■ Safety Precautions

Do not touch the terminals while power is being supplied. Doing so may occasionally result in minor injury due to electric shock.

Use a power supply that complies with the reinforced insulation specified in IEC 60664 for the EJ1 external power supply or the power supply connected to the EJ1. If non-compliant power supplies are used, electric shock may occasionally result in minor injury.

Do not allow pieces of metal, wire clippings, or fine metallic shavings or filings from installation to enter the product. Doing so may occasionally result in electric shock, fire, or malfunction.

Do not use the product where subject to flammable or explosive gas. Otherwise, minor injury from explosion may occasionally occur.

Never disassemble, modify, or repair the product or touch any of the internal parts. Minor electric shock, fire, or malfunction may occasionally occur.

CAUTION

Tighten the terminal screws to between 0.40 and

0.56 N·m. Loose screws may occasionally result in fire.

Set the parameters of the product so that they are suitable for the system being controlled. If they are not suitable, unexpected operation may occasionally result in property damage or accidents.

A malfunction in the product may occasionally make control operations impossible or prevent alarm outputs, resulting in property damage. To maintain safety in the event of malfunction of the product, take appropriate safety measures, such as installing a monitoring device on a separate line.

Precautions for Safe Use

Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse affects on the performance and functions of the product. Not doing so may occasionally result in unexpected events.

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

• Places directly subject to heat radiated from heating equipment

• Places subject to splashing liquid or oil atmosphere

• Places subject to direct sunlight

• Places subject to dust or corrosive gas (in particular, sulfide gas or ammonia gas)

• Places subject to intense temperature change

• Places subject to icing or condensation

• Places subject to vibration or strong shocks

2) Use and store the product within the rated ambient temperature and humidity ranges. Mounting two or more Temperature Controllers side by side, or mounting Temperature Controllers above each other may cause heat to build up inside the Temperature Controllers, which will shorten their service life. If the Temperature Controllers are mounted above each other or side by side, use forced cooling by fans or other means of air ventilation to cool down the Temperature Controllers.

3) To allow heat to escape, do not block the area around the product. Do not block the ventilation holes on the product.

4) Be sure to wire properly with correct polarity of terminals.

5) Use specified size (M3, width 5.8 mm or less) crimped terminals for wiring. Use a gage of AWG22 to AWG14 (equal to cross-sectional area of 0.326 to 2.081 mm AWG28 to AWG16 (equal to cross-sectional area of 0.081 to 1.309 mm length is 6 to 8 mm.) Up to two wires of same size and type, or two crimped terminals can be inserted into a single terminal.

6) Do not wire terminals that do not have an identified use.

7) To reduce inductive noise, keep the wiring for the product's terminal block away from power cables carrying high voltages or large currents. Also, do not wire power lines together with or parallel to product wiring. Using shielded cables and using separate conduits or ducts is recommended. Attach a surge suppressor or noise filter to peripheral devices that generate noise (in particular, motors, transformers, solenoids, magnetic coils or other equipment that have an inductance component). When a noise filter is used at the power supply, first check the voltage or current, and attach the noise filter as close as possible to the product. Allow as much space as possible between the product and devices that generate powerful high frequencies (high-frequency welders, high-frequency sewing machines, etc.) or surge.

8) Use the product within the rated load and power supply.

9) Make sure that the rated voltage is attained within two seconds of turning ON the power using a switch or relay contact. If the voltage is applied gradually, the power may not be reset or output malfunctions may occur.

10) Make sure that the product has 30 minutes or more to warm up after turning ON the power before starting actual control operations to ensure the correct temperature display.

11) The switch or circuit breaker must be within easy reach of the operator, and must be marked as a disconnecting means for this unit.

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

13) Design the system (e.g., the control panel) allowing leeway for the delay required before product outputs are valid after turning ON power to the product.

14) Never touch the electronic components, connectors, or patterns on product boards with your bare hands. Always hold the product by the case. Inappropriately handling the product may occasionally damage internal components due to static electricity.

) for all other lines. (The stripping

15) Use a switch, relay, or other device with contacts to turn OFF the power supply quickly. Gradually lowering the voltage of the power supply may result in incorrect outputs or memory errors.

16) Do not touch the electronic components with your hands or subject them to shock when removing the terminal block.

17) Connect only the specified number of products in only a specified configuration.

18) Mount the product to a DIN Rail mounted vertically to the ground.

19) Always turn OFF the power supply before wiring the product, replacing the product, or changing the product configuration.

20) Attach the enclosed cover seal to the connector opening on the left end Unit during installation.

21) Do not use port B on the End Unit when using port C on the HFU.

