Pay Attention to the Following when Installing
this Controller
F If you remove the controller from its case, never touch nor apply shock to the electronic
parts inside.
F Do not cover the top and bottom of the controller. (Ensure sufficient space around the
controller to allow heat to escape.)
F Use a voltage (AC100Ć240V
scribed voltage level must be attained within two seconds.
F 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/outĆ
put lines.
Ă• Avoid parallel or common wiring with high voltage sources and power lines carrying
large currents.
Ă• Using separating pipes, duct, and shielded line is also useful in protecting the controller,
and its lines form inductive noise.
F Allow as much space as possible between the controller and devices that generate a powĆ
erful, high frequency (highĆfrequency welders, highĆfrequency sewing machines, and so
forth) or surge. These devices may cause malfunctions.
F If there is a large powerĆgenerating peripheral device and any of its lines, 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 noises.
F When mounting a noise filter, be sure to first check the filter's voltage and current
capacity, then mount the filter as close as possible to the controller.
F Do not use the controller in places where icing, condensation, dust, corrosive gas (espeĆ
cially sulfurized gas or ammonia gas), shock, vibration, splashing liquid, or oil atmoĆ
sphere occur. Also, avoid places where the controller can be subjected to intense heat
radiation (like from a furnace) or sudden temperature changes.
or AC/DC24V at 50 to 60 Hz). At power ON, the preĆ
IV
F Ambient temperature must be kept between Ć10_C to 55_C. Ambient humidity must be
kept between 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 under 55_C,
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 55_C.
F Store the controller at an ambient temperature between Ć25_C to 65_C. The ambient
humidity must be between 35%RH to 85%RH (with no icing or condensation).
F Never place heavy objects on, or apply pressure to the controller that may cause it to
deform and deterioration during use or storage.
F 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.

1.2 Input and Output
The E5CK supports the following four outputs.
Control output 1
Control output 2
Auxiliary output 1
Transfer output
When using control outputs 1 and 2, set the output unit (sold separately).
Eight output units are available to suit the output circuit configuration.
When using transfer output, add on the communication unit (E53-CKF).
Note: The output functions of the E5CK do not operate for five seconds afĆ
ter the E5CK is turned ON.
F Output assign-
ments
The E5CK supports the following eight output functions.
Control output (heat)
Control output (cool)
Alarms 1 to 3
LBA
Error 1 (input error)
Error 2 (A/D converter error)
Assign these output functions to control outputs 1 and 2 and auxiliary outĆ
put 1.
Only control output (heat), control output (cool), alarms 1 to 3, and LBA
can be assigned to control outputs 1 and 2. Also, only alarms 1 to 3, LBA,
and errors 1 and 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 configuraĆ
tion is such that heating control output is connected to control output 1,
and alarm output is connected to control output 2 and auxiliary output 1.
In a heating and cooling control, assign control output (cool)" to either
of control output 1" or control output 2".
F Transfer output
The E5CK supports the following five transfer outputs.
Set point
Set point during SP ramp
Process value
Heating side manipulated variable
Cooling side manipulated variable
These transfer outputs can be output after being scaled. Setting of an
upper limit value smaller than the lower limit value is allowed, so reverse
scaling can also be carried out.

F Expansion mode
Set the controller to this mode during normal operation. In this mode, you
may change the set point during operation, and stop and start operation.
You can also monitor (not change) the process value, ramp SP and manipĆ
ulated variable.
This is the main mode for adjusting control. In this mode, you can execute
AT (autoĆtuning), and set alarm values, the control period and PID paramĆ
eters.
This is the auxiliary mode for adjusting control. In this mode, you can 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.
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.
This is the mode for setting expanded functions. In this mode, you can set
ST (selfĆtuning), SP setting limiter, selection of advanced PID or ON/OFF
control, specification of the standby sequence resetting method, initializaĆ
tion of parameters, time for automatic return to the monitoring display.

JSelecting modes
This is the mode for setting option functions. You can select this mode only
when the option unit is set 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 set in the controller.
This mode is provided so that the user can calibrate inputs and transfer
output.

1.4 About the Communications Function
1.4 About the Communications Function
The E5CK 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 RS-232C interface, add

CHAPTER 1 INTRODUCTION
1.5 About Calibration
The E5CK controller is calibrated before shipment from the factory. So,
the user need not calibrate the E5CK controller during regular use.
However, if the E5CK controller must be calibrated by the user, use the
parameters provided for user to calibrate temperature input, analog input
(voltage, current) and transfer output.
Also, note that calibration data is updated to the latest value each time the
E5CK controller is calibrated. Calibration data set before shipment 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 the parameter is the item to be calibrated. The
E5CK 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 can be calibrated when the communications unit
(E53-CKF) 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 calibrating the E5CK controller.
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
devices and equipment. For details on handling these measuring devices
and equipment, refer to the respective manuals.

