Marks For Ensuring Safe Use and Their Meanings

This manual uses the following marks to indicate precautions for ensuring that the

E5AK-T is used safely.

The precautions indicated below describe important information regarding safety.

Be sure to follow the instructions described in these precautions.

WARNING

Incorrect handling may cause death or injury.

WARNING

Do not touch the terminals while the power is

ON.

This may cause an electric shock.

IV

E5AK

NOTICE

Be sure to observe these precautions to ensure safe use.

F

Do not use the product in places where explosive or flammable gases may be present.

F

Never disassemble, repair or modify the product.

F

Tighten the terminal screws properly.

F

Use the specified size of solderless terminals for wiring.

F

Use the product within the rated supply voltage.

F

Use the product within the rated load.

F

The life expectancy of the output relay varies considerably according to its switching capacity and operating conditions. Be sure to use the output relay within its rated load and electrical life expectancy. If the output relay is used beyond its life expectancy, its contacts may become fused or burned.

F

If you remove the controller from its case, never touch nor apply shock to the electronic parts inside.

F

Do not cover the E5AK-T. (Ensure sufficient space around the controller to allow heat radiation.)

F

Do not use the controller in the following places:

• Places subject to icing, condensation, dust, corrosive gas (especially sulfide gas or ammonia gas).

• Places subject vibration and large shocks.

• Places subject to splashing liquid or oil atmosphere.

• Places subject to intense temperature changes.

• Places subject to heat radiation from a furnace.

F

Be sure to wire properly with correct polarity of terminals.

F

When wiring input or output lines to your controller, keep the following points in mind to reduce the influence from inductive noise:

• Allow adequate space between the high voltage/current power lines and the input/output lines.

• Avoid parallel or common wiring with high voltage sources and power lines carrying large currents.

• Using separating pipes, ducts, and shielded line is also useful in protecting the controller, and its lines from inductive noise.

F

Cleaning: Do not use paint thinner or organic solvents. Use standard grade alcohol to clean the product.

F

Use a voltage (100 to 240 VAC at 50 to 60 Hz). At power ON, the prescribed voltage level must be attained within two seconds.

F

Allow as much space as possible between the controller and devices that generate a powerful high frequency (high-frequency welders, high-frequency sewing machines, etc.) or surge. These devices may cause malfunctions.

F

If there is a large power-generating peripheral device and any of its lines near the controller, attach a surge suppressor or noise filter to the device to stop the noise affecting the controller system. In particular, motors, transformers, solenoids and magnetic coils have an inductance component, and therefore can generate very strong noise.

F

When mounting a noise filter on the power supply to the controller, be sure to first check the filter’s voltage and current capacity, and then mount the filter as close as possible to the controller.

V

E5AK

F

Use within the following temperature and humidity ranges:

• Temperature: -10_C to 55_C, humidity: 35%RH to 85%RH (with no icing or condensation)

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.

If the controller is subjected to heat radiation, use a fan to cool the surface of the controller to under 55_C.

F

Store within the following temperature and humidity ranges:

• Temperature: -25_C to 65_C, humidity: 35%RH to 85%RH (with no icing or condensation)

F

Never place heavy objects on, or apply pressure to the controller that may cause it to deform and deteriorate during use or storage.

F

Avoid using the controller in places near a radio, television set, or wireless installation. These devices can cause radio disturbances which adversely affect the performance of the controller.

Add on the input unit (E53-CKB) when using event input. You can select from the following six event inputs:

Run/Reset, Remote/Local, Auto/Manual, Hold/Hold Cancel, Advance,

Pattern

The output functions of the E5AK-T do not operate for five seconds after the

E5AK-T is turned ON.

The E5AK-T supports the following five outputs:

Control output 1

Control output 2

Auxiliary output 1

Auxiliary output 2

Transfer output

When using control output 1 and 2, set the output unit (sold separately). Nine output units are available to suit the output circuit configuration.

When using transfer output, add on the communication unit

(E53-AKF).

