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

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 suppressor or noise filter to peripheral 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 cur

rent 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 line to satisfy conducted emis

sion 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 dete

riorate 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.

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).

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.

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.

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 proceed to the
first parameter of the subsequent item.

For example, to perform setting output specifications" after completing
setting input specifications," proceed to the first parameter of setting
output specifications" from the final parameter of setting input specifica
tions." For details on moving parameters between items, follow the proce
dures in Selecting modes" and Selecting parameters" described on
pages 17 and 18.

The following are examples of how to set up each of the items. These exam
ples assume that the controller is operated at the factory defaults.

The main specifications of the setup examples in this chapter are as fol
lows:

• A K thermocouple is connected to the controller.
• The control output (heat) function is assigned to control output 1, and

the alarm 2 function is assigned to auxiliary output 1. A relay output
unit is also attached to control output 1.

• The upper limit alarm is set. In this example, alarm 2 is set. An alarm

is output when the temperature exceeds 10_C of the set point.

• To switch the temperature unit from _C" to_F" when input is temper

ature, switch the _C/_F selection" parameter (setup mode) from  "

to  ".

• When input is temperature input, the upper and lower limit values of the

sensor can be shifted linearly. For example, if both the upper and lower

limit values are shifted by 1.2_C, the process value (before shift) is re

garded as 201.2_C after shift when input is 200_C before shift.

• To set input shift, set shift values in the input shift upper limit" and in

put shift lower limit" parameters (level 2 mode).

• When the analog input (the voltage input and current input) is selected,

scaling matched to the control is available.

• The scaling upper limit", scaling lower limit" and decimal point" pa

rameters (setup mode) are used for scaling. These parameters cannot be

used when the temperature input type is selected.

• The scaling upper limit" parameter sets the physical quantity to be ex

pressed by the upper limit value of input, and the scaling lower limit"

parameter sets the physical quantity to be expressed by the lower limit

value of input. The decimal point" parameter sets the number of digits

past the decimal point.

• The following figure shows a scaling example of 4 to 20 mA input. After

scaling, the humidity can be directly read. In this case, the decimal

3.3 Setting Output Specifications

+ Output assignments

• Ten output are supported.

These functions are assigned to control outputs 1 and 2, and auxiliary
output 1 and 2.

• Restrictions on assignment destination are placed on some of the out

puts. The following table shows where outputs may be assigned to.

Error 3; RSP input error F F

With control output (cool), the conditions for switching from standard control
to heating and cooling control are reached when the output function is assigned
at the cooling side during heating and cooling control.

In other words, heating and cooling control is carried out when control
output (cool) is assigned, and standard control is carried out when out
put is not assigned. For details on heating and cooling control, see 4.1
Selecting the Control Method (page 42).

• Factory settings are as follows:

control output 1 = Control output (heat)
control output 2 = Alarm 1
auxiliary output 1 = Alarm 2
auxiliary output 2 = Alarm 3.

• Output assignments are set in the control output 1 assignment", con

trol output 2 assignment", aux output 1 assignment" and aux output
2 assignment" parameters (setup mode).

CHAPTER 3 BASIC OPERATION

• Direct operation" (or normal operation) refers to control where the

manipulated variable is increased according to the increase in the pro
cess value. Alternatively, reverse operation" refers to control where the
manipulated variable is decreased according to the decrease in the pro
cess value.
For example, when the process value (PV), is lower than the set point
(SP), in a heating control system, the manipulated variable increases by
the difference between the PV and SP values.
Accordingly, this becomes reverse operation" in a heating control system.
Alternatively, this becomes direct operation" in a cooling control system.

• Direct/reverse operation is set in the [ ]direct/reverse operation"

parameter (setup mode).

• When the output unit is pulse output such as relay output, set the pulse

output cycle (control period). Though a shorter pulse period provides
better control performance, the control period should be set taking the
life expectancy of the output unit into consideration when the output
unit is relay. It is recommended that the control period be set to longer
than 20 seconds.

• The control period is set in the control period (heat)" parameter (level

1 mode). Factory setting is 20:20 seconds."

• The control period (cool)" output function is not allocated. So, the

control period (cool)" parameter cannot be set.

3.4 Setting Alarm Type

• Three alarm outputs are supported: alarms 1 to 3. Of these, only the

alarm assigned as the output can be used.

