61F-GPN-V50AC240

Water Leak Detector 61F-GPN-V50 CSM_61F-GPN-V50_DS_E_5_5 Flexible Setup according to Water Quality and Surrounding Wiring Conditions • The operating resistance has a variable sensitivity from 0 to 50 kΩ, so the best set values can be made according to the predicted water leakage, degree of overflow, water quality, or surrounding wiring conditions. • The power supplied to the Sensing Band is 24 VAC, so operation is stable because there is no electrode deterioration from electrical corrosion. • A contact signal output enables monitoring from remote locations. [Reference] For detecting leakage of water with high resistivity, use K7L-U/-UD ultra high-sensitivity models. Refer to Safety Precautions for Floatless Level Controllers. Ordering Information Water Leak Detector When ordering, to complete the part number, be sure to specify the desired operating voltage. 61F-GPN-V50 Example: 61F-GPN-V50 [120/240 VAC] Desired supply voltage Specifications ■ Ratings/Characteristics Item Water Leak Detector Model 61F-GPN-V50 Supply voltage 24, 110, 120, 220, 230, 240 VAC Operating voltage range 85% to 110% of rated voltage Interelectrode voltage 24 VAC Operating current 3 mA (AC) max.

This current is amplified to operate a relay. In practice, leakage will be detected if water drops are present between the core wire and the Electrode (F03-15 Sensing Band) or detecting section (F03-16PE Sensing Band).

Doing so may possibly result in electric shock. Make sure that the terminal cover is installed before using the product. !CAUTION Do not attempt to disassemble, repair, or modify the product. Doing so may occasionally result in minor or moderate injury due to electric shock. ■ Precautions for Safe Use (1) Use only F03-15 or F03-16 Sensing Band. Other water conductors may cause the Water Leak Alarm/Detector to malfunction, or not operate at all because of mismatched sensitivity. (2) Place the Sensing Band at a location where water leakage is most likely to occur. For example, consider the following locations: • • • • Under a raised floor; on the highest floor of a building; on the ceiling In the vicinity of an air conditioner, or on the floor near a humidifier On the floor near a feed-water pipe, conduit; hot-water pipe. On top of a power, or control panel (3) Secure the Sensing Band so that they touch the floor surface or the wall near a pipe arrangement. Cover the Sensing Band with a F03-25 or F03-26 Protective Cover if they are installed at a location crowed with people. However, place the cover such a manner that water can easily reach the Sensing Band. (4) Keep the temperature at the installation site to within 55°C. Do not install the Water Leak Alarm/Detector/Sensing Band in the proximity of heat-generating equipment (such as that having a coil or wire winding). Also, do not use it in a highly humid location, or at a location that is subjected to corrosive gases. Do not place the Water Leak Alarm/Detector side-by-side with a highcapacity contactor that produces an inrush current when it operates, as such arrangement may cause chattering to occur, consequently causing a malfunction of the Water Leak Alarm/ Detector. (5) Wiring distance of the Sensing Band varies depending on the water quality. When using IV cables, wire the Sensing Band to the length specified in the following table. (6) Mount the 61F-WLA Water Leak Alarm/Detector on a sturdy wall surface which is not subjected to vibration or shock. Do not use double-sided adhesive tape, otherwise, the Detector may detach when the adhesive tape deteriorates due to aging. (7) When wiring the Sensor on conductive objects like metal objects, use the F03-16. (8) When measuring insulation resistance, do not conduct a megger test between the electrode terminals.