• The E5AK-T supports the following thirteen output functions:

Control output (heat), Control output (cool), Alarms 1 to 3, HBA,

LBA, Time Signals 1 and 2, Program End, Stage Output,

Error 1 (input error), Error 2 (A/D converter error)

• Assign these output functions to control output 1, control output 2, auxiliary output 1, and auxiliary output 2.

However, note that as control output 1 is used as the open output and control output 2 is used as close output on a position-proportional type controller (E5AK-TPRR2), control outputs 1 and 2 cannot be used as assignment destinations. Also, of the output functions, control output (heat), control output (cool), HBA and LBA are disabled.

• On a standard type controller, there are restrictions on how assignment destinations (control output 1, control output 2, auxiliary output 1, and auxiliary output 2) can be used. For details, see Chapter 3

Basic Operation/3.3 Setting Output Specifications (page 3-7).

• In the example on the previous page, “control output (heat)” is assigned to “control output 1”, “alarm 1” is assigned to “control output

2”, and “alarm 2” is assigned to “auxiliary output 1”. Accordingly, the configuration is such that heating control output is connected to control output 1, and alarm output is connected to control output 2 and auxiliary output 1.

• Control outputs 1 and 2 are used depending on the differences in control method as follows:

Cooling side manipulated variable, Valve opening

However, note that heating/cooling side manipulated variables can be output only on standard type controllers, and valve opening can be output only on position-proportional type controllers.

• These transfer outputs can be output after being scaled. Setting of an upper limit value smaller than the lower limit value is allowed, so reverse scaling can also be carried out.

CHAPTER 1 INTRODUCTION

1.3 Program

J

How programs are structured

E5AK-T allows you to configure programs made up of a maximum of eight patterns (pattern 0 to 7).

The number of steps (16 maximum) in each pattern can be specified in parameters.

Pattern 7

Pattern 1

Pattern 0

Step 0 Step 1 Step 2 Step 15

• Generally, the “time setup method” is used to configure programs. By this method, set points at each step and time are used as program elements. However, the “ramp rise rate setup method” can also be used.

By this method, the set point, ramp time and soak times are used as program elements.

J

Program operation

• Generally, the target patterns are specified before the program is executed.

• In parameter setup, you can specify repeated execution of the same pattern (Repeat) or consecutive execution of all patterns 0 to 7 (Run all).

F

Step operation

• During program operation, steps can be skipped (Advance) and the control monitoring can be paused (Hold).

F

Wait operation

• When the wait width is specified in parameter setup, the program does not go to the next step and waits until the PV reaches the specified time (wait width) at the end of each step.

J

Alarm output

• Alarms that are assigned as outputs operate referenced to the alarm values preset to each pattern.

J

Program output

• Time signals, program end and stage output can be output according to output assignment.

• ON/OFF signals are output as time signals according to the timer that takes a specified step as its start point.

Level 0 mode

Program mode

Level 1 mode

Level 2 mode

Setup mode

Expansion mode

Option mode

Calibration mode

The settings of parameters in each of eight modes (excluding the protect mode and manual mode) can be checked and modified by selection on the menu display.

The protect function is for preventing unwanted modification of parameters, and switching between run and reset operation or auto and manual operation.

In this mode, the controller can be switched to manual operation. The manipulated variable can be manipulated manually only in this mode.

Set the controller to this mode during normal operation. In this mode, you can change the set point and pattern during operation, and execute step operation (e.g. advance). You can only monitor (not change) the process value, step No., standby time, pattern elapsing time, pattern execution count and manipulated variable.

This is the programming mode. In this mode, you can set the number of steps used in each pattern, pattern execution count, alarm values, set points for each step, step time, and time signals for two steps.

This is the main mode for adjusting control. In this mode, you can execute AT (auto-tuning), and set up the control period, PID parameters and heater burnout alarm (HBA) conditions.

This is the auxiliary mode for adjusting control. In this mode, you can set the parameters for limiting the manipulated variable, switch between the remote and local modes, and set the loop break alarm (LBA), alarm hysteresis and the digital filter value of inputs.

