Knowing little about wrangling electrons outside of programming and PLC's, what is an elegant solution to detecting a fan failure on a monitored circuit?
Mercedes, Audi etc. have a bulb detection system that measures resistance on the circuit to alert the driver of a burned bulb. Infinite resistance = warning light, and position of said bulb.
If an enclosed fan (plain-Jane 6" square, electronics cooling, 24VDC OR 120VAC are options) fails, I'd like to be able to have that as an input to a controller. The fan failure would be a burn-out like in the case of a bulb. Measure infinite resistance on the circuit? A method to measure current draw in real time and then program based on that input?
What's the sophisticated, elegant way of doing this?
