The parameter following the last parameter is the top parameter. ■ Parameters and Menus Protect Mode Limits use of the menu and A/M Keys. The protect function prevents unwanted modification of parameters and switching between the auto and manual operation. Manual Mode The Controller can be switched to manual operation. The manipulated variable can be manipulated manually only in this mode. Level 0 Mode Set the Controller to this mode during normal operation. In this mode, change the set point during operation, and start or stop Controller operation. The process value, SP ramp, and manipulated variable can only be monitored in this mode. Level 1 Mode The main mode for adjusting control. In this mode, execute AT (auto-tuning), and set alarm values, the control period, and PID parameters. Level 2 Mode The auxiliary mode for adjusting control. In this mode, set the parameters for limiting the manipulated variable and set point, switch between the remote and local modes, and set the loop break alarm (LBA), alarm hysteresis, and the digital filter value of inputs. Setup Mode The mode for setting the basic specifications. In this mode, set parameters that must be checked or set before operation such as the input type, scaling, output assignments and direct/reverse operation. Expansion Mode The mode for setting expanded functions. In this mode, set ST (self-tuning), SP setting limiter, select advanced PID or ON/OFF control, specify the standby sequence resetting method, initialize parameters, and set the time for automatic return to the monitoring display. Option Mode The mode for setting option functions. Select this mode only when the Option Unit is set in the Controller. In this mode, set the communications conditions, transfer output and event input parameters to match the type of Option Unit set in the Controller. Calibration Mode The mode for calibrating inputs and transfer output. When calibrating input, the selected input type is calibrated. Whereas, transfer output can be calibrated only when the Communications Unit (E53-CKF) is set in the Controller.

This section describes how to check error codes on the display, and the actions that must be taken to remedy the problem. Input Error Meaning Input is in error. Action Check the wiring of inputs, disconnections, and shorts, and check the input type and the input type jumper connector. Operation at Error For control output functions, output the manipulated variable matched to the setting of the “MV at PV error” parameter (level 2 mode). Alarm output functions are activated when the upper limit is exceeded. Memory Error Meaning Internal memory operation is in error Action First, turn the power OFF then back ON again. If the display remains the same, the E5CK Controller must be repaired. If the display is restored to normal, the probable cause may be external noise affecting the control system. Check for external noise. Operation at Error Control output functions turn OFF (2 mA max. at 4 to 20 mA output, and output equivalent to 0% in case of other outputs). Alarm output functions turn OFF. A/D Converter Error Meaning Internal circuits are in error. Action First, turn the power OFF then back ON again. If the display remains the same, the E5CK Controller must be repaired. If the display is restored to normal, the probable cause may be external noise affecting the control system. Check for external noise. Operation at Error Control output functions turn OFF (2 mA max. at 4 to 20 mA output, and output equivalent to 0% in case of other outputs). Alarm output functions turn OFF. Calibration Data Error Calibration data is in error. Action 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 Though not an error, this is displayed when the process value exceeds the display range when the control range (setting range ±10%) is larger than the display range (−1999 to 9999). • When less than “−1999” Operation • When greater than “9999” Control continues, allowing normal operation. Digital Controller E5CK I-81 Temperature Controller This error is output only during temperature input and is displayed for two seconds when the power is turned ON. Meaning ■ Fuzzy Self-tuning Fuzzy self-tuning is a function that enables the E5CK to calculate the most suitable PID constants for the controlled object. Features • The E5CK determines by itself when to perform fuzzy self-tuning. Fuzzy Self-tuning Function The fuzzy self-tuning function has three modes. 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 towards the suitable proportional band value, and the set point at that time will be the SRT-executed set point. Slope (R) 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 to suppress the hunting. Note: Be sure to turn on the power supply to 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 to 0% for a short period of time before being returned to 100%, and the constants will then be retuned. Retuning is performed only for large amounts of dead time, so be sure to follow the precaution given above when starting operation. Temperature Time Stable Temperature Status 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 to the characteristics of the object to be controlled. Fuzzy self-tuning will not be activated if the temperature is stable because the Temperature Controller deems that temperature control is smooth. Shorter than the stability judgement time Startup Conditions of SRT SRT will start if the following conditions are satisfied simultaneously when the E5CK is turned on or the set point is changed.

Note: The last SRT-executed set point is set to 0 before shipping and when changing from advanced PID control to advanced PID control with fuzzy self-tuning. Stable Stable Balanced Status If the process value is within the stable range for 60 s when there is no output, it is deemed that the temperature is balanced. Startup Conditions of DT 1. DT will start if the temperature that has been stable varies due to 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. 2. 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.
