15 Safety recautions for Floatless Level lers!warning Do not touch the terminals while power is being supplied. Doing so may occasionally result in electric shock. Do not attempt to disassemble, repair, or modify the product while the power is being supplied. Doing so may occasionally result in electric shock. recautions for Safe se Do not use the ler in locations subject to explosive or combustible dust, combustible gas, flammable vapors, corrosive gas, excessive dust, salt water spray, or water drops. recautions for Correct se Operating Environment se and store the ler within the rated ambient operating temperature, ambient operating humidity, and storage temperature ranges specified for individual models. se the ler according to the characteristics specified for individual models for vibration, shock, exposure to water, and exposure to oil. Install the ler as far as possible from devices that generate strong high-frequency noise (such as high frequency welders or sewing machines). Tighten Terminal Screws to the Specified Torque When fitting crimping terminals to terminal screws, use a tightening torque of between 0. and 0. N m se a ower Supply with inimal Voltage Fluctuation Avoid connection to a power with a voltage fluctuation greater than or equal to +10% or 1%. Consider the Ambient Temperature Do not install the ler where it may be exposed to a temperature of C or higher or a humidity of % or higher. In particular, install the ler away from heat-generating equipment incorporating coils or windings. Do not use the ler outdoors or in locations subject to high humidity, corrosive gases, or direct sunlight. Avoid Vibration and Shocks Do not subject the ler to vibration or shocks which can cause chattering problems. Do not install the ler near contactors that generate severe shocks while the contactors are in operation. general-purpose applications and 0% of the specified length for long-distance applications. When selecting cable specifications, remember that the wiring length is further decreased for underground cables and larger diameter cables because of the increased floating capacity with the ground. Keep ower Cables Separate from the Electrode Circuit Do not pass the leads for the Electrode through the same duct, or near to, high-tension cables or power cables. This can cause noise which leads to malfunctions. Ground Correctly Ground the common Electrode terminal to reduce the effects of noise. se a Surge Suppressor Connect a 1F-03B(-0B) Surge Suppressor with the ler s Electrode terminals to protect the from surges. This is particularly important in lightning-prone areas. To further improve protection, install a commercial surge suppressor in the power to eliminate surges in the power system. (Refer to 1F-03B/-0B.) Consider the Response Times The ler requires a response time not exceeding 0 ms for operation or 10 ms for reset. Take these response times into account in cases where precise sequence control is required. Consider the Liquids to Be led The ler cannot be used for any liquid that has almost no conductivity such as sewage containing oil. The ler cannot be used for any flammable liquid such as gasoline, kerosene, or heavy oil. Do Not Share Electrodes Do not connect a single Electrode to more than one ler. If the phases of the -VAC Electrode- power supplies are opposite to each other, as shown in Fig. 1, an internal close (return ) is created (indicated by the arrows). The ler may malfunction regardless of the liquid level when the ler power is turned ON. This problem can be overcome by matching the power phases, as shown in Fig. 2, but in this configuration the internal impedance of the ler calculated from the Electrode will be approximately half as large as the internal impedance of a single ler. aintain sufficient clearance between Electrodes connected to separate lers so that they do not interfere with each other. Common leads, however, can be connected to the ground Electrode. Fig. 1 Internal Closed Circuit Do Not Test with a egaohmmeter During insulation resistance measurements, never apply the megaohmmeter across the Electrode terminals. X X se Self-holding Electrodes se Self-holding () Electrodes when contactor open/close control is carried out. If Electrodes are used, ripples on the liquid surface can cause incorrect contactor operation and damage to the contacts. Be sure to turn OFF the power before replacing the plug-in models. Short Wiring in Electrode Circuit Keep the wires connecting the ler to Electrode Holders as short as possible. If long leads are used, the floating capacity of the leads, and abnormal surges or noise in the Electrode can cause malfunctions. The thicker the cables, the shorter the permitted wiring length. The length of the cable connecting the ler and Electrode is specified in the ler datasheet as a guideline assuming that a 00-V VCT 0.-mm 2, 3-core cabtire cable is used. Test results indicate that the actual wiring length using VCT 3.-mm 2, 3-core cable laid over the ground is 0% of the specified length for Fig. 2 atch hases VAC T S R 1F S0 S2 1F S0 S2 VAC C-1
