To prevent accidents arising from the use of this controller, please ensure the operator using it receives this manual. 1

2 NOTES TO USERS ***** Note to users ***** Before operating this controller, make sure you have understood the following. Warning Turn the power supply to the instrument OFF before wiring or checking. Working or touching the terminal with the power switched ON may result in an Electric Shock which could cause severe injury or death. Moreover, the instrument must be grounded before the power supply to the instrument is turned on. Caution Do not apply a commercial power source to the sensor connected to the input terminal nor allow the power source to come into contact with the sensor, as the input circuit may be burnt out. This instrument should be used according to the specifications described in the manual. If it is used outside the specifications, it may malfunction or cause fire. Be sure to follow the warnings, cautions and notices. If not, it could cause serious injury or malfunction. Specifications of the FCS-1A and the contents of this instruction manual are subject to change without notice. Care has been taken to assure that the contents of this instruction manual are correct, but if there are any doubts, mistakes or questions, please inform our sales department. Be sure to turn the power supplied to the instrunment OFF when cleaning. Wipe the instrument using dry soft cloth. (If the paint thinner is used for wiping, the instrument may be deformed or discolored.) The display parts are more easily damaged. Do not strike them with hard objects or press hard on them. Any unauthorized transfer or copying of this document, in part or in whole, is prohibited. Shinko Technos is not responsible for any damages or secondary damages incurred as a result of using this product, including any indirect damages. Setup by the DIP switch and the rotary switch inside of the controller is required before the power is turned on. The product is factory adjusted as [Sensor input: K, Control action: Fuzzy self-tuning PID, Heating action, Alarm (A1): No alarm action, no standby function, Unit: and Program starting form: manual]. Refer to Chapter. Setup (page 9). It is recommended that the PID auto-tuning be performed on the trial run. It is advised to provide the protective device against such environmental conditions which may cause damage to the device or contribute to the deterioration of its parts. 2

40 CONTROL ACTIONS 8. Control actions 8.1 Fuzzy self-tuning Fuzzy self-tuning is a function to perform a fine adjustment of PID values automatically. The stable control can be carried out even if the conditions of the process are changed due to things like change in types and rates of production. (1) When the control is rising, the controller performs the control by the PID values tuned in advance. (2) When the control result is disordered by the disturbance or a change in the process, the controller checks the converging status, and performs a fine adjustment of PID values if necessary. (a) If the convergence is performed smoothly, the PID values are not changed. (b) If the convergent speed is slow, the controller corrects the PID values to accelerate the convergence. (c) When overshoot is generated during the convergence, the controller corrects the PID values so as not to generate the overshoot. (d) When hunting is generated, the controller checks the waveform and performs fine adjustment of PID values. () The controller can be used without Fuzzy self-tuning by designating the internal switch. () When using the controller for the first time, perform the PID auto-tuning or set the proper PID values by key operation. The instrument is always in self-tuning status itself, and when deviation is created, it starts the tuning. Even if in Fuzzy self-tuning status, when very large hunting is caused and the control is not stabilized, it starts auto-tuning automatically. When the auto-tuning performance is designated by the key operation, tuning is initiated, and when the control is stabilized, the auto-tuning is released and returns to self-tuning status. When lock mode [ ] or [ ] is designated, Fuzzy self-tuning or Auto-tuning PID action cannot work. With the control system in which load fluctuation periodically occurs, the Fuzzy self-tuning may fall into malfunction. In such a case, use the controller with the PID auto-tuning mode. 0

41 CONTROL ACTIONS 8.2 Explanations of PID (1) Proportional band (P) Proportional action is the action which the control output varies in proportion to the deviation between the setting value and the processing temperature. If the proportional band is narrowed, even if the output changes by a slight variation of the processing temperature, better control results can be obtained as the offset decreases. However, if the proportional band is narrowed too much, even slight disturbances may cause variation in the processing temperature, and control action changes to ON/OFF action and the so called hunting phenomenon occurs. Therefore, when the processing temperature comes to the balanced position near the setting value and a constant temperature is maintained, the most suitable value is selected by gradually narrowing the proportional band while observing the control results. (2) Integral time (I) Integral action is used to eliminate offset. When the integral time is shortened, the returning speed to the setting point is quickened. However, the cycle of oscillation is also quickened and the control becomes unstable. () Derivative time (D) Derivative action is used to restore the change in the processing temperature according to the rate of change. It reduces the amplitude of overshoot and undershoot width. If the derivative time is shortened, restoring value becomes small, and if the derivative time is made longer, an excessive returning phenomenon may occur and the control system may be oscillated. 1

42 CONTROL ACTIONS 8. PID auto-tuning of this controller In order to set each value of P, I, D and ARW automatically, the auto-tuning process should be made to fluctuate to obtain an optimal value. (1) When the difference between setting value and processing temperature is large when the temperature rises. The AT process will fluctuate at the temperature 1.5% of scaling span lower than the setting value. Setting value 1.5% of scaling span Temperature Controlling action is performed with the values set by PID auto-tuning. Time [Figure 8.-1] (2) When the control is stable or when control temperature is within ±1.5% of scaling span. The AT process will fluctuate around the setting value. Starting point of auto-tuning Setting value Temperature Controlling action is performed with the values set by PID auto-tuning. Time [Figure 8.-2] () When the control temperature is 1.5% or greater of scaling span higher than the setting value. The AT process will fluctuate at the temperature 1.5% of scaling span higher than the setting value. 1.5% of scaling span Setting value Temperature Controlling action is performed with the values set by PID auto-tuning.
