PRECAUTIONS ON SAFETY

 Marks For Ensuring Safe Use and Their Meanings

This manual uses the following marks to indicate precautions for ensuring that the E5AKĆT 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.

NOTICE

Be sure to observe these precautions to ensure safe use.

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

 Never disassemble, repair or modify the product.

 Tighten the terminal screws properly.

 Use the specified size of solderless terminals for wiring.

 Use the product within the rated supply voltage.

 Use the product within the rated load.

 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 expecĆ tancy. If the output relay is used beyond its life expectancy, its contacts may become fused or burned.

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

 Do not cover the E5AKĆT. (Ensure sufficient space around the controller to allow heat radiation.)

 Do not use the controller in the following places:

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

Ă• Places subject vibration and large shocks.

Ă• Places subject to splashing liquid or oil atmosphere.

Ă• Places subject to intense temperature changes.

Ă• Places subject to heat radiation from a furnace.

 Be sure to wire properly with correct polarity of terminals.

 When wiring input or output lines to your controller, keep the following points in mind to reduce the

influence from inductive noise:

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

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

Ă• Using separating pipes, ducts, and shielded line is also useful in protecting the controller, and its

lines from inductive noise.

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

uct.

 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.

 Allow as much space as possible between the controller and devices that generate a powerful high

frequency (highĆfrequency welders, highĆfrequency sewing machines, etc.) or surge. These devices may cause malfunctions.

 If there is a large powerĆgenerating 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.

 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.

 Use within the following temperature and humidity ranges:

Ă• Temperature: Ć10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.

 Store within the following temperature and humidity ranges:

Ă• Temperature: Ć25C to 65C, humidity: 35%RH to 85%RH (with no icing or condensation)

 Never place heavy objects on, or apply pressure to the controller that may cause it to deform and deteĆ

riorate during use or storage.

 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.

Also, of the output functions, control output (heat), control output (cool), HBA and LBA are disabled.

Ă• 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 OperaĆ tion/3.3 Setting Output Specifications (page 3Ć7).

Ă• 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 configuĆ ration is such that heating control output is connected to control output 1, and alarm output is connected to control output 2 and auxiliary outĆ put 1.

Ă• Control outputs 1 and 2 are used depending on the differences in control

method as follows:

Ă• The E5AKĆT supports the following five transfer outputs:

Set point, Process value, Heating side manipulated variable,

Cooling side manipulated variable, Valve opening

However, note that heating/cooling side manipulated variables can be outĆ

put only on standard type controllers, and valve opening can be output

only on positionĆproportional type controllers.

Ă• These transfer outputs can be output after being scaled. Setting of an upĆ

per limit value smaller than the lower limit value is allowed, so reverse scaling can also be carried out.

CHAPTER 1 INTRODUCTION

1.3 Program

JHow programs

are structured

E5AKĆT 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 paĆ

rameters.

Pattern 7

Pattern 1

Pattern 0

Step 0 Step 1 Step 2 Step 15

Ă• Generally, the time setup method" is used to configure programs. By

this method, set points at each step and time are used as program eleĆ ments. 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.

JProgram opera-

tion

F Step operation

F Wait operation

JAlarm output

JProgram output

1–8

Ă• Generally, the target patterns are specified before the program is

executed.

Ă• In parameter setup, you can specify repeated execution of the same patĆ

tern (Repeat) or consecutive execution of all patterns 0 to 7 (Run all).

Ă• During program operation, steps can be skipped (Advance) and the conĆ

trol monitoring can be paused (Hold).

Ă• 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.

Ă• Alarms that are assigned as outputs operate referenced to the alarm valĆ

ues preset to each pattern.

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

output assignment.

Ă• ON/OFF signals are output as time signals according to the timer that

takes a specified step as its start point.

1.4 Parameters and Menus

JParameter types

F Protect mode

F Manual mode

E5AKĆT parameters are distributed between the following ten modes:

Protect mode Manual mode 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 parameĆ

ters, and switching between run and reset operation or auto and manual

operation.

