The Environmental Electronic Level Switch is the latest innovation, as it operates with an electronic sensor, instead of the air pressure or any moving parts. It has been designed to sense the water level with great precision and accuracy, thus offering you the best possible result. One of the most important advantages of the E.E.L.S is that it is environmentally friendly. Nuova Rade designed this switch to operate only when it senses water. If there are quantities of hydrocarbons, such as oil, it switches the bilge pump off, thus preventing any pollution. Vertically mounted to the hull, the E.E.L.S is connected in line with bilge pump(s) even of higher potency. Also its compact design allows a far greater freedom of movement. Other features are the insulated electrical contacts, casing from durable Nylon and ABS, 100% impermeability to water.

Technical characteristics:

The Electronic Level Switch can be used with any bilge pump up to 22A. The Electronic Level

Switch has the following electrical characteristics:

Voltage: 12V DC

Connection to the main circuit: Inline Maximum Intensity: 22A.

How to connect the Electronic Level Switch

Connect a switch for the activation of the automatic operation of the bilge pump inline to the positive pole of the battery. You should also connect a fuse inline, according to the intensity of the bilge pump and up to 22A max (See manufacturer’s instructions). The wires of the Electronic Level Switch which are connected to the poles of the battery are RED (+) and BLACK (-). The other pair of wires, the BLACK (-) and BLUE (+), are connected to the negative and positive pole of the bilge pump respectively.

ATTENTION!

It is necessary that you follow the polarity when making the connections, otherwise you run the risk of producing a short circuit, leading to damage your Electronic Level Switch circuit. Please check the polarity before activating your new Float Switch.