This is the mode for setting the basic specifications. In this mode, you can set parameters that must be checked or set before operation such as the input type, scaling, output assignments and direct/reverse operation.

Selecting modes

This is the mode for setting expanded functions. In this mode, you can set SP setting limitter, switching between advanced PID control or ON/

OFF control, program time unit, selection of step time/rate of rise programming, time unit of ramp rise rate, and the time for automatic return to the monitoring display.

This is the mode for setting optional functions. You can select this mode only when an option unit is mounted in the controller. In this mode, you can set the communications conditions, transfer output and event input parameters to match the type of option unit mount in the controller. Heater burnout alarm function and position-proportional travel time are also located in this mode.

This mode is provided so that the user can calibrate inputs and output.

When calibrating input, the selected input type is calibrated. Whereas, transfer output can be calibrated only when the communication unit

(E53-AKF) is set in the controller.

The following diagram shows the order in which modes are selected.

Selecting parameters

1.4 Parameters and Menus

• Protected modes cannot be selected. Also, the menu display does not appear when modes are protected up to the program mode.

• If you select [

], [ ], [ ] or [ ] in the menu display, the level 0, program, level 1 and level 2 modes, respectively, are selected.

These modes are selected with control still continuing.

• If you select[

] [ ] [ ] or [ ] in the menu display, the setup, expansion, option and calibration modes, respectively, are selected.

When these modes are selected, the control is reset. So, control outputs and auxiliary output are turned OFF. When another mode is selected while in these modes control, reset is canceled.

• To set the controller to the protect mode or to return to the level 0 mode from the protect mode, press the

RUN/RST key and the key simultaneously for 1 second minimum.

• To set the controller to the manual mode, press the second minimum with the key for one key held down in the level 0 to 2 modes. To return to the level 0 mode in the manual mode, press the key for one second minimum with the key pressed. Be sure to press the key first in this operation.

• When the controller is not in the manual mode, each press of the key switches the parameter in the respective mode.

Fixing settings

• If you press the key when at the final parameter, the display returns to the top parameter for the current mode.

• When you change parameter settings or contents, specify the parameter using the or keys, and either leave the setting for at least two seconds or press the key. This fixes the setting.

• When another mode is selected, the content of the parameters before the mode was selected is fixed.

• When you turn the power OFF, you must first fix the settings and parameter contents (by pressing the key or selecting another mode). The settings and parameter contents are sometimes not changed by merely pressing the or keys.

1.6 About Calibration

1.6 About Calibration

F

Calibrating inputs

The E5AK-T controller is calibrated before shipment from the factory.

So, the user need not calibrate the E5AK-T controller during regular use.

However, if the E5AK-T controller must be calibrated by the user, use the parameters provided for the user to calibrate temperature input, analog input (voltage, current) and transfer output. In this case, note that the results of calibration will not be assured.

Also, note that calibration data is updated to the latest value each time that the E5AK-T controller is calibrated. Calibration data set before shipment from the factory cannot be returned to after calibration by the user.

The input type selected in parameters is the item to be calibrated. The

E5AK-T is provided with the following four calibration parameters:

• Thermocouple

• Platinum resistance thermometer

• Current input

• Voltage input

Two parameters are provided for thermocouple and voltage input.

F

Calibrating transfer output

Transfer output also can be calibrated when the communications unit

(E53-AKF) is added on.

F

Registering calibration data

When calibrating each item, the calibration data is temporarily registered. This data can be registered as final calibration data only when all items have been newly calibrated. So, all items must be temporarily registered when the E5AK-T controller is calibrated.

When registering data, information regarding whether or not calibration has been carried out is also registered.

To calibrate these items, the user must prepare separate measuring devices and equipment. For details on handling these measuring devices and equipment, refer to the respective manuals.

For details, see Chapter 7 Calibration.

Draw-out

• On a standard type controller, set up the output units for control outputs 1 and 2 before mounting the controller.

• On a position-proportional type controller, the relay output unit is already mounted. So, this setup operation is unnecessary. (That is, do not replace the currently mounted unit with other output units.)