Ă• For details on input types and setting ranges, see page 5Ć22.
Ă• When the voltage input and current input are selected, scaling matched
to the control is required.
Ă• The scaling upper limit", scaling lower limit" and decimal point"
parameters (setup mode) are use for scaling.
Ă• The scaling upper limit" parameter sets the physical quantity to be
expressed 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.

Ă• When temperature input is selected, scaling is not required. 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
sensor can be shifted. For example, if both the upper and lower limit valĆ
ues 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.

error 2 (A/D converter error).
These functions are assigned to control outputs 1 and 2, and auxiliary

Selecting the Control Method (page 4Ć2).
Ă• The same output function can not be assigned to a single destination
more than once.
Ă• Factory settings are as follows:
Control output (heat) = control output 1
Alarm 1 = control output 2
Alarm 2 = auxiliary output 1.
Ă• Output assignments are set in the control output 1 assignment", conĆ

Ă• Direct operation" (or normal operation) refers to control where the
manipulated variable is increased according to the increase in the proĆ
cess value. Alternatively, reverse operation" refers to control where the
manipulated variable is decreased according to the decrease in the proĆ
cess value.
For example, when the process value (PV), is lower than the set point
(SP), in a heating control system, the manipulated variable increases by
the difference between the PV and SP values.
Accordingly, this becomes reverse operation" in a heating control system.
Alternatively, this becomes direct operation" in a cooling control system.

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

If the heating and cooling characteristics of the control target greatly difĆ
fer, preventing satisfactory control characteristics from being obtained by
the same PID parameters, adjust the proportional band (P at cooling side)
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
Ă• In heating and cooling control, the manipulated variable output that is
output when controller operation is stopped is dependent on the set
value of the “MV at stop" 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 STOP 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.
The factory setting is 0". If the controller is operated using the factory
setting, 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.

F MV limiter
The upperĆand lowerĆlimit values of the manipulated variable can be
restricted by the MV limiter, and the change rate of the manipulated variĆ
able can be restricted by the MV change rate limiter.
The upperĆand 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 E5CK is outside of the
range of the MV limiter, actual outputs are dependent on the set value of
these parameters.

Ă• During ST execution
Ă• During AT execution (only by MV change rate limiter)
Ă• During manual operation
Ă• When operation is stopped
Ă• When an error has occurred.
The setting range of the set point is limited by the set point limiter. The
upperĆand lowerĆlimit values of this set point limiter are set in the “Set
point upper limit" and “Set point lower limit" parameters (expansion
mode), respectively. However, note that when the set point limiter is reset,
the set point is forcibly changed to the upperĆor lowerĆlimit value of the set
point limiter if the set point is out of the limiter range. Also, when the inĆ
put type, temperature unit and scaling (sensor) range are changed, set
point limiter is forcibly reset to the scaling (sensor) range.

Ă• When using event input, add on the input unit (E53ĆCKB).
Ă• You can choose from the following three event input functions:
Run/Stop
Auto/Manual
MultiĆSP
Ă• When selecting an option function, first determine whether or not the
multiĆSP function is to be used. You can select two of the remaining
option functions only when the multiĆSP function is not in use.
Ă• When using the multiĆSP function, set the multiĆSP function" parameĆ
ter (option mode) to 1: ON". When using other functions, set this
parameter to 0: OFF".
Ă• When specifying event input other than the multiĆSP function, specify
event input in the event input assignmen 1" parameter (option mode).
The following table shows the relationship between parameter settings
and event input functions.
Setting Function
ON : Stop /OFF : Run
ON : Manual /OFF : Auto
Ă• When event input is set to ON", controller operation is stopped and the
STOP" LED lights. The content of event input is reflected in the “run/
stop" parameter (level 0 mode).
Ă• Run/Stop can be switched up to 100,000 times.
F Auto/Manual
About the event input and key operation
Ă• When event input is set to ON", the controller is switched for manual
operation, and the MANU" LED lights.
Ă• Turn event input ON/OFF while the controller is ON.
Ă• Auto/Manual can be switched up to 100,000 times.
There is no order of priority when inputting events and operating the keys. However,
because event input of run/stop or auto/manual must be carried out in either of the
physical ON/OFF states, parameters ultimately conform to event input even if an
attempt is made to switch the setting by key operation.