• Alarm output conditions are determined according to the combination

of the alarm type", alarm value" and alarm hysteresis" parameter
settings.

• The contact conditions when alarm output is ON can be set to open"

or closed" in the close in alarm/open in alarm" parameter.

• “Standby sequence" is a function for unconditionally turning alarm out

put OFF when the process value has left the alarm range once and it next
enters the alarm range.

• For example, when the alarm type is set to “deviation lower limit," gener

ally the process value is within the alarm range, and alarm output
become ON as it is as the process value when the power is turned ON is
smaller than the set point. However, if the alarm type is set to deviation
lower limit with standby sequence", alarm output first becomes ON
when the process value exceeds the alarm setting value to leave the
alarm range and once again falls below the alarm value.

• When an alarm is output, the standby sequence is canceled. For details

on the standby sequence reset conditions, see Chapter 5, Expansion
Mode, Standby sequence reset method" on page 534.

+ Close in alarm/open in alarm

• When the controller is set to “close in alarm," the status of the alarm out

put function is output as it is. When set to “open in alarm," the status of
the alarm output function is output inverted.

• AT (autotuning) cannot be executed while operation is canceled or dur

ing ON/OFF control.

• When you execute autotuning, the optimum PID parameters for the

current set point at execution are automatically set by forcibly changing
the manipulated variable to calculate the characteristics (called the
limit cycle method") of the control target. During autotuning, the AT
LED flashes.

• 40%AT or 100%AT can be selected by the limit cycle of MV change width.

Specify [ ] or [ ], respectively, in the “AT execute/cancel" pa
rameter (level 1 mode).

• During heating and cooling control, only 100%AT can be executed. (So,

[ ] (40%AT) will not be displayed.)

• To cancel AT execution, specify [ ] (AT cancel").

In order to set the limit cycle of MV change width to 40%, select 40%AT
to execute autotuning with fluctuations in the process value kept to a
minimum. However, note that autotuning takes longer time to execute
compared with 100%AT.
The timing by which limit cycles are generated varies according to wheth
er or not the deviation (DV) at the start of AT execution is 10% fullscale
or less.

If the heating and cooling characteristics of the control target greatly dif
fer, preventing satisfactory control characteristics from being obtained by
the same PID parameters, adjust the proportional band (P at cooling side)
using the cooling coefficient to balance control between the heating and
cooling sides. In heating and cooling control, P at the heating or cooling
side is calculated by the following formula:

Heating side P = P; Cooling side P = cooling coefficient  P

•In heating and cooling control, the manipulated variable output that is

output when controller operation is stopped is dependent on the set
value of the “MV at stop" parameter (level 2 mode) in the same way as
for standard control.

• However, note that in heating and cooling control, the manipulated vari

able at the cooling side is treated as a negative value for the sake of conve
nience. When the manipulated variable at STOP is a negative value, the
manipulated variable is output to only the cooling side, and when a posi
tive value, the manipulated variable is output to only the heating side.
The factory setting is 0". If the controller is operated using the factory
setting, the manipulated variable is not output to both the heating and
cooling sides.

When the overlap band is set, the bumpless function that operates when switching
between manual and automatic operation may not work.

• Switching between 2PID control and ON/OFF control is carried out by

the PID / ON/OFF" parameter (expansion mode). When this parameter
is set to [ ], 2PID control is selected, and when set to [ ], ON/
OFF control is selected. Default is [ ].

• In ON/OFF control, hysteresis is provided in the program when switch

ing between ON and OFF to stabilize operation. The hysteresis width
provided during ON/OFF control is simply referred to as “hysteresis."
Control output (heat) and control output (cool) functions are set in the
“hysteresis (heat)" and “hysterisis (cool)" parameters, respectively.

4.2 Operating Condition Restrictions

The upperand lowerlimit values of the manipulated variable can be
restricted by the MV limiter, and the change rate of the manipulated vari
able can be restricted by the MV change rate limiter.

The upperand lowerlimit values of the manipulated variable are set in
the MV upper limit" and MV lower limit" parameters (level 2 mode).
When the manipulated variable calculated by the E5EKDRT is outside of
the range of the MV limiter, actual outputs are dependent on the set value
of these parameters.

The limiters are invalid or cannot be set when any of the following condi
tions occurs:

• During ON/OFF control
• During AT execution (only by MV change rate limiter)
• During manual operation
• When operation is stopped
• When an error has occurred.

