Note: 1.
The relay in the 61F-G1H/-G2H/-IPH de-energizes when there is water present across the Electrodes, whereas the relay in the 61F-GP-
N8HY energizes when there is water present across the Electrodes.
2.
Models are available for 2 km and 4 km.
3.
The length when using completely-insulated, 600-V, 3-conductor (0.75 mm
2
) 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. For details, refer to
Safety Precautions for
Floatless Level Controllers.
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.

•
Insert a pushbutton switch between terminals 11 and 15 as
shown by the dotted lines.
•
Do not press the pushbutton if the low-water alarm sounds and
the pump stops during normal operation (water below E
2
').
Test Operation/Recovering from Power Interruptions
If the supply water level is below E
