The ASIC technology provides improved operat- ing performance, low cost, enhanced reliability and higher com- ponent density. Auto-Tune The auto-tune function allows the user to simplify initial setup for a new system by automatically determining the optimum set of PID settings for the thermodynamic system. A unique algorithm is programmed into the microprocessor to obtain an optimal set of control parameters for the process, and it can be applied either as the process is warming up (cold start) or if the process has been in a steady state (warm start). Fuzzy Logic Control The function of Fuzzy Logic Control is to adjust the PID parame- ters from time to time in order to make the modulated output value more flexible and adaptive to various processes. The result is to enable a process to reach a predetermined setpoint in the shortest time, with the minimum of overshoot and undershoot during power-up or external load disturbances. Digital Filter A first-order low-pass digital filter with a programmable time constant is a standard function of the software developed for the TEC controllers. It is used to improve the stability of the process value, especially in electrically noisy environments. Lockout Protection According to the actual security requirements, one of four lockout levels can be selected to prevent the unit from being changed erroneously. None: No parameter is locked. Set: User data is accessible, but setup data is locked. User: All user and setup parameters are locked, except setpoint. All: All user and setup parameters are locked, including setpoint. Bumpless Transfer Bumpless transfer allows the controller to continue to control the process by using the last known good output percentage value if the temperature sensor should fail. Hence, the process transfers from feedback closed loop control to open loop control and the process can be kept running until the sensor can be replaced. Soft Start Ramp The ramping function is performed during power up as well as any time the setpoint is changed. It can be ramping up or ramping down. The process value will reach the setpoint with a predeter- mined constant rate of rise or fall. Digital Communications The units can be equipped with a RS-485 or RS-232 interface card to provide digital communications. By using only twisted pair wires, up to 247 controllers can be connected together via the RS-485 interface to a host computer. 3/16 DIN: TEC-7100, TEC-7400 1/4 DIN: TEC-4100, TEC-4300, TEC-4400 DIN Rail Mount: TEC-6400 TEC Family of Controllers — Common Design Features for the Models Listed
