■ 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.
