No patent liability is assumed with respect to the use of the information contained herein. Moreover, because OMRON is constantly striving to improve its high-quality products, the information contained in this manual is subject to change without notice. Every precaution has been taken in the preparation of this manual. Nevertheless, OMRON assumes no responsibility for errors or omissions. Neither is any liability assumed for damages resulting from the use of the information contained in this publication.

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 Temperature Controllers into a control panel or similar device.

2) Make sure that the Temperature 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 Temperature Controller. If power is turned ON for the Temperature 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 Temperature 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 Temperature 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 E5CN, E5CN-H, E5AN, E5AN-H, E5EN, and E5EN-H 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 E5CN, E5CN-H, E5AN, E5AN-H, E5EN, and E5EN-H comply with installation category ENV1 and ENV2 of Lloyd's standards. Therefore, they must be installed in a location equipped with air conditioning. They must therefore be installed in a location equipped with air conditioning. They cannot be used on the bridge or decks, or in a location subject to strong vibration.

2) Wiring Conditions

Install the recommended ferrite core and wrap the line around it three turns for the applicable lines (e.g., power supply cable line and signal lines) of the models listed in the following table. (See illustrations.) Install the ferrite cores as close to the terminal block of the E5@N as possible. (As a guideline, the ferrite core should be within 10 cm of the terminal block.)

Meanings of Abbreviations

The following abbreviations are used in parameter names, figures and in text explanations. These abbreviations mean the following:

Symbol Term

PV Process value

SP Set point

SV Set value

AT A ut o - tu n i ng

ST Self-tuning

HB Heater burnout

HS Heater short (See note 1.)

OC Heater overcurrent

LBA Loop burnout alarm

EU Engineering unit (See note 2.)

Note: (1) A heater short indicates that the heater remains ON even when the control output from the Tempera-

ture Controller is OFF because the SSR has failed or for any other reason.

(2) “EU” stands for Engineering Unit. EU is used as the minimum unit for engineering units such as °C,

m, and g. The size of EU varies according to the input type. For example, when the input temperature setting range is –200 to +1300°C, 1 EU is 1°C, and when the input temperature setting range is –20.0 to +500.0°C, 1 EU is 0.1°C. For analog inputs, the size of EU varies according to the decimal point position of the scaling setting, and 1 EU becomes the minimum scaling unit.

(i.e., E5_N-@@@@L): Current input: 4 to 20 mA DC, 0 to 20 mA DC Voltage input: 1 to 5 VDC, 0 to 5 V DC, 0 to 10 V DC

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

put, depending on the model.

• Long-life relay outputs (see note) use semiconductors for switching when closing and opening the circuit, thereby reducing chattering and arcing and improving durability. However, if high levels of noise or surge are imposed between the output terminals, 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. Take countermeasures such as installing a surge absorber. As an additional safety measure, provide error detection in the control loop. (Use the Loop Burnout Alarm (LBA) and HS alarm that are provided for the E5@N.)

• Always connect an AC load to a long-life relay output (see note). The output will not turn OFF if a DC load is connected.

Note Long-life relay outputs are not supported for the E5GN.

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.

I/O Configuration and Main Functions Section 1-2

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 or the E5AN/EN-@M@-500-N with

the E53-AKB for the E5AN/EN, the following functions can be executed using event inputs: switching set points (multi-SP, 4 points max.), switching RUN/STOP, switching between automatic and manual operation, starting/resetting the program, inverting direct/reverse operation, 100% AT execute/cancel, 40% AT execute/cancel, setting change 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/CN-U/AN/EN/GN are divided into the following 9 levels.

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

Note (1) You 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, or the monitor/setting item 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, multi-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 top parameter of the initial setting level, protect level, or operation level.

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

operation level or adjustment 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. (This level is supported by the E5AN and E5EN 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 or adjustment level, the manual control level will be displayed (E5AN and E5EN 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.

Setting Level Configuration and Key Operations Section 1-3

Initial Setting Level • To move to the initial setting level from the operation level or the adjust-

ment 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.

Advanced Function Setting Level

Communications Setting Level

• To move to the advanced function setting level, set the Initial Setting/Communications Protect parameter in the protect level to 0 and then, in the initial setting level, input the password (−169).

• 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 read and written, and manipulated variables (MV) to be monitored.

1-3-1 Selecting Parameters

• Within each level, the parameter is changed in order (or in reverse order) each time the M Key is pressed. (In the calibration level, however, parameters cannot be changed in reverse order.)

Communications Function Section 1-4

1-3-2 Saving Settings

Moves in order after M key is pressed (if key is released within 1 s).

Parameter 1

While the M key is being held down, the parameter will move each second in reverse order.

Parameter 2

Parameter 3

Hold down the M key

After M key is pressed

Parameter 4

• 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.

