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

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

b) When using more than one shutoff switch, always turn OFF all

the shutoff switches to ensure that no power is being supplied

before servicing the product. c) Signal inputs are SELV, limited energy. (See note 1.) d) Caution: To reduce the risk of fire or electric shock, do not

interconnect the outputs of different Class 2 circuits. (See note

2.)

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.

Note 1: An 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.

Note 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 Digital 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 Digital Controller, take appropriate safety measures, such as installing a monitoring device on a separate line.

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

When connecting the Control Output Unit to the socket, press it in until there is no gap between the Control Output Unit and the socket. Otherwise contact faults in the connector pins may occasionally result in fire or malfunction.

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

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.

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.

● 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

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 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-H as possible. (As a guideline, the ferrite core should be within 10 cm of the terminal block.)

1-2-2 Main Functions

This section introduces the main E5@N-H 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.:

Thermocouple: K, J, T, E, L, U, N, R, S, B, W, PLII Platinum resistance thermometer: Pt100, JPt100 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

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 (cool-

ing) 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.

Heater Burnout, HS Alarm, and Heater Overcurrent

Communications Functions

Note (1) CompoWay/F is an integrated general-purpose serial communications

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

• Communications functions utilizing CompoWay/F (See note 1.), SYSWAY (See note 2.), or Modbus (See note 3.) can be used.

RS-485 Interface Use the E53-CN@03N2 for the E5CN-H, or the E53-EN03 for the E5AN/ EN-H.

RS-232C Interface Use the E53-CN@01N2 for the E5CN-H, or the E53-EN01 for the E5AN/ EN-H.

RS-422 Interface Use the E53-EN02 for the E5AN/EN-H.

protocol developed by OMRON. It uses commands compliant with the well-established FINS, together with a consistent frame format on OMRON Programmable Controllers to facilitate communications be-

tween personal computers and components. (2) SYSWAY communications do not support alarm 3. (3) Modbus is a communications control method conforming to the RTU

Mode of Modbus Protocol. Modbus is a registered trademark of

Schneider Electric.

I/O Configuration and Main Functions Section 1-2

(4) The E5CN-H does not support the RS-422 interface.

Transfer Output A 4 to 20-mA transfer output can be used with the E53-CN@FN2 for the

E5CN-H, or the E5AN/EN-H@@F-500.

Remote SP Inputs Remote SP inputs can be used with the E5AN-H and E5EN-H.

Infrared Communications When Support Software, such as CX-Thermo version 4.00 or later (EST2-2C-

MV4 or later), is used, the personal computer can be connected to the Digital Controller using infrared communications.

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.

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.

• To move to the advanced function setting level, set the Initial Setting/Communications Protect parameter in the protect level to 0 (the default) 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.

1-4 Communications Function

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.

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 onoff, ON/OFF control, is selected. The default is pid. ON/OFF control is not displayed for position-proportional models.

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).

Setting Output Specifications Section 3-5

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.

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 pid.

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

Using ON/OFF Control Section 3-7

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.

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

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 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 129.

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

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.

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.

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

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 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 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.)

• These settings can be made for standard models only.

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.

alarm output

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

• 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.

Load line

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 300.

3-10-3 Calculating Detection Current Values

• Calculate the set value using the following equation:

Heater Burnout Detection 1/2 set value =

Normal current value + Burnout current value

HS Alarm 1/2 set value =

Heater overcurrent 1/2 set value =

• 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.

Leakage current value (output OFF) + HS current value

Normal current value + Overcurrent value

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.

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

Heater burnout detection current = (10 + 5) / 2 ≈ 7.5 [A]

The heater burnout current when there is a burnout at the load is as follows: Heater burnout detection current = (10 + 0) / 2 ≈ 5 [A]

To enable detection in either case, use 7.5 A as the heater burnout detection current.