In this mode, the controller can be switched to manual operation. The maĆ

nipulated variable can be manipulated manually only in this mode.

F Level 0 mode

F Program mode

F Level 1 mode

F Level 2 mode

F Setup 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 (autoĆtuning), and set up the control period, PID parameters and heatĆ

er 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 hysterĆ

esis 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.

1–9

CHAPTER 1 INTRODUCTION

F Expansion mode

F Option mode

F Calibration mode

JSelecting 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 programĆ ming, 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. HeatĆ

er burnout alarm function and positionĆproportional 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

(E53ĆAKF) is set in the controller.

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

1.4 Parameters and Menus

Ă• Protected modes cannot be selected. Also, the menu display does not apĆ

pear when modes are protected up to the program mode.

Ă• 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.

Ă• If you select[ĂĂ ] [ĂĂ ] [ĂĂ ] or [ĂĂ ] in the menu display, the

setup, expansion, option and calibration modes, respectively, are seĆ lected. 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.

Ă• To set the controller to the protect mode or to return to the level 0 mode

from the protect mode, press the

neously for 1 second minimum.

Ă• To set the controller to the manual mode, press the key for one seĆ

cond minimum with the 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.

CHAPTER 1 INTRODUCTION

1.5 About the Communications Function

The E5AKĆT can be provided with a communications function that allows

you to check and set controller parameters from a host computer. If the

communications function is required, add on the communications unit.

For details on the communications function, refer to Chapter 6.

F RS-232C

F RS-422

F RS-485

When using the communications function on the RSĆ232C interface, add

on the communications unit (E53ĆAK01).

When using the communications function on the RSĆ422 interface, add on

the communications unit (E53ĆAK02).

When using the communications function on the RSĆ485 interface, add on

the communications unit (E53ĆAK03).

1–12

1.6 About Calibration

The E5AKĆT controller is calibrated before shipment from the factory. So,

the user need not calibrate the E5AKĆT controller during regular use.

However, if the E5AKĆT 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 reĆ

sults of calibration will not be assured.

Also, note that calibration data is updated to the latest value each time

that the E5AKĆT controller is calibrated. Calibration data set before shipĆ

ment from the factory cannot be returned to after calibration by the user.

1.6 About Calibration

F Calibrating

inputs

F Calibrating trans-

fer output

F Registering cal-

ibration data

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

E5AKĆT is provided with the following four calibration parameters:

Ă• Thermocouple

Ă• Platinum resistance thermometer

Ă• Current input

Ă• Voltage input

Two parameters are provided for thermocouple and voltage input.

Transfer output also can be calibrated when the communications unit

(E53ĆAKF) is added on.

When calibrating each item, the calibration data is temporarily regisĆ

tered. This data can be registered as final calibration data only when all

items have been newly calibrated. So, all items must be temporarily regisĆ

tered when the E5AKĆT 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 deĆ

vices and equipment. For details on handling these measuring devices and

equipment, refer to the respective manuals.

For details, see Chapter 7 Calibration.

The descriptions in this chapter follow the order of basic operations shown

in the flow above. Examples of operation of each of the items are described

up to completion of parameter setup. However, you must move to the top

parameter of the following setting. For example, when you have finished

setting input specifications" and you want to set output specifications,"

move to the top parameter of setting output specifications" from the botĆ

tom parameter of setting input specifications."

For details on moving to parameters between items, refer Chapter, SelectĆ

ing modes and Selecting parameters (page 1Ć10).

Ă• A K thermocouple is used as the input.

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

control output 1," control output 2" and auxiliary output 1, respecĆ tively. Of these, only control output 1 and auxiliary output 1 are used.

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

Ă• The upperĆlimit alarm is set as alarm 2. The alarm is output when the

temperature exceeds 10C with respect to the PV.

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

JAnalog input

Ă• 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 reĆ garded as 201.2C after shift when input is 200C before shift.

