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. Do not handle the Controller in ways that exceed product specifications.

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

• 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

). (The stripping length is 5 to 6 mm.) Up to two wires of same size and type, or two crimp

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) 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.

12) 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.

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

14) Design system considering the 2 second of delay that the controller’s output to be set after power ON.

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

Precautions for Safe Use

xiii

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

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

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

19) 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.)

20) 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.

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

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

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

24) Do not continue to use the Controller if the front surface peels or becomes cracked.

● 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.

Page 14

xiv

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

To install the Controller so that it is waterproof, insert the Waterproof Packing. The degree of protection when the Waterproof Packing is used is IP66. To maintain an IP66 degree of protection, the Waterproof Packing should be periodically replaced because it may deteriorate, shrink, or harden depending on the operating environment. The replacement period will vary with the operating environment. Check the required period in the actual application. Use one year as a guideline. If the Waterproof Packing is not periodically replaced, waterproof performance may not be maintained. If a waterproof structure is not required, then the Waterproof Packing does not need to be installed.

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

Be sure to thoroughly read and understand the manual provided with the product, and check the following points.

1-1-3 Using the Keys

This section describes the basic functions of the front panel keys.

PF (Function or Run/ Reset) Key (E5AN-HT and E5EN-HT Only)

This is a programmable function key. When it is pressed for at least 1 second, the function set in the PF Setting parameter will operate.

Example for When the PF Setting Parameter Is Set to R-R (Default: R-R): With this setting, the PF Key operates as a Reverse Run/reset Key to switch

between run status and reset status. The status changes from reset to run status when the key is pressed for at

least one second and changes from run to reset status when the key is pressed for at least two seconds.

O Key Press this key to move between setting levels. The level is selected in the fol-

lowing order: operation level, program setting level, adjustment level, PID setting level, and then operation level. From initial setting level you can go to and from communications setting level.

M Key Press this key to change parameters within a setting level.

The parameters can be reversed by holding down the key (moving one per second in reverse order).

U Key Each press of this key increments the value displayed on the No. 2 display or

advances the setting. Holding the key down speeds up the incrementation.

D Key Each press of this key decrements values displayed on the No. 2 display or

reverses the setting. Holding the key down speeds up the incrementation.

O + M Keys Press these keys to change to the protect level. For details on operations

involving holding these keys down simultaneously, refer to 1-3 Setting Level

Configuration and Key Operations. For details on the protect level, refer to SECTION 5 Parameters.

O + U Keys O + D Keys

To restrict set value changes (in order to prevent accidental or incorrect operations), these key operations require simultaneously pressing the O key along with U or D key. This applies only to the parameter for the password to move to protect level. (Refer to page 182.)

M + U Keys (E5CN-HT Only)

The function that is set for the PF Setting parameter will operate when the Mode Key and Up Key are pressed at the same time for at least one second. They perform the same function as the PF Key. If you are using the E5CN-HT, use the M+U Keys whenever the manual says to use the PF Key.

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, or current output, depending on the model.

• With the E5CN-HT@2@@, auxiliary output 2 is used as control output

(cooling) when heating/cooling control is selected. (It is also possible to allocate a different output.) Therefore, use auxiliary output 1 if an auxiliary output is required while using heating/cooling control.

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

limits.

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

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

• If the Remote SP Input Error Output parameter is set to ON, the output assigned to the alarm 1 function will turn ON when a remote SP input error occurs. The remote SP function is supported only by the E5AN-HT and E5EN-HT.

Control Adjustment • Auto-tuning can be executed to easily set the optimum PID constants. Event Inputs • With the E5@N-HT@@@B, the following functions can be executed using

event inputs. Any of the following can be specified: switching programs, run/reset, reset, run, switching automatic/manual operation, hold/clear hold, hold, advance, Program SP Mode/Remote SP Mode (E5AN-HT or E5EN-HT only), Remote SP Mode/Fixed SP Mode (E5AN-HT or E5ENHT only), Program SP Mode/Fixed SP Mode, wait enable/disable, invert direct/reverse operation, 100% AT execute/cancel, 40% AT execution/cancel, setting change enable/disable, communications writing enable/disable, and alarm latch cancel.

Heater Burnout, HS Alarm, and Heater Overcurrent

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

Communications Functions

• Communications functions utilizing CompoWay/F (See note 1.) or Modbus (See note 2.) 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-HT, or the E53-EN01 for the E5AN/ EN-HT.

RS-422 Interface (See note 3.) Use the E53-EN02 for the E5AN/EN-HT.

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

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 between personal computers and components.

(2) Modbus is a communications control method conforming to the RTU

Mode of Modbus Protocol. Modbus is a registered trademark of Schneider Electric.

(3) The E5CN-HT does not support the RS-422 interface.

Page 33

I/O Configuration and Main Functions Section 1-2

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-HT@@F-500.

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

Infrared Communications When Support Software, such as CX-Thermo version 4.30 or later (EST2-2C-

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

the M+U Keys at the same time to implement the PF Key.

