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 E5EK. (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 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. T hese 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. The 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 an d 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.

1.2 Input and Output
F Event input
JOutput
When using event input, add on the input unit (E53-CKB).
You can select from the following four event inputs:
Multi-SP
Run/Stop
Auto/Manual
SP mode
The E5EK supports the following five outputs.
Control output 1
Control output 2
Auxiliary output 1
Auxiliary output 2
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 E5EK do not operate for five seconds
after the E5EK is turned ON.
F Output assign-
ments
The E5EK 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 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 p age, “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.

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.

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
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 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 temp erature 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.
1.5 About Calibration
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 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.
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.

3.2 Setting Input Specifications
JInput type
JScaling
• Set the type No. (0 to 21) in the “input type” parameter. The factory
setting is “2: K1 (thermocouple).”
• For details on input types and setting ranges, see page 5-26.
• When the voltage input and current input are selected, scaling
matched to the control is required.
• The “scaling upper limit”, “scaling lower limit” and “decimal point”
parameters (setup mode) are use for scaling.
• The “scaling upper limit” parameter sets the physical quantity to be
expressed 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 scaling example of 4 to 20 mA input. After
scaling, the humidity can be directly read. In this case, the “decimal
point” parameter is set to “1”.

• When temperature input is selected, scaling is not required. This is
because input is treated as the “temperature” as it is matched to the
input type. However, note that the upper and lower limit values of the
sensor can be shifted. For example, if both the upper and lower limit
values are shifted by 1.2_C, the process value (before shift) is regarded
as 201.2_C after shift when input is 200_Cbeforeshift.
• To set input shift, set shift values in the “input shift upper limit” and
“input shift lower limit” parameters (level 2 mode).

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 output is not assigned. For details on heating and cooling control, see 4.1 Selecting the Control Method (page 4-2).

control output 2 = Alarm 1
auxiliary output 1 = Alarm 2
auxiliary output 2 = Alarm 3.

“control output 2 assignment”, “aux output 1 assignment” and “aux

• “Direct operation” (or normal operation) refers to control where the
manipulated variable is increased according to the increase in the
process value. Alternatively, “reverse operation” refers to control
where the manipulated variable is decreased according to the decrease
in the process 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 operat ion” in a cooling control
system.
• Direct/reverse operation is set in the [

JControl period
• 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
theoutputunitisrelay.
• 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.

• “Standby sequence” is a function for unconditionally turning alarm
output 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,”
generally 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 belo w the alarm value.

execution ≧ 10% full-scale
• AT (auto-tuning) cannot be executed while operation is canceled or
during ON/OFF control.
• When you execute auto-tuning, the optimum PID parameters 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” parameter (level 1 mode).
• During heating and cooling control and with position-proportional
type, only 100%AT can be executed. (So, [
](40%AT)willnotbe
displayed.)
• To cancel AT execution, specify [
](“ATcancel”).
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 to execute
compared with 100%AT.
The timing by which limit cycles are generated varies according to
whether or not the deviation (DV) at the start of AT execution is 10%
full-scale or less.

About PID Parameters
When control characteristics are already known, the PID parameters can be set
directly to adjust control.
PID parameters are set in the “proportional band” (P), “integrated time” (I) and
“derivative time” (D) parameters (level 1 mode).
For details on the setting ranges of these parameters, see chapter 5 Level 1 Mode

F Dead band
• When heating and cooling control is selected, the “deadband” and
“cooling coefficient” parameters can be used.
The dead band is set with the set point as its center . The dead band
width is the set value of the “dead band” parameter (level 1 mode). Setting a positive value produces a dead band, while setting a negative
value produces an overlap band.

If the heating and cooling characteristics of the control target greatly
differ, 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 b etween
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
variable at the cooling side is treated as a negative value for the sake
of convenience. When the manipulated variable at STOP is a negative
value, the manipulated variable is output to only the cooling side, and
when a positive 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.

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 input type, temperature unit and scaling (sensor) range are
changed, set point limiter is forcibly reset to the scaling (sensor) range.

• Switch the parameter settings for each of the run/stop, remote/local
and SP modes.
• The switching operation of auto/manual is the same as that of the
key.
• There is no order of priority in event input and key operations. However, run/stop or auto/manual event inputs must be set to either of
ON or OFF. So, parameters will always follow event input even if you
try to switch settings by key operation.