Ă• To set input shift, set shift values in the input shift upper limit" and inĆ

put shift lower limit" parameters (level 2 mode).

Ă• When the analog input (the voltage input and current input) is selected,

scaling matched to the control is required.

Ă• The scaling upper limit", scaling lower limit" and decimal point" paĆ

rameters (setup mode) are used for scaling. These parameters cannot be used when the temperature input type is selected.

Ă• The scaling upper limit" parameter sets the physical quantity to be exĆ

pressed 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.

Ă• Direct operation" (or normal operation) refers to control where the maĆ

nipulated variable is increased according to the increase in the process valĆ ue. Alternatively, reverse operation" refers to control where the manipuĆ lated 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 manipĆ ulated variable increases by the difference between the PV and SP valĆ ues. Accordingly, this becomes reverse operation" in a heating control sysĆ tem, or alternatively, direct operation" in a cooling control system.

CHAPTER 3 BASIC OPERATION

3.4 Setting Alarm Type

Ă• Three alarm outputs are supported: alarms 1 to 3. Of these, only the

alarm assigned as the output can be used.

Ă• Alarm output conditions are determined according to the combination

of the alarm type", alarm value" and alarm hysteresis" parameter settings.

Ă• The contact conditions for when alarm output is ON can be set to open"

or closed" in the close in alarm/open in alarm" parameter.

Alarm hysteresis

Ă• 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".

Ă• Standby sequence" is a function for unconditionally turning alarm outĆ

put OFF when the process value has left the alarm range once and it next enters the alarm range.

Ă• For example, when the alarm type is set to  lowerĆlimit alarm," generalĆ

ly the process value is within the alarm range, and alarm output smaller than the set point, and alarm output becomes ON when this state continĆ ues. However, if the alarm type is set to  lowerĆlimit alarm with standby sequence", alarm output first becomes ON when the process value exĆ ceeds the alarm setting value to leave the alarm range and once again falls below the alarm value.

Ă• The standby sequence is canceled when an alarm is output. It is, howevĆ

er, 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.

Advance is executed.

JClose in alarm/open in alarm

Ă• When the controller is set to close in alarm," the status of the alarm outĆ

put function is output as it is. When set to open in alarm," the status of the alarm output function is output inverted.

Ă• On a standard type controller, specify the manipulated variable (Ć5.0 to

105.0%) in the MV at reset" parameter (level 2 mode) to output the maĆ nipulated variable during reset. Default is 0.0:0.0%".

Ă• When the controller is reset in the manual mode, the manual MV takes

precedence.

Ă• Both the MV limitter and MV change rate limitter are ineffective against

the manipulated value at reset.

Ă• On a positionĆproportional type controller, you can select either of the

open, closed or hold state. In an open state, only control output 1 is ON. In a closed state, only control output 2 is ON. In a hold state, both control outputs 1 and 2 are OFF. Default is  ".

Using Event Input

On the E53ĆAKB, run/reset can be selected by event input. For details on how to use event input, see 4.8 How to Use Event Input, page 4Ć21.

JManual operation

F Standard type

Ă• On a standard type controller, the manipulated variable is controlled,

and on a positionĆproportional type controller, the valve opening is conĆ trolled.

Ă• To set manual operation and manually set the manipulated variable or

the valve opening, press the key and key simultaneously for 1 second minimum. Then the controllers enters the manual mode. To quit the manual mode, press the key and key again simultaneously for 1 second minimum. The controller enters the level 0 mode without entering the menu display.

Ă• Though the control shifts to manual operation if the controller is set to

the manual mode during program operation, the program advances. When program operation is started in the manual mode, program also advances.

Ă• In the manual mode, the automatic return of display mode does not

work.

Ă• The process value is displayed on the No.1 display, and the manipulated

variable is displayed on the No.2 display.

Ă• To change the manipulated variable, press the or keys. After

two seconds, the manipulated variable is updated to the new setting.