Protect Level • To switch to the protect level, simultaneously hold down the O and M

Keys for at least 3 seconds from the operation level, the program setting level, adjustment level, or PID setting level. (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 program setting level from this level.

• Operation level should be used during normal operation. The PV, MV, or other values can be monitored during operation. Hold and advance commands can also be used.

Program Setting Level • To move to the program setting level, press the O Key once from the

operation level for less than 1 s.

• In this level, the SPs, times, rates of rise, and other parameters are input for the programs. From the program setting level, you can move to the adjustment level, initial setting level, or protect level.

Adjustment Level • To move to the adjustment level, press the O Key once from the program

setting level 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, you can move to the PID setting level, initial setting level, or protect level.

PID Setting Level • To move to the PID setting level, press the O Key once from the adjust-

ment level 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.

Calibration level --- Can be set. Communications setting level --- Can be set.

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, program setting level, adjustment 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.)

• If the PF Setting parameter is set to A-M (auto/manual), the manual control level can be displayed by pressing the PF Key for more than one second from the operation level, adjustment level, program setting level, or PID setting level.

• 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 switch to the protect level, simultaneously hold down the O and M

Keys for at least 3 seconds from the operation level, program setting level, adjustment level, or PID setting level. 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

• 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.

Communications Setting Level

• 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.

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

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.

Page 37

Communications Function Section 1-4

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.

1-3-2 Saving Settings

• 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.

1-4 Communications Function

The E5CN-HT, E5AN-HT, and E5EN-HT Digital Controllers are provided with communications to enable parameters to be checked and set from a host computer. If communications is required, use a model that supports communications (E5@N-HT@@@03, E5@N-HT@@@01, or E5AN/EN-HT@@@02). For details on communications, refer to the E5CN-HT/E5AN-HT/E5EN-HT Digital Controller Communications Manual Programmable Type (Cat. No. H170). Use the following procedure to move to the communications setting level.

1,2,3... 1. Press the O Key for at least three seconds to move from the operation lev-

el to the initial setting level.

2. Press the O Key for less than one second to move from the initial setting

2-2-2 Precautions when Wiring

• Separate input leads and power lines in order to prevent external noise.

• Use AWG24 (cross-sectional area: 0.205 mm

) to AWG14 (cross-sec-

tional area: 2.081 mm

) twisted-pair cable (stripping length: 5 to 6 mm).

• Use crimp terminals when wiring the terminals.

• Use the suitable wiring material and crimp tools for crimp terminals.

• Tighten the terminal screws to a torque of 0.74 to 0.90 N·m.

• Use the following types of crimp terminals for M3.5 screws.

Note Do not remove the terminal block. Doing so will result in malfunction or failure.

2-2-3 Wiring

In the connection diagrams, the left side of the terminal numbers represents the inside of the Controller and the right side represents the outside.

Power supply • With the E5CN-HT, connect to terminals 9 and 10; with the E5AN-HT and

E5EN-HT, connect pins 1 and 2. The following table shows the specifications.

• These models have reinforced insulation between the input power supply, the relay outputs, and other terminals.

Input • Make the connections as shown below, using terminals 3 to 5 for the

E5CN-HT and pins 17 to 20 for the E5AN/EN-HT, and matching the input types.

Note When wiring a voltage input, check the connected terminals care-

fully to make sure there are no mistakes. The Digital Controller may fail if the voltage input terminals are wired incorrectly.

■ Output Units

• The E5CN-HT 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.

• Either °C or °F can be selected as the temperature unit.

• Set the temperature unit in the Temperature Unit parameter of the initial setting level. The default is c (°C).

Operating Procedure The following example shows how to select °C as the temperature unit.

3-4 Selecting PID Control or ON/OFF Control

3-4-1 PID·ON/OFF (cntl)

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.

2-PID Control Use auto-tuning to set the PID constants, or set them manually.

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

The following table shows the parameters related to outputs. Each of the parameters is described in detail following the table.

(

●: Supported)

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

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

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.

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. For either direct or reverse operation, assign control output 1 to o (control output (heating)).

• 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)

3-5-3 Assigned Output Functions

• Function assignments can be changed by changing the settings for control and auxiliary output assignments.

■ 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 alarms and time signals. For example, if work bit 1 is set for the Auxiliary Output 1 Assignment parameter, then alarms 1 to 3 and time signals 1 and 2 are assigned.

Setting Programs Section 3-6

3-6 Setting Programs

3-6-1 Outline of Program Functions

• Up to 8 programs (patterns) can be created and each program can have up to 32 segments (steps).

• Programming is possible either by setting the SP and time for each segment (step time programming) or by setting the target SP, rate of rise, and time for each segment (rate of rise programming).

• Program repetitions and a program link destination can be set for each program.

• You can hold measurements during operation, or advance operation to skip segments.

• If you set a wait band, each segment will wait until the PV reaches a specified band before operation moves to the next segment.

• Outputs can be assigned to time signal outputs, program end outputs, run outputs, or stage outputs.

3-6-2 Program Settings

Here, the procedure is given for using step time programming. For the procedure for rate of rise programming, refer to 4-15 Program-related Functions.