3. To return to the operation level, press the O Key for at least one second.

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 onof, ON/OFF control, is selected. The default is onof.

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).

3-5 Setting Output Specifications

3-5-1 Control Periods

• 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 control output 1 is used as a current output, Control Period (Heating) cannot be used.

3-5-2 Direct and Reverse Operation

• Direct operation increases the manipulated variable whenever the process value increases. Reverse operation decreases the manipulated variable whenever the process value increases.

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. The Control Output 1 Assignment is set to o (control output (heating)) for either direct or reverse operation.

• 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 to 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

Operation Level

The operation level is displayed when the power is turned ON. The process value (PV) is at the top of the display, and the set point (SP) is at the bottom.

For Controllers that support a No. 3 display (E5AN/E5EN), the contents set in the PV/SP Display Screen Selection parameter (advanced function setting level) are displayed below the PV and SP.

The MV is displayed as the default. For details, refer to 3-11 Setting the No. 3 Display.

3-6-1 Changing the SP

• The set point cannot be changed when the Operation/Adjustment Protect

parameter is set to 3. For details, refer to 4-9 of H156 Using the Key Pro- tect Level.

• To change the set point, press the U or D Key in the Process Value/Set Point parameter (in the operation level), and set the desired set value. The new set point is selected two seconds after you have specified the new value.

• Multi-SP is used to switch between two or four set points. For details, refer

to 4-5 of H156 Using Event Inputs for details.

Operating Procedure In this example, the set point is changed from 0°C to 200°C.

Operation Level

1. Normally, the Process Value/Set Point parameter is displayed. The set point is 0°C.

2. Use the U and D Keys to set the set point to 200°C.

Using ON/OFF Control Section 3-7

Hysteresis (heating)

Set point

3-7 Using 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.

3-7-1 ON/OFF Control

• 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 onof.

Hysteresis • With ON/OFF control, hysteresis is used to stabilize operation when

switching between ON and OFF. The control output (heating) and control output (cooling) functions are set in the Hysteresis (Heating) and Hysteresis (Cooling) parameters, respectively.

• In standard control (heating or cooling control), the setting of the Hysteresis (Heating) parameter in the adjustment level is used as the hysteresis regardless of whether the control type is heating control or cooling control.

Three-position Control

• In heating/cooling control, a dead band (an area where both control outputs are 0) can be set to either the heating or cooling side. This makes it possible to use 3-position control.

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 can- cel).

• Only 100% AT can be executed for heating and cooling control.

• 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 in the adjustment level.

3-8-2 ST (Self-tuning)

ST (self-tuning) is a function that finds PID constants by using step response

tuning (SRT) when 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 Temperature Controller. If power is turned ON for the Digital Temperature Controller before turning ON power for the load, self-tuning will not be performed properly and optimum control will not be achieved.

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 in the adjustment level.

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

The temperature display flashes during self-tuning (ST) execution.

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.

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.)

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.

1,2,3... 1. When the PID constants have been changed manually with ST set to ON.

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

3-8-3 RT (Robust Tuning)

• When AT or ST is executed with RT selected, PID constants are automat-

ically 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 range

• When there are large variations in ambient temperatures due to factors such as seasonal changes or differences between day and night temperatures

• 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-controltype power regulator, is used

• When a rapidly heating heater is used

• When the control object or sensor has much loss time

• When hunting occurs in normal mode for any reason

• PID constants are initialized to the factory settings by switching to RT mode.

• When the RT mode is selected, the derivative time setting unit becomes the second.

RT Features • Even when hunting occurs for PID constants when AT or ST is executed

in normal mode, it is less likely to occur when AT or ST is executed in RT mode.

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 250 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.

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.

Load Load (such as a heater)

AC line

Product To CT input

• 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 power. If the heater power is turned ON after turning ON the E5AN 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.

Load line

3-10-2 Installing Current Transformers (CT)

• This function can be used with E5@N models that have the HB alarm, HS alarm, and OC alarm. For the E5CN, connect the CT in advance to terminals 14 and 15 (CT1), or 13 and 15 (CT2). For the E5AN/E5EN, connect the CT in advance to terminals 14 and 15 (CT1) or 15 and 16 (CT2). For the E5GN, connect the CT in advance to terminals 7 and 8 (CT1). 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, refer to Appendix Current Transformer (CT) on page 279 of H156 .

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

diagram.

Three-phase Heaters (E5AN-@@HH@-N, E5EN-@@HH@-N, and E53-CN@@HHN2 (for E5CN) 3-phase Heater Detection Models)

When a 3-phase power supply is used, regardless of the types of connecting lines, two current transformers (CTs) are required to detect heater burnout, HS, and OC.

3-10-3 Calculating Detection Current Values

• Calculate the set value using the following equation:

• To set the current for heater burnout when two or more heaters are connected through the CT, use the value from when the heater with the smallest current burns out. If all of the heaters have the same current, use the value from when any one of them burns out.

