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
on the communications unit (E53-CK01).

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.