Ă• When switching between manual and auto operation, the manipulated

variable is subject to balanceĆless, bumpĆless operation.

Ă• If the power is interrupted during manual operation, manual operation

is resumed at the manipulated variable that was active at power interĆ ruption when the power is reset.

Ă• AT (autoĆtuning) cannot be executed while operation is reset or during

ON/OFF control.

Ă• When you execute autoĆtuning, the optimum PID parameters are autoĆ

matically set by forcibly changing the manipulated variable to calculate the characteristics (called the limit cycle method") of the control target. During autoĆtuning, time counting is stopped and the AT" LED flashes.

Ă• 40%AT or 100%AT can be selected by the limit cycle of MV change width.

Specify [ ] or [ ], respectively, in the AT execute/cancel" paĆ rameter (level 1 mode).

Ă• During heating and cooling control on a standard type controller, and on

a positionĆproportional type controller, only 100%AT can be executed. (So,  : 40%AT" is not displayed.)

Ă• To cancel AT execution, specify ĂĂĂ : AT cancel".

In order to set the limit cycle of MV change width to 40%, select 40%AT to execute autoĆtuning with fluctuations in the process value kept to a minimum. However, note that autoĆtuning 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% fullĆscale or less.

About PID Parameters

AT Execution Timing

When control characteristics are already known, the PID parameters can be set diĆ rectly 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 5Ć18).

The E5AKĆT differs from fixedĆvalue type controllers in that the SP changes autoĆ matically. So, the timing of AT execution is the most important factor in control. To obtain PID parameters for a specific SP, make a fixedĆvalue program as follows and execute AT.

F Dead band

The dead band is set with the set point as its center. The dead band width is the set value of the dead band" parameter (level 1 mode). Setting a posiĆ tive value produces a dead band, while setting a negative value produces an overlap band. The dead band is factoryĆset to 0.00:0.00%FS."

Ă• In heating and cooling control, the manipulated variable output that is

output when controller operation is stopped is dependent on the set valĆ ue of the MV at reset" parameter (level 2 mode) in the same way as for standard control.

Ă• However, note that in heating and cooling control, the manipulated variĆ

able at the cooling side is treated as a negative value for the sake of conveĆ nience. When the manipulated variable at reset is a negative value, the manipulated variable is output to only the cooling side, and when a posiĆ tive 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.

Ă• On a positionĆproportional type controller, the following functions are

disabled:

F MV limiter

The upperĆ and lowerĆlimit values of the manipulated variable can be reĆ stricted by the MV limitter, and the change rate of manipulated variable can be restricted by the MV change rate limitter.

The upperĆ and lowerĆlimit values of the manipulated variable are set in the MV upper limit" and MV lower limit" parameters (level 2 mode). When the manipulated variable calculated by the E5AKĆT is outside of the range of the MV limitter, actual outputs are dependent on the set value of these parameters.

4.3 Ramp Rise Rate Setup Program

Chapter 3 described programs that used the time setup method." ProĆ

grams were executed using a combination of SPs and step time values. The

E5AKĆT 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 programĆ

ming" parameter (expansion mode) to  : rate of rise."

In a ramp rise rate program, parameters are set to two steps as shown in

the figure above. The following figure shows the relationship between the

F When the rate of

When the number of steps is set to an odd number, the final soak time canĆ

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 rate of rise 0 to 7" parameter is set to 0", the ramp step is skipped

and the soak step appears to be continuous.

Target SP 0 : 100 Rate of rise 0 : 3 Soak time 0 : 0.30

“Number of steps” = 4, “Time unit of ramp rate” = minutes, “PV start” = 10

Target SP 1 : 10 Rate of rise 1 : 3 Soak time 1 : 0.30

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.

(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

(100Ć10/3=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 minĆ

utes using the same formula.

(3) In step 1, the Present SP does not change, and the step time is the valĆ

ue 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 valĆ

ue set to the soak time 1" parameter (in this example, 30 minutes").

counting is paused (Hold), and the HOLD" LED lights.  " and the SP appear alternately on the No.2 display when in the PV/Present SP" parameter.

