Yeah, matter of fact I was thinking about that feature today so I'm glad that you mentioned it. We have the idiot light in the display that will likely never, ever come on. So, if we can design the gizmo so that the fan starts if/when the sensor fails high out of range... AND we can start the fan if the oil sensor wire ever gets unplugged/ripped in half by a stick or something...? Should we tie that over-temp LED into that half of the device, so that the idiot light comes on whenever the sensor fails high, or it gets unplugged?
We can take advantage of that light somewhere else besides an overheat condition I feel, because the primary function of the gizmo should already eliminate any overheating by its sensitivity and precision.
Of course, the oil cooler could get plugged up with mud or the cooling fan motor could fail or blow a fuse, causing an overheat. Unless we add a thermister onto the cooler to monitor cooler temps and add a hall-effect tachometer circuit to the fan motor... :-)
Think about it... lets bounce some ideas.
So far I think we are gonna have to monitor the ambient air temperature, because sub-zero air temps would false-trigger our sensor failing high feature. Complexities are imminent. :-)
Actually we might be able to turn that over-temp LED on if the motor overheated too, so don't rule that possibility out just yet.
