Precautions for Safe Use

Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse affects on
the performance and functions of the product. Not doing so may occasionally result in unexpected events.

1) The product is designed for indoor use only. Do not use the product outdoors or in any of the following
locations.

• Places directly subject to heat radiated from heating equipment.

• Places subject to splashing liquid or oil atmosphere.

• Places subject to direct sunlight.

• Places subject to dust or corrosive gas (in particular, sulfide gas and ammonia gas).

• Places subject to intense temperature change.

• Places subject to icing and condensation.

• Places subject to vibration and large shocks.

2) Use and store the Digital Controller within the rated ambient temperature and humidity.
Gang-mounting two or more Digital Controllers, or mounting Digital Controllers above each other may

cause heat to build up inside the Digital Controllers, which will shorten their service life. In such a case,
use forced cooling by fans or other means of air ventilation to cool down the Digital Controllers.

3) To allow heat to escape, do not block the area around the product. Do not block the ventilation holes on
the product.

4) Be sure to wire properly with correct polarity of terminals.

5) Use specified size (M3.5, width 7.2 mm or less) crimped terminals for wiring. To connect bare wires, use
stranded or solid copper wires with a gage of AWG24 to AWG14 (equal to cross-sectional areas of 0.205

2

to 2.081 mm
terminals can be inserted into a single terminal.

6) Do not wire the terminals which are not used.

7) To avoid inductive noise, keep the wiring for the Digital Controller's terminal block away from power
cables carry high voltages or large currents. Also, do not wire power lines together with or parallel to
Digital Controller wiring. Using shielded cables and using separate conduits or ducts is recommended.
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).
When a noise filter is used at the power supply, first check the voltage or current, and attach the noise
filter as close as possible to the Digital controller.
Allow as much space as possible between the Digital Controller and devices that generate powerful high
frequencies (high-frequency welders, high-frequency sewing machines, etc.) or surge.

8) Use this product within the rated load and power supply.

9) Make sure that the rated voltage is attained within two seconds of turning ON the power using a switch or
relay contact. If the voltage is applied gradually, the power may not be reset or output malfunctions may
occur.

10) Make sure that the Digital Controller has 30 minutes or more to warm up after turning ON the power
before starting actual control operations to ensure the correct temperature display.

11) When using self-tuning, turn ON power for the load (e.g., heater) at the same time as or before supplying
power to the Digital Controller. If power is turned ON for the Digital Controller before turning ON power for
the load, self-tuning will not be performed properly and optimum control will not be achieved.

12) A switch or circuit breaker should be provided close to this unit. The switch or circuit breaker should be
within easy reach of the operator, and must be marked as a disconnecting means for this unit.

13) Always turn OFF the power supply before pulling out the interior of the product, and never touch nor apply
shock to the terminals or electronic components. When inserting the interior of the product, do not allow
the electronic components to touch the case.

14) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.

xii

15) Design system (control panel, etc.) considering the 2 second of delay that the controller’s output to be set
after power ON.

16) The output may turn OFF when shifting to certain levels. Take this into consideration when performing
control.

17) The number of EEPROM write operations is limited. Therefore, use RAM write mode when frequently
overwriting data during communications or other operations.

18) Always touch a grounded piece of metal before touching the Digital Controller to discharge static
electricity from your body.

19) Do not remove the terminal block. Doing so may result in failure or malfunction.

20) Control outputs that are voltage outputs are not isolated from the internal circuits. When using a grounded
thermocouple, do not connect any of the control output terminals to ground. (Doing so may result in an
unwanted circuit path, causing error in the measured temperature.)

21) When replacing the body of the Digital Controller, check the condition of the terminals. If corroded
terminals are used, contact failure in the terminals may cause the temperature inside the Digital Controller
to increase, possibly resulting in fire. If the terminals are corroded, replace the case as well.

22) Use suitable tools when taking the Digital Controller apart for disposal. Sharp parts inside the Digital
Controller may cause injury.

23) Check the specifications of the Control Output Unit and assemble it correctly.

24) When mounting the Control Output Unit, read and follow all relevant information in the product catalogs
and manuals.

25) When applying Lloyd's standards, install the Digital Controller according to the requirements given in
Shipping Standards.

 Service Life

Use the Digital Controller within the following temperature and humidity ranges:
Temperature: −10 to 55°C (with no icing or condensation), Humidity: 25% to 85%

If the Controller is installed inside a control board, the ambient temperature must be kept to under
55°C, including the temperature around the Controller.