The setting range of the set point is limited by the set point limiter. The
upperand lowerlimit values of this set point limiter are set in the “ Set
point upper limit" and “Set point lower limit" parameters (expansion
mode), respectively. However, note that when the set point limiter is reset,
the set point is forcibly changed to the upperor lowerlimit value of the set
point limiter if the set point is out of the limiter range. Also, when the in
put type, temperature unit and scaling (sensor) range are changed, set
point limiter is forcibly reset to the scaling (sensor) range.

“0", the SP ramp function is disabled.
The set point changing in SP ramp can be monitored in the “Set point dur
ing SP ramp" parameter (level 0 mode).

The limiters are invalid or cannot be set when any of the following condi
tions occurs:
If the SP ramp function is enabled when the power is turned ON, and when
“run" is switched to from “stop," process value may reach the set point af
ter SP ramp in the same way as when the set point is changed. In this case,
operation is carried out with the process value regarded as the set point
before the change was made.
The direction of the SP ramp changes according to the relationship be
tween the process value and the set point.

4.3 How to Use the Remote SP

• Taking a remote SP input (4 to 20 mA) as the set point is referred to as

the remote SP" function. The remote SP function is enabled only when
the remote SP (RSP) enable" parameter (option mode) is set to ON".

• Remote SP upperand lowerlimit values can be set by scaling.
• Inputs within the range 4 to 20 mA (10 to 110%) are allowed as remote

SP inputs. Inputs not within this range are regarded as outofrange
input values. In this case, input is clamped at the remote SP lower or
upper limit values, and the RSP" LED blinks.

• If the output function RSP input error" is assigned for when an outof

range remote SP is input, the RSP input error" output is turned ON.
Control output also switches to the setting of the MV at PV error"
parameter.

• Set the upper limit value in the remote SP upper limit" parameter and

the lower limit value in the remote SP lower limit" parameter (option
mode).

the remote SP monitor" parameter.

• When the local SP is switched to from the remote SP when the SP track

ing function is enabled, the local SP is changed so that the remote SP
value is held at the SP value used immediately before switching.
To use the SP tracking function, set the SP tracking" parameter to

(3) When the local SP is switched to, the set point becomes LSP2" if the

SP tracking function is enabled. If this function is disabled, the SP

will be switched to LSP1".

• When the local SP is switched to the remote SP, the SP ramp will operate

if the SP ramp function is enabled.

• During autotuning, remote SP input is not accepted. Autotuning is

executed on the set point at the start of autotuning.

4.4 How to Use the Heater Burnout Alarm

4.4 How to Use the Heater Burnout Alarm

• On a standard type controller, the HBA (heater burnout alarm) function

can be used only when the assignment destination of the output function
control output (heat)" is set to pulsed output.

• When using the HBA function, assign output function heater burnout

(HB) alarm" to control output 1 or 2, auxiliary outputs 1 or 2.

• Heater burnout detection works as follows.

(1) Connect the current transformer (CT) to terminal Nos.15 and 17, and

insert the heater lead through the CT hole.
(2) When current flows through this lead, the current transformer gener

ates AC current proportional to the current value. The E5EKDRT

measures this AC current to calculate the current flowing to the

heater.
(3) If heater is burned out, the current measured at the current trans

former decreases. This value is compared with the value set as the

heater burnout set value and is output as the heater burnout alarm.

• Set the heater burnout set value in the heater burnout alarm" parame

ter. To check the current value of the current transformer, use the
heater current monitor" parameter.

• When you are not using the HBA function, set the heater burnout

alarm" parameter to 0.0 (disabled)".

• When the HBA latch function is set to ON", the heater burnout alarm

is held until either of the following measures is taken:

a Set the heater burnout set value to 0.0A" (default).
b Reset the controller.

(Turn the controller’s power OFF then back ON again.)

• To enable the HBA latch function, set the HBA latch" parameter to

ON".

• Turn the heater power supply ON at the same time as or before turning

the E5EKDRT power supply ON. If the heater power supply is turned
ON after turning the E5EKDRT power supply On, the heater burnout
alarm is output.

• Control is continued even when the heater burnout alarm is output.

(That is, the controller attempts to control the heater as if the heater
burnout alarm has not occurred.) So, remedy the condition such as
repairs which are caused by the heater burnout alarm.

• The heater burnout alarm is detected only if the control output is contin

uously ON for 190 ms or more.

