*1. The [] in the model name represents G, G1, G2, G3, G4, and I.
*2. The suffix “TDL” attached to the model name represents models designed for tropical regions (storage humidity of
45% to 90%). For details, refer to Safety Precautions for Floatless Level Controllers.
*3. The length when using completely-insulated, 600-V, 3-conductor (0.75 mm2) 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.
*4. 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.
*5. Possible to use with 15 kΩ or less, however, this may cause reset failure.
*6. High-sensitivity Controllers use advanced operation.
When the power supply voltage is applied, if there are some liquids between the electrodes (ground and operation
electrodes), the internal 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.

Advanced Operation

With advanced operation, the internal relay operates as soon as control power is supplied to the G1F and is reset when current flows between the poles. Wiring is the same as for models with sequential operation.