The service life of electronic devices like Digital Controllers is determined not only by the number of
times the relay is switched but also by the service life of internal electronic components. Component
service life is affected by the ambient temperature: the higher the temperature, the shorter the service
life and, the lower the temperature, the longer the service life. Therefore, the service life can be
extended by lowering the temperature of the Digital Controller.

When two or more Digital Controllers are mounted horizontally close to each other or vertically next to
one another, the internal temperature will increase due to heat radiated by the Digital Controllers and
the service life will decrease. In such a case, use forced cooling by fans or other means of air ventila­tion to cool down the Digital Controllers. When providing forced cooling, however, be careful not to cool
down the terminals sections alone to avoid measurement errors.

 Ambient Noise

To avoid inductive noise, keep the wiring for the Digital Controller's terminal block wiring away from
power cables carrying high voltages or large currents. Also, do not wire power lines together with or
parallel to Digital Controller wiring. Using shielded cables and using separate conduits or ducts is rec­ommended.
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). When a noise filter is used at the power supply, first check the voltage or current, and attach the
noise filter as close as possible to the Digital Controller.
Allow as much space as possible between the Digital Controller and devices that generate powerful
high frequencies (high-frequency welders, high-frequency sewing machines, etc.) or surge.

xiii

 Ensuring Measurement Accuracy

When extending or connecting the thermocouple lead wire, be sure to use compensating wires that
match the thermocouple types.

When extending or connecting the lead wire of the platinum resistance thermometer, be sure to use
wires that have low resistance and keep the resistance of the three lead wires the same.

Mount the Digital Controller so that it is horizontally level.

If the measurement accuracy is low, check to see if input shift has been set correctly.

 Waterproofing

The degree of protection is as shown below. Sections without any specification on their degree of pro­tection or those with IP0 are not waterproof.

Front panel: IP66
Rear case: IP20, Terminal section: IP00

xiv

Precautions for Operation

1) It takes approximately two seconds for the outputs to turn ON from after the power supply is turned ON.
Due consideration must be given to this time when incorporating Digital Controllers into a control panel or
similar device.

2) Make sure that the Digital Controller has 30 minutes or more to warm up after turning ON the power
before starting actual control operations to ensure the correct temperature display.

3) When executing self-tuning, turn ON power for the load (e.g., heater) at the same time as or before
supplying power to the Digital Controller. If power is turned ON for the Digital Controller before turning ON
power for the load, self-tuning will not be performed properly and optimum control will not be achieved.
When starting operation after the Digital Controller has warmed up, turn OFF the power and then turn it
ON again at the same time as turning ON power for the load. (Instead of turning the Digital Controller OFF
and ON again, switching from STOP mode to RUN mode can also be used.)

4) Avoid using the Controller in places near a radio, television set, or wireless installing. The Controller may
cause radio disturbance for these devices.

Shipping Standards

The E5N-H Digital Controllers comply with Lloyd's standards. When applying the standards, the following
installation and wiring requirements must be met in the application.

 Application Conditions

1) Installation Location

The E5N-H Digital Controllers comply with installation categories ENV1 and ENV2 of Lloyd's stan­dards. They must therefore be installed in a location equipped with air conditioning. They cannot be

I/O Configuration and Main Functions Section 1-2

Control Outputs • A control output can be a relay output, voltage output (for driving SSR),

linear voltage output, SSR output, or current output, depending on the
model.

• With the E5CN-H2, auxiliary output 2 is used as control output
(cooling) when heating/cooling control is selected. (It is also possible to
allocate a different output.) Therefore, use auxiliary output 1 if an auxiliary
output is required while using heating/cooling control.

Alarms • Set the alarm type and alarm value or the alarm value upper and lower

limits.

• If necessary, a more comprehensive alarm function can be achieved by
setting a standby sequence, alarm hysteresis, auxiliary output close in
alarm/open in alarm, alarm latch, alarm ON delay, and alarm OFF delay.

• If the Input Error Output parameter is set to ON, the output assigned to
alarm 1 function will turn ON when an input error occurs.

• If the Remote SP Input Error Output parameter is set to ON, the output
assigned to the alarm 1 function will turn ON when an input error occurs.

Control Adjustment • Optimum PID constants can be set easily by performing AT (auto-tuning)

or ST (self-tuning).

