Description/Explanation of Issue
The fan on your dimming engine is powered by 24VDC from the dimming engine. The dimming engine has a current sensing circuit built into it. If the fan is damaged and unable to run, that circuit can't sense the current—resulting in the Fan Fail error.
If the fan can function in another rack without errors, there may be an issue with your dimming engine. Please contact ETC Technical Services to set up a repair.
In some rare cases, a bad fan can also damage the dimming engine it's plugged into, so if you know you're going to be replacing both components, always replace the fan first.