• When setting up the output units, draw out the internal mechanism from the housing, and insert the output units into the sockets for control outputs 1 and 2.

When drawing out the internal mechanism from the housing, prepare a

Phillips screwdriver matched to the size of the screw on the lower part of the front panel.

(1) Press down on the hook on the top of the front panel, and turn the

Phillips screwdriver to the left to loosen the screw on the lower part of the front panel.

This description assumes that the controller is operated under the following conditions.

• A K thermocouple is used as the input.

• Control output (heat), alarm 1 and alarm 2 functions are assigned to

“control output 1,” “control output 2” and auxiliary output 1, respectively. Of these, only control output 1 and auxiliary output 1 are used.

• The relay output unit is mounted at control output 1.

• The upper-limit alarm is set as alarm 2. The alarm is output when the temperature exceeds 10_C with respect to the PV.

• The program is made up of one pattern comprising four steps.

• When input is temperature input, the upper and lower limit values of the sensor can be shifted linearly. For example, if both the upper and lower limit values are shifted by 1.2_C, the process value (before shift) is regarded as 201.2_C after shift when input is 200_C before shift.

• To set input shift, set shift values in the “input shift upper limit” and

“input shift lower limit” parameters (level 2 mode).

• When the analog input (the voltage input and current input) is selected, scaling matched to the control is required.

• The “scaling upper limit”, “scaling lower limit” and “decimal point” parameters (setup mode) are used for scaling. These parameters cannot be used when the temperature input type is selected.

• The “scaling upper limit” parameter sets the physical quantity to be expressed by the upper limit value of input, and the “scaling lower limit” parameter sets the physical quantity to be expressed by the lower limit value of input. The “decimal point” parameter sets the number of digits past the decimal point.

• The following figure shows a scaling example of 4 to 20 mA input. After scaling, the humidity can be directly read. In this case, the “decimal point” parameter is set to “1”.

• “Direct operation” (or normal operation) refers to control where the manipulated variable is increased according to the increase in the process value. Alternatively, “reverse operation” refers to control where the manipulated variable is decreased according to the decrease in the process value.

For example, when the process value (PV) (temperature), is lower than the set point (SP) (temperature), in a heating control system, the manipulated variable increases by the difference between the PV and

SP values.

Accordingly, this becomes “reverse operation” in a heating control system, or alternatively, “direct operation” in a cooling control system.

• Direct/reverse operation is set in the “direct/reverse operation” parameter (setup mode). Default is “ : reverse operation”.

• On position-proportional type controllers, this item cannot be set.

• On a standard type controller, when the output unit is for pulse output such as relay output, set the pulse output cycle (control period).

Though a shorter control period provides better control performance, the control period should be set to 20 seconds minimum taking the life expectancy of the output unit into consideration when the output unit is for relay output.

• The control period is set in the “control period (heat)” parameter

(level 1 mode). Default of the “control period” parameter is factoryset to “20:20 seconds.” The “control period (cool)” output function is not assigned. So, the “control period (cool)” parameter cannot be set.

Alarm value Alarm value

• Alarm hysteresis is set independently for each alarm in the “alarm 1 to 3 hysteresis” parameters (level 2 mode). Default is “0.02:

0.02%FS”.

• “Standby sequence” is a function for unconditionally turning alarm output OFF when the process value has left the alarm range once and it next enters the alarm range.

• For example, when the alarm type is set to “ lower-limit alarm,” generally the process value is within the alarm range, and alarm output smaller than the set point, and alarm output becomes ON when this state continues. However, if the alarm type is set to “ lower-limit alarm with standby sequence”, alarm output first becomes ON when the process value exceeds the alarm setting value to leave the alarm range and once again falls below the alarm value.

• The standby sequence is canceled when an alarm is output. It is, however, restarted later by one of the following conditions:

Operation is started or power is turned ON.

A pattern is started.

The program advances to the next step.

The SP of the current step is changed.

The currently running alarm value is changed.

The input shift value is changed.

Set point

Deviation at start of AT execution ≧ 10% FS

• AT (auto-tuning) cannot be executed while operation is reset or during ON/OFF control.