Event Inputs • With the E53-CNBN2 for the E5CN-H (for two event inputs), the

E5AN/EN-HBM-500 for E5AN/EN-H (for two event inputs) or the
E5AN/EN-HBM-500 with the E53-AKB for the E5AN/EN-H (for four
event inputs), the following functions can be executed using event inputs:
switching banks, switching RUN/STOP, switching between automatic and
manual operation, starting/resetting the program, inverting direct/reverse
operation, switching SP modes, 100% AT execute/cancel, 40% AT exe­cute/cancel, setting change enable/disable, communications writing
enable/disable and canceling the alarm latch.

1-3 Setting Level Configuration and Key Operations

Parameters are divided into groups, each called a level. Each of the set val­ues (setting items) in these levels is called a parameter. The parameters on
the E5CN/AN/EN-H are divided into the following 9 levels.

When the power is turned ON, all of the display lights for approximately one
second.

Note (1) Your can return to the operation level by executing a software reset.

(2) You cannot move to other levels by operating the keys on the front panel

from the calibration level. You must turn OFF the power supply.

(3) From the manual control level, key operations can be used to move to the

operation level only.

Protect Level • To switch to the protect level from the operation level, the adjustment

level, bank setting level, or PID setting level, simultaneously hold down
the O and M Keys for at least 3 seconds. (See note.) This level is for pre­venting unwanted or accidental modification of parameters. Protected lev­els will not be displayed, and so the parameters in that level cannot be
modified.

Note The key pressing time can be changed in Move to Protect Level pa-

rameter (advanced function setting level).

Operation Level • The operation level is displayed when the power is turned ON. You can

move to the protect level, initial setting level, or adjustment level from this
level.

• Normally, select this level during operation. While operation is in progress,
items such as the PV and manipulated variable (MV) can be monitored,
and the set points, alarm values, and alarm upper and lower limits can be
monitored and changed.

Adjustment Level • To move to the adjustment level, press the O Key once (for less than 1 s).

• This level is for entering set values and offset values for control. In addi­tion to AT (auto-tuning), communications write enable/disable switching,
hysteresis settings, SP settings, and input offset parameters, it includes
HB alarm, HS alarm, OC alarm, and PID constants. From the adjustment
level, it is possible to move to the bank setting level, initial setting level, or
protect level.

Bank Setting Level • To move to the bank setting level from the adjustment level, press the O

Key once (for less than 1 s).

• This level is used to input parameters such as set points, alarm values,
and PID set numbers. From the bank setting level, it is possible to move to
the PID setting level, the initial setting level, or the protect level.

PID Setting Level • To move to the PID setting level from the bank setting level, press the O

Key once (for less than 1 s).

• This level is used to input parameters such as the PID values for each PID
set, MV upper and lower limits, and automatic selection range upper and
lower limits. From the PID setting level, it is possible to move to the opera­tion level, the initial setting level, or the protect level.

12

Setting Level Configuration and Key Operations Section 1-3

Monitor/Setting Item Level • To switch to the monitor/setting item level, press the PF Key from the

operation level, adjustment level, bank setting level, or PID setting level.
The contents set for monitor/setting items 1 to 5 can be displayed. You
can move from the monitor/setting item level to the operation level or initial
setting level. (E5AN/EN-H only.)

Manual Control Level • When the O Key is pressed for at least 3 seconds from the operation

level's auto/manual switching display, the manual control level will be dis­played. (The MANU indicator will light.)

• When the PF Setting is set to A-M (auto/manual) and the PF Key is
pressed for more than one second from the operation level, adjustment
level, bank setting level, or PID setting level the manual control level will
be displayed. (E5AN/EN-H only.)

• This is the level for changing the MV in manual mode.

• To return to the operation level, press the O Key for at least one second.
It is also possible to return to the operation level by pressing the PF Key
for more than one second when the PF Setting is set to A-M.

Initial Setting Level • To move to the initial setting level from the operation level, the adjustment

level, bank setting level, PID setting level, or monitor/setting item level,
press the O Key for at least 3 seconds. The PV display flashes after one
second. This level is for specifying the input type and selecting the control
method, control period, setting direct/reverse operation, setting the alarm
types, etc. You can move to the advanced function setting level or commu­nications setting level from this level. To return to the operation level,
press the O Key for at least one second. To move to the communications
setting level, press the O Key for less than one second.
(When moving from the initial setting level to the operation level, all the
indicators will light.)

