PRECAUTIONS ON SAFETY
Marks For Ensuring Safe Use and Their Meanings
This manual uses the following marks to indicate precautions for ensuring that the
E5CKĆT is used safely.
The precautions indicated below describe important information regarding safety. Be
sure to follow the instructions described in these precautions.
WARNING
Incorrect handling may cause death or injury.
WARNING
Do not touch the terminals while the power is
ON.
This may cause an electric shock.
IV
NOTICE
Be sure to observe these precautions to ensure safe use.
Do not use the product in places where explosive or flammable gases may be present.
Never disassemble, repair or modify the product.
Tighten the terminal screws properly.
Use the specified size of solderless terminals for wiring.
Use the product within the rated supply voltage.
Use the product within the rated load.
The life expectancy of the output relay varies considerably according to its switching capacity and
operating conditions. Be sure to use the output relay within its rated load and electrical life expecĆ
tomcy. If the output relay is used beyond its life expectancy, its contacts may become fused or burned.
If you remove the controller from its case, never touch nor apply shock to the electronic parts inside.
Do not cover the E5CKĆT. (Ensure sufficient space around the controller to allow heat radiation.)
Do not use the controller in the following places:
Ă• Places subject to icing, condensation, dust, corrosive gas (especially sulfide gas or ammonia gas).
Ă• Places subject vibration and large shocks.
Ă• Places subject to splashing liquid or oil atmosphere.
Ă• Places subject to intense temperature changes.
Ă• Places subject to heat radiation from a furnace.
Be sure to wire properly with correct polarity of terminals.
When wiring input or output lines to your controller, keep the following points in mind to reduce the
influence from inductive noise:
Ă• Allow adequate space between the high voltage/current power lines and the input/output lines.
Ă• Avoid parallel or common wiring with high voltage sources and power lines carrying large currents.
Ă• Using separating pipes, ducts, and shielded line is also useful in protecting the controller, and its
lines from inductive noise.
Cleaning: Do not use paint thinner or organic solvents. Use standard grade alcohol to clean the prodĆ
uct.
Use a voltage (100 to 240 VAC at 50 to 60 Hz). At power ON, the prescribed voltage level must be
attained within two seconds.
Allow as much space as possible between the controller and devices that generate a powerful high
frequency (highĆfrequency welders, highĆfrequency sewing machines, etc.) or surge. These devices
may cause malfunctions.
If there is a large powerĆgenerating peripheral device and any of its lines near the controller, attach
a surge suppressor or noise filter to the device to stop the noise affecting the controller system. In
particular, motors, transformers, solenoids and magnetic coils have an inductance component, and
therefore can generate very strong noise.
When mounting a noise filter on the power supply to the controller, be sure to first check the filter's
voltage and current capacity, and then mount the filter as close as possible to the controller.
V
Use within the following temperature and humidity ranges:
Ă• Temperature: Ć10C to 55C, humidity: 35%RH to 85%RH (with no icing or condensation)
If the controller is installed inside a control board, the ambient temperature must be kept to under
55C, including the temperature around the controller.
If the controller is subjected to heat radiation, use a fan to cool the surface of the controller to under
55C.
Store within the following temperature and humidity ranges:
Ă• Temperature: Ć25C to 65C, humidity: 35%RH to 85%RH (with no icing or condensation)
Never place heavy objects on, or apply pressure to the controller that may cause it to deform and deteĆ
riorate during use or storage.
Avoid using the controller in places near a radio, television set, or wireless installation. These devices
can cause radio disturbances which adversely affect the performance of the controller.

