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 area around the E5EK. (Ensure sufficient space around the controller to allow heat radiation.)
F Use a voltage (AC100-240V or AC/DC24V at 50 to 60 Hz). At power ON, the prescribed 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 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 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.
F Ambient temperature must be kept between -10_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 -25_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.

JHow to use keys
F key
F key
The following describes basic key operations.
Each press of this key switches between the auto and manual operations.
The functions of this key change according to how long it is pressed. If the key is pressed for less than one second, the parameters are switched. If the key is pressed for one second or more, the menu display appears. In key operations from here on, “press the key” refers to pressing the key for less than one second.
For details on parameter switching and menu display items, see page 1-8.
F |
key |
Each press of the |
key increments or advances the values or settings |
|
|
|
on the No.2 display, while each press of the |
key decrements or |
|
|
|
returns the values or settings on the No.2 display. |
Functions vary, for example, when the key is held down simultaneously with the display key, or a key is held down continuously. For details, see page 1-8. Also, chapters 3 and 4 describe examples using various key combinations.

When using transfer output, add on the communication unit |
|
|
(E53-AKF). |
|
|
Note: The output functions of the E5EK do not operate for five seconds |
|
|
after the E5EK is turned ON. |
|
F Output assign- |
The E5EK supports the following ten output functions. |
|
ments |
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 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-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 output 2, auxiliary output 1, and |
|
|
auxiliary output 2) 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 configu- |
|
|
ration is such that heating control output is connected to control output |
|
|
1, and alarm output is connected to control output 2 and auxiliary out- |
|
|
put 1. |

F Transfer output |
The E5EK supports the following six transfer outputs. |
|
Set point |
|
Set point during SP ramp |
|
Process value |
|
Heating side manipulated variable |
|
Cooling side manipulated variable |
|
Valve opening |
|
However, note that heating/cooling side manipulated variables can be |
|
output only standard type controllers, and valve opening can be output |
|
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. |

1.3 Parameters and Menus
1.3 Parameters and Menus
JParameter types
F Protect mode
E5EK 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 menu and keys. The protect function is for preventing unwanted modification of parameters and switching between the auto and manual operation.
F Manual mode |
In this mode, the controller can be switched manual operation. The |
|
manipulated variable can be manipulated manually only in this mode. |
F Level 0 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 op- |
|
eration. You can also monitor (not change) the process value, ramp SP |
|
and manipulated variable. |
F Level 1 mode |
This is the main mode for adjusting control. In this mode, you can |
|
execute AT (auto-tuning), and set alarm values, the control period and |
|
PID parameters. |
F Level 2 mode |
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. |
F Setup mode |
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 opera- |
|
tion. |
F Expansion mode |
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. |
F Option mode |
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 |
|
1--7 |

||
|
SP scaling parameters are also located in this mode. |
|
|
F Calibration mode |
This mode is provided so that the user can calibrate inputs and transfer |
||
|
output. |
|
|
|
When calibrating input, the selected input type is calibrated. Whereas, |
||
|

CHAPTER 1 INTRODUCTION
1.4 About the Communications Function
|
|
|
The E5EK 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 |
When using the communications function on the RS-232C interface, |
|
add on the communications unit (E53-AK01). |
F RS-422 |
When using the communications function on the RS-422 interface, add |
|
on the communications unit (E53-AK02). |
F RS-485 |

1.5 About Calibration
1.5 About Calibration
|
|
|
The E5EK controller is calibrated before shipment from the factory. So, |
|
the user need not calibrate the E5EK controller during regular use. |
|
However, if the E5EK 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 E5EK controller is calibrated. Calibration data set before shipment |
|
from the factory cannot be returned to after calibration by the user. |
F Calibrating |
The input type selected in the parameter is the item to be calibrated. |
inputs |
The E5EK 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. |
FCalibrating transfer output
FRegistering calibration data
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 E5EK 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.