Note Pressing the O Key for at least 3 seconds in the operation level's

auto/manual switching display will move to the manual control level,
and not the initial setting level.

• From the advanced function setting level, it is possible to move to the cali­bration level or to the initial setting level.

• This level is for setting the automatic display return time and standby
sequence, and it is the level for moving to the user calibration and other
functions.

• To move to the communications setting level from the initial setting level,
press the O Key once (for less than 1 s). When using the communica­tions function, set the communications conditions in this level. Communi­cating with a personal computer (host computer) allows set points to be

each time the M Key is pressed. (In the calibration level, however,
parameters cannot be changed in reverse order.) For details, refer to
SECTION 5 Parameters.

1-3-2 Saving Settings

1-4 Communications Function

• If you press the M Key at the final parameter, the display returns to the
top parameter for the current level.

• To change parameter settings, specify the setting using the U or D Key,
and either leave the setting for at least two seconds or press the M Key.
This saves the setting.

• When another level is selected after a setting has been changed, the con­tents of the parameter prior to the change is saved.

• When you turn the power OFF, you must first save the settings (by press­ing the M Key). The settings are sometimes not changed by merely
pressing the U or D Keys.

The E5CN/AN/EN-H Digital Controllers are provided with a communications
function that enables parameters to be checked and set from a host computer.
If the communications function is required, use a model that has that function
(E5CN-HM-500 with an E53-CN01N2 or E53-CN03N2, E5AN-H/EN­HM-500 with an E53-EN01, E53-EN02, or E53-EN03). For details on the
communications function, see the separate Communications Manual
Advanced Type. Use the following procedure to move to the communications
setting level.

• The E5CN-H voltage output (for driving SSR) is not electrically isolated
from the internal circuits. When using a grounding thermocouple, do not
connect any of the control output terminals to the ground. (If a control out­put terminal is connected to the ground, errors will occur in the measured
temperature as a result of leakage current.) E5AN/EN-H voltage outputs
(for driving SSR), however, are functionally isolated from the internal cir­cuits.

• If high levels of noise or surge are imposed between the output terminals
of an SSR output, short-circuit faults may occasionally occur. If the output
becomes permanently shorted, there is the danger of fire due to overheat­ing of the heater. Design safety into the system, including measures to
prevent excessive temperature rise and spreading of fire.

• Control output 2 of the E5CN-H is a voltage output (for driving SSR) only,
and outputs across terminals 11(+) and 12(-), or 14(+) and 15(-).

• Control output 1 (voltage output for driving SSR) and control output 2
(voltage output for driving SSR) are not isolated.

• If high levels of noise or surge are imposed between the output terminals
of an SSR output, short-circuit faults may occasionally occur. If the output

• On the E5AN/EN-H2-500, auxiliary output 1 (SUB1) is output across
terminals 9 and 10, auxiliary output 2 (SUB2) is output across terminals 7

• When the Input Error Output parameter is set to ON, the output assigned
to the alarm 1 function turns ON when an input error occurs.

• If the Remote SP Input Error Output parameter is set to ON, the output
assigned to the alarm 1 function will turn ON when an RSP input error
occurs.

• When the HB alarm, HS alarm, or heater overcurrent alarm is used with
the E5CN-H (with E53-CNH/HHN2), alarms are output to the output
assigned to the alarm 1 function.

• When the HB alarm, HS alarm, or heater overcurrent alarm is used with
the E5AN-H/EN-H, alarms are output across terminals 9 and 10.

• On the E5CN-H, when heating/cooling control is used, auxiliary output 2
becomes control output (cooling).

• On the E5AN-H and E5EN-H, when heating/cooling control is used, con­trol output 2 becomes the control output (cooling).

• For models that have a heater burnout alarm, an OR of the alarm 1 func­tion and the HB alarm, HS alarm, or heater overcurrent alarm is output. If
the alarm 1 function is to be used for HB alarm only, set the alarm 1 type
to 0 (i.e., do not use alarm 1 function).

3-4 Selecting PID Control or ON/OFF Control

Two control methods are supported: 2-PID control and ON/OFF control.
Switching between 2-PID control and ON/OFF control is executed by means
of the PID ON/OFF parameter in the initial setting level. When this parameter
is set to pid, 2-PID control is selected, and when set to onoff, ON/OFF con­trol, is selected. The default is pid. ON/OFF control is not displayed for posi-
tion-proportional models.