• When you execute auto-tuning, the optimum PID parameters are automatically set by forcibly changing the manipulated variable to calculate the characteristics (called the “limit cycle method”) of the control target. During auto-tuning, time counting is stopped and the

“AT” LED flashes.

• 40%AT or 100%AT can be selected by the limit cycle of MV change width. Specify [ ] or [ ], respectively, in the “AT execute/ cancel” parameter (level 1 mode).

• During heating and cooling control on a standard type controller, and on a position-proportional type controller, only 100%AT can be executed. (So, “ : 40%AT” is not displayed.)

• To cancel AT execution, specify “

: AT cancel”.

In order to set the limit cycle of MV change width to 40%, select 40%AT to execute auto-tuning with fluctuations in the process value kept to a minimum. However, note that auto-tuning takes longer to execute compared with 100%AT.

The timing by which limit cycles are generated varies according to whether or not the deviation (DV) at the start of AT execution is 10% full-scale or less.

About PID Parameters

AT Execution Timing

When control characteristics are already known, the PID parameters can be set directly to adjust control.

PID parameters are set in the “proportional band” (P), “integrated time” (I) and

“derivative time” (D) parameters (level 1 mode).

For details on the setting ranges of these parameters, see chapter 5 Level 1 Mode

(page 5-18).

The E5AK-T differs from fixed-value type controllers in that the SP changes automatically. So, the timing of AT execution is the most important factor in control.

To obtain PID parameters for a specific SP, make a fixed-value program as follows and execute AT.

When the manipulated variable at reset is a negative value, the manipulated variable is output to only the cooling side, and when a positive value, the manipulated variable is output to only the heating side.

Default is “0”. If the controller is operated with default, the manipulated variable is not output to both the heating and cooling sides.

4.3 Ramp Rise Rate Setup Program

4.3 Ramp Rise Rate Setup Program

Chapter 3 described programs that used the “time setup method.” Programs were executed using a combination of SPs and step time values.

The E5AK-T also supports the “ramp rise rate setup method.” By this method, programs are executed using three program elements: “target

SP”, “rate of rise” and “soak time.”

To select a ramp rise rate program, set the “Step time/rate of rise programming” parameter (expansion mode) to “ : rate of rise.”

Relationship with the number of steps

When the number of steps is set to an odd number, the final soak time cannot be set. For example, if we set the “number of steps” parameter to “7”, the “soak time 3” parameter cannot be set even though the “target SP 3” and “rate of rise 3” parameters can be set.

Accordingly, when the number of steps are set to an even number, the final step is a soak step. When it is set to an odd number, the final step is a ramp step.

Number of steps = even number Number of steps = odd number

When the rate of rise is set to “0”

F

Program structure

In a program comprising four steps, steps 0 and 1 follow the settings of the “target SP 0”, “rate of rise 0” and “soak time 0” parameters. Steps 2 and 3 follow the settings of the “target SP 1”, “rate of rise 1” and “soak time 1” parameters.

F

How the program works

(1) As the program starts at PV (PV start), the program starts operation from “10” in this example.

(2) As the rate of rise is set to “3”, the Present SP takes 30 minutes

(100-10/3=30) to reach the target SP value “100” in step 0. If the

PV is “40” when the program is started, this time then becomes 20 minutes using the same formula.

(3) In step 1, the Present SP does not change, and the step time is the value set to the “soak time 0” parameter (in this example, “30 minutes”).

(4) In step2, the Present SP changes according to the value of “rate of rise 1” parameter from that of “target SP 0” parameter to that of

“target SP 1” parameter. It takes 30 minutes in this example.

(5) In step 3, the Present SP does not change, and the step time is the value set to the “soak time 1” parameter (in this example, “30 minutes”).

• Set the step at which to output the time signal in the “time signal 1/2 enabled step” parameter (program mode). (Default is “0: step 0.”)

• Set the ON/OFF timing in the “time signal 1/2 ON time” and “time signal OFF time” parameters (program mode).

• When the OFF time is set shorter than the ON time, output is ON until a reset from the ON time elapsed point onwards or at start of the next pattern.