CHAPTER 1 INTRODUCTION
JOutput
F Output assign-
ments
F Transfer output
The output functions of the E5CKĆT do not operate for five seconds after the
E5CKĆT is turned ON.
The E5CKĆT supports the following five outputs:
Control output 1
Control output 2
Auxiliary output 1
Transfer output
When using control output 1 and 2, set the output unit (sold separately).
Nine output units are available to suit the output circuit configration.
When using transfer output, add on the communication unit (E53ĆAKF).
Ă• The E5CK-T supports the following twelve output functions:
Control output (heat), Control output (cool), Alarms 1 to 3, LBA,
Time Signals 1 and 2, Program End, Stage Output,
Error 1 (input error), Error 2 (A/D converter error)
Ă• Assign these output functions to control output 1, control output 2 and
auxiliary output 1.
Ă• Only control output (heat), control output (cool), alarms 1 to 3 and LBA
can be assigned to control outputs 1 and 2. Only alarms 1 to 3, LBA, error
1 and error 2 can be assigned to auxiliary output 1.
In the example on the previous page, control output (heat)" is assigned
to "control output 1", "alarm 1" is assigned to "control output 2", and
"alarm 2" is assigned to "auxiliary output 1". Accordingly, the configuĆ
ration is such that heating control output is connected to control output
1, and alarm output is connected to control output 2 and auxiliary outĆ
put 1.
Ă• When the control is heating and cooling control, assign "control output
(cool)" to "control output 1" or "control output 2".
Ă• The E5AK-T supports the following four transfer outputs:
Present SP, Process value, Heating side manipulated variable,
Cooling side manipulated variable
Ă• These transfer outputs can be output after being scaled. Setting of an upĆ
per limit value smaller than the lower limit value is allowed, so reverse
scaling can also be carried out.

1.3 Program
JHow programs
are structured
E5CK-T allows you to configure programs made up of a maximum of four
patterns (pattern 0 to 3) each comprising a maximum of 16 steps.
The number of patterns and steps in each pattern can be specified in paĆ
rameters.
Pattern 3
Pattern 1
Pattern 0
Step 0 Step 1 Step 2 Step 15
Ă• Generally, the time setup method" is used to configure programs. By
this method, set points at each step and time are used as program eleĆ
ments. However, the ramp rise rate setup method" can also be used. By
this method, the set point, ramp time and soak times are used as program
elements.
JProgram opera-
tion
F Step operation
JAlarm output
JProgram output
Ă• Generally, the target patterns are specified before the program is
executed.
Ă• In parameter setup, you can specify repeated execution of the same patĆ
tern (Repeat) or consecutive execution of all patterns 0 to 4 (Run all).
Ă• During program operation, steps can be skipped (Advance) and the conĆ
trol monitoring can be paused (Hold).

1.4 Parameters and Menus
JParameter types
F Protect mode
F Manual mode
E5CKĆT parameters are distributed between the following ten modes:
Protect mode
Manual mode
Level 0 mode
Program mode
Level 1 mode
Level 2 mode
Setup mode
Expansion mode
Option mode
Calibration mode
The settings of parameters in each of eight modes (excluding the protect
mode and manual mode) can be checked and modified by selection on the
menu display.
The protect function is for preventing unwanted modification of parameĆ
ters, and switching between run and reset operation or auto and manual
operation.
In this mode, the controller can be switched to manual operation. The maĆ
nipulated variable can be manipulated manually only in this mode.
F Level 0 mode
F Program mode
F Level 1 mode
F Level 2 mode
F Setup mode
Set the controller to this mode during normal operation. In this mode, you
can change the set point and pattern during operation, and execute step
operation (e.g. advance). You can only monitor (not change) the process
value, step No., standby time, pattern elapsing time, pattern execution
count and manipulated variable.
This is the programming mode. In this mode, you can set the number of
steps used in each pattern, pattern execution count, alarm values, set
points for each step, step time, and time signals for two steps.
This is the main mode for adjusting control. In this mode, you can execute
AT (autoĆtuning), and set up the control period, PID parameters.
This is the auxiliary mode for adjusting control. In this mode, you can set
the parameters for limiting the manipulated variable, switch between the
remote and local modes, and set the loop break alarm (LBA), alarm hysterĆ
esis and the digital filter value of inputs.
This is the mode for setting the basic specifications. In this mode, you can
set parameters that must be checked or set before operation such as the
input type, scaling, output assignments and direct/reverse operation.

JSelecting modes
This is the mode for setting expanded functions. In this mode, you can set
SP setting limitter, switching between advanced PID control or ON/OFF
control, program time unit, selection of step time/rate of rise programĆ
ming, time unit of ramp rise rate, and the time for automatic return to the
monitoring display.
This is the mode for setting optional functions. You can select this mode
only when an option unit is mounted in the controller. In this mode, you
can set the communications conditions, transfer output and event input
parameters to match the type of option unit mount in the controller.
This mode is provided so that the user can calibrate inputs and output.
When calibrating input, the selected input type is calibrated. Whereas,
transfer output can be calibrated only when the communication unit
(E53ĆCKF) is set in the controller.