Precautions for Correct Use

● Installation

1) Do not connect an End Unit directly to an HFU.

2) Always connect an End Unit to the right side of the Basic Units.

3) Always connect the HFU to the left side of the Basic Units.

4) The EJ1 cannot be used linked to a CJ-series PLC.

5) Use the EJ1G-@@ for gradient temperature control. Use the EJ1N-@@ for any other type of temperature control.

6) When removing the terminal block to replace the Unit, be sure to confirm that the new Unit is the same as the Unit that is being replaced.

● Service Life

1) Use the product within the following temperature and humidity ranges.

Temperature:

Humidity: 25% to 85% When the Temperature Controller is incorporated in a control panel, make sure that the controller’s ambient temperature and not the panel’s ambient temperature does not exceed 55

2) The service life of electronic devices like the Temperature Controller is determined by the service life of internal electronic components. Component service life is affected by the ambient temperature: the higher the temperature, the shorter the service life and the lower the temperature, the longer the service life. Therefore, the service life can be extended by lowering the temperature of the Temperature Controller.

3) Mounting two or more Temperature Controllers side by side, or mounting Temperature Controllers above each other may cause heat to build up inside the Temperature Controllers, which will shorten their service life. If the Temperature Controllers are mounted above each other or side by side, use forced cooling by fans or other means of air ventilation to cool down the Temperature Controllers. However, be sure not to cool only the terminals. Doing so will result in measurement errors.

−10 to 55°C (with no icing or condensation)

°C.

● Ensuring Measurement Accuracy

1) When extending or connecting the thermocouple lead wire, be sure to use compensating wires that match the thermocouple types.

2) When extending or connecting the lead wire of the platinum resistance thermometer, be sure to use wires that have low resistance and keep the resistance of the three lead wires the same.

3) Mount the Temperature Controller so that it is horizontally level.

4) If the measurement accuracy is low, check to see if input shift has been set correctly.

● Precautions for Operation

1) It takes a certain amount of time for the outputs to turn ON from after the power supply is turned ON. Due consideration must be given to this time when designing control panels, etc.

2) It takes 30 minutes from the time the product is turned ON until the correct temperature is indicated. Always turn ON the power supply at least 30 minutes before starting temperature control.

3) Avoid using the Temperature Controller near a radio, television set, or other wireless device. Its use would result in reception disturbance.

• If reinforced insulation is required, connect the input and output terminals to a device without any exposed current-carrying parts or to a device with standard insulation suitable for the maximum operating voltage of the power supply I/O section.

• Conforming to Safety Standards The power supply terminals must be supplied from a SELV, limited-current source. A SELV (separated extra-low voltage) source is a power supply having double or reinforced insulation between the primary and the secondary circuits and having an output voltage of 30 V r.m.s. max. and 42.4 V peak max. or 60 VDC max. Recommended power supply: S8VM Series or S8VS Series (both manufactured by OMRON)

Note Select a power supply that suits the operating environment.

• To comply with the standards for noise terminal voltage for class A in EN 61326, install a noise filter (Densei Lambda MXB-1206-33 or the equivalent) to the DC line as close as possible to the EJ1.

HFU can control up to 32 TC4/TC2 Units.

• The unit numbers of the TC4/TC2 Units can be set to between 0 and 31.

• To connect 16 or more TC4/TC2 Units, Communications Cables must be used to distribute Unit positioning because the maximum number of Units that can be connected horizontally will be exceeded.

• When using Communications Cables to distribute TC4/TC2 Unit positioning, connect the cables to port B on the End Units.

• If distributed positioning is used for an EJ1, power must be supplied separately to the terminal block on the End Units.

or turn ON power to the HFU and distributed Units simultaneously. Even if this is done, there may still be problems with the startup timing depending on the EJ1 configuration and power supply capacity. If problems occur at startup, increase the delay between turning ON the power to the distributed Units and the HFU.

One HFU can manage up to 32 TC Units (4 channels × 32 Units = 128 channels) EDU Units are not included in the number of Units that can be managed.

Turn ON pin 8 on SW2.

4-1-3 Analog Inputs

Conditions for use

The input type must be set to thermocouple or infrared temperature sensor.

When an analog input is selected, scaling can be performed as needed by the control application.

• The Scaling Upper Limit, Scaling Lower Limit, and Decimal Point Position parameters are used for scaling. These parameters cannot be used when a 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 Position parameter specifies the number of digits below the decimal point.

• The following example shows scaling of an analog input (4 to 20 mA). After scaling, the humidity can be read directly. In this case, the decimal point is set for 1 digit below the decimal point.

