Feed pump is not properly balanced for the required fill rate resulting in rapid cycling of the switches. Check the Float. Let's start with the most basic float switch: a two-wire, single-pole, single-throw float switch.

Make sure you turn off the power to the high voltage and low voltage wires from the pump. The patented magnetic reed switch allows it to be installed off-center and still function correctly. I can not seem to locate the part number for the relay switch. In order for the switch to open it must be positioned in a location that is dry normally and will reliably fill with water when a drainage issue occurs.

Connect the black lead to the other terminal on the switch. Float level switch with Z-type arm to work around existing arrangement. In this article we will discuss in further detail how to choose the correct float for your application. The meter should display 1 ohm or less, meaning the switch is 'ON. Please note: Most float switches have a white and black wire, which means you will most likely have a white to black connection.

Shitty drainwork and a lack of redundant overflow protection like a secondary pan is just bad install. In order for the switch to open it must be positioned in a location that is dry normally and will reliably fill with water when a drainage issue occurs.

Selecting the mode is as easy as removing the retaining clip and reversing the float on the stem.

If you want to fill a tankthen you will need a normally-closed switch to start a pump motor when the liquid level is low and to stop the pump once the tank is full.

This is perfectly normal and the correct way to do it.Submersible pumps use float switches to perform automatic operation. The float switch moves with the water level in the tank and this determines when the pump turns on and shuts off. In this article we will discuss the correct way to hard wire a float switch to a submersible pump in order to achieve automatic operation.

Please note: The information below refers to V pumps and wiring. We recommend using a piggy-back float switch or control panel to operate V pumps. In V wiring you are dealing with 3 legs: Hot, Neutral, and Ground. The pump will have these three wires and the incoming power supply will have these three wires.

The neutral wire from the panel will connect directly to the neutral wire from the pump. The ground wire from the panel will connect directly to the ground wire from the pump. Now you are left with the hot wire from the panel and the hot wire from the pump. The float switch has two legs. One leg of the float switch will connect to the hot wire from the panel; the other leg will connect to the hot wire from the pump.

Please note: Most float switches have a white and black wire, which means you will most likely have a white to black connection. This is perfectly normal and the correct way to do it.

Once these connections are made, you are ready to turn the power back on and the submersible pump should operate according to the position of the float switch.