Using Heater Burnout, Heater Short, and Heater Overcurrent Alarms Section 3-10

• 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.

4-1-1 Shifting Inputs

The input shift matched to the sensor currently selected in the Input Type parameter is displayed.

• A 2-point shift is applied for infrared temperature sensors. A 2-point shift can also be used if the Input Shift Type parameter (advanced function setting level) is set to INS2 for a thermocouple or platinum resistance thermometer.

• There is no shift for analog inputs. Use scaling for fine adjustments.

One-point shift

• With a 1-point shift, the value set for the Temperature Input Shift parameter (adjustment level) is applied to each point in the entire temperature input range. For example, if the input shift value is set to 1.2°C, the process value is treated as 201.2°C after the input shift is applied when the measured process value is 200°C.

Shifting Input Values Section 4-1

Two-point shift

• Separate shift values can be set for the upper limit and lower limit of the sensor input range for an infrared sensor as well as for a thermocouple or platinum resistance thermometer with the Input Shift Type parameter set to INS2. If different shift values are set for the upper limit and lower limit, then the slope of the line will be different before and after applying the input shift. For example, if the upper-limit value is set to 2°C and the lower-limit value is set to 1°C, the input temperature will be shifted by

1.5°C for a 50% input, i.e., by the average of the upper-limit and lowerlimit values.

• Set the upper-limit value in the Upper-limit Temperature Input Shift Value parameter and the lower-limit value in the Lower-limit Temperature Input Shift Value parameter.

4-1-2 How to Calculate Input Shift Values for a 2-point Shift

When an ES1B Infrared Temperature Sensor is connected to the E5CN, an offset of several degrees to several tens of a degree can occur.

For this reason, offset the readout value using a 1-point or 2-point shift as described in this section. This offset occurs because a bias current for detecting a Controller sensor error flows to the output impedance of the infrared temperature sensor.

Preparations

1,2,3... 1. Set a temperature range matching the input specifications of the infrared

temperature sensor. (The ES1B can be used with the E5@N only for a thermocouple/resistance thermometer universal input.)

2. Prepare a thermometer capable of measuring the temperature of the con-

trol target as shown in Figure 1 so that a 1-point shift or 2-point shift can

be carried out.

3. The E53-CN@@P@N2 (for E5CN), E5AN-@@P@-N, or E5EN-@@P@-N

has a built-in external power supply for ES1B Infrared Temperature Sensors. These E5CN models can be used as the power supply when using ES1B. When ES1B are used with other E5CN models, provide a separate power supply for the Infrared Temperature Sensors.

2. Check the thermometer temperature (B) and the Controller readout (A). Subtract the Controller readout temperature (A) from the thermometer temperature (B), and set insl and insh to the result as the input shift val-

ue. The shift is illustrated in Figure 2.

3. After setting the input shift values, check the Controller readout (A) and the thermometer temperature (B). If they are almost the same, this completes shifting the temperature input.

• Y1 is the Controller readout at room temperature before shifting and X1 is the Controller readout at room temperature after shifting.

• Y2 is the Controller readout at the set temperature before shifting and X2 is the Controller readout at the set temperature after shifting.

• Set the upper-limit temperature input shift and the lower-limit temperature input shift using the following formulas based on the temperatures before shifting (Y1 and Y2), the temperatures after shifting (X1 and X2), the set temperature upper limit (YH), and the set temperature

lower limit (YL). The shift is illustrated in Figure 3.

OFF

Alarm value

4-2-1 Standby Sequence

• The standby sequence can be used so that an alarm will not be output until the process value leaves the alarm range once and then enters it again.

• For example, with a lower limit alarm, the process value will normally be below the set point, i.e., within the alarm range, when the power supply is turned ON, causing an alarm to be output. If the lower limit alarm with a standby sequence is selected, an alarm will not be output until the process value increases above the alarm set value, i.e., until it leaves the alarm range, and then falls back below the alarm set value.

Restart • The standby sequence is canceled when an alarm is output. It is, how-

ever, restarted later by the Standby Sequence Reset parameter (advanced function setting level). For details, refer to the Standby

Sequence Reset parameter in SECTION 5 of H156 Parameters.

4-2-2 Alarm Latch

• The alarm latch can be used to keep the alarm output ON until the latch is canceled regardless of the temperature once the alarm output has turned ON.

Any of the following methods can be used to clear the alarm latch.

• Turn OFF the power supply. (The alarm latch is also cleared by switching to the initial setting level, communications setting level, advanced function setting level, or calibration level.)

•Use the PF Key.

• Use an event input.

• The heating/cooling operation of the control outputs will switch when the Direct/Reverse Operation parameter is set to “direct.”

