If malfunction prevents control, this may result in a major accident. D Use a screwdriver or similar tool to remove the output unit if it is hard to remove.

If you attempt to remove it by applying excessive force, you may be injured by pointed pins.

NOTICE

Be sure to observe these precautions to ensure safe use.

(1) Do not wire the terminals which are not used. (2) Be sure to wire properly with correct polarity of terminals. (3) To reduce induction noise, separate the high-voltage or large-current power lines from other

lines, and avoid parallel or common wiring with the power lines when you are wiring to the terminals. We recommend to use separating pipes, ducts, or shielded lines.

(4) Do not use this product in the following places:

• P laces subject to dust or corrosive gases (in particular, sulfide gas and ammonia gas)

• Places subject to high humidity, condensation or freezing.

• Places subject to direct sunlight.

• P laces subject vibration and large shocks.

• Places subject to splashing liquid or oil atmosphere.

• Places directly subject to heat radiated from heating equipment.

• Places subject to intense temperature changes.

• Places subject to flammable or explosive gas.

(5) To allow heat to escape, do not block the area around the product. (Ensure enough space for

heat to escape.)

(6) If you remove the controller from its case, never touch nor apply shock to the electronic parts

inside.

(7) Cleaning: Do not use paint thinner or the equivalent. Use standard grade alcohol to clean the prod-

uct. (8) Use specified size (M3.5, width 7.2mm or less) crimped terminals for wiring. (9) Allow as much space as possible between the controller and devices that generate a powerful

high-frequency (e.g. high-frequency welders, high-frequency sewing machines) or surge.

PRECAUTIONS FOR ENSURING CORRECT USE

F Use a 100 to 240 V AC (50/60 Hz), 24 VAC (50/60 Hz) or 24 VDC power supply matched to the

power specifications of the E5EK-DRT. Also, make sure that rated voltage is attained within two seconds of turning the power ON.

F Attach a surge suppress or or noise filter to periphe ra l devices that generate noise (in particular,

motors, transformers, solenoids, magnetic coils or other equipment that have an inductance component).

F When mounting a noise filter on the power supply, be sure to first check the filter’s voltage and

current capacity, and then mount the filter as close as possible to the controller.

F Insert a noise filter (TDK ZCB2206-11 or equivalent) on the AC power l ine to satisfy conducted

emission rating (FCC Regulation Class A EN50081-2-compliant).

F Use within the following temperature and humidity ranges:

• Temperature: -10 to 55°C, Humidity: 35 to 85% (with no icing or condensation) If the E5EK-DRT 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 subjecte d 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 to 65°C, Humidity: 35 to 85% (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.

F Setup mode

F Expansion mode

E5EK-DRT parameters are distributed between the following nine modes.

Protect mode Manual mode Level 0 mode Level 1 mode Level 2 mode Setup mode Expansion mode Option mode Calibration mode

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

This mode is used to limit use of the keys. The protect function is for preventing unwanted modification of parameters and switching between the auto and manual operation.

In this mode, the controller can be switched 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 may change the set point during operation, and stop and start operation. You can also monitor (not change) the process value, ramp SP and manipulated variable.

This is the main mode for adjusting control. In this mode, you can execute AT (auto-tuning), and set alarm values, the control period, PID parameters and heater burnout al arm (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, switch between the SP 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.

This is the mode for setting expanded functions. In this mode, you can set, SP setting limiter, selection of 2 -PID control or ON/OFF control, specification of the standby sequence resetting method, time for automatic return to the monitoring display.

CHAPTER 1 INTRODUCTION

1.5 About Calibration

The E5EK-DRT controller is calibrated before shipment from the factory. So, the user need not calibrate the E5EK-DRT controller during regular use.

However, if the E5EK-DRT controller must be calibrated by the user,

use the parameters provided for user to calibrate temperature input, analog input (voltage, current). 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

the E5EK-DRT controller is calibrated. Calibration data set before shipment from the factory cannot be returned to after calibration by the user.

F Calibrating

inputs

F Registering

calibration data

The input type selected in the parameter is the item to be calibrated. The E5EK-DRT is provided with the following four calibration parame-

ters.

• Thermocouple

• Platinum resistance thermometer

• Current input

• Voltage input

Two parameters are provided for thermocouple, platinum resistance thermometer and voltage input.

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 calibrating the E5EK-DRT controller. 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.

This chapter describes basic operation according to this flow. Examples of operation for each of these items are described at the end of the setting examples for the parameter in question. However, you must pro-

ceed to the first parameter of the subsequent item.

For example, to perform “setting output specifications” after complet-

ing “setting input specifications,” proceed to the first parameter of “setting output specifications” from the final parameter of “setting input specifications.” For details on moving parameters between items, follow

the procedures in “Selecting modes” and “Selecting parameters” described on pages 1-7 and 1-8.