1,2,3... 1. Shift the controller readout at two reference temperatures, near room tem-

perature and near the value at which the temperature of the control target is to be controlled. Bring the temperature of the control target close to room temperature and close to the set point, and check control target temperature (B) and controller readout (A).

2. Check the temperature of the control target near room temperature (B) and the controller readout (A), and calculate the temperature difference as shown below.

Object temperature (B) − Controller readout (A)

Set the temperature difference as Input Shift 1 and set the controller readout (A) as Input Value 1 for Input Correction.

3. Check the temperature of the control target near set-point temperature (B) and the controller readout (A), and calculate the temperature difference as

shown below.

Object temperature (B) − Controller readout (A)

Set the temperature difference as Input Shift 2 and set the controller readout (A) as Input Value 2 for Input Correction.

4. After you have set the calculated values, check controller readout (A) and control target temperature (B).

5. In this case, the two-point shift was performed near room temperature and the set-point temperature, but if you want to improve accuracy near the set point, perform the two-point shift at points above and below the set-point temperature. An example shift is shown in the following diagram.

■ Two-point Shift Example

In this example, the input type is set to K (5): −200°C to 1,300°C. Check the temperature of the control target.

When room temperature (B) = 25°C, the Controller readout (A) = 40°C.

When the temperature near the set point (B) = 550°C, the Controller readout (A) = 500°C.

In this case, the input shift parameters are calculated as follows: Input Value 1 for Input Correction = Controller readout (A) = 40°C Input Shift 1 = Object temperature (B) - Controller readout (A) =

25°C

− 40°C = −15.00°C

control period.

OFF

Control period

Note Control responsiveness improves as the control period is short-

ened, but if relays are being used for heater control, the relay lifetime will also be shortened so we recommend using a control period of at least 20 seconds.

Variable type Parameter name Setting range Default

E1/A1 Control Period 1 to 4 (I/O) 0 to 99 s 2

Conditions for use Control output must be assigned and set to 2-PID control.

These parameters are not valid for outputs 1 and 2 on Controllers with linear outputs.

Note This parameter can be set only when operation is stopped. If the parameter is

set to 0, the period will be 0.5 s.

4-2-3 Minimum output ON/OFF width

Set the minimum output ON/OFF width. When using output relays, this function can be used to prevent the relay from

deteriorating. The relationship between MV and actual output is shown in the following diagram.

These parameters are not valid for outputs 1 and 2 on Controllers with linear outputs.

0.0 to 50.0% 1.0

Note (1) This parameter can be set only when operation is stopped.

(2) When the control cycle is short due to the 2-ms output resolution, the Unit

may not operate as set. For example, when the Control Cycle = 1 s and the Output Minimum ON/OFF Duration = 0.1%, the calculation becomes 1 s (1,000 ms) x 0.1% = 1 ms, but the actual output minimum ON/OFF duration is 2 ms.

!Caution If the Output Minimum ON/OFF Duration is too large, control performance

may suffer.

4-2-4 Output ON Scheduling Function

The ON time for each output can be reduced to one half or one fourth of the control period to limit the number of outputs in the Unit that are ON simultaneously.

0 to 1000 ms (See note 2.)

Note (1) When this parameter has been changed, the new setting becomes effec-

tive the next time a software reset is performed for the Unit or the next time power is turned ON.

(2) Set the Delay between Outputs parameter to an even number. If an odd

number is set, the next smaller even number will be used.

!Caution

• Set the Output Mode Selection parameters to Standard Control for all of the

Unit's channels. The Output ON Scheduling function will be disabled if the parameter is not set to Standard Control.

Setting Output Specifications Section 4-2

• Even if the Output ON Scheduling Method is set, the outputs may be ON at

the same time due to the delay in the output device's operation. In this case, you can prevent the outputs from being ON simultaneously by setting a delay with the Delay between Outputs parameter. Refer to the following setting examples for details on using the delay.

• When using both this function and autotuning, always set this function

before performing autotuning. If this function is set after autotuning, control performance may deteriorate.

• When using this function, set the following parameters to their default set-

tings: Output Scaling Upper Limit 1 to 4, Output Scaling Lower Limit 1 to 4, and Decimal Point C1 to C4. If these parameters are not set to their defaults, the Output ON Scheduling function will not operate properly.

• This function will also be applied to manual outputs, outputs during errors,

and outputs while stopped, so these outputs may be lower than their set values.

• When using the Output ON Scheduling function, all of the Unit's outputs will

operate with the OUT1 control period.

• ST will be disabled when using the Output ON Scheduling Method.