• The rated current value may sometimes differ slightly from the actual

current value flowing to the heater. Check the current value in an actual
operating status in the heater current monitor" parameter.

• If there is little difference between the current in a normal status and the

current in a burnout status, detection may become unstable. On a heater
of current 10.0 A or less, maintain a difference of 1.0 A or more. On a
heater of current 10.0 A or more, maintain a difference of 2.5 A or more.

• Heater burnout alarm function cannot be used when controlling the

heater by a phase control method or by a cycle control method. Also,
3phase heaters cannot be used.

When detecting heater burnout on a 3phase heater, use the K2CUFVVAVGS
(with gate input terminal). (For details, see the respective data sheet.)

• Calculate the set value by the following formule:

• Set the current value at burnout when two or more heaters are con

nected to the CT to the value at the time that the heater having the small
est current value burns out (the value when one of the heaters burns out
with all heaters at the same current).

• Make sure that the following condition is satisfied:

Heater of current 10.0 A or less
Current value at normal operation − current value at heater burn
out y 1 A
When resultant current is less than 1 A, detection is unstable.
Heater of current 10.0 A or more
Current value at normal operation − current value at heater burn
out y 2.5 A
When resultant current is less than 2.5 A, detection is unstable.

• The setting range is 0.1 to 49.9 A. Heater burnout is not detected when

the setting is 0.0" or 50.0". When the setting is 0.0", the heater burn
out alarm is set to OFF", and when the setting is 50.0", the heater
burnout alarm is set to ON".

• Set the total current value at normal heater operation to 50 A or less.

When set to 55.0 A or more, [ ] is displayed in the heater current
monitor" parameter.

4.5 LBA

4–11

4.5 LBA

• The LBA function can be used only when assigned as an output. Also, the

LBA function does not work when a memory error or A/D converter
error results.

• LBA (Loop Break Alarm) is a function for judging that an error has

occurred somewhere on the control loop and outputting an alarm when
the process value does not change with the manipulated variable at a
maximum or minimum state. Accordingly, the LBA function can be used
as a means for detecting a malfunctioning control loop.

• Normally, when output is set to maximum or minimum, the process

value rises or falls after the dead time has elapsed. LBA is output if the
process value does not change in the predicted direction after a fixed
amount of time has elapsed. This fixed amount of time is the LBA detec
tion time."

• LBA operation sometimes becomes unstable when the process value

fluctuates considerably due to the control characteristics. The LBA
detection width is provided so that changes with respect to output can
be correctly detected. Changes smaller than the detection width due to
LBA detection timing are not regarded as changes.

• The following example describes what happens when a heater burnout

at maximum output.

LBA detection time

• LBA judgment is carried out at each LBA detection time from the point

of maximum output. In above figure, the process value (PV) is changing
greatly at the 1st judgment timing, so LBA remains OFF.

• At the 2nd judgment timing, the process value increases as indicated by

the broken line of the process value is normal. This means that the
change width exceeds the LBA detection width, and LBA output remains
OFF.

• If the heater burns out at the point shown in the above figure, the process

value decreases." Accordingly, it is judged that the process value is not
changing in the increasing direction" at the 2nd judgment timing and
the LBA output becomes ON.

heating and cooling control).

• If the optimum LBA detection time cannot be obtained by autotuning,

set the time in the “LBA detection time" parameter (level 2 mode).

• Calculate the LBA detection time as follows:

(1) Set output to maximum.
(2) Measure the time it takes for the input change width to reach the LBA

detection width (default: 0.2 % fullscale).
(3) Take a value twice that of the measurement time as the LBA detection

time.

SP setting upper limit

SP setting lower limit

• Limits the upper and lower limits of the set point. When the set point exceeds the set

tings of the SP setting upper limit" and SP setting lower limit" parameters, the
E5EKDRT controller regards the settings of the Set point upper limit" and Set
point lower limit" parameters as the set points.

• When the input type or temperature unit is changed, the values will be forceset to

the sensor’s upper and lower limits.

• During temperature input, the decimal point position is dependent on the currently

selected sensor, and during analog input on the results of scaling.

Parameter Setting Range

Unit Default

SP setting upper limit SP setting lower limit +1 to scaling upper limit EU 1300
SP setting lower limit Scaling lower limit to SP setting upper limit -1 EU -200

During temperature input, the range becomes the range of use of the selected sensor
instead of the scaling upper and lower limit values.
