PRECAUTIONS FOR ENSURING CORRECT USE
FUse 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.
FAttach a surge suppressor or noise filter to peripheral devices that generate noise (in particular, motors,
transformers, solenoid s , m a g ne tic coils or other equipme nt that h a ve a n ind u ctance compone nt ) .
FWhen mounting a noise filter on the power supply, be sure to first check the filter’s voltage and cur
rent capacity, and then mount the filter as close as possible to the controller.
FInsert a noise filter (TDK ZCB220611 or equivalent) on the AC power line to satisfy conducted emis
sion rating (FCC Regulation Class A EN500812compliant).
FUse 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 subject ed to heat rad iation, us e a fan to cool the surfa ce of the controlle r to under 55°C.
FStore within the following temperature and humidity ranges:
•Temperature: 25 to 65°C, Humidity: 35 to 85% (with no icing or condensation)
FNever place heavy objects on, or apply pressure to the controller that may cause it to deform and dete
riorate during use or storage.
FAvoid 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.

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 pre
venting 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 manip
ulated 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 parame
ters 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, 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, specifi
cation of the standby sequence resetting method, time for automatic
return to the monitoring display.

1.4 About the Communications Function for
the CompoBus/D (DeviceNet) Network
The E5EKDRT operates as a slave on the CompoBus/D (DeviceNet) net
work. Items (parameters, operation instructions and statuses) that have
been assigned as communication data on the E5EKDRT can be uploaded
and downloaded between masters and slaves.
16 read and write operations can be assigned as communication data, and
can be assigned.

As the data structure is flexible like this, communications is possible using
numerous parameter configurations, and the number of parameters can
be limited to increase processing speed.
For details on the type of communication data and how to assign data, see
Chapter 6 Using CompoBus/D (DeviceNet).
For details on cable connections on the CompoBus/D (DeviceNet) net
work, see Chapter 2 Preparations, 2.3 Wiring Terminals (page 27).

tion and related system devices, see the CompoBus/D (DeviceNet) Opera
tion Manual (catalog No.: W267).

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.
The input type selected in the parameter is the item to be calibrated. The
E5EKDRT is provided with the following four calibration parameters.
•Thermocouple
•Platinum resistance thermometer
•Current input
•Voltage input
Two parameters are provided for thermocouple, platinum resistance ther
mometer and voltage input.
When calibrating each item, the calibration data is temporarily regis
tered. This data can be registered as final calibration data only when all
items have been newly calibrated. So, all items must be temporarily regis
tered 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.
For details, see chapter 7 Calibration.
