User Interface Error Codes on ROSA 300

Error Codes

There are three error codes that may be shown on the user interface.

OtP: Screen toggles between OtP and ERR to indicate that the fixture has gone into over-temperature protection mode to avoid damaging the fixture. Once the fixture has self-cooled, the error will automatically clear.

CBL: Screen toggles between CBL and ERR to indicate that a control card or the internal cabling is damaged or unplugged.

No App: Screen toggles between no and APP to indicate that the upgraded fixtures have a software issue. Use UpdaterAtor software to reload software to clear the error.

If any of the above error codes persist, please contact RAYN Growing Systems at for additional troubleshooting assistance.
