What was the duty cycle on the SS stopping and starting the fan?
Somewhere in the tech manual for them gives the sizes you should use, my theory is the SS was undersized.
It's something I feel Siemens should make more of a point of, but if the duty cycle is quite high, or if it's a large inertia load. They often recommend a SS a couple of sizes bigger than you would expect.
