Note: 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 de-
tails, refer to Safety Precautions for Floatless Level Controllers.
3. The length when using completely-insulated, 600-V, 3-conductor (0.75 mm
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 ter-
minals 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 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.

• 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.