1.5 About the Communications Function
1.5 About the Communications Function
The E5CKĆT can be provided with a communications function that allows
you to check and set controller parameters from a host computer. If the
communications function is required, add on the communications unit.
For details on the communications function, refer to Chapter 6.
F RS-232C
F RS-485
When using the communications function on the RSĆ232C interface, add
on the communications unit (E53ĆCK01).
When using the communications function on the RSĆ485 interface, add on
the communications unit (E53ĆCK03).

CHAPTER 1 INTRODUCTION
1.6 About Calibration
The E5CKĆT controller is calibrated before shipment from the factory. So,
the user need not calibrate the E5CKĆT controller during regular use.
However, if the E5CKĆT controller must be calibrated by the user, use the
parameters provided for the user to calibrate temperature input, analog
input (voltage, current) and transfer output. In this case, note that the reĆ
sults of calibration will not be assured.
Also, note that calibration data is updated to the latest value each time
that the E5CKĆT controller is calibrated. Calibration data set before shipĆ
ment from the factory cannot be returned to after calibration by the user.
F Calibrating
inputs
F Calibrating trans-
fer output
F Registering cal-
ibration data
The input type selected in parameters is the item to be calibrated. The
E5CKĆT is provided with the following four calibration parameters:
Ă• Thermocouple
Ă• Platinum resistance thermometer
Ă• Current input
Ă• Voltage input
Two parameters are provided for thermocouple and voltage input.
Transfer output also can be calibrated when the communications unit
(E53ĆCKF) is added on.
When calibrating each item, the calibration data is temporarily regisĆ
tered. This data can be registered as final calibration data only when all
items have been newly calibrated. So, all items must be temporarily regisĆ
tered when the E5CKĆT controller is calibrated.
When registering data, information regarding whether or not calibration
has been carried out is also registered.
To calibrate these items, the user must prepare separate measuring deĆ
vices and equipment. For details on handling these measuring devices and
equipment, refer to the respective manuals.

Ă• The scaling upper limit", scaling lower limit" and decimal point" paĆ
rameters (setup mode) are used for scaling. These parameters cannot be
used when the temperature input type is selected.
Ă• The scaling upper limit" parameter sets the physical quantity to be exĆ
pressed by the upper limit value of input, and the scaling lower limit"
parameter sets the physical quantity to be expressed by the lower limit
value of input. The decimal point" parameter sets the number of digits
past the decimal point.

With control output (cool), the conditions for switching from standard control
to heating and cooling control are reached when the output function is assigned
at the cooling side during heating and cooling control.
In other words, heating and cooling control is carried out when control
output (cool) is assigned, and standard control is carried out when outĆ
put is not assigned. For details on heating and cooling control, see ChapĆ
ter 4 Applied Operation/4.1 Selecting the Control Method (page 4Ć2).
Ă• Factory settings are as follows:

JDirect/reverse
operation
Ă• Direct operation" (or normal operation) refers to control where the maĆ
nipulated variable is increased according to the increase in the process valĆ
ue. Alternatively, reverse operation" refers to control where the manipuĆ
lated variable is decreased according to the decrease in the process value.
For example, when the process value (PV) (temperature), is lower than
the set point (SP) (temperature), in a heating control system, the manipĆ
ulated variable increases by the difference between the PV and SP valĆ
ues.
Accordingly, this becomes reverse operation" in a heating control sysĆ
tem, or alternatively, direct operation" in a cooling control system.
Ă• Direct/reverse operation is set in the direct/reverse operation" parameĆ
ter (setup mode). The direct/reverse operation" parameter is factoryĆ
set to

Ă• Standby sequence" is a function for unconditionally turning alarm outĆ
put OFF when the process value has left the alarm range once and it next
enters the alarm range.
Ă• For example, when the alarm type is set to lowerĆlimit alarm," generalĆ
ly the process value is within the alarm range, and alarm output smaller
than the set point, and alarm output becomes ON when this state continĆ
ues. However, if the alarm type is set to lowerĆlimit alarm with standby
sequence", alarm output first becomes ON when the process value exĆ
ceeds the alarm setting value to leave the alarm range and once again
falls below the alarm value.
Ă• The standby sequence is canceled when an alarm is output. It is, howevĆ
er, restarted later by one of the following conditions:
Operation is started or power is turned ON.
A pattern is started.
The program advances to the next step.
The SP of the current step is changed.

