16 How Use the Error Display When an error has occurred, the No. display alternately indicates error codes gether with the current display item. This section describes how check error codes on the display, and the actions that must be taken remedy the problem. Input Error Meaning Action Input is in error. Check the wiring of inputs, disconnections, and shorts, and check the input type and the input type jumper connecr. Operation at Error For control output functions, output the manipulated variable matched the setting of the MV at PV error parameter (level mode). Alarm output functions are activated when the upper limit is exceeded. Memory Error Meaning Action Internal memory operation is in error First, turn the power then back again. If the display remains the same, the Controller must be repaired. If the display is resred normal, the probable cause may be external noise affecting the control system. Check for external noise. Operation at Error Control output functions turn ( ma max. at 4 ma output, and output equivalent % in case of other outputs). Alarm output functions turn. A/D Converter Error Meaning Action Internal circuits are in error. First, turn the power then back again. If the display remains the same, the Controller must be repaired. If the display is resred normal, the probable cause may be external noise affecting the control system. Check for external noise. Operation at Error Control output functions turn ( ma max. at 4 ma output, and output equivalent % in case of other outputs). Alarm output functions turn. Calibration Data Error This error is output only during temperature input and is displayed for two seconds when the power is turned. Meaning Action Calibration data is in error. Must repair. Operation at Error Both control output functions and alarm output functions are active. However, note that the readout accuracy is not assured. Display Range Over Meaning Operation Though not an error, this is displayed when the process value exceeds the display range when the control range (setting range ±%) is larger than the display range ( ). When less than 999 When greater than 9999 Control continues, allowing normal operation. 6

17 Fuzzy Self-tuning Fuzzy self-tuning is a function that enables the calculate the most suitable PID constants for the controlled object. Features The determines by itself when self-tuning. Fuzzy Self-tuning Function The fuzzy self-tuning function has three modes. perform fuzzy In SRT (step response tuning) mode, the PID constants are tuned using a step response method at the time the set point is changed. In DT (disturbance tuning) mode, the PID constants are amended so that the controlled temperature will be within the target range set in advance when there is external disturbance. In HT (hunting tuning) mode, when hunting occurs, the PID constants are amended suppress the hunting. Note: Be sure turn on the power supply the load either before or simultaneously with the start of Temperature Controller operation. Dead time will be measured from the time the Temperature Controller starts operating. If a load such as a heater is turned on after the Temperature Controller is turned on, dead time longer than the actual value will be measured and inappropriate PID constants will be obtained. If an extremely large amount of dead time is measured, the control amount will be set % for a short period of time before being returned %, and the constants will then be retuned. Retuning is performed only for large amounts of dead time, so be sure follow the precaution given above when starting operation. Startup Conditions of SRT SRT will start if the following conditions are satisfied simultaneously when the is turned on or the set point is changed. At the time the starts operating. The set point at the time the starts operating is different from the set point used at the time SRT was last executed (see note).. The process value at the time the starts operating is smaller than the set point in reverse operation and larger than the set point in normal operation. Note: At the time set point is changed. The new set point is different from the set point used at the time SRT was last executed (see note).. The process value is in stable condition before the set point is changed. 3. A larger set point value is set in reverse operation and a smaller set point is set in normal operation. The last SRT-executed set point is set before shipping and when changing from advanced PID control advanced PID control with fuzzy self-tuning. PID Constant Refreshing Conditions If the step control amount is applied before the maximum temperature slope (R) is obtained, SRT will not renew any PID constant. If the proportional band obtained from the R and L values that were measured before the imposition had been completed is larger than the present proportional band, the PID constants will be renewed because the measured value is in the direction wards the suitable proportional band value, and the set point at that time will be the SRT-executed set point. Temperature Slope (R) Stable Temperature Status Time Stable range If the temperature is within the stable range for a certain time, it is deemed that the temperature is stable. This time is called stability judgement time. Like PID constants, stability judgement time is adjusted with fuzzy self-tuning according the characteristics of the object be controlled. Fuzzy self-tuning will not be activated if the temperature is stable because the Temperature Controller deems that temperature control is smooth. Set point Balanced Stable Status Shorter than the stability judgement time Stability judgement time Stable Stable range Stable range (Set 5._C before shipping) If the process value is within the stable range for 6 s when there is no output, it is deemed that the the temperature is balanced. Startup Conditions of DT. DT will start if the temperature that has been stable varies due external disturbance and the deflection of the temperature exceeds the stable range, and then the temperature becomes stable, provided that the number of maximum temperature values is less than four.. DT will start if the set point is changed under the condition that SRT does not start and the temperature becomes stable, provided that the number of maximum temperature values is less than four. If there are four or more maximum temperature values, HT will start. Temperature Extreme value Set point change Extreme value Time

18 Startup Conditions of HT HT will be when there is hunting with four or more maximum temperature values (extreme values) while SRT is not being executed. Note: In specific applications where temperature varies periodically due disturbance, internal parameters need be adjusted. For details, refer the User s Manual.
