PRECAUTIONS ON SAFETY

F Marks For Ensuring Safe Use and Their Meanings

This manual uses the following marks to indicate precautions for ensuring that the
E5EK-T 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.

F Do not use the product in places where explosive or flammable gases may be present.

F Never disassemble, repair or modify the product.

F Tighten the terminal screws properly.

F Use the specified size of solderless terminals for wiring.

F Use the product within the rated supply voltage.

F Use the product within the rated load.

F 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
expectancy. If the output relay is used beyond its life expectancy, its contacts may become fused or
burned.

F If you remove the controller from its case, never touch nor apply shock to the electronic parts

inside.

F Do not cover the E5EK-T. (Ensure sufficient space around the controller to allow heat radiation.)

F Do not use the controller in the following places:

• Places subject to icing, condensation, dust, corrosive gas (especially sulfide gas or ammonia gas).

• Places subject vibration and large shocks.

• Places subject to splashing liquid or oil atmosphere.

• Places subject to intense temperature changes.

• Places subject to heat radiation from a furnace.

F Be sure to wire properly with correct polarity of terminals.

F When wiring input or output lines to your controller, keep the following points in mind to reduce

the influence from inductive noise:

• Allow adequate space between the high voltage/current power lines and the input/output lines.

• Avoid parallel or common wiring with high voltage sources and power lines carrying large cur-

rents.

• Using separating pipes, ducts, and shielded line is also useful in protecting the controller, and its
lines from inductive noise.

F Cleaning: Do not use paint thinner or organic solvents. Use standard grade alcohol to clean the

product.

F 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.

F Allow as much space as possible between the controller and devices that generate a powerful high

frequency (high-frequency welders, high-frequency sewing machines, etc.) or surge. These devices
may cause malfunctions.

F If there is a large power-generating peripheral device and any of its lines near the controller, at-

tach 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.

F When mounting a noise filter on the power supply to the controller, be sure to first check the fil-

ter’s voltage and current capacity, and then mount the filter as close as possible to the controller.

V

F Use within the following temperature and humidity ranges:

• Temperature: -10_Cto55_C, 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 un ­der 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 within the following temperature and humidity ranges:

• Temperature: -25_Cto65_C, humidity: 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

deteriorate 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.

F Temperature input/Voltage input/Current input

• Only one of temperature input, current input and voltage input can
be selected and connected to the controller.

• The following input sensors can be connected for temperature input:

Thermocouple:K,J,T,E,L,U,N,R,S,B,W,PLII
Platinum resistance thermometer: JPt100, Pt100

• The following currents can be connected for current input:

4to20mA,0to20mA

• The following voltages can be connected for voltage input:

1to5VDC,0to5VDC,0to10VDC

F CT input/Poten -

tiometer

• Connect CT input when using the HBA (heater b urnout alarm) func­tion on a standard type controller (E5EK-TAA2). Note that CT input
cannot be used when the linear output unit is mounted.

• Connect the potentiometer when monitoring the valve opening on a
position-proportional type controller (E5EK-TPRR2).

CHAPTER 1 INTRODUCTION

F Event input

JOutput

F Ou tput assign-

ments

Add on the input unit (E53-CKB) when using event input. You can se­lect from the following five event inputs:

Run/Reset, Auto/Manual, Hold/Hold Cancel, Advance, Pattern

The output functions of the E5EK-T do not operate for five seconds after the
E5EK-T is turned ON.

The E5EK-T supports the following five outputs:

Control output 1
Control output 2
Auxiliary output 1
Auxiliary output 2
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 config­uration.

When using transfer output, add on the communication unit
(E53-AKF).

• The E5EK-T supports the following thirteen output functions:

Control output (heat), Control output (cool), Alarms 1 to 3, HBA,
LBA, Time Signals 1 and 2, Program End, Stage Output,
Error 1 (input error), Error 2 (A/D converter error)

• Assign these output functions to control output 1, control output 2,
auxiliary 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 position-proportional
type controller (E5EK-TPRR2), control outputs 1 and 2 cannot be
used as assignment destinations. Also, of the output functions, control
output (heat), control output (cool), HBA and LBA are disabled.

• 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 Operation/3.3 Setting Output Specifications (page 3-7).