About PID Parameters
AT Execution Timing
When control characteristics are already known, the PID parameters can be set diĆ
rectly to adjust control.
PID parameters are set in the proportional band" (P), integrated time" (I) and
derivative time" (D) parameters (level 1 mode).
For details on the setting ranges of these parameters, see chapter 5 Level 1 Mode
(page 5Ć17).
The E5CKĆT differs from fixedĆvalue type controllers in that the SP changes autoĆ
matically. So, the timing of AT execution is the most important factor in control.
To obtain PID parameters for a specific SP, make a fixedĆvalue program as follows
and execute AT.

Ă• For details on how to assign outputs, see 3.3 Setting Output SpecificaĆ
tions (page 3Ć7).
Ă• When heating and cooling control is selected, the dead band" and coolĆ
ing coefficient" parameters can be used.
F Dead band
The dead band is set with the set point as its center. The dead band width
is the set value of the dead band" parameter (level 1 mode). Setting a posiĆ
tive value produces a dead band, while setting a negative value produces
an overlap band.
The dead band is factoryĆset to 0.00:0.00%FS."

using the cooling coefficient to balance control between the heating and
cooling sides. In heating and cooling control, P at the heating or cooling
side is calculated by the following formula:
Heating side P = P; Cooling side P = cooling coefficient P

4.1 Selecting the Control Method
F Manipulated vari-
able at reset
Ă• In heating and cooling control, the manipulated variable output that is
output when controller operation is stopped is dependent on the set valĆ
ue of the MV at reset" parameter (level 2 mode) in the same way as for
standard control.
Ă• However, note that in heating and cooling control, the manipulated variĆ
able at the cooling side is treated as a negative value for the sake of conveĆ
nience. When the manipulated variable at reset is a negative value, the
manipulated variable is output to only the cooling side, and when a posiĆ
tive value, the manipulated variable is output to only the heating side.
Default is 0". If the controller is operated with default, the manipulated
variable is not output to both the heating and cooling sides.

When the overlap band is set, the bumpless function that operates when switching
between manual and automatic operation may not work.

ried out by the PID/ON/OFF" parameter (expansion mode). When this
parameter is set to [ĂĂĂ

set to [ ], ON/OFF control is selected. Default is [ĂĂĂ ].
Ă• In ON/OFF control, hysteresis is provided in the program when switchĆ
ing between ON and OFF to stabilize operation. The hysteresis width
provided during ON/OFF control is simply referred to as hysteresis."
Control output (heat) and control output (cool) functions are set in the

The upperĆ and lowerĆlimit values of the manipulated variable can be reĆ

The upperĆ and lowerĆlimit values of the manipulated variable are set in
the MV upper limit" and MV lower limit" parameters (level 2 mode).
When the manipulated variable calculated by the E5CKĆT is outside of the

4.3 Ramp Rise Rate Setup Program
4.3 Ramp Rise Rate Setup Program
Chapter 3 described programs that used the time setup method." ProĆ
grams were executed using a combination of SPs and step time values. The
E5CKĆT also supports the ramp rise rate setup method." By this method,
programs are executed using three program elements: target SP", rate
of rise" and soak time."
To select a ramp rise rate program, set the Step time/rate of rise programĆ
ming" parameter (expansion mode) to
Target SP
: rate of rise."
Soak time
Rate of rise
Time unit of ramp rate

Set each of the above program elements in the target SP 0 to 7", rate of
rise 0 to 7" and soak time 0 to 7" parameters.
In a ramp rise rate program, parameters are set to two steps as shown in
the figure above. The following figure shows the relationship between the
program and parameters.

CHAPTER 4 APPLIED OPERATION
F Relationship with
the number of
steps
F When the rate of
rise is set to “0”
When the number of steps is set to an odd number, the final soak time canĆ
not be set. For example, if we set the number of steps" parameter to 7",
the soak time 3" parameter cannot be set even though the target SP 3"
and rate of rise 3" parameters can be set.
Accordingly, when the number of steps are set to an even number, the final
step is a soak step. When it is set to an odd number, the final step is a ramp
step.
Number of steps = even number Number of steps = odd number
When rate of rise 0 to 7" parameter are set to 0", the ramp step is skipped
and the soak step appears to be continuous.
Step N is skipped.

F Changing
parameters
Step
Ramp rise rate setup programs take the PV at start of program operation
as the SP (PV start) when they are started.
When the rate of rise is changed midway during operation, the SP rate of
rise and the step time in the ramp cycle both change.

