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.
Installation Instructions for the "RH" BW Control
Down Load Instructions Here
The 1500D sensor control will control your pump to keep a cistern full of water. It does so by turning the pump on when the water level drops in the cistern, and turns the pump off when the cistern is full.
Proper wiring of this unit is important to allow it to perform properly. The unit is wired between your power source and your pump control box.
The wire from your power source will have 2 wires that are hot with electricity. These will be referred to as L-1 and L-2.
L-1 will connect to the BW terminal #3
L-2 will connect to the BW terminal #4
From the BW #3, install a jumper wire to BW #5
From the BW #4, go into the pump control box to L-2 input
From the BW #6, go into the pump control box to L-1 input
Now it is time to set up your stainless steel electrodes for in the cistern.
There are 3 electrodes used in the proper installation. It is recommended that you leave the wire above each electrode hanging free in the cistern, at least 6" to 12" to prevent deposits from forming on the electrode that could cause false readings to the sensor control. It is also recommended that you place a bit of silicone gel on the top of the electrode cover where the wire goes in, to prevent water from getting into the top of the cap and being held there when the water drains from the bottom of the electrode. This will prevent false readings caused by water in the cap.
BW sensor #7 is jumper wired to BW sensor #9.
BW sensor #9 then goes to the upper level electrode in the cistern. This electrode is the one which turns the pump off when the cistern is full.
BW sensor #8 goes to your low level electrode. When the water level in the cistern drops to this level, the control signals the pump to turn on.
BW sensor #10 goes to a liquid ground. This should be hung in the cistern somewhere below the lower level pump turn on electrode. NOTE connecting this terminal to a ground stake will not provide a proper ground, and may make the control malfunction. Ground must be to liquid.
Need an alarm package to alert you when the cistern is low? We offer the #1005835 Tank Alert XT low water alarm package which can be used indoor or out.
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. $ 185.00
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.
