PRECAUTIONS ON SAFETY
Marks For Ensuring Safe Use and Their Meanings
This manual uses the following marks to indicate precautions for ensuring that the
E5AKĆT 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
tancy. 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 E5AKĆT. (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.

Ă• Assign these output functions to control output 1, control output 2, auxĆ
iliary output 1, and auxiliary output 2.
However, note that as control output 1 is used as the open output and
control output 2 is used as close output on a positionĆproportional type
controller (E5AKĆTPRR2), control outputs 1 and 2 cannot be used as asĆ
signment destinations. Also, of the output functions, control output
(heat), control output (cool), HBA and LBA are disabled.
Ă• On a standard type controller, there are restrictions on how assignment
destinations (control output 1, control output 2, auxiliary output 1, and
auxiliary output 2) can be used. For details, see Chapter 3 Basic OperaĆ
tion/3.3 Setting Output Specifications (page 3Ć7).
Ă• 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• Control outputs 1 and 2 are used depending on the differences in control
method as follows:

Ă• The E5AKĆT supports the following five transfer outputs:
Set point, Process value, Heating side manipulated variable,
Cooling side manipulated variable, Valve opening
However, note that heating/cooling side manipulated variables can be outĆ
put only on standard type controllers, and valve opening can be output
only on positionĆproportional type controllers.
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.

CHAPTER 1 INTRODUCTION
1.3 Program
JHow programs
are structured
E5AKĆT allows you to configure programs made up of a maximum of eight
patterns (pattern 0 to 7).
The number of steps (16 maximum) in each pattern can be specified in paĆ
rameters.
Pattern 7
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.

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 7 (Run all).
Ă• During program operation, steps can be skipped (Advance) and the conĆ
trol monitoring can be paused (Hold).
Ă• When the wait width is specified in parameter setup, the program does
not go to the next step and waits until the PV reaches the specified time
(wait width) at the end of each step.
Ă• Alarms that are assigned as outputs operate referenced to the alarm valĆ
ues preset to each pattern.
Ă• Time signals, program end and stage output can be output according to
output assignment.
Ă• ON/OFF signals are output as time signals according to the timer that
takes a specified step as its start point.
1.4 Parameters and Menus
1.4 Parameters and Menus
JParameter types
F Protect mode
F Manual mode
E5AKĆT 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 and heatĆ
er burnout alarm (HBA) conditions.
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.

CHAPTER 1 INTRODUCTION
F Expansion mode
F Option mode
F Calibration mode
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. HeatĆ
er burnout alarm function and positionĆproportional travel time are also
located in this mode.
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
(E53ĆAKF) is set in the controller.
The following diagram shows the order in which modes are selected.

Ă• Protected modes cannot be selected. Also, the menu display does not apĆ
pear when modes are protected up to the program mode.
Ă• If you select [ ], [ ], [ ] or [ ] in the menu display, the
level 0, program, level 1 and level 2 modes, respectively, are selected.
These modes are selected with control still continuing.
Ă• If you select[ĂĂ ] [ĂĂ ] [ĂĂ ] or [ĂĂ ] in the menu display, the
setup, expansion, option and calibration modes, respectively, are seĆ
lected.
When these modes are selected, the control is reset. So, control outputs
and auxiliary output are turned OFF. When another mode is selected
while in these modes control, reset is canceled.
Ă• To set the controller to the protect mode or to return to the level 0 mode
from the protect mode, press the

CHAPTER 1 INTRODUCTION
1.5 About the Communications Function
The E5AKĆT 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-422
F RS-485
When using the communications function on the RSĆ232C interface, add
on the communications unit (E53ĆAK01).
When using the communications function on the RSĆ422 interface, add on
the communications unit (E53ĆAK02).
When using the communications function on the RSĆ485 interface, add on
the communications unit (E53ĆAK03).
1–12
1.6 About Calibration
The E5AKĆT controller is calibrated before shipment from the factory. So,
the user need not calibrate the E5AKĆT controller during regular use.
However, if the E5AKĆT 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 E5AKĆT controller is calibrated. Calibration data set before shipĆ
ment from the factory cannot be returned to after calibration by the user.
1.6 About Calibration
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
E5AKĆT 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
(E53ĆAKF) 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 E5AKĆT 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.
For details, see Chapter 7 Calibration.