Ă• In the above figure, increasing the rate of rise results in a shorter target
step time. Likewise, when the SP is changed, the step time of the ramp
cycle also changes.
Ă• When the soak time is changed, only the step time in the soak cycle
changes.
4.3 Ramp Rise Rate Setup Program
JProgram example

Let's describe a typical example of a ramp rise rate setup program. In an
actual program, set the parameters to match the application.

Step 0 Step 1 Step 2 Step 3
30 60 90 120
Target SP 0 : 100

“Number of steps” = 4, “Time unit of ramp rate” = minutes, “PV start” = 10
Target SP 1 : 10
Rate of rise 1 : 3
Soak time 1 : 0.30
In a program comprising four steps, steps 0 and 1 follow the settings of the
target SP 0", rate of rise 0" and soak time 0" parameters. Steps 2 and
3 follow the settings of the target SP 1", rate of rise 1" and soak time
1" parameters.
F How the program
works
Parameters
(1) As the program starts at PV (PV start), the program starts operation
from 10" in this example.
(2) As the rate of rise is set to 3", the Present SP takes 30 minutes
(100Ć10/3=30) to reach the target SP value 100" in step 0. If the PV
is 40" when the program is started, this time then becomes 20 minĆ
utes using the same formula.
(3) In step 1, the Present SP does not change, and the step time is the valĆ
ue set to the soak time 0" parameter (in this example, 30 minutes").
(4) In step2, the Present SP changes according to the value of rate of rise
1" parameter from that of target SP 0" parameter to that of target
SP 1" parameter It takes 30 minutes in this example.
(5) In step 3, the Present SP does not change, and the step time is the valĆ
ue set to the soak time 1" parameter (in this example, 30 minutes").

Also, the LBA function does not work when a memory error or A/D conĆ
verter error results.
Ă• LBA (Loop Break Alarm) is a function for judging that an error has ocĆ
curred somewhere on the control loop and for 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.

F LBA detection
example
Ă• Normally, when output is set to maximum or minimum, the process valĆ
ue rises or falls after the dead time has elapsed. LBA is output if the proĆ
cess value does not change in the predicted direction after a fixed amount
of time has elapsed. This fixed amount of time is the LBA detection
time."
Ă• LBA operation sometimes becomes unstable when the process value
fluctuates considerably due to the control characteristics. The LBA
detection width is provided so that changes with respect to output can
be correctly detected. Changes smaller than the detection width due to
LBA detection timing are not regarded as changes.
Ă• The following example describes what happens when a heater burnout
occurs at maximum output.

Time
Heater burnout
Ă• LBA judgment is carried out at each LBA detection time from the point
of maximum output. In the above figure, the process value (PV) is changĆ
ing greatly at the 1st judgment time band, so LBA remains OFF.
Ă• At the 2nd judgment time band, the process value increases as indicated
by the broken line if the process value is normal. This means that the
change width exceeds the LBA detection width, and LBA output remains
OFF.
Ă• If the heater burns out at the point shown in the above figure, the process
value decreases." Accordingly, it is judged that the process value is not
changing in the increasing direction" at the 2nd judgment time band
and the LBA output becomes ON.
LBA=ON

CHAPTER 4 APPLIED OPERATION
F Setting the LBA
detection time
F Determining the
LBA detection
time
Ă• The LBA detection time is automatically set by autoĆtuning (except in
heating and cooling control).
Ă• If the optimum LBA detection time cannot be obtained by autoĆtuning,
set the time in the LBA detection time" parameter (level 2 mode).
Ă• Calculate the LBA detection time as follows:
(1) Set output to maximum.
(2) Measure the time it takes for the input change width to reach the LBA
detection width (factory setting: 0.2% FS).
Measurement time Tm

LBA detection time = Tm x 2
(3) Take a value twice that of the measurement time as the LBA detection

Transfer output Transfer output
Ă• You can select the following four data items in the transfer output type"
parameter (option mode) as the transfer outputs:
Present SP (default), Process value, Manipulated variable (heat),
Manipulated variable (cool).
Ă• If the output assignment is changed when either the manipulated variĆ
able (heat)" or manipulated variable (cool)" parameter is selected, the
factory setting set point" is returned to.
Ă• These transfer outputs can be scaled according to the settings of the
transfer output upper limit" and transfer output lower limit" paramĆ
eters before output. Setting of an upper limit value smaller than the lowĆ
er limit value is allowed, so reverse scaling can also be carried out. Also,
the scale can be enlarged by the upperĆ and lowerĆlimit width specified
for each data item. The following example shows scaling of the heating
