Note: The control of the Digital Controller is reset when the Digital Controller is in setup, expansion, option, or calibration mode, in which case the control and auxiliary outputs are OFF. The reset condition will be canceled when the Digital Controller is in any mode other than the above. ■ Parameters and Menus Note: For more details on the functions of each part and display contents, refer to the E5AK/E5EK User’s Manual (H83/H85). All functions selected with the Digital Controller in setup or expansion mode or all optional functions of the Digital Controller may not be displayed. 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. Digital Controller E5AK/E5EK 23 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, ramp SP, 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 pe- riod, 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, switch between the SP mode, 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, 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. Heater burnout latch function, position-proportional travel time, and remote SP scaling parameter are also located in this mode. 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. ■ Parameter Operation Refer to the E5AK/E5EK User’s Manual (H83/H85) for each parameter and the calibration mode in detail. Refer to page 9 for the setting in detail. Level 0 Mode SP Ramp With the SP ramp function, the Controller operates according to the value (set point during SP ramp) limited by a change rate, instead of the changed set point when the set point is changed. The interval in Process value PV/SV (local SP/remote SP) which the set point during SP ramp is limited is referred to as the “SP ramp.” Set point during SP ramp SP ramp Set point For E5@K-PRR2 SP ramp set value MV monitor (heat) Valve opening Manipulated SP ramp time unit monitor variable Time Switching point (Heat/Cool) The change rate during the SP ramp is specified by the “SP ramp set MV monitor value” and “SP ramp time unit” parameters. At the “SP ramp set (cool) Manipulated value” default “0,” the SP ramp function is disabled. variable The set point changing in SP ramp can be monitored in the “Set point during SP ramp” parameter (level 0 mode). Run/Stop PV/SV The process value is displayed on the No.1 display and the set point is displayed on the No.2 display. When the multi-SP function is in use, the value of whichever is set, set point 0 or 1, is linked. Remote SP Monitor Monitors remote SP in the local SP mode. Set Point During SP Ramp Monitors the set point when the SP ramp function is used. 24 Digital Controller E5AK/E5EK Protect Mode Manual Mode 1 s min. Press twice for 1 s min.

This is because input is treated as the “temperature” as it is matched to the input type. However, note that the upper- and lower-limit values of the Input type sensor can be shifted. For example, if both the upper- and lower-limit values are shifted by 1.2°C, the process value (before shift) is regarded as 201.2°C after shift when input is 200°C before shift.

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 con- nector. Operation at Error For control output functions, output the manipulated variable matched to the setting of the “MV at PV error” param- eter (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 E5AK/E5EK 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 E5AK/E5EK 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 This error is output only during temperature input and is displayed for two seconds when the power is turned ON. Meaning 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”  When greater than “9999” Operation Control continues, allowing normal operation. Digital Controller E5AK/E5EK 29 Motor Calibration Error (Displayed on the No. 2 Display) Meaning Motor calibration has ended with an error. Action First, correctly connect the wiring for the potentiometer, open output, and close output. Execute the motor calibration again. Operation Procedure Operation at Error When motor calibration is executed, open output will operate and then close output will operate. However, as the value is incorrect, the result turns out to be an error. 30 Digital Controller E5AK/E5EK ■ Fuzzy Self-tuning Fuzzy self-tuning is a function that enables the E5AK/E5EK to calcu- PID Constant Refreshing Conditions late the most suitable PID constants for the controlled object. If the step control amount is applied before the maximum tempera- ture slope (R) is obtained, SRT will not renew any PID constant. If the Features proportional band obtained from the R and L values that were mea- sured before the imposition had been completed is larger than the  The E5AK/E5EK determines by itself when to perform fuzzy self- present proportional band, the PID constants will be renewed tuning. because the measured value is in the direction towards the suitable proportional band value, and the set point at that time will be the Fuzzy Self-tuning Function SRT-executed set point. The fuzzy self-tuning function has three modes. Slope (R) Temperature In SRT (step response tuning) mode, the PID constants are tuned Stable range using a step response method at the time the set point is SP 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 con- stants 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 opera- Time tion. Dead time will be measured from the time the Temperature Stable Temperature Status Controller starts operating.
