TC1 controls the PILOT temperature TC2 controls the Detonation Arrestor TC3 controls the SHROUD temperature This manual addresses the details of the TC3 SHROUD Temperature Controller. SAFETY FIRST The fuel supply feed of the Shroud is interlocked to the Pilot as a safety fature. In operation, the shroud burner will not be fed fuel unless the pilot is fully operational and running, because TC3 gets its operating voltage from the Pilot status. No pilot, no fuel to the shroud burner. TC3 controls the fuel feed valve to the shroud and is designed as a fail safe control. The valve is a ballstyle, fail close configuration, which will automatically close to the shutoff position with the loss of air (motive power) or loop current (control signal). Additionally, Fuel will be blocked in if the loop wiring is damaged or broken, or if power is lost. SHORT NARRATIVE The loop current signal is generated by TC3, and comprises a 4to20 mA electrical current, responsive to the target operating temperature. TC3 starts with a 20 mA control signal (valve full open) and decreases linerally to 4 mA (valve closing) as the operating temperature approaches the set point. When the temperature reaches the set point, the TC3 will hold the signal at 4 mA again to close the valve and stop the fuel. The system will thereafter throttle the valve to maintain the temperature at the SV setting on the display. This setpoint is always visible in the TC3 display, and can be adjusted with momentary contact keys: THE SYSTEM IS DESIGNED TO RUN IN AN UNATTENDED MODE S A L E S and S E R V I C E SUPPORT Copyright© 2020 JRS Page 1 8/27/2020 Summary Narrative, continued. The Shroud Burner uses a temperature controller which employs "Fuzzy Logic". Because of the thermal response of the operating environment, this type of logic can selfadapt to the leading or lagging response to PV disturbances, which helps stabilize the control. The TC3 temperature controller is technically classified as a useradjustable microcontroller because so many of the operating parameters are userselectable. Shown below are displays at when operating and when cooled down. The running temperature is 1486 Deg.F in the upper (Red)
