Position-proportional Models Control output Assignment destination Alarm 3 type Alarm 3 open in alarm Direct/Reverse operation Output Assignments Signals available as allocated outputs are the control output (heat), control output (cool), alarm 1, alarm 2, alarm 3, LBA, and HBA. The auxiliary outputs of the Digital Controller cannot be used as control outputs. Control output (heat), control output (cool) , alarm 1, alarm 2, alarm 3, LBA, error 1 (input error), error 2 (A/D converter error), and error 3 (RSP input error) output functions are available. These functions are assigned to control outputs 1 and 2 and auxiliary outputs 1 and 2. The assignment destination of each output function is may be restricted. Refer to the following table. 1 2 Alarm 1 --- --- Yes Yes Alarm 2 --- --- Yes Yes Alarm 3 --- --- Yes Yes Error 1: Input error --- --- Yes Yes Error 2: A/D converter error --- --- Yes Yes Error 3: RSP input error --- --- Yes Yes Output function 1 2 Auxiliary output LBA The LBA (loop break alarm) function is available when it is assigned as an output. The LBA function is not available when a memory or A/D converter error results. LBA is a function for determining that an error has occurred somewhere on the control loop and outputting an alarm when the process value does not change with the manipulated variable at a maximum or minimum state. Accordingly, the LBA function can be used as a means for detecting a malfunctioning control loop. 11 E5AK E5AK Alarm Mode Selectors Alarm outputs are available if they are allocated as outputs.

The parameter following the last parameter is the top parameter. 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. 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. 13 E5AK E5AK 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, 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 7 for the setting in detail. 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 which the set point during SP ramp is limited is referred to as the "SP ramp." Level 0 Mode Process value PV/SV (local SP/remote SP) SP ramp Set point during SP ramp Set point For E5jK-PRR2 SP ramp set value MV monitor (heat) SP ramp time unit Valve opening monitor Manipulated variable Time Switching point (Heat/Cool) Manipulated variable MV monitor (cool) 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. 14 The change rate during the SP ramp is specified by the "SP ramp set value" and "SP ramp time unit" parameters. At the "SP ramp set value" default "0," the SP ramp function is disabled. The set point changing in SP ramp can be monitored in the "Set point during SP ramp" parameter (level 0 mode).

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 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). * * Operation When less than "-1999" When greater than "9999" Control continues, allowing normal operation. 19 E5AK E5AK 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 20 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. E5AK E5AK Fuzzy Self-tuning Fuzzy self-tuning is a function that enables the E5AK/E5EK to calculate the most suitable PID constants for the controlled object. Features * The E5AK/E5EK determines by itself when to perform fuzzy self-tuning. Fuzzy Self-tuning Function The fuzzy self-tuning function has three modes. 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. Startup Conditions of SRT SRT will start if the following conditions are satisfied simultaneously when the E5AK/E5EK is turned on or the set point is changed. At the time the E5AK/E5EK starts operating At the time set point is changed 1. The set point at the time the E5AK/E5EK starts operating is different from the set point used at the time SRT was last executed (see note). 2. The process value at the time the E5AK/E5EK starts operating is smaller than the set point in reverse operation and larger than the set point in normal operation. 1. The new set point is different from the set point used at the time SRT was last executed (see note). 2. 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. 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. 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. Temperature Slope (R) Stable range SP 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 Stable range Set point Stable range (Set to 15.0_C before shipping) Stability judgement time 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 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. Extreme value 2 Set point change Temperature SP Extreme value 1 Time 21 E5AK E5AK Startup Conditions of HT HT will be ON when there is hunting with four or more maximum temperature values (extreme values) while SRT is not being executed. Extreme value 2 Note: In specific applications where temperature varies periodically due to disturbance, internal parameters need to be adjusted. For details, refer to the E5AK/E5EK User's Manual (H83/H85).

Keep within the rated ambient operating temperature, ambient operating humidity, and storage temperature ranges. Use the Unit according to the vibration resistance, shock resistance, and enclosure ratings. Do not use the Unit in places with corrosive gas or excessive dust. Do not use the Unit nearby machines generating high-frequency noise. Correct Use Mounting The dimensions of the Digital Controller conform to DIN 43700. Recommended panel thickness is 1 to 8 mm. Mount the Unit horizontally. Connection To reduce inductive noise influence, the lead wires connecting the input type to the Digital Controller must be separated from the power lines and load lines. Use the specified compensating conductors for thermocouples. Use lead wires having a small resistance for platinum resistance thermometers. Connection Example Wire the terminals of the Unit using solderless terminals. The tightening torque applied to the terminal screws of the Unit must be approximately 0.78 N S m or 8 kgf S cm. 32 7.2 mm max. 7.2 mm max. Operation The alarm outputs of a model with an alarm function may not turn ON properly when the model malfunctions. The use of alarm equipment with the model is recommended. The parameters and internal switch are set before shipping so that the Unit will function normally. Change the settings of the parameters and internal switch according to the application if necessary. Several seconds are required until the relay is turned ON after power has been supplied to the Digital Controller. Therefore, take this time delay into consideration when designing sequenced circuits which incorporate a Digital Controller. Do not use excessive force when drawing out the internal mechanism from the housing. Protect the internal connector or electronic parts of the Unit from shock. Protect against static discharge when changing the settings of the internal switch. Changing the settings on a grounded conductive mat is recommended. When connecting the Control Output Unit to the Temperature Controller or Digital Controller, make sure that the Control Output Unit is a suitable type. The use of an improper type of Control Output Unit may cause the system to malfunction. The heater burnout alarm will not be available if the Linear Output Unit is used.
