PayAttention to the Following when Installing
this Controller

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

tronic parts inside.

F Do not cover the area around the E5AK. (Ensure sufficient space around the control-

ler to allow heat radiation.)

F Use a voltage (AC100-240V

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:

• 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 currents.

• Using separating p ipes, 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

powerful, high frequency (high-frequency welders, high-frequency sewing machines,
and so forth) or surge. These devices may cause malfunctions.

F If there is a large power-generating 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

(especially sulfurized gas or ammonia gas), shock, vibration, splashing liquid, or oil
atmosphere 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 pre-

F Ambient temperature must be kept between -10_Cto55_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 -25_Cto65_C. T he amb ient

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 installa-

tion. These devices can cause radio disturbances which adversely affect the perfor­mance of the controller.

1.1 Names of parts

F Event input

JOutput

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

Multi-SP
Run/Stop
Remote/Local
Auto/Manual
SP mode

The E5AK supports the following five outputs.

Control output 1
Control output 2
Auxiliary output 1
Auxiliary output2
Transfer output

When using control outputs 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).

Note: The output functions of the E5AK do not operate for five seconds

after the E5AK is turned ON.

F Output assign-

ments

The E5AK supports the following ten output functions.

Control output (heat)
Control output (cool)
Alarms 1 to 3
HBA
LBA
Error 1 (input error)
Error 2 (A/D converter error)
Error 3 (RSP input error)

Assign these output functions to control output 1, control output 2,
auxiliary output1, and auxiliary output2.
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 (E5AK-PRR2), 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 output2, auxiliary output1, and
auxiliary output2) can be used. For details, see 3.3 Setting Output Spec­ifications.

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.

PID parameters.

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 ST (self-tuning), SP setting limiter, selection of advanced PID or
ON/OFF control, specification of the standby sequence resetting
method, time for automatic return to the monitoring display.

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

CHAPTER 1 INTRODUCTION

1.4 About the Communications Function

The E5AK 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).

1.5 About Calibration

The E5AK controller is calibrated before shipment from the factory. So,
the user need not calibrate the E5AK controller during regular use.

However, if the E5AK 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 E5AK controller is calibrated. Calibration data set before shipment
from the factory cannot be returned to after calibration by the user.

1.1 Names of parts

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 E5AK 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 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 calibrating the E5AK 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.

For details, see Chapter 7 Calibration.

• Use ducts to separate input leads and power lines in order to protect
the controller and its lines from external noise.

• We recommend using solderless terminals when wiring the controller.

• Ti ghten the terminal screws using a torque no greater than 0.78 N·m,

or 8 kgf·cm max. Take care not to tighten the terminal screws too
tightly.

• Use the following type of solderless terminals for M3.5 screws.

7.2mm max.
