bug was manifesting and should now be squashed. However, if you upgrade to DSE v3.11 or later and the issue continues to persist then there truly is a fault present that will likely require a control board replacement.
If you originally saw a RUNTIME ALERT during any other point of operation (when not using DSE to connect or download to the drive) then this is not likely to resolve your issue, and a new control board is likely required. Contact Parker Applications for assistance.
