■ Safety Precautions

Do not touch the terminals while power is being supplied. Doing so may occasionally result in minor injury due to electric shock.

Do not allow pieces of metal, wire clippings, or fine metallic shavings or filings from installation to enter the product. Doing so may occasionally result in electric shock, fire, or malfunction.

Do not use the product where subject to flammable or explosive gas. Otherwise, minor injury from explosion may occasionally occur.

Never disassemble, modify, or repair the product or touch any of the internal parts. Minor electric shock, fire, or malfunction may occasionally occur.

CAUTION - Risk of Fire and Electric Shock a) This product is UL listed as Open Type Process Control Equip-

ment. It must be mounted in an enclosure that does not allow fire to escape externally.

b) More than one disconnect switch may be required to de-

energize the equipment before servicing the product. c) Signal inputs are SELV, limited energy. d) Caution: To reduce the risk of fire or electric shock, do not inter-

connect the outputs of different Class 2 circuits.

CAUTION

If the output relays are used past their life expectancy, contact fusing or burning may occasionally occur. Always consider the application conditions and use the output relays within their rated load and electrical life expectancy. The life expectancy of output relays varies considerably with the output load and switching conditions.

*1 A SELV circuit is one separated from the power supply with double insulation or

reinforced insulation, that does not exceed 30 V r.m.s. and 42.4 V peak or 60 VDC.

*2 A class 2 power supply is one tested and certified by UL as having the current

and voltage of the secondary output restricted to specific levels.

CAUTION

Tighten the terminal screws to between 0.74 and 0.90 N·m. Loose screws may occasionally result in fire.

Set the parameters of the product so that they are suitable for the system being controlled. If they are not suitable, unexpected operation may occasionally result in property damage or accidents.

A malfunction in the Temperature Controller may occasionally make control operations impossible or prevent alarm outputs, resulting in property damage. To maintain safety in the event of malfunction of the Temperature Controller, take appropriate safety measures, such as installing a monitoring device on a separate line.

A semiconductor is used in the output section of long-life relays. If excessive noise or surge is impressed on the output terminals, a short-circuit failure is likely to occur. If the output remains shorted, fire will occur due to overheating of the heater or other cause. Take measures in the overall system to prevent excessive temperature increase and to prevent fire from spreading.

When inserting the body of the Temperature Controller into the case, confirm that the hooks on the top and bottom are securely engaged with the case. If the body of the Temperature Controller is not inserted properly, faulty contact in the terminal section or reduced water resistance may occasionally result in fire or malfunction.

*3 The tightening torque is 0.5 N·m for the E5CN-U and 0.43 to 0.58 N·m for the

E5GN. The terminal torque is 0.5 to 0.6 N·m for auxiliary output 2 on the E5GN.

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. Use the product within the specifications.

1) The product is designed for indoor use only. Do not use the product outdoors or in any of the following locations. Do not use or store the product 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 Temperature Controller within the rated ambient temperature and humidity. Gang-mounting two or more temperature controllers, or mounting temperature controllers above each

other may cause heat to build up inside the temperature 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 Temperature 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 the specified size of crimp terminals for the E5CN, E5AN, or E5EN (M3.5, width of 7.2 mm or less). For open-wired connections to the E5CN, E5AN, or E5EN, use stranded or solid copper wires with a

gauge of AWG24 to AWG14 (equal to a cross-sectional area of 0.205 to 2.081 mm length is 5 to 6 mm.) Up to two wires of the same size and type or two crimp terminals can be connected to one terminal. Do not connect more than two wires or more than two crimp terminals to the same terminal.

Use the specified size of crimp terminals for the E5GN (M3.0, width of 5.8 mm or less). For open-wired connections to the E5GN, use stranded or solid copper wires with a gauge of AWG24 to AWG18 (equal to

a cross-sectional area of 0.205 to 0.8231 mm The stripping length for screwless clamp terminals is 10 mm. The stripping length for auxiliary output 2 is 6 mm.) Up to two wires of the same size and type or two crimp terminals can be connected to one terminal. Do not connect more than two wires or more than two crimp terminals to the same terminal.

Ferrules for screwless clamp terminals must be 0.8 to 1.4 mm in diameter and the exposed conductor must be 8 to 12 mm in length. Ferrules for auxiliary output 2 must be 0.8 to 1.4 mm in diameter and the exposed conductor must be 6 mm in length.

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

7) To avoid inductive noise, keep the wiring for the Digital Temperature 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 Temperature 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 temperature controller. Allow as much space as possible between the Digital Temperature 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 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.

11) 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.

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 removing the body of the E5CN, E5AN, or E5EN from the case, 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. Always turn OFF the power supply before removing the terminal block from the E5GN, and never touch nor apply shock to the terminals or electronic components.

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

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 Temperature Controller to discharge static electricity from your body.

19) Do not remove the terminal block from the E5CN, E5AN, or E5EN. 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 E5CN, E5AN, or E5EN, check the condition of the terminals. If corroded terminals are used, contact failure in the terminals may cause the temperature inside the E5CN, E5AN, or E5EN to increase, possibly resulting in fire. If the terminals are corroded, replace the case as well. When removing the terminal block of the E5GN to replace the Digital Temperature Controller, check the condition of the terminals. If corroded terminals are used, contact failure in the terminals may cause the temperature inside the Digital Temperature Controller to increase, possibly resulting in fire. If the terminals are corroded, replace the terminal block as well.

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

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

24) Do not use the Temperature Controller if the front sheet is peeling off or torn.

● Service Life

Use the Temperature 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 Temperature 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 Temperature Controller.

xiii

When two or more Temperature 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 Temperature 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 Temperature 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 Temperature 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 Temperature 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 Temperature Controller. Allow as much space as possible between the Digital Temperature Controller and devices that generate powerful high frequencies (high-frequency welders, high-frequency sewing machines, etc.) or surge.

