Operation
■Parameter Operation List
Switching to modes other than manual or protect mode is carried out using mode selection in the menu display.
The figure below shows all parameters in the order that they are displayed. Some parameters are not displayed depending on the protect mode
setting and conditions of use.
■Parameters and Menus
Note: For more details on the functions of each part and display contents, refer to the E5CK User’s Manual (H78).
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 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, 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.
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.
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 re-
paired. 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.
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 re-
paired. 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.
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.
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.

■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.
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 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-
tion.
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 inappropri-
ate 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 per-
formed 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 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.
PID Constant Refreshing Conditions
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
proportional band obtained from the R and L values that were mea-
sured 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.
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.
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, pro-
vided that the number of maximum temperature values is less
than four.
If there are four or more maximum temperature values, HT will
start.
At the time the E5CK starts
operating
At the time set point is
changed
1. The set point at the time the
E5CK starts operating is dif-
ferent from the set point used
at the time SRT was last exe-
cuted (see note).
2. The process value at the time
the E5CK 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 nor-
mal operation.
