NOTICE

Be sure to observe these precautions to ensure safe use.

(1) Do not wire the terminals which are not used.
(2) Be sure to wire properly with correct polarity of terminals.
(3) To reduce induction noise, separate the high-voltage or large-current power lines from other

lines, and avoid parallel or common wiring with the power lines when you are wiring to the
terminals. We recommend to use separating pipes, ducts, or shielded lines.

(4) Do not use this product in the following places:

• P laces subject to dust or corrosive gases (in particular, sulfide gas and ammonia gas)

• Places subject to high humidity, condensation or freezing.

• Places subject to direct sunlight.

• P laces subject vibration and large shocks.

• Places subject to splashing liquid or oil atmosphere.

• Places directly subject to heat radiated from heating equipment.

• Places subject to intense temperature changes.

• Places subject to flammable or explosive gas.

(5) To allow heat to escape, do not block the area around the product. (Ensure enough space for

heat to escape.)

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

inside.

(7) Cleaning: Do not use paint thinner or the equivalent. Use standard grade alcohol to clean the prod-

uct.
(8) Use specified size (M3.5, width 7.2mm or less) crimped terminals for wiring.
(9) Allow as much space as possible between the controller and devices that generate a powerful

high-frequency (e.g. high-frequency welders, high-frequency sewing machines) or surge.

PRECAUTIONS FOR ENSURING CORRECT USE

F Use a 100 to 240 V AC (50/60 Hz), 24 VAC (50/60 Hz) or 24 VDC power supply matched to the

power specifications of the E5EK-DRT. Also, make sure that rated voltage is attained within two
seconds of turning the power ON.

F Attach a surge suppress or or noise filter to periphe ra l devices that generate noise (in particular,

motors, transformers, solenoids, magnetic coils or other equipment that have an inductance compo­nent).

F When mounting a noise filter on the power supply, be sure to first check the filter’s voltage and

current capacity, and then mount the filter as close as possible to the controller.

F Insert a noise filter (TDK ZCB2206-11 or equivalent) on the AC power l ine to satisfy conducted

emission rating (FCC Regulation Class A EN50081-2-compliant).

F Use within the following temperature and humidity ranges:

• Temperature: -10 to 55°C, Humidity: 35 to 85% (with no icing or condensation)
If the E5EK-DRT is installed inside a control board, the ambient temperature must be kept to
under 55°C, including the temperature around the controller.
If the controller is subjecte d 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 to 65°C, Humidity: 35 to 85% (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 Expansion mode

E5EK-DRT parameters are distributed between the following nine
modes.

Protect mode
Manual mode
Level 0 mode
Level 1 mode
Level 2 mode
Setup mode
Expansion mode
Option mode
Calibration mode

The settings of parameters in each of seven modes (excluding the pro­tect mode and manual mode) can be checked and modified by selection
on the menu display.

This mode is used to limit use of the keys. The protect function is for
preventing unwanted modification of parameters and switching
between the auto and manual operation.

In this mode, the controller can be switched 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 may change the set point during operation, and stop and start op­eration. You can also monitor (not change) the process value, ramp SP
and manipulated variable.

This is the main mode for adjusting control. In this mode, you can
execute AT (auto-tuning), and set alarm values, the control period, PID
parameters and heater burnout al arm (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, switch between the SP 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, SP setting limiter, selection of 2 -PID control or ON/OFF control,
specification of the standby sequence resetting method, time for auto­matic return to the monitoring display.

CHAPTER 1 INTRODUCTION

1.5 About Calibration

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

However, if the E5EK-DRT controller must be calibrated by the user,

use the parameters provided for user to calibrate temperature input,
analog input (voltage, current). 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

the E5EK-DRT controller is calibrated. Calibration data set before ship­ment from the factory cannot be returned to after calibration by the
user.

F Calibrating

inputs

F Registering

calibration data

The input type selected in the parameter is the item to be calibrated.
The E5EK-DRT is provided with the following four calibration parame-

ters.

• Thermocouple

• Platinum resistance thermometer

• Current input

• Voltage input

Two parameters are provided for thermocouple, platinum resistance
thermometer and voltage input.

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 calibrating the E5EK-DRT 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.

CHAPTER 3 BASIC OPERATION

3.1 Convention Used in this Chapter

This chapter describes basic E5EK-DRT operations such as how to set
up parameters, start and stop operation, and adjusting control opera-

tion.

For more complex control examples, refer to Chapter 4 Applied Opera­tion and Chapter 5 Parameters.

Power OFF

This chapter describes basic operation according to this flow. Examples
of operation for each of these items are described at the end of the set­ting examples for the parameter in question. However, you must pro-

ceed to the first parameter of the subsequent item.

For example, to perform “setting output specifications” after complet-

ing “setting input specifications,” proceed to the first parameter of “set­ting output specifications” from the final parameter of “setting input
specifications.” For details on moving parameters between items, follow

the procedures in “Selecting modes” and “Selecting parameters”
described on pages 1-7 and 1-8.