• Output does not turn ON when ON and OFF times are set the same.

• When step advance is executed during execution of the time signal enabled step, the controller judges that the time equivalent to the enabled step has elapsed. For example, in the above figure, output is ON from the start of the following step up to the OFF time elapsed point.

You can verify the pattern elapsing time in the “pattern elapsing time” parameter (level 0 mode). During repeated execution of patterns or run all execution, the program is counting for each pattern.

If the count exceeds the monitor range (99 hours:59 minutes or 99 minutes:59 seconds), “99.59” is displayed flashing.

During Hold, time counting is paused.

Remote/Local

• This function is supported only when E53-AK01/02/03, the option unit for serial communications, is installed.

• Remote/local cannot be assigned in the “event input assignment 1/2” parameters.

• When event input is set to “ON”, parameters can be written only by using the communications function, and the “RMT” LED lights. The content of event input is reflected in the “remote/local” parameter

(level 2 mode).

• Remote/local can be switched up to 100,000 times.

Operating

conditions

• On a standard type controller, the HBA (heater burnout alarm) function can be used only when the assignment destination of the output function “control output (heat)” is set to pulsed output.

• When using the HBA function, assign output function “heater burnout alarm” to control outputs 1/2 or auxiliary outputs 1/2.

• Heater burnout detection works as follows:

(1) Connect the current transformer (CT) to terminal Nos.15 and 17, and insert the heater lead through the CT hole.

(2) When current flows through this lead, the current transformer generates AC current proportional to the current value. The E5AK measures this AC current to calculate the current flowing to the heater.

(3) If the heater is burned out, the current measured at the current transformer decreases. This value is compared with the value set as the heater burnout set value and is output as the heater burnout alarm.

• Set the heater burnout set value in the “heater burnout alarm” parameter. To verify the current value of the current transformer, use the “heater current monitor” parameter.

• When you are not using the HBA function, set the “heater burnout alarm” parameter to “0.0 (disabled)”.

• When the HBA latch function is set to “ON”, the heater burnout alarm is held until either of the following measures is taken: a Set the heater burnout set value to “0.0A” (default).

b Reset the controller.

(Turn the controller’s power OFF then back ON again.)

• To enable the HBA latch function, set the “HBA latch” parameter to

“ON”.

• Turn the heater power supply ON at the same time as or before turning the E5AK-T power supply ON. If the heater power supply is turned ON after turning the E5AK-T power supply ON, the heater burnout alarm is output.

• Control is continued even when the heater burnout alarm is output.

(That is, the controller attempts to control the heater as if the heater burnout alarm has not occurred.)

• The heater burnout alarm is detected only if the control output is continuously ON for 190 ms minimum.

• The rated current value may sometimes differ slightly from the actual current value flowing to the heater. Verify the current value in an actual operating state in the “heater current monitor” parameter.

• If there is little difference between the current in a normal state and the current in a burnout state, detection may become unstable. On a heater of current 10.0 A or less, maintain a difference of 1.0 A minimum. On a heater of current 10.0 A minimum, maintain a difference of 2.5 A minimum.

4--23

E5AK

CHAPTER 4 APPLIED OPERATION

• The heater burnout alarm function cannot be used when the heater is controlled by a phase control system or by a cycle control system.

Also, the heater burnout alarm function cannot be applied on 3-phase heaters.

To detect heater burnout on a 3-phase heater, use the K2CU-FjjA-jGS (with gate input terminal). (For details, see the respective product catalog.)

J

How to calculate the heater burnout set value

• Calculate the set value by the following formula:

Set value =

(current value at normal operation + current value at burnout)

2

• Set the current value at burnout when two or more heaters are connected to the CT to the value at the time that the heater having the smaller(est) current value burns out (the value when one of the heaters burns out with all heaters at the same current).

• Make sure that the following condition is satisfied:

Heater of current 10.0 A or less

Current value at normal operation - current value at heater burnout ≧ 1A

When resultant current is less than 1 A, detection is unstable.