2-PID Control PID control is set by AT (auto-tuning), ST (self-tuning), or manual setting.

For PID control, set the PID constants in the Proportional Band (P), Integral
Time (I), and Derivative Time (D) parameters.

ON/OFF Control In ON/OFF control, the control output is turned ON when the process value is

lower than the current set point, and the control output is turned OFF when
the process value is higher than the current set point (reverse operation).

• Set the output periods (control periods). Though a shorter period provides
better control performance, it is recommended that the control period be
set to 20 seconds or longer for a relay output to preserve the service life
of the relay. After the settings have been made in the initial setup, readjust
the control period, as required, by means such as trial operation.

• Set the control periods in the Control Period (Heating) and Control Period
(Cooling) parameters in the initial setting level. The default is 20 seconds.

• The Control Period (Cooling) parameter is used only for heating/cooling
control.

• When the control output is used as a current output or linear voltage out­put, the Control Period settings cannot be used.

• The control period can be set for standard models only.

PV/SP

For example, when the process value (PV) is lower than the set point (SP)
in a heating control system, the manipulated variable increases according
to the difference between the PV and SP. Accordingly, reverse operation is
used in a heating control system. Direct operation is used in a cooling con­trol system, in which the operation is the opposite of a heating control sys­tem.

• Direct/reverse operation is set in the Direct/Reverse Operation parameter
in the initial setting level. The default is or-r (reverse operation).

Operating Procedure In this example, the input type, temperature unit, direct/reverse operation, and

control period (heat) parameters are checked.

■ Alarms

It will be specified in this section when an alarm must be assigned, i.e., when
an alarm must be set for the Control Output 1 or 2 Assignment parameters, or
for the Auxiliary Output 1 or 3 Assignment parameters. For example, if alarm 1
is set for the Control Output 1 Assignment parameter, then alarm 1 has been
assigned.

Assigning a work bit to either control output 1 or 2 or to auxiliary output 1 to 3
is also considered to be the same as assigning an alarm. For example, if work
bit 1 is set for the Auxiliary Output 1 Assignment parameter, then alarms 1 to 3
have been assigned.

Operating Procedure This procedure sets the following control and auxiliary output assignments.

Control output 1: Control output (heating); Control output 2: Control output
(cooling); Auxiliary output 1: Alarm 1; Auxiliary output 2: Alarm 2

3-7 Using ON/OFF Control

3-7-1 ON/OFF Control

In ON/OFF control, the control output turns OFF when the temperature being
controlled reaches the preset set point. When the manipulated variable turns
OFF, the temperature begins to fall and the control turns ON again. This oper­ation is repeated over a certain temperature range. At this time, how much the
temperature must fall before control turns ON again is determined by the Hys­teresis (Heating) parameter. Also, what direction the manipulated variable
must be adjusted in response to an increase or decrease in the process value
is determined by the Direct/Reverse Operation parameter.

• Switching between 2-PID control and ON/OFF control is performed using
the PID ON/OFF parameter in the initial setting level. When this parame­ter is set to pid, 2-PID control is selected, and when it is set to onof, ON/
OFF control is selected. The default is pid.

• ON/OFF control can be set for standard models only.

3-8 Determining PID Constants (AT, ST, Manual Setup)

3-8-1 AT (Auto-tuning)

• When AT is executed, the optimum PID constants for the set point at that
time are set automatically. A method (called the limit cycle method) for
forcibly changing the manipulated variable and finding the characteristics
of the control object is employed.

• Either 40% AT or 100% AT can be selected depending on the width of MV
variation in the limit cycle. In the AT Execute/Cancel parameter, specify
at-2 (100% AT) or at-1 (40% AT). To cancel AT, specify off (AT can­cel).

• Only 100% AT can be executed for heating and cooling control or for float­ing control for position-proportional models.

• AT cannot be executed when control has stopped or during ON/OFF con­trol.

• The results of AT are reflected in the Proportional Band (P), Integral Time
(I), and Derivative Time (D) parameters for the PID set at the time AT exe­cution starts. For details on PID sets, refer to PID Sets on page 128.

Note If ST (self-tuning) parameter is set to ON in the initial setting level, ST is exe-

cuted the first time operation is started and whenever the set point is
changed. This may cause the PID constants that were calculated by AT to be
overwritten with new values. To retain the PID constants that were calculated
by AT, turn OFF the ST parameter.

