Calibration mode
Parameters in a mode can be
switched by the Display Key. 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.

■ How to Use the Error Display
When an error has occurred, the No.1 display alternately indicates error codes together with the current display item.
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.

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.