Selecting the Program Number (d.prg)

• The Display Program Selection parameter specifies the number of the program to be set.

• The default is the number of the currently selected program.

Setting the Number of Segments Used (s-no)

• The Number of Segments Used parameter is used to set the number of segments used for the specified program.

• The default is 8.

• Once the number of segments set for the Number of Segments Used parameter have been executed, the program will be in operation completed status. If the setting of the Number of Segments Used parameter is changed to a value smaller than the segment currently being executed in the program, the program will immediately change to operation completed status.

Selecting the Segment to Set (d.seg)

• Set the Display Segment Selection parameter to the number of the segment to set.

Setting Programs Section 3-6

• The setting range is END or 0 to No. of Segments Used −1. The default is END (segment setting completed).

Setting the Segment Set Points and Segment Times (sp) (time)

• For step time programming, each segment has a Segment Set Point parameter and a Segment Time parameter. The number of settings is determined by the Number of Segments Used parameter.

• The setting range for the segment time is 0.00 to 99.59 (h.min or min.s). The default is 0.00.

• Segment 0 is a soak segment. To start from a ramp (increase or decrease), set the segment time for segment 0 to 0 so that actual operation starts from segment 1. (In this example, the Reset Operation parameter is set to stop control.)

3-6-3 Program Setting Example

The following settings are used for the Number of Segments Used and Program No. parameters.

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 pid.

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

Hysteresis (hys) (chys)

• 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.

Operating Procedure Set the hysteresis to 2.0°C.

3-8 Determining the PID Constants (AT or Manual Settings)

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.

• Auto-turning cannot be executed while the program is reset (if the reset operation is set to stop control), while on standby (if the reset operation is set to stop control), during manual operation, and during ON/OFF control.

• The following operations are not possible during auto-tuning: changing settings, holding or releasing the program, and segment operations, such as advance operations.

Operation Level

1. Press the O Key twice to move from the operation level to the adjustment

level.

• Auto-tuning will stop if the Run/Reset parameter is set to Reset and the Reset Operation parameter is set to stop control, or if you switch to manual operation.

• The following operation will be performed if the Reset Operation parameter is set to fixed SP operation.

• If the Run/Reset parameter is changed to Reset during auto-tuning, the present SP will be changed to the fixed SP or the remote SP after autotuning has been completed.

• If auto-tuning is executed while the Run/Reset parameter is set to Reset and the Run/Reset parameter is changed to Run during auto-tuning execution, the program will be started after completing auto-tuning.

• 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 136.

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

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

If you move to the operation level during AT execution, the No. 2 display flashes to indicate that AT is being executed.

Only the following parameters can be changed during auto-tuning: Communications Writing, Run/Reset, and AT Execute/Cancel. Other parameters cannot be changed.

AT Calculated Gain

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

Determining the PID Constants (AT or Manual Settings) Section 3-8

Note PID Constants

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

3-8-2 RT (Robust Tuning)

• When auto-tuning is executed with robust tuning selected, PID constants are automatically set that make it hard for control performance to degenerate even when the characteristics of the controlled object change.

• 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 default 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 auto-tuning is exe-

cuted in normal mode, it is less likely to occur when auto-tuning is executed in RT Mode.

• When the temperature (PV) falls short of the set point for the PID constants when using auto-tuning in normal mode, executing auto-tuning in RT Mode tends to improve performance.

• When the manipulated variable (MV) is saturated, the amount of overshooting may be somewhat higher in comparison to PID control based on auto-tuning in normal mode.

3-9 Alarm Outputs

• Alarms can be used with the E5CN-HT@2@@@ (two auxiliary outputs) or E5AN/EN-HT@2@@@ (two auxiliary outputs). Also, alarms 1 to 3 can be assigned to outputs using the Control Output 1/2 Assignment parameters to use alarms with models that have the following type of control outputs: relay outputs, voltage outputs (for driving SSR). Alarm outputs are determined by a combination of the following alarm output conditions: Alarm Type, Alarm Value, Alarm Hysteresis, and Standby Sequence.

• Alarm outputs are determined by a combination of Alarm Type, Alarm Value, and Alarm Hysteresis alarm output conditions. For details, refer to 4-2-1 Alarm Hysteresis (alh1 to alh3).

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 Using Heater Burnout, Heater Short, and Heater

Overcurrent Alarms

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.

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.

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-HT power. If the heater power is turned ON after turning ON the E5AN-HT power, the HB alarm will be activated.

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

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

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

3-10-2 Installing Current Transformers (CT)

• This function can be used with E5@N-HT models that have the HB alarm, HS alarm, and OC alarm. For the E5CN-HT, connect the CT in advance to terminals 14 and 15 (CT1), or 13 and 15 (CT2). For the E5AN-HT/EN-HT, 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 314.

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

diagram.

Three-phase Heaters (E5@N-HT@@HH@ 3phase 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.

■ Delta connecting lines: Refer to the following diagram for CT installation

positions.

Note Heater voltage fluctuations are not considered here, so be take that

into account when setting the detection current.

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.