3.1 Convention Used in this Chapter

F Setup

The following are examples of how to set up each of the items. These examples assume that the controller is operated at the factory defaults.

Themainspecificationsofthesetupexamplesinthischapterareasfol-

lows:

• A K thermocouple is connected to the controller.

• The control output (heat) function is assigned to control output 1,

and the alarm 2 function is assigned to auxiliary output 1. A relay output unit is also attached to control output 1.

• The upper limit alarm is set. In this example, alarm 2 is set. An alarm is output when the temperature exceeds 10_C of the set point.

The control example that is configured based upon the setup example is as follows:

JAnalog input

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

• 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”.

In other words, heating and cooling control is carried out when control output (cool) is assigned, and standard control is carried out when output is not assigned. For details on heating and cooling control, see 4.1 Selecting the Control Method (page 4-2).

• Factory settings are as follows:

control output 1 = Control output (heat) control output 2 = Alarm 1 auxiliary output 1 = Alarm 2 auxiliary output 2 = Alarm 3.

• Output assignments are set in the “control output 1 assignment”, “control output 2 assignment”, “aux output 1 assignment” and “aux output 2 assignment” parameters (setup mode).

CHAPTER 3 BASIC OPERATION

JDirect/reverse

operation

JControl period

• “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), is lower than the set point (SP), in a heating control system, the manipulated variable increases by the difference between the PV and SP values. Accordingly, this becomes “revers e operation” in a heating control system. Alternatively, this becomes “direct operation” in a cooling control system.

• Direct/reverse operation is set in the [ tion” parameter (setup mode).

• When the output unit is pulse output such as relay output, set the pulse output cycle (control period). Though a shorter pulse period provides better control performance, the control period should be set taking the life expectancy of the output unit into consideration when the output unit is relay. It is recommended that the control period be set to longer than 20 seconds.

• The control period is set in the “control period (heat)” parameter (level 1 mode). Factory setting is “20:20 seconds.”

• The “control period (cool)” output function is not allocated. So, the “control period (cool)” parameter cannot be set.

CHAPTER 3 BASIC OPERATION

3.4 Setting Alarm Type

• Three alarm outputs are supported: alarms 1 to 3. Of these, only the alarm assigned as the output can be used.

• Alarm output conditions are determined according to the combination of the “alarm type”, “alarm value” and “alarm hysteresis” parameter settings.

• The contact conditions when alarm output is ON can be set to “open” or “closed” in the “close in alarm/open in alarm” p arameter.

JAlarm type

• Alarm values are indicated by “X” in the table above. Alarm output operation differs according to whether the value of the alarm is positive or negative.

• Alarm values are set independently for each alarm in the “alarm value 1 to 3” parameters (level 1 mode). Factory setting is “0”.

Alarm hysteresis

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

0.02%FS”.

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

• For example, when the alarm type is set to “deviation lower limit,” generally the process value is within the alarm range, and al arm output become ON as it is as the process value when the power is turned ON is smaller than the set point. However, if the alarm type is set to “deviation lower limit with standby sequence”, alarm output first becomes ON when the process value exceeds the alarm setting value to leave the alarm range and on ce again falls below the alarm value.

• When an alarm is output, the standby sequence is canceled. For details on the standby sequence reset conditions, see “Chapter 5, Expansion Mode, Standby sequence reset method” on page 5-34.

JCloseinalarm/openinalarm

• When the controller is set to “close in alarm,” the status of the alarm output function is output as it is. When set to “open in alarm,” the status of the alarm output function is output inverted.

oseinalarm

peninalarm

• Alarm type and close in alarm (normally open)/open in alarm (normally close) can be set independently for each alarm.

• Close in alarm/open in alarm is set in the “alarm 1 to 3 open in alarm” parameters (setup mode). Factory setting is [ alarm”.

• When switching between manual and auto operation, the manipulated variable is subject to balance-less, bump-less operation.

• If the power is interrupted during manual operation, manual operation is resumed at the manipulated variable at power interruption when the power is reset.

• You can switch the AUTO/MANUAL function up to 100,000 times.

Balance-less, Bump-less Operation

To prevent sudden changes in the manipulated variable when switching between manual and auto operation, operation is resumed using the value that was active immediately before operation was switched, and the value is brought gradually closer to the value immediately after operation was switched.

About PID Parameters

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 5-12).

For details on how to assign outputs, see 3.3 Setting Output Specifications (page 3-7).

• When heating and cooling control is selected, the “deadband” and “cooling coefficient” parameters can be used.

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 positive value produces a dead band, while setting a negative value produces an overlap band. Default is set to “0.00: 0.00% FS.”