Ă• Hold is canceled time and counting is restarted by one of the following

conditions: hold" parameter =  : OFF", Run, Reset, End operation using advance instruction

Ă• Each time that advance" parameter (level 0 mode) is set to  : ON",

the program advances one step. With each step advance, the Advance" parameter setting returns to  : OFF".

Ă• If the advance function is executed with the program in a hold state, the

hold state is continued in the next step.

4.9 How to Use the Heater Burnout Alarm

Ă• 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.

Ă• When using the HBA function, assign output function heater burnout

alarm" to control outputs 1/2 or auxiliary outputs 1/2.

JHeater burnout

detection

To E5AK CT terminal

Heater wire

F HBA

latch/release

Ă• 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 generĆ

ates AC current proportional to the current value. The E5AK meaĆ

sures this AC current to calculate the current flowing to the heater.

(3) If the heater is burned out, the current measured at the current transĆ

former decreases. This value is compared with the value set as the

heater burnout set value and is output as the heater burnout alarm.

Ă• Set the heater burnout set value in the heater burnout alarm" parameĆ

ter. To verify the current value of the current transformer, use the heatĆ er current monitor" parameter.

Ă• When you are not using the HBA function, set the heater burnout

alarm" parameter to 0.0 (disabled)".

Ă• 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.)

Ă• To enable the HBA latch function, set the HBA latch" parameter to

ON".

JOperating

conditions

Ă• Turn the heater power supply ON at the same time as or before turning

the E5AKĆT power supply ON. If the heater power supply is turned ON after turning the E5AKĆT power supply ON, the heater burnout alarm is output.

Ă• 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.)

Ă• The heater burnout alarm is detected only if the control output is continĆ

uously ON for 190 ms minimum.

Ă• 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.

Ă• 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 miniĆ mum.

4–23

CHAPTER 4 APPLIED OPERATION

Ă• 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 3Ćphase heatĆ ers.

To detect heater burnout on a 3Ćphase heater, use the K2CUĆFAĆGS (with gate input terminal). (For details, see the respective product catalog.)

JHow to calculate

the heater burnout set value

Ă• Calculate the set value by the following formula:

Set value =

Ă• Set the current value at burnout when two or more heaters are conĆ

nected to the CT to the value at the time that the heater having the smallĆ er(est) current value burns out (the value when one of the heaters burns out with all heaters at the same current).

Ă• Make sure that the following condition is satisfied:

Heater of current 10.0 A or less Current value at normal operation Ć current value at heater burnĆ out y 1A When resultant current is less than 1 A, detection is unstable.

Heater of current 10.0 A minimum Current value at normal operation Ć current value at heater burnĆ out y 2.5 A When resultant current is less than 2.5 A, detection is unstable.

Ă• 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."

Ă• 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.

4.10 LBA

Ă• The LBA (Loop Break Alarm) function can be used only on standard

type controllers.

Ă• 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 conĆ verter error results.

Ă• LBA (Loop Break Alarm) is a function for judging that an error has ocĆ

curred 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.

F LBA detection

F LBA detection

F LBA detection

example

Ă• Normally, when output is set to maximum or minimum, the process valĆ

ue rises or falls after the dead time has elapsed. LBA is output if the proĆ cess 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."

Ă• 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.

Ă• The following example describes what happens when a heater burnout

occurs at maximum output.

LBA=ON

4–26

Ă• 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 changĆ ing greatly at the 1st judgment time band, so LBA remains OFF.

Ă• 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.

Ă• 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.

F Setting the LBA

detection time

F Determining the

LBA detection time

Ă• The LBA detection time is automatically set by autoĆtuning (except in

heating and cooling control).

Ă• If the optimum LBA detection time cannot be obtained by autoĆtuning,

set the time in the LBA detection time" parameter (level 2 mode).

Ă• 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).

Measurement time Tm