AT Operations AT is started when either at-2 (100% AT) or at-1 (40% AT) is specified for

Related parameter: ST (Self-tuning) (initial setting level)

the AT Execute/Cancel parameter. During execution, the AT Execute/Cancel
parameter on the No. 1 display flashes. When AT ends, the AT Execute/Can­cel parameter turns OFF, and the No. 1 display stops flashing.

AT Calculated Gain

The AT Calculated Gain parameter sets the gain for when PID values are cal­culated using AT. When emphasizing response, decrease the set value. When
emphasizing stability, increase the set value.

Note Disabled for 100% AT.

■ 40% AT

The width of MV variation in the limit cycle can be changed in the Limit Cycle
MV Amplitude parameter, but the AT execution time may be longer than for
100% AT. The limit cycle timing varies according to whether the deviation (DV)
at the start of auto-tuning execution is less than 10% FS.

■ 100% AT

Operation will be as shown in the following diagram, regardless of the devia­tion (DV) at the start of AT execution. To shorten the AT execution time, select
100% AT.

Note The Limit Cycle MV Amplitude parameter is disabled.

3-8-2 ST (Self-tuning)

ST (self-tuning) is a function that finds PID constants by using step response
tuning (SRT) when Digital Controller operation begins or when the set point is
changed.

Once the PID constants have been calculated, ST is not executed when the
next control operation is started as long as the set point remains unchanged.

ST (self-tuning) is enabled when the ST parameter is set to ON in the initial
setting level.

When the ST function is in operation, be sure to turn the power supply of the
load connected to the control output ON simultaneously with or before starting
Controller operation.

When executing self-tuning, turn ON power for the load (e.g., heater) at the
same time as or before supplying power to the Digital Controller. If power is
turned ON for the Digital Controller before turning ON power for the load, self­tuning will not be performed properly and optimum control will not be
achieved. ST can be set for standard models only.

Operating Procedure This procedure executes self-tuning (ST).

Note PID Constants

When control characteristics are already known, PID constants can be set
directly to adjust control. PID constants are set in the Proportional Band (P),
Integral Time (I), and Derivative Time (D) parameters, according to the Dis­play PID Selection parameter setting in the PID setting level. Changing the
Proportional Band (P), Integral Time (I), or Derivative Time (D) parameter set­tings in the adjustment level changes the settings in these parameters in the
current PID set.

Startup Conditions Self-tuning by step response tuning (SRT) is started when the following condi-

tions are met after program execution is started and the set point is changed.

At start of operation When set point is changed

1. The set point at the start of operation
differs from the set point when the pre­vious SRT was executed. (See note 1.)

2. The difference between the tempera­ture at the start of operation and the set
point is greater both of the following:
(Present proportional band × 1.27 +
4°C) and the ST stable range.

3. The temperature at the start of opera­tion is lower than the set point during
reverse operation, and is larger than
the set point during direct operation.

4. There is no reset from input errors.

Note (1) The previous SRT-implemented set point is the set point that was used for

calculating the PID constants for the previous SRT.

(2) In this state, the measurement point is within the ST stable range.

(3) In this state, the change width of the PV every 60 seconds is within the

ST stable range or less.

In the following instances, PID constants are not changed by self-tuning (ST)
for the present set point.

1. When the PID constants have been changed manually with ST set to ON.

2. When auto-tuning (AT) has been executed.

3. When the PID set has been changed during SRT.

4. When the PID set for the current bank is set to 0 (PID set automatic selec­tion).

In addition, the following diagrams show the difference between setting a dif­ferent PID set for each bank and setting the same PID set. For details on bank
settings, refer to 4-15 Using Banks and PID Sets.

1. The new set point differs from the set
point used when the previous SRT was
executed. (See note 1.)

2. The set point change width is greater
both of the following: (Present propor­tional band × 1.27 + 4°C) and the ST
stable range.

3. During reverse operation, the new set
point is larger than the set point before
the change; and during direct opera­tion, the new set point is smaller than
the set point before the change.

4. The temperature is stable. (See note

2.) (Equilibrium with the output amount
at 0% when the power is turned ON is
also all right.) (See note 3.)

