AUTO TUNING TEMPERATURE CONTROLLER
Controller parameters are not locked out upon delivery to allow ease of set up for installation and startup. Controller is factory tested and set up to allow auto tuning to be accomplished. Auto tuning should only be done after all adjustments to burner and exhaust damper have been set to insure oven meets temperature capacities without nuisance shut downs.
1. Auto tuning may be accomplished by starting oven and setting desired set point needed for your process.
2. Depress AUTO TUNE , (allowing at least 100 F between desired set point) controller begins flashing, reverting from oven temperature to “Tune”
3. The UDC controller immediately starts controlling to the set point while it identifies the process. The tuning sequence will cycle the controller’s output two full cycles, above set point then below set point. 4. When Accutune is complete, the calculated tuning parameters are stored in their proper memory location in the controller, and the controller will control at the local set point using the newly calculated tuning constants.
5. To about Accutune and return to the last parameters simply press MAN- AUTO/RESET key to abort the Accutune process.
