    Chapter 1 Overview Chapter 1 Overview 1-1 General 1-1 General The Fuzzy Logic plus PID microprocessor-based controller series, incorporate a bright, easy to read 4-digit LED display, indicating process value or set point value. The Fuzzy Logic technology enables a process to reach a predetermined set point in the shortest time, with the minimum of overshoot during power-up or external load disturbance.
  • Page 6 PID control with properly tuned PID + Fuzzy control Temperature point Figure 1.1 Figure 1.1 Fuzzy Control Fuzzy Control Advantage Advantage Load Disturbance Warm Up Time High Accuracy High Accuracy The series are manufactured with custom designed ASIC(Application Specific Integrated Circuit ) technology which contains a 18-bit A to D converter for high resolution measurement ( true 0.1 BF resolution for thermocouple and PT100 ) and a 15-bit D to A converter for linear current or voltage control output.
  • Page 7 Auto-tune Auto-tune The auto-tune function allows the user to simplify initial setup for a new system. A clever algorithm is provided 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 as the process has been in steady state ( warm start ).

    Output 2 can be selected as alarm output. There are 6 types of alarm functions and one dwell timer can be selected, and four kinds of alarm modes ( ALMD ) are available for each alarm function. A process alarm sets two absolute trigger levels. When the process is process alarm sets two absolute trigger levels.

    Output 2 can be configured as dwell timer by selecting TIMR for OUT2. As the dwell timer is configured, the parameter SP2 is used for dwell time adjustment. The dwell time is measured in minutes ranging from 0.1 to 4553.6 minutes. Once the process reaches the setpoint the dwell timer starts to time down to zero ( time out ).

    In certain application the process value is too unstable to be read. To improve this a programmable low pass filter incorporated in the controller can be used. This is a first order filter with time constant specified by parameter . The default value of FILT is 0.5 sec. before shipping.

  • Page 40: Failure Transfer

    The controller will enter as one of the following conditions occurs: occurs due to the input sensor break or input current below 1mA if 4-20 mA is selected or input voltage below 0.25V if 1-5 V is selected . occurs due to the A-D converter of the controller fails. The output 1 and output 2 will perform the function as the controller enters failure mode.

    1. The system has been installed normally. 2. Set the correct values for the setup menu of the unit. But don't use a zero value for PB and TI, otherwise, the auto-tuning program will be disabled. The LOCK parameter should be set at NONE. 3.

  • Page 42: Manual Tuning

    The auto-tuning can be applied either as the process is warming up ( Cold Start ) or as the process has been in steady state ( Warm Start ). After the auto-tuning procedures are completed, the display will stop flashing and the unit will revert to PID control, using he new PID values.