If the heating and cooling characteristics of the control target greatly differ, preventing satisfactory control characteristics from being obtained by the same PID parameters, adjust the proportional band (P at cooling side) using the cooling coefficient to balance control b etween the heating and cooling sides. In heating and cooling control, P at the heating or cooling side is calculated by the following formula:

Heating side P = P; Cooling side P = cooling coefficient ¢ P

• In heating and cooling control, the manipulated variable output that is output when controller operation is stopped is dependent on the set value of the “MV at stop” parameter (level 2 mode) in the same way as for standard control.

• However, note that in heating and cooling control, the manipulated variable at the cooling side is treated as a negative value for the sake of convenience. When the manipulated variable at STOP 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. The factory setting is “0”. If the controller is operated using the factory setting, the manipulated variable is not output to both the heating and cooling sides.

F MV limiter

The upper-and lower-limit values of the manipulated variable can be restrictedbytheMVlimiter,andthechangerateofthe manipulated variable can be restricted by the MV change rate limiter.

The upper-and lower-limit values of the manipulated variable are set in the “MV upper limit” and “MV lower limit” parameters (level 2 mode). When the mani pulated variab le calculated by the E5EK-DRT is outside of the range of the MV limiter, actual outputs are dependent on the set value of these parameters.

In heating and cooling control, the manipulated variable at the cooling side is treated as a negative value for the sake of convenience. The upper limit is set for the heating side (positive value), and the lower limit is set for the cooling side (negative value) as shown in the following figure.

The limiters are invalid or cannot be set when any of the following conditions occurs:

• During ON/OFF control

• During AT execution (only by MV change rate limiter)

• During manual operation

• When operation is stopped

• When an error has occurred.

The setting range of the set point is limited by the set point limiter. The upper-and lower-limit values of this set point limiter are set in the “Set

point upper limit” and “Set point lower limit” parameters (expansion mode), respectively. However, note that when the set point limiter is reset, the set point is forcibly changed to the upper-or lower-limit value of the set point limiter if the set point is out of the limiter range. Also,

when the input type, temperature unit and scaling (sensor) ran ge are changed, set point limiter is forcibly reset to the scaling (sensor) range.

4.3 How to Use the Remote SP

• Taking a remote SP input (4 to 20 mA) as the set point is referred to as the “remote SP” function. The remote SP function is enabled only when the “remote SP (RSP) enable” parameter (option mode) is set to “ON”.

JScaling

• Remote SP upper-and lower-limit values can be set by scaling.

• Inp uts within the range 4 to 20 mA (-10 to 110%) are allowed as

remote SP inputs. Inputs not within this range are regarded as out-ofrange input values. In this case, input is clamped at the remote SP lower or upper limit values, and the “RSP” LED blinks.

• If the output function “RSP input error” is assigned for when an outof-range remote SP is input, the “RSP input error” output is turned ON. Control output also switches to the setting of the “MV at PV error” parameter.

• Set the upper limit value in the “remote SP upper limit” parameter and the lower limit value in the “remote SP lower limit” p arameter (option mode).

the SP tracking function is enabled. If this function is disabled, the SP will be switched to “LSP1”.

• When the local SP is switched to the remote SP, the SP ramp will operate if the SP ramp function is enabled.

• During auto-tuning, remote SP input is not accepted. Auto-tuning is executed on the set point at the start of auto-tuning.

• Remote SP is not subject to the standby sequence reset conditions.

4.4 How to Use the Heater Burnout Alarm

• 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 (HB) alarm” to control output 1 or 2, auxiliary outputs 1 or 2.

JHeater burnout

To E5EK-DRT CT terminal

Heater wire

F HBA

JOperating

conditions

• 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 gen-

erates AC current proportional to the current value. The E5EKDRT measures this AC current to calculate the current flowing to the heater.

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

former 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 check 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 E5EK-DRT power supply ON. If the heater power supply is turned ON after turning the E5EK-DRT 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.) So, remedy the condition such as repairs which are caused by the heater burnout alarm.

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

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

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

2.5 A or more.

• Heater burnout alarm function cannot be used when controlling the heater by a phase control method or by a cycle control method. Also, 3-phaseheaterscannotbeused.

When detecting heater burnout on a 3-phase heater, use the K2CU-FVVA-VGS (with gate input terminal). (For details, see the respective data sheet.)

4--9

CHAPTER 4 APPLIED OPERATION

JHow 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)

• Setthecurrentvalueatburnoutwhentwoor moreheatersareconnected to the CT to the value at the time that the heater having the smallest 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 or more 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 setting range is 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 o r more, [

] is displayed in the “heater cur-

rent monitor” parameter.

4.5 LBA

• The LBA function can be used only when 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 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 L BA detection

F L BA detection

F L BA detection

example

• 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 p redicted 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 at maximum output.

LBA detection time

LBA detection width

Output

Time

Heater burnout

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

• At the 2nd judgment timing, the process value increases as indicated by the broken line of 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 timing and the LBA output b ecomes ON.

• Calculate the LBA detection time as follows:

(1) Set output to maximum.