Ă• The set points set to the set point 0" and set point 1" parameters (level
1 mode) can be switched for use. However, note that these parameters
cannot be set when the multiĆSP function is not selected.
Ă• The set point can be switched up to 100,000 times.
Ă• When event input is OFF", set point 0 is used, and when ON" set point
1 is used.
Ă• When you have changed the set point, the set point of the currently
selected parameter is changed.
Ă• When you have switched between set point 0" and set point 1", the SP
ramp function works if the SP ramp function is enabled. The following
examples shows how the set point changes when you switch from set
point 0 and set point 1.

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
lower limit value is allowed, so reverse scaling can also be carried out.
Also, the scale can be enlarged by the upperĆand lowerĆlimit width speciĆ
fied for each data item. The following example shows scaling of the readĆ

Ă• The LBA (Loop Break Alarm) function can be used only when assigned
as an output. Also, the LBA function does not work when a memory
error or A/D converter error occurs.
Ă• LBA (Loop Break Alarm) is a function for judging 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.
F LBA detection

F LBA detection
example
Ă• Normally, when output is set to maximum or minimum, the process
value rises or falls after the dead time has elapsed. LBA is output if the
process value does not change in the predicted direction after a fixed
amount of time has elapsed. This fixed amount of time is the LBA detecĆ
tion 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
at maximum output.

Ă• LBA judgment is carried out at each LBA detection time from the point
of maximum output. In above figure, the process value (PV) is changing
greatly at the 1st judgment timing, so LBA remains OFF.
Ă• At the 2nd judgment timing, the process value increases as indicated by
the broken line of 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 timing and
the LBA output becomes ON.

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 (default: 0.2 % fullĆscale).
(3) Take a value twice that of the measurement time as the LBA detection
time.

Conditions of Use
The transfer output function must be in
use.
Transfer output upper limit
Transfer output lower limit
Ă• These parameters set the transfer output conditions.
Ă• The transfer output type" parameter selects one of the following as the transfer outĆ
put type, and assigns this to transfer output:
Set point, Set point during SP ramp, Process value, Manipulated variable (heat), and
Manipulated variable (cool).
However, note that manipulated variable (cool)" can be selected only during heating
and cooling control.
Ă• The transfer output upper limit" and transfer output lower limit" parameters are
used for scaling of transfer output. The setting range varies according to this output
data. Also, a lower limit value larger than the upper limit value may be set.
Ă• During temperature input, the decimal point position of the set point, set point durĆ
ing SP ramp or process value is dependent on the currently selected sensor, and durĆ
ing analog input on the results of scaling.

Calibration Mode
Ă• The parameters in this mode can be used only when the security" parameter (proĆ
tect mode) is set to 0". When selecting this mode for the first time after the E5CK
has left the factory, return the security" parameter to 0".
Ă• This mode contains the parameters for user calibration of inputs and outputs. Only
parameters relating to input types specified in the input type" parameter (setup
mode) can be used. Also, related output parameters can be used only when the comĆ
munications unit (E53ĆCKF) is added on.

CHAPTER 6 USING THE COMMUNICATIONS FUNCTION
6.1 Outline of the Communications Function
JOutline
The communications function allows you to monitor and set E5CK
parameters by a program prepared and running on a host computer conĆ
nected to the E5CK controller. This chapter describes operations as
viewed from the host computer.
When using the communications function, the option unit for RSĆ232C or
RSĆ485 communications must be added on. The E5CK communications
function allows you to carry out the following:
Ă• Reading/writing of parameters;
Ă• Operation instructions; and
Ă• Selecting the setting level.
The communications function assumes the following conditions:
Ă• Writing of parameters is possible in during remote operation. Also,
parameters cannot be written during execution of autoĆtuning;
Ă• Writing parameters are provided with a setting level. Writing conditions
are as follows depending on the setting level:
Setting level 1: No restrictions
Setting level 0: Writing of parameters in the setup and expansion modes
only is prohibited.
Ă• For details on switching between setting levels, see page 6Ć9.
Ă• The run/stop", remote/local" and AT execute/cancel" parameters are
set aside from other parameters as special commands for instructing
operations.

The host computer sends a command frame" to the controller, and the
controller returns a response frame" corresponding to the content of the
command sent by the host computer. In other words, a response frame is
returned for each command frame sent.
The following diagram shows command frame/response frame operaĆ
tions.