4-3-2 Selecting the Control Method

The control method can be set to either 2-PID control or ON/OFF control.

Variable type Parameter name Setting range Default

E5/A5 PID/OnOff (Channel) 0: 2-PID control

1: ON/OFF control

Conditions for use No special conditions

Note This parameter can be set only when operation is stopped.

ON/OFF Control In ON/OFF control, the control output turns OFF when the currently controlled

temperature reaches a preset set point. When the manipulated variable turns OFF, the temperature begins to fall and the control output is turned ON again. This operation is repeated at a certain level. The Hysteresis (Heating) parameter determines how much the temperature must fall before the control output is turned ON again. Also, the Direct/Reverse Operation parameter determines whether the manipulated variable is increased or decreased in response to an increase or decrease in the process value.

■ Hysteresis

ON/OFF control incorporates a hysteresis setting to stabilize operation when switching ON and OFF. The width of the hysteresis loop determines the sensitivity.

• The control output (heating) and control output (cooling) hysteresis settings are made with the Hysteresis (Heating) and Hysteresis (Cooling) parameters, respectively.

• The sensitivity of standard control (heating or cooling) is set with the Hysteresis (Heating) parameter, regardless of the setting of the Direct/ Reverse Operation parameter.

• The Hysteresis (Cooling) parameter is effective only when using heating/ cooling control.

• Proportional action: In proportional action, the MV is proportional to the deviation (control error).

• Integral action: This control action produces an output that is proportional to the time integral of the control error. An offset normally occurs in proportional control, so proportional action is used in combination with integral action. As time passes, this offset disappears and the control temperature (process value) matches the set point.

Setting Control Specifications Section 4-3

• Derivative action: This control action produces an output that is proportional to the rate of change of the input. Since proportional control and integral control correct for errors in the control result, the control system will be slow to respond to sudden changes in temperature. The derivative action performs a corrective action by increasing the MV in proportion to the slope of the temperature change.

■ Direct Operation (Cooling) and Reverse Operation (Heating)

Direct operation (cooling) refers to control where the manipulated variable is increased in response to an increase in the process value. Alternatively, reverse operation (heating) refers to control where the manipulated variable is decreased in response to an increase 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 according to the difference between the PV and SP. Accordingly, this is “reverse operation” in a heating control system and “direct operation” in a cooling control system, which performs the opposite operation.

Variable type Parameter name Setting range Default

Conditions for use No special conditions

Setting Control Specifications Section 4-3

Heating/Cooling Control

To perform heating/cooling control, assign the control output (cooling) function to one of the outputs. For example, when you want to perform heating/cooling control with channel 1, assign channel 1 control output (cooling) to one of the outputs.

• Refer to 4-2-1 Control Output Assignments for details on assigning the

control output for cooling.

• The Cooling Coefficient and Dead Band parameters must be set for this

PID control, in addition to the Proportional Band (P), Integral Time (I), and Derivative Time (D) parameters.

■ Cooling Coefficient

If the heating characteristics and cooling characteristics of the control object are very different and good control characteristics cannot be achieved with the same PID constants, the cooling coefficient can be used to adjust the proportional band (P) for the control output assigned to cooling. Use this to achieve balanced control between the heating side and cooling side.

The proportional bands (P) for the control outputs assigned to the heating/ cooling sides can be calculated using the following equations.

• P for the heating side = P

• P for the cooling side = P for the heating side

× Cooling coefficient

The cooling P is obtained by multiplying the heating P by the cooling coefficient, so the cooling output control characteristics are different from the heating output control characteristics.

■ Set Point Limiter

These parameters apply a limit to the set point's setting range so that the control subject does not reach an abnormal temperature.

Conditions for use No special conditions

Note The decimal point position is determined by the sensor selection.

Set the SP Upper and Lower Limits within the input range and also set the SP Upper Limit > SP Lower Limit. If the SP Lower Limit > SP Upper Limit, the larger value will function as the SP Upper Limit. In addition, if the limit range is set outside of the input range, it will be limited to the input range. The SP will not be changed automatically, even if the input type or SP Limiter is changed. Although the SP will not be changed automatically, the internal SP used for control will be limited to the input range or SP Limiter (whichever range is narrower).

4-3-5 Setting the SP Ramp

The SP ramp function restricts the width of changes in the set point as a rate of change. When the SP ramp function is enabled and the change width exceeds the specified rate of change, this function can restrict the set point within an area, as shown in the following diagram.

While the SP ramp function is operating, control will be performed not for the specified set point but rather for the set point restricted by the rate of change set for the SP ramp function.