F Run/Stop
F Auto/Manual
F SP mode
• When event input is set to “ON”, controller operation is stopped and
the “STOP” LED lights. The content of event input is reflected in the
“run/stop” parameter (level 0 mode).
• When event input is set to “ON”, the controller is switched for
manual operation, and the “MANU” LED lights.
• Turn event input ON/OFF while the controller is ON.
• This function is enabled only when the “SP mode enable” parameter
(option mode) is set to “ON”.
• When event input is set to “ON”, the remote SP (RSP) is taken as the
set point, and the “RSP” LED lights. When event input is set to
“OFF”, the local SP (LSP) is taken as the set point. The content of
event input is reflected in the “SP mode” parameter (level 2 mode).
For details on RSP/LSP, see 4.4 How to Use the Remote SP (page
4-11).

4.4 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”.

JScaling
F Relationship with
set point limiter
• 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-ofrange 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 outof-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).

• When the “Set point upper limit” or “Set point lower limit” parameters are changed, the remote SP upper-and lower-limit values are forcibly changed to the set point upper-and lower-limit values. The following example shows how the remote SP upper-and lower-limit
values are changed when the set point upper limit value is changed

• The set point held internally by the E5EK controller is referred to as
the “local SP (LSP).”
• If the multi-SP function is enabled, set points 0 to 3 are enabled for
use as the local SP.
• Use the “SP mode” parameter to switch between the remote SP and
local SP. When the SP mode parameter is set to “

the “RSP” LED lights. When the SP mode parameter is set to
“

JSP tracking
• IntheremoteSP mode,theremoteSPcanbe monitoredontheNo.2
display for PV/SP. In the local SP mode, the remote SP can be monitored in the “remote SP monitor” parameter.
• When the local SP is switched to from the remote SP when the SP
tracking 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
“ON”.
• The following figure shows how SP tracking works when the SP mode
is switched.

conditions
(1) When the remote SP is switched to when the set point is “LSP1”,
the SP is switched to “RSP2”.
(2) The SP shifts according to remote SP input.
(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.
• When the SP function is set to “ON”, the “SP mode” parameter is forcibly changed to [
] and the local SP is taken as the set point.
• During auto-tuning, remote SP input is not accepted. Auto-tuning is
executed on the set point at the start of auto-tuning.
• Remote SP is not subject to the standby sequence reset conditions.

4.5 How to Use the Heater Burnout Alarm
4.5 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 auxiliary outputs 1 or 2.
JHeater burnout
detection
To E5EK
CT terminal
CT
Heater wire
F HBA
latch/release
• 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 gen-
erates AC current proportional to the current value. The E5EK
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”
parameter. 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 “0.0”.
b Reset the controller.
(Turn the controller’s power OFF then back O N again.)
• To enable the HBA latch function, set the “HBA latch” parameter to
“ON”.
JOperating
conditions
• Turn the heater power supply ON at the same time as or before turning the E5EK power supply ON. If the heater p ower supply is turned
ON after turning the E5EK 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
continuously 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 metho d or by a cycle control method. Also,
3-phaseheaterscannotbeused.
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.)
4-- 13
CHAPTER 4 APPLIED OPERATION
JHow to calculate
the heater burnout set value
• Calculate the set value by the following formula:
Set value =
(current value at normal operation + current value at burnout)
2
• Setthecurrentvalueatburnoutwhentwoor moreheatersareconnected to the CT to the value at the time that the heater having the
smallest 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
burnout ≧ 1A
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
burnout ≧ 2.5 A
When resultant current is less than 2.5 A, detection is unstab le.
• 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 burnout 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 cur-
rent monitor” parameter.

4.6 LBA
4.6 LBA
• The LBA (Loop Break Alarm) function can be used only on standard
type controllers.
• 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.
F LBA detection
time
F LBA detection
width
F LBA detection
example
• 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 detection 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.

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.
LBA=ON

F Determining the

time
• The LBA detection time is automatically set by auto-tuning (except in
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) Measurethetimeittakesfortheinputchangewidthtoreachthe
LBA detection width (default: 0.2 % full-scale).
(3) Take a value twice that of the measurement time as the LBA detec-
tion time.

MV change rate limit
• The “MV upper limit” and “MV lower limit” parameters set the upper and lower
limits of the manipulated variable. When the manipulated variable calculated by
the E5EK controller is outside of the upper-and lower-limit range, the upper limit
or lower limit set to these parameters is output, respectively.
However, note that these parameters are disabled during position-proportional
control.
• The “MV change rate limit” parameter sets the maximum permissible change
width per second of the manipulated variable (On the position-proportional control, valve, opening). If a change in the manipulated variable (On the position-proportional control, valve, opening) causes this parameter setting to be exceeded, the
calculated value is reached while changing the value by the per-second value set in
this parameter.
This function is disabled when the set value is “0.0”.