• When DRS (Invert Direct/Reverse Operation) is assigned for an Event Input Assignment (1 or 2), control will start with the contents set for the Direct/Reverse Operation parameter inverted when the event input turns ON, and with the contents left according to the setting when the event input turns OFF. For details on event inputs and control combined with the

Direct/Reverse Operation parameter, refer to Control by Inver ting Direct/ Reverse Operation on page 78.

• When heating/cooling control is selected, the Dead Band and Cooling Coefficient parameters can be used.

Dead Band • For heating/cooling control, 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 (adjustment level). Setting a negative value produces an overlapping band.

• If an overlapping band is set, the bumpless function may not operate when switching between manual operation and automatic operation.

• The default is 0.0 EU for Controllers with Thermocouple/Resistance Thermometer Universal Inputs and 0.00% FS for Controllers with Analog Inputs.

Cooling Coefficient If the heating characteristics and cooling characteristics of the control object

are very different and good control characteristics cannot be achieved with the same PID constants, the cooling coefficient can be used to adjust the proportional band (P) for the control output assigned to the cooling side. Use this to achieve balanced control between the heating side and cooling side. The proportional bands (P) for the control outputs assigned to the heating/cooling sides can be calculated using the following equations.

P for control output assigned to heating side = P

P for control output assigned to cooling side = P for control output assigned to heating side × cooling coefficient

The cooling coefficient is multiplied by the P for the control output assigned to the heating side to obtain control with characteristics that differ from those of the control output assigned to the heating side.

Automatic Cooling Coefficient Adjustment

By executing AT during heating/cooling control, the cooling coefficient can be automatically calculated along with the PID parameters.

• Event inputs can be used for Multi-SP, RUN/STOP, Auto/Manual Switch, Program Start, Invert Direct/Reverse Operation, 100% AT Execute/Cancel, 40% AT Execute/Cancel, Setting Change Enable/Disable, and Alarm Latch Cancel.

• Of these, only the number of event inputs (0 to 2) set in the Number of Multi-SP Uses parameter (initial setting level) are used for the multi-SP function.

• Of these, only the number of event inputs (0 to 2) set in the Number of Multi-SP Uses parameter (initial setting level) are automatically assigned by the multi-SP function. Displays for event input assignments will not be displayed for inputs that are automatically assigned by the multi-SP function. Event inputs 1 and 2 are used for the multi-SP function by models with four event inputs.

• Event inputs can be used on the following models: E5CN-@M@-500 with the E53-CN@B@N2 for the E5CN E5AN/EN-@M@-500-N with the E53-AKB for the E5AN/EN

• When using event inputs to switch the multi-SP, the event input assignment display will not appear. Whether the set value and event input assignments 1 and 2 will be displayed or hidden is shown in the tables below.

• Do not connect the contacts from the same switch to more than one E5@N Controllers.

4-6 Setting the SP Upper and Lower Limit Values

4-6-1 Set Point Limiter

The setting range of the set point is limited by the set point limiter. This function can be used to prevent setting incorrect process values. The set point limiter is used to prevent the control target from reaching abnormal temperatures. If the set point is not within the range set for the set point limiter as the result of changes to the Set Point Upper Limit or Set Point Lower Limit parameter, the set point will automatically be change to a value within the set

range. The upper- and lower-limit values of the set point limiter are set using the Set Point Upper Limit and Set Point Lower Limit parameters in the initial setting level. 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 input type and the temperature unit, scaling upper-limit value, or lower-limit value are changed, the set point limiter is forcibly reset to the input setting range or the scaling upper- or lower-limit value.

2. Use the U and D Keys to set the parameter to −100.

4-7 Using the SP Ramp Function to Limit the SP Change Rate

4-7-1 SP Ramp

The SP ramp function is used to restrict the width of changes in the set point as a rate of change. When the SP ramp function is enabled and the change width exceeds the specified rate of change, an area where the set point is restricted will be created, as shown in the following diagram.

During the SP ramp, control will be performed not for the specified set point but rather for the set point restricted by the rate of change set for the SP ramp function.

SP after change

SP before change

Point of chan

The rate of change during SP ramp is specified using the SP Ramp Set Value and SP Ramp Time Unit parameters. The SP Ramp Set Value parameter is set to OFF by default, i.e., the SP ramp function is disabled.

Changes in the ramp set point can be monitored in the Set Point During SP Ramp parameter (operation level). Use this parameter when monitoring SP ramp operation.

The SP ramp function operates in the same way when switching the set point using the multi-SP function.

Operation at Startup If the SP ramp function is enabled when the Controller is turned ON or when

switching from STOP to RUN mode, the process value reaches the set point using the SP ramp function in the same way as when the set point is changed. In this case, operation is carried out with the process value treated as the set point before the change was made. The direction of the SP ramp changes according to the relationship between the process value and the set point.
