The length when using completely insulated, 600-V, 3-conductor (0.75 mm ) cabtire cables. Usable cable lengths will become shorter as the cable diameter or number of conductors becomes larger. For details, refer to Safety Precautions for Floatless Level Controllers. 2. The insulation resistance and dielectric strength indicate values between power terminals and Electrode terminals, between power terminals and contact terminals, and between Electrode terminals and contact terminals. For details, refer to Safety Precautions for Floatless Level Controllers. 3. Possible to use with 15 k or less, however, this may cause reset failure. 4. 61F-GP-NH High-sensitivity Controller uses advanced operation. When the power supply voltage is applied, if there are some liquids between the electrodes (ground and operation electrodes), the inter- nal relay will not operate. When the power supply voltage is applied, if there are no liquids between the electrodes (ground and operation electrodes), the internal relay will operate. If the advanced operation does not satisfy applications, consider using 61F-N8HY controller which uses sequential operation. 2