Heater of current 10.0 A minimum

Current value at normal operation - current value at heater burnout ≧ 2.5 A

When resultant current is less than 2.5 A, detection is unstable.

• The set value can be set within the range 0.1 to 49.9 A. Heater burnout is not detected when the setting is “0.0” or “50.0”. When the setting is “0.0”, the heater burnout alarm is set to “OFF,” and when the setting is “50.0”, the heater burnout alarm is set to “ON.”

• Set the total current value at normal heater operation to 50 A or less.

When set to 55.0 A minimum, [ ] is displayed in the “heater current monitor” parameter.

LBA detection time

LBA detection width

F

LBA detection example

• The LBA (Loop Break Alarm) function can be used only on standard type controllers.

• The LBA function can be used only when it is assigned as an output.

Also, the LBA function does not work when a memory error or A/D converter error results.

• LBA (Loop Break Alarm) is a function for judging that an error has occurred somewhere on the control loop and for outputting an alarm when the process value does not change with the manipulated variable at a maximum or minimum state. Accordingly, the LBA function can be used as a means for detecting a malfunctioning control loop.

• Normally, when output is set to maximum or minimum, the process value rises or falls after the dead time has elapsed. LBA is output if the process value does not change in the predicted direction after a fixed amount of time has elapsed. This fixed amount of time is the

“LBA detection time.”

• LBA operation sometimes becomes unstable when the process value fluctuates considerably due to the control characteristics. The LBA detection width is provided so that changes with respect to output can be correctly detected. Changes smaller than the detection width due to LBA detection timing are not regarded as changes.

• The following example describes what happens when a heater burnout occurs at maximum output.

LBA detection time LBA detection time

PV

LBA detection width

Output

Time

Heater burnout LBA=ON

• LBA judgment is carried out at each LBA detection time from the point of maximum output. In the above figure, the process value (PV) is changing greatly at the 1st judgment time band, so LBA remains

OFF.

• At the 2nd judgment time band, the process value increases as indicated by the broken line if the process value is normal. This means that the change width exceeds the LBA detection width, and LBA output remains OFF.

• If the heater burns out at the point shown in the above figure, the process value “decreases.” Accordingly, it is judged that “the process value is not changing in the increasing direction” at the 2nd judgment time band and the LBA output becomes ON.

Setting the LBA detection time

• The LBA detection time is automatically set by auto-tuning (except in heating and cooling control).

• If the optimum LBA detection time cannot be obtained by auto-tuning, set the time in the “LBA detection time” parameter (level 2 mode).

F

Determining the

LBA detection time

• Calculate the LBA detection time as follows:

(1) Set output to maximum.

(2) Measure the time it takes for the input change width to reach the

LBA detection width (factory setting: 0.2% FS).

4.11 How to Use Transfer Output

• When using transfer output, add on the communications unit

(E53-AKF).

F

Transfer output type

• You can select the following five data items in the “transfer output type” parameter (option mode) as the transfer outputs:

Present SP (default), Process value, Manipulated variable (heat),

Manipulated variable (cool), Valve opening

However, note that heating/cooling side manipulated variables can be output only on standard type controllers, and valve opening can be output on position-proportional type controllers.

• If the output assignment is changed when either the “manipulated variable (heat)” or “manipulated variable (cool)” parameter is selected, the factory setting “set point” is returned to.

F

Transfer output scaling

• These transfer outputs can be scaled according to the settings of the

“transfer output upper limit” and “transfer output lower limit” parameters before output. Setting of an upper limit value smaller than the lower limit value is allowed, so reverse scaling can also be carried out. Also, the scale can be enlarged by the upper- and lower-limit width specified for each data item. The following example shows scaling of the heating side manipulated variable.

Conditions of Use

The control must be advanced PID control.

• The “MV upper limit” and “MV lower limit” parameters set the upper and lower limits of the manipulated variable. When the manipulated variable calculated by the E5AK-T controller strays from the upper- and lower-limit range, the upper limit or lower limit set to these parameters is output, respectively. However, note that these parameters are disabled during position-proportional control.

