If reinforced insulation is required, connect the input and output terminals to devices without any exposed current-carrying parts or to devices with reinforced insulation suitable for the maximum operating voltage of the power supply and I/O sections. • To comply with the standards for noise terminal voltage for class A in EN 61326, install a noise filter (Densei Lamda MXB-1206-33 or the equivalent) to the DC power line as close as possible to the Temperature Controller. • Use an SELV power supply that provides overcurrent protection. An SELV circuit is one separated from the power supply with double insulation or reinforced insulation, that does exceed an output voltage of 30 V r.m.s. and 42.4 V peak or 60 VDC max. The OMROM S8VS Series is recommended for the power supply.

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. Tighten the terminal screws to between 0.40 and 0.56 N·m. Loose screws may occasionally result in fire. For the EJ1C-EDUC-NFLK (model with connector terminal block), tighten the terminal block screws to between 0.50 and 0.60 N·m. 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 Observe the following points to ensure safe operation. 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 temperature and humidity ranges. Provide forced-cooling if required. 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. To connect bare wires to the terminal block, use copper braided or solid wires with a gage of AWG22 to AWG14 (equal to cross-sectional area of 0.326 to 2.081 mm2) for power supply lines and a gage of AWG28 to AWG16 (equal to cross-sectional area of 0.081 to 1.309 mm2). (The stripping length is 6 to 8 mm.) 6. Do not wire terminals that do not have an identified use. 7. Allow as much space as possible between the product and devices that generate a powerful high-frequency or surge. 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. 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. 10.It takes 30 minutes from the time the Temperature Controller is turned ON until the current temperature is displayed. Always turns ON the power supply at least 30 minutes before starting temperature control. 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. 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 product during installation. 21.Do not use port B on the end product when using port C on HFUs. 22.Install the product only after reading the manual provided with the End Unit. 20 EJ1 Precautions for Correct Use Installation Installation 1. 2. 3. 4. 5. Connecting Units 1. Align the connectors and connect the Units to each other. Connect an End Unit to the Unit on the right end. Do not connect the End Unit directly to an HFU. Connect the End Unit to the right side of a Basic Unit. Connect the HFU to the left side of the Basic Units. The Temperature Controller cannot be used as a CJ-series Unit. Use the EJ1G-@@ for gradient temperature control. When not using gradient temperature control, use the EJ1N-@@. 6. When removing the terminal block to replace a Unit, be sure 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: −10°C to 55°C (with no condensation or icing) 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°C. 2. The service life of electronic devices like Temperature Controllers is determined not only by the number of times the relay is switched but also 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. Note: 1. Do not connect the End Unit directly to an HFU. 2. Connect the End Unit to the right side of a Basic Unit. 2. Slide the yellow sliders on the top and bottom of the Units until they click into place. Lock Slider 3. Attach the cover seal to the connector opening on the Unit on the left end of the EJ1. 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. Cover Seal Removing the Terminal Block 1. Press down the terminal block lever. Precautions for Operation 1. A certain amount of time is required for the outputs to turn ON from the time the power supply is turned ON. Due consideration must be given to this time when incorporating Temperature Controllers in a sequence circuit. 2. It takes 30 minutes from the time the Temperature Controller is turned ON until the current temperature is displayed. Always turns 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. Lower the lever. 2. Pull out the terminal block. Pull out.
