Precautionary Information !Caution Do not touch the terminals while power is being supplied. Doing so may possibly result in electric shock. Precautions for Safe Use * Do not disassemble, repair, or modify the product. * When attaching the product to the DIN rail, attach it firmly with screws. * When attaching the product to the DIN rail, ensure that the product has been attached firmly. * If the thickness of a mounting panel is not adequate, or a mistake has been made during installation, the product may become disconnected. * Ensure that terminal screws have been tightened firmly. Recommended torque: 0.49 N*m Assured torque: 0.59 N*m * When using the product, ensure that the wiring is correct before turning on the power. * Use a power-supply voltage that is within the range of specifications. * Use the control source and power supply or power lines that provide inputs with appropriate specifications. * Do not install near heat-generating devices (coils, or devices that use coils). * Be sure to confirm terminal numbers for correct wiring. * Ensure that wiring is correct. Double-check materials such as connection charts and circuit diagrams. * Properly ground the grounding terminal. Ensure that the common electrode terminal has been properly grounded. Doing so can alleviate effects from noise. * If electrodes make contact with liquid, purchase and use a separator to prevent such contact. * Keep appropriate distance from devices that generate highfrequency noise (e.g., high-frequency welders, electronic sewing machines). * Do not turn a setting volume beyond the scope of movement. * Do not connect anything to unused terminals. * Use SELV power supply with over load protection function for DC power supply. The insulation of SELV power supply must be a double or reinforced between input and output. The output voltage shall be 30 Vr.m.s. and 42.4 V at peak, or use the power supply of 60 V DC max. Recommended power supply: type S8VS-06024@ (OMRON made) Do not keep, install, or use this product in the following environments. * Outdoors, or places subject to direct sunlight or wearing weather. * Places where temperature and humidity exceed the allowable range of the product specifications. * Places where there are extreme changes in temperature and humidity, or icing or condensation may occur. * Places subject to static electricity or inductive noise. * Places subject to electrical fields. * Places where vibrations or physical shocks are strong. * Places where flammable gasses or flammable liquids exist. * Places where corrosive gases (in particular, sulfuric or ammonia gas) exist. * Places with large amounts of dust or iron powders. * Places where water or oil come in contact with the product. * Places subject to salt-water splashes. Precautions for Correct Use For Proper Use 1. Make sure to use setting values appropriate for the controlled object. Failure to do so can cause unintended operation, and may result in accident or corruption of the product. 2. When discarding, properly dispose of the product as industrial waste. 3. Only use this product within a board whose structure allows no possibility for fire to escape. 4. To avoid damage to the exterior of the product, do not use organic solvents (thinner, benzene) or agents with strong alkalinity or acidity. About Installation 1. When wiring, use only recommended crimp terminals. 2. Do not block areas around the product for proper dissipation of heat. (If you do not secure space for heat dissipation, life cycle of the product will be compromised.) Noise Countermeasures 1. Do not install the product near devices generating strong high frequency waves or surges. 2. When using a noise filter, check the voltage and current and install it as close to the product as possible. 3. In order to prevent inductive noise, wire the lines connected to the product separately from power lines carrying high voltages or currents. Do not wire in parallel with or on the same cable as power lines. Other measures for reducing noise include running lines along separate ducts and using shield lines. To avoid faulty operations, malfunctions, or failure, observe the following operating instructions. 1. During insulation resistance measurements, never apply the megohmmeter across the electrode terminals. 2. Use a power supply that will reach rated voltage within 1 second. 6 Conductive Level Controller 61F-D21T-V1 Cat. No. N149-E1-03A Cat.