• The “MV change rate limit” parameter sets the maximum permissible change width per second of the manipulated variable (on the position-proportional control, valve opening). If a change in the manipulated variable (on the position-proportional control, valve opening) causes this parameter setting to be exceeded, the calculated value is reached while changing the value by the per-second value set in this parameter.

This function is disabled when the set value is “0.0”.

CHAPTER 6 USING THE COMMUNICATIONS FUNCTION

6.1 Outline of the Communications Function

J

Outline

The communications function allows you to monitor and set E5AK-T parameters by a program prepared and running on a host computer connected to the E5AK-T controller. This chapter describes operations as viewed from the host computer.

When the communications function is used, the E53-AK01/02/03 communications unit must be added on.

The E5AK-T communications function allows you to carry out the following:

• Read/write parameters

• Instruct operations

• Select the setting level.

The communications function assumes the following conditions:

• Writing of parameters is possible only during remote operation. Also, parameters cannot be written during execution of auto-tuning.

• Writing of parameters is limited by setting level. Writing conditions are as follows depending on the setting level:

• Setting level 1: No restrictions

• Setting level 0: Writing of parameters in the setup, expansion and option modes only is prohibited.

• The “remote/local”, “AT execute/cancel”, “hold/hold cancel” and

“advance” parameters are set aside from other parameters as special commands for instructing operations.

J

Transfer procedure

Host computer

E5AK-T

The host computer sends a “command frame” to the controller, and the controller returns a “response frame” corresponding to the content of the command sent by the host computer. In other words, a response frame is returned for each command frame sent.

The following diagram shows command frame/response frame operations.

The following functions are issued as special commands.

• Run/Reset

Runs or stops programs. This command cannot be issued in setting level 1.

• Remote/Local (maximum number of writes: 100,000)

Selects remote operation or local operation.

• AT Execute/Cancel

Executes or cancels auto-tuning. This command cannot be issued in setting level 1.

• Move to setting level 1

Issue this command when writing parameters in the setup, expansion and option modes. On the E5AK-T, the parameter switches to the top parameter

: input type” of the setup mode, and control is stopped.

• Software reset

Resets E5AK-T operation (same as turning power ON) by communications. A response is not returned to this command. Also, communications with the E5AK-T cannot be carried out for five seconds after reset.

• Status

Monitors the status of the E5AK-T. Two command groups are available, A and B, depending on the instruction code. The response is returned in bit units to the instruction code (4B) of the response frame.

For details on the monitoring details of each group, see page 6-11.

• Hold

Holds program execution or cancels hold. This command cannot be issued in setting level 1.

• Advance

Advances execution of steps in the program. This command cannot be issued in setting level 1.

Storage of calibration data

If the E5AK-T controller does not support the transfer output function, calibration of transfer output is automatically deleted from the calibration procedure as follows:

Calibration of inputs → Storage of calibration data

• Only inputs that have been set in the “input type” parameter (setup mode) can be calibrated. To temporarily store data for each of the calibration parameters, press the key for 1 second.

• Transfer output can be calibrated only when the Communications unit (E53-AKF) is set in the controller. To adjust data items, press the or keys.

• The data store menu is displayed only when all calibration items have temporarily been stored.

• After calibrating input, you must always check indication accuracy.

• LBA (Loop Break Alarm) can be used as a means for detecting loop breaks when the control loop is not functioning normally. For details, see page 4-26.

• LBA allows you to detect the following errors:

(1) Heater burnout (HBA)

(2) Output error (contact weld, damaged transistors, etc.)

(3) Sensor error (constant input values, etc.)

• If you use the LBA function, set the loop break detection time matched to the control characteristics in the “LBA detection time” parameter (level 2 mode).

• If you assign error 1 as the output, an error can be output to auxiliary output 1 or auxiliary output 2 when input is in error. When this error occurs, remedy by following the description for “Input error”.

• If you assign error 2 as the output, an error can be output to auxiliary output 1 or auxiliary output 2 when the A/D converter is in error.

When this error occurs, remedy by following the description for “A/D converter error”.
