We designed the CTI Speed control to be the most robust, bullet proof motor controller available. The design of this oven control was a culmination of: design requirements, feedback from oven rebuilders and lessons learned from rebuilding over 500 controls. The CTI conveyor control cannot be damaged from failures of other oven components or even serious abuse (when wired properly). The control monitors for over current, ambient temperature, speed sensor problems, bad sensor wiring, failure of the user interface, locked motor rotor and even bad motor brushes. The CTI-M-DigSpd motor speed control has been in production for 15+ years. We feel this is the most robust oven control for pizza ovens in the market. The diagnostic capabilities aid in solving oven conveyor problems; no blind swapping and no guessing of the cause of the conveyor failure.The control was designed and is still built by our staff at Cybernetics Tech Industries. Our lead Engineer has over 30 years experience as an Engineer in both hardware and software (former Engineer for NASA Avionics research contracts).