• 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
configuration 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.

• Control outputs 1 and 2 are used depending on the differences in con­trol method as follows:

• The E5EK-T 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
output only on standard type controllers, and valve opening can be out­put only on position-proportional type controllers.

• 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.

CHAPTER 1 INTRODUCTION

1.3 Program

JHow programs

are structured

E5EK-T allows you to configure programs made up of a maximum of
four patterns (pattern 0 to 3).
The number of steps (16 maximum) in each pattern can be specified in

parameters.

Pattern 3

Pattern 1

Pattern 0

Step 0 Step 1 Step 2 Step 15

• Generally, the “time setup method” is used to configure programs. By

this method, set points at each step and time are used as program ele­ments. 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

F Wait operation

JAlarm output

JProgram output

1--8

• Generally, the target patterns are specified before the program is

executed.

• In parameter setup, you can specify repeated execution of the same

pattern (Repeat) or consecutive execution of all patterns 0 to 3 (Run
all).

• During program operation, steps can be skipped (Advance) and the

control monitoring can be paused (Hold).

• 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.

• Alarms that are assigned as outputs operate referenced to the alarm

values preset to each pattern.

• Time signals, program end and stage output can be output accor din g

to output assignment.

• 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

F L evel 0 mode

E5EK-T 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 param-

eters, and switching between run and reset operation or auto and
manual operation.

In this mode, the controller can be switched to manual operation. The

manipulated variable can be manipulated manually only in this mode.

Set the controller to this mode during normal operation. In this mode,
you can change the set p oint 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.

F Program mode

F L evel 1 mode

F L evel 2 mode

F Setup mode

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 (auto-tuning), and set up the control period, PID parame­ters and heater 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 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.

1--9

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 p ro­gramming, 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 control-

ler. Heater burnout alarm function and position-proportional 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
(E53-AKF) is set in the controller.

The following diagram shows the order in which modes are selected.

CHAPTER 1 INTRODUCTION

1.5 About the Communications Function

The E5EK-T 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 RS -232C interface,
add on the communications unit (E53-AK01).

When using the communications function on the RS-422 interface, add
on the communications unit (E53-AK02).

When using the communications function on the RS-485 interface, add
on the communications unit (E53-AK03).

1.6 About Calibration

The E5EK-T controller is calibrated before shipment from the factory.
So, the user need not calibrate the E5EK-T controller during regular

use.

However, if the E5EK-T 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 results of calibration will not be assured.
Also, note that calibration data is updated to the latest value each time
that the E5EK-T controller is calibrated. Calibration data set before
shipment from the factory cannot be returned to after calibration by

the user.

F Registering cal-

ibration data

The input type selected in parameters is the item to be calibrated. The
E5EK-T is provided with the following four calibration parameters:

• Thermocouple

• Platinum resistance thermometer

• Current input

• Voltage input

Two parameters are provided for thermocouple and voltage input.

Transfer output also can be calibrated when the communications unit
(E53-AKF) is added on.

When calibrating each item, the calibration data is temporarily regis­tered. This data can be registered as final calibration data only when all
items have been newly calibrated. So, all items must be temporarily
registered when the E5EK-T 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 de­vices and equipment. For details on handling these measuring devices

and equipment, refer to the respective manuals.

For details, see Chapter 7 Calibration.

CHAPTER 2 PREPARATIONS

2.1 Setup

• On a standard type controller, set up the output units for control out­puts 1 and 2 before mounting the controller.

• On a position-proportional type controller, the relay output unit is
already mounted. So, this setup operation is unnecessary. (That is, do
not replace the currently mounted unit with other output units.)

• When setting up the output units, draw out the internal mechanism
from the housing, and insert the output units into the sockets for con­trol outputs 1 and 2.

JDraw-out

When drawing out the internal mechanism from the housing, prepare a

Phillips screwdriver matched to the size of the screw on the lower part
of the front panel.

(1) Press down on the hook on the top of the front panel, and turn the

Phillips screwdriver to the left to loosen the screw on the lower

part of the front panel.

(2) Draw out the internal mechanism towards you holding both sides

of the front panel.

Tighten this screw by a torque of 0.3 to 0.5 N⋅m (approx. 3 to 5 kgf⋅cm).
