BW Electrode systems are one of the best ways to protect your water well submersible pump from running dry and being damaged. B/W relays are placed between your pump power supply and the controls for your submersible pump. From the BW relay, 3 electrode wires are run to the well and down to the electrodes hanging in the well. The lowest electrode is your liquid ground electrode, which goes below the pump, makes certain that proper ground is provided to the other two electrodes. One BW electrode is installed just above the submersible pump as the cutoff electrode. This electrode turns off the power before your pump starts to run dry. The Upper electrode is placed at a level below your static water line, and up from the cutoff electrode far enough to allow recovery time before the pump restarts. Once the water rises to a level where it covers the upper electrode, the B/W relay resets and allows power to go to the pump controls.
B/W PUMP UP CONTROLS
RH 115V HIGH WATER SHUT-OFF CONTROL is for use with 115V motors in a pump up to fill tank control mode. The
1500-D-L1 S7 OC X relay will turn off the pump when the tank or cistern has been filled.
RH 230V HIGH WATER SHUT-OFF CONTROL is for use with 115V motors in a pump up to fill tank control mode. The
1500-D-L2 S7 OC X relay will turn off the pump when the tank or cistern has been filled
E1S Stainless Steel Electrode
B/W PUMP DOWN CONTROLS
LH 115V LOW WATER CUT-OFF CONTROL
is for use with 115V motors in a pump down or low water level control mode. The
1500-C-L1-S7-OC-X relay will turn off the pump when a low water level in the well has been reached or when the tank or cistern being used as your water source has been emptied
LH 230V LOW WATER CUT-OFF CONTROL
is for use with 230V motors in a pump down or low water level control mode. Order the
1500-C-L2-S7-OC-X relay. $ 279.50
The BW control uses 3 electrodes to control your pump in the well. The first electrode is the ground to liquid electrode. It will be hung in the cistern below the other 2 electrodes. This assures a proper grounding of the sensor control and proper performance. A ground to a ground stake is not adequate to make your system work right.
The next electrode is above the ground electrode and provides the power on signal when the water level drops below it. This turns your pump on to refill the cistern.
The upper electrode is set at a level of full and turns the pump off when the cistern is full.
