PayAttention t o 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 E5AK. (Ensure sufficient space around the controller

to allow heat radiation.)

F Use a voltage (A C100-240V

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 o r common wiring with high voltage sources and power lines carrying
large currents.

· Using separatingpipes, duct,and shielded line is also useful in protecting thecontroller,
and its lines form inductive noise.

F Allow as much space as possible between the controller and devices that generate a pow-

erful, 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 (espe-

cially 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 temperaturemust 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 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.

ments

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

Multi-SP

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 functionsof the E5AK do not operate for five secondsaf-

ter the E5AK is turned ON .

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 con ­troller (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.

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 o n the RS-232C interface, add
on the communications unit (E53-AK01).

When using the communicationsfunction on the RS -422 interface, add on
the communications unit (E53-AK02).

When using the communicationsfunction on the RS -485 interface, add on
the communications unit (E53-AK03).

1--10

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 providedfor user to calibrate temperatureinput, analoginput
(voltage, current) and transfer output.
Also, note thatcalibration data is updatedto the latestvalue each timethe

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 regis-

tered 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.

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 theupper limit valueof input, and the “scalinglower 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”.

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 val­uesareshiftedby1.2_C, the process value (before shift) is regarded as

201.2_C after shift when input is 200_Cbeforeshift.

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

· “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 pro ­cess value.
For example, when the process value (PV), is lower than the set point
(SP), in a heating control system, the manipulatedvariable increasesby
the difference between the PV and SP values.
Accordingly, this becomes “reverse operation” in a heating control syste m.
Alternatively, this becomes “direct operation” in a cooling control system.

· Direct/reverse operation is set in the [

· 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.

· 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

· For example, when the alarm type is set to “deviation lower limit,” gener-
ally the process value i s within the alarm range, and alarm output
become ON as it is as the process value when the power is turned ON is
smallerthan 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.

If the heating and cooling characteristics of the control target greatly dif­fer, preventing satisfactory control characteristics from being obtained by
the same PID parameters, adjustthe 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

· However, note that in heatingand cooling control,the manipulatedvari­ableat thecooling sideis treatedas a negativevalue for the sakeof conve­nience. When the manipulated variable at STOP is a negative value, the
manipulated variable is outputto 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.

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 E5AK is outside of the

4.3 How to Use Event Input

· When using event input, mount the option unit (E53-AKB). Up to two
E53-AKB units can be mounted on the E5AK, and two event inputs can
be used for each E53-AKB unit.

E53-AKB × 1unit :2eventinputs
E53-AKB × 2 units : 4 event inputs

· Event inputs can be switched up to 100,000 times.

JEvent input

assignments

· You can choose from the following five event input functions:

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

· In the case of the multi-SP function, the number of event inputs (event
input 1 or 2) set in the “multi-SPfunction” parameter (option mode) are
used. When four event inputs are used, the multi-SP function is auto­matically assigned to event inputs 1 and 2 for the designated number.
When two event inputs are used, the multi-SP function is automatically
assigned to event inputs 3 and 4 for the designated number.

· Other functions are assigned to event inputs 1 to 4 not used for the mul­ti-SP function according to the setting of the “event input assignme nt 1 to
4” parameters (option mode). However , note that “event input assignment
1/2” parameters cannot be used when only one unit of the E53-AKB is
installed.

· Set points 0 to 3 are set as the set point according to event input. How­ever, note that these parameters can not be set when the multi-SP func­tion is not selected. The following table shows the relationship between
event inputs and set points 0 to 3.

* When using 2 event inputs, the multi-SP function is assigned to event

inputs 3 and 4.

· When you have changed the set point in the PV/SP display, the set point
of the currently selected is also simultaneously changed.

· When you have switched between set point 0 to 3, the SP ramp function
works if the SP ramp function is enabled. The following example shows

· The switching operation of auto/manual is the same as that of the
key.

· Thereis no order of priority in event input and key operations. However,

· When eventinput is set to “ON”, controller operation is stopped and the
“STOP” LED lights. The content of event input is reflected in the “run/

· This function is supported only when E53-AK01/02/03, the option unit
for serial communications, is installed.

· When event input is set to “ON”, parameters can be written only by
using the communications function, and the “RMT” LED lights. The

· 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/

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-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-of­range 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 poimt upper-and lower-limit values. The following

· In the remote SP mode, the remote SP can be monitored on the No.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 switchedto 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

4.5 How to Use the Heater Burnout Alarm

· On a standardtype controller, the HBA (heater burnout alarm) function
can be usedonly when the assignment destination of theoutput function
“control output (heat)” is set to pulsed output.

(HB) alarm” to auxiliary outputs 1 or 2.

JOperating

conditions

· Heater burnout detection works as follows.

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

insert the heater lead through the CT hole.

(2) When current flows through thislead, the current transformergener-

ates AC current proportional to the current value. The E5AK 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 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 E5AK power supply ON. If the heater power supply is turned ON
after turning the E5AK 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 method 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 nby the following formule:

Set value =

(current value at normal operation + current value at burnout)

2

· Set the current value at burnout when two or more heaters are con­nected 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 heatersburns 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 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 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 current

monitor” parameter.

4.6 LBA

· The LBA (Loop Break Alarm) function can be used only on standard
type controllers.

· The LBA function can be usedonly when assignedas 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
maximumor minimum state.Accordingly, the LBA function can be used
as a means for detecting a malfunctioning control loop.

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
amountof time has elapsed. This fixed amount of time is the “LBAdetec­tion 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 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. T his 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 abovefigure,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.

MV change rate limit

· The “MV upper limit” and “MV lower limit” parametersset the upper and lower lim-

its of the manipulated variable. When the manipulated variable calculated by the
E5AK 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”.