1,2,3... 1. When operation starts, ST is executed for each bank and the PID con-

stants are saved for each PID set. Stable control is thus enabled, because
ST is not executed when the bank is changed or when the next operation
starts.

2. ST is executed each time the bank is changed, and PID constants are
saved for the same PID set. Therefore ST is executed each time the bank
is changed and when the next operation starts.

3-8-3 RT (Robust Tuning)

• When AT or ST is executed with RT selected, PID constants are automat­ically set that make it hard for control performance to degenerate even
when the characteristics of the controlled object are changed.

• RT can be set in the advanced function setting level when PID control has
been set.

• The RT mode cannot be selected while an analog input is set.

• Selecting the RT mode in the following cases will help to prevent hunting
from occurring.

• When the set temperature is not constant and is changed in a wide

• When there are large variations in ambient temperatures due to factors

• When there are large variations in ambient wind conditions and air flow

• When heater characteristics change depending on the temperature

• When an actuator with disproportional I/O, such as a phase-control-

• When a rapidly heating heater is used

• When the control object or sensor has much loss time

Display PID Selection parameter set in the PID setting level. Changing the
Proportional Band (P), Integral Time (I), or Derivative Time (D) parameter set­tings in the adjustment level changes the settings in the current PID set. For
details on PID sets, refer to PID Sets on page 128.

Operating Procedure In this example, the PID 2 Proportional Band parameter is set to 10.0, the PID

2 Integral Time parameter to 250, and the PID 2 Derivative Time parameter to

45.

with new values. To retain the manually set PID constants, turn OFF the ST
parameter.

Related parameter: ST (Self-tuning) (initial setting level)

Note Proportional Action

When PID constants I (integral time) and D (derivative time) are set to 0, con­trol is executed according to proportional action. As the default, the center
value of the proportional band becomes the set point.

3-9-2 Alarm Values

• Alarm values are indicated by “X” in the table on the previous page. When
the upper and lower limits are set independently, “H” is displayed for
upper limit values, and “L” is displayed for lower limit values.

• To set the alarm upper and lower limits for deviation, set the upper and
lower limits in the Alarm 1 to 3 Upper Limit and Alarm 1 to 3 Lower Limit
parameters.

• Alarm values can be set for each bank. Select the bank number in the
Display Bank Selection parameter in the bank setting level, and set the
Alarm Value, Alarm Value Upper Limit (1 to 3), and Alarm Value Lower
Limit (1 to 3) parameters for that bank.

• When the Alarm Value, Alarm Value Upper Limit, and Alarm Value Lower
Limit parameters in the operation level are changed, the changes will be
reflected in those parameters for the current bank.

Operating Procedure This procedure sets alarm 1 for bank number 1 as an upper-limit alarm. The

related parameters and settings are shown below. The alarm is output when
the set point exceeds 10°C. (In this example, the temperature unit is °C.)

PV Change Rate Alarm The change width can be found for PV input values in any set period. Differ-

ences with previous values in each set period are calculated, and an alarm is
output if the result exceeds the alarm value. The PV rate of change calculation
period can be set in units of 60 ms.

If a positive value is set for the alarm value, the PV will operate as a change
rate alarm in the rising direction. If a negative value is set, the PV will operate
as a change rate alarm in the falling direction.

Precaution

If a shorter PV rate of change calculation period is set, outputs set for the PV
change rate alarm function may repeatedly turn ON and OFF for a short
period of time. It is therefore recommended that the PV change rate alarm be
used with the alarm latch turned ON.

3-10-1 Heater Burnout, Heater Short, and Heater Overcurrent Alarm

Operations

• Heater burnout detection and heater overcurrent detection are executed
by measuring heater current while the control output (heating) is ON, and
heater short detection is executed by measuring heater current while it is
OFF. For details, refer to the following table. (Heater burnout detection,
heater short detection, and heater overcurrent detection cannot be used
with the control output for cooling.)

Heater overcurrent

Note (1) In the above diagram, power is considered to be ON (normal) if the heater

current is greater than the heater burnout detection current during the Ton
interval. If the heater is burned out, the measured current decreases and
falls below the heater burnout detection value. The output is then activat­ed as the heater burnout alarm.

(2) In the above diagram, power is considered to be OFF (normal) if the leak-

age current is less than the HS alarm current during the Toff interval. If
the SSR output is short-circuited, the measured current increases be­yond the HS alarm value. The output is then activated as the HS alarm.

