***Correction***
On page three of the above instructions the paragraph starting with "The orange wire will provide..." should read. "The orange wire will provide a "press-to-test" or an "acknowledge" function depending on the fuel sense. lf the end-of fuel is being sensed, providing power to the orange wire serves as an "acknowledge" and clears the output until the UFS power is re-cycled. If fuel is being sensed, providing power to the orange wire provides a system press-to-test." Grounding the orange wire shouldn't cause any ill effects but it does not provide the PTT function as decribed. I will get this corrected in the actual document and have it posted soon.