● 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 Temperature 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 (E5CN-U: Front panel: IP50, rear case: IP20, terminals: 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 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.)

■ Upgraded Functions

The functionality of the E5CN, E5CN-U, E5AN, and E5EN was improved starting from December 2007 production.

The functionality of the E5GN was improved starting from August 2009 production. The design of the front panel can be used to differentiate between the previous and upgraded models.

● E5CN/CN-U The upgraded Controllers are basically compatible with the previous Controllers. Terminal arrangements, terminal sizes, and panel mounting depth have not been changed.

● E5AN/EN Although the upgraded Controllers are compatible with the previous Controllers, terminal arrangements have been changed. Terminal sizes and panel mounting depth have not been changed.

● E5GN Model numbers have changed accompanying the introduction of universal input capability. The default setting of the input type parameter of the E5GN-@@@P (models with resistance thermometers) has been changed from a Pt100 resistance thermometer to a K thermocouple. Make sure the setting of the input type parameter agrees with the temperature sensor that is being used. The terminal block has also been changed, which means the wiring methods and terminal arrangement are different.

Other changes outlined in the following tables. Refer to relevant pages in the manual for details.

Conventions Used in This Manual

Model Notation

The E5CN-@@@, E5CN-@@@U, E5AN-@@@, E5EN-@@@, and E5GN-@@@ are given as the E5CN, E5CN-U, E5AN, E5EN, and E5GN when they share functionality. The following notation is used when specifying differences in functionality.

Notation Options

E5@N-@@@B Two event inputs E5@N-@@@03 RS-485 communications E5@N-@@H One of HB, HS, and heater overcurrent detection E5@N-@@HH Two of HB, HS, and heater overcurrent detection (See note 1.) E5@N-@Q Control output 2 (voltage output) (See note 1.) E5@N-@@P External power supply to ES1B (See note 1.) E5@N-@@@01 RS-232C communications (See note 2.) E5@N-@@F Transfer output (See note 3.)

Note: (1) Excluding the E5GN.

(2) Excluding the E5CN. (3) The E5AN and E5EN only.

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.

1-2-2 Main Functions

This section introduces the main E5CN/CN-U/AN/EN/GN functions. For details on particular functions and how to use them, refer to SECTION 3 Basic Operation and following sections.

Input Sensor Types • The following input sensors can be connected for temperature input

(i.e., E5_N-@@@@T): Thermocouple: K, J, T, E, L, U, N, R, S, B, W, PLII Infrared temperature sensor: ES1B

10 to 70°C, 60 to 120°C, 115 to 165°C, 140 to 260°C

Platinum resistance thermometer: Pt100, JPt100 Analog input: 0 to 50 mV

I/O Configuration and Main Functions Section 1-2

• Inputs with the following specifications can be connected for analog input

(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.)

Long-life relay output

Varistor

Inductive load

Select a surge absorber that satisfies the following conditions.

Voltage used Varistor voltage Surge resistance

100 to 120 VAC 240 to 270 V 1,000 A min. 200 to 240 VAC 440 to 470 V

• 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.

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.

Heater Burnout, HS Alarm, and Heater Overcurrent

• With the E53-CN@H@N2 or E53-CN@HH@N2 for the E5CN, or the E5AN/EN-@@H@-500-N or E5AN/EN-@@HH@-500-N, the heater burnout detection function, HS alarm function, and heater overcurrent detection function can be used.

Transfer Output A transfer output for 4 to 20 mA can be used with the E5AN/E5EN-@@F.

For E5@N-C@@ models (models without “F” in the model number), the current output can be used as a simple transfer output.

Setting Level Configuration and Key Operations Section 1-3

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.

these four levels is selected. (4) When the PF Setting is set to A-M in models with a PF Key (E5AN/EN) (5) When the PF Setting is set to PFDP in models with a PF Key (E5AN/EN)

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

Calibration Level • To move to the calibration level, input the password (1201) from the

• 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.

advanced function setting level. The calibration level is for offsetting error in the input circuit.

• You cannot move to other levels from the calibration level by operating the keys on the front panel. To cancel this level, turn the power OFF then back ON again.

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.) For details, refer to SECTION 5 Parameters.

Communications Function Section 1-4

1-3-2 Saving Settings

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.

Since the voltage output (control output) is not electrically insulated from the internal wiring, one or other of the control output terminals must be left unearthed when using an earthed thermocouple thermometer. (Connection makes measurements unreliable due to sneak currents.)

To comply with EMC standards, the length of the cable connecting the analog input or universal TC/Pt input sensor must be 30 m or less. If the cable is longer than 30 m, the EMC standards will not be satisfied.

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

• The 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.

• Control output 1 (voltage output for driving SSR) and control output 2 (voltage output for driving SSR) are not isolated. For the E5AN/EN, however, the internal circuits are functionally isolated.

• Long-life relay outputs 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.)

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

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.

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.

Manipulated variable Manipulated variable

100%

Low temperature

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.

Input type = s (K thermocouple) Temperature unit = c (°C) Direct/reverse operation = or-r (reverse operation) Control period (heat) = 20 (seconds)

Note (1) There is no control output 2 and no parameter assignment is displayed

for that output.

(2) The Auxiliary Output 1 Assignment parameter becomes the program end

output unless the Program Pattern parameter is set to OFF.

(3) For the E5AN/EN, the Auxiliary Output 3 Assignment parameter is set as

the control output for cooling. (The Auxiliary Output 2 Assignment parameter is set for alarm 2).

■ 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

Using ON/OFF Control Section 3-7

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.

5. To return to the operation level, press the O Key.

• 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.