(3) In the above diagram, it is regarded as normal when the heater current is

less than the heater overcurrent detection current during the Ton period.
Current is increased when excessive current flows to the heater, causing
the heater overcurrent detection value to be exceeded and an OC (heater
overcurrent) alarm to be output.

(4) Heater burnout and heater overcurrent are not detected if the control out-

put (heating) ON time (Ton) is 100 ms or less.

(5) HS alarms are not detected if the control output (heating) OFF time (Toff)

is 100 ms or less.

• For Controllers with heater burnout, HS, and heater overcurrent alarms,
an OR output is established between the ALM 1 function and the alarms.
If the ALM1 function is to be used for the heater burnout, HS, and heater
overcurrent alarms only, set 0 as the alarm 1 type (i.e., do not use ALM1).

• Turn the heater power ON simultaneously or before turning ON the
E5N-H power. If the heater power is turned ON after turning ON the
E5AN-H power, the HB alarm will be activated.

• Control is continued even when the heater burnout, HS, or heater over­current alarm is active.

• The rated current value may sometimes differ slightly from the actual cur­rent flowing to the heater.
Use the Heater Current 1 Value Monitor, Heater Current 2 Value Monitor,
Leakage Current 1 Monitor, and Leakage Current 2 Monitor parameters to
check the actual current being used.

• If there is little difference between the current in normal and abnormal
states, detection may become unstable. To stabilize detection, set a cur­rent value difference of at least 1.0 A for heaters of less than 10.0 A, and
at least 2.5 A for heaters of 10.0 A or more. If the heater current is too low,
loop the load line several times through a CT, as shown in the diagram
below. Looping it through once will double the detection current.

3-10-2 Installing Current Transformers (CT)

• This function can be used with E5N-H models that have the HB alarm,
HS alarm, and OC alarm.
For the E5CN-H, connect the CT in advance to terminals 14 and 15
(CT1), or 13 and 15 (CT2). For the E5AN-H/EN-H, connect the CT in
advance to terminals 14 and 15 (CT1) or 15 and 16 (CT2). Then pass the
heater power line through the CT's hole.
For specifications, models and dimensions of current transformers that
can be used with this Controller, see Appendix Current Transformer (CT)
on page 298.

Single-phase Heaters For single-phase heaters, install the CT in the position shown in the following

diagram.

Three-phase Heaters
(E5N-HHH 3-phase
Heater Detection Models)

When a 3-phase power supply is used, regardless of the types of connecting

• Make sure that the following conditions are satisfied:
Heater with a current of less than 10.0 A:
(Current value at normal operation) − (Current value at heater burnout) ≥
1A
When the difference is less than 1 A, detection is unstable.
Heater with a current of 10.0 A or more:
(Current value at normal operation) − (Current value at heater burnout) ≥

2.5 A
When the difference is less than 2.5 A, detection is unstable.

• The setting range is 0.1 to 49.9 A. Heater burnout, HS, and heater over­current are not detected when the set value is 0.0 or 50.0. When the set
value is 0.0, the heater burnout alarm is always OFF, the HS alarm is
always ON, and the heater overcurrent alarm is always ON. When the set
value is 50.0, the heater burnout alarm is always ON, the HS alarm is
always OFF, and the heater overcurrent alarm is always OFF.

• Set the total current value for normal heater operation to 50 A or less.
When a current value of 55.0 A is exceeded, ffff is displayed in the
Heater Current 1 (or 2) Value Monitor and Leakage Current 1 (or 2) Moni­tor parameters.

3-10-4 Application Examples

Single-phase Heaters Example: Using a 200-VAC, 1-kW Heater

The heater power supply provides 5 A when the current is normal, and 0 A
when there is a burnout, so the heater burnout detection current is calculated
as follows:

Example: Using Three 200-VAC, 1-kW Heaters

Three-phase Heaters Delta Connecting Lines

Example: Using Three 200-VAC, 2-kW Heaters

The current when each phase is normal is 17.3 A (≈ √3 × 10 A).

The heater burnout current when there is a burnout at the load line is as fol­lows:

(Heater burnout detection current) = (17.3 + 15) / 2 ≈ 16.1 [A]

The heater burnout current when there is a burnout at the load is as follows:

(Heater burnout detection current) = (17.3 + 10) / 2 ≈ 13.65 [A]

To enable detection in either case, use 16.1 A as the heater burnout detection
current.
