Waterl pump protect circuit

My idea is to design circuit to automatic shut down pump when pump loses vacuum.. So far I have contactor either with 24 coil or 110v coil in series with vacuum switch.My problem is circuit will not close upon time clock starting pump because vacuum switch has no vacuum.If I could temporary short vacuum switch with time delay it would than be able to shut pump down if it lost vacuum for some reason. Any ideas

A momentary contact switch can be used to bypass the vacuum switch until operating pressures and vacuums are reached. It is called a start switch.

You need to install a time delay relay.

Pumps water for a minute then shuts off.

Probably the pump has a water pressure protection switch. So it will not run dry and burn up. How is it that you are losing water pressure? On the delivery end or receiving. Restrictions on a pump always are placed output

I installed a new Polaris winch on my 570 and it powers out but not in any ideas?

Jeff, The winch direction is controlled by the contactor and (polarity/relay) is switched using the switch/controller on the handle bars. I think you are dealing with one of a few possible situations. Lets narrow them down. 1) The winch motor. Bad in one direction only? this is highly unlikely. The body of the winch is electrically grounded properly or it would not run in the out direction..You may be able to manually reverse polarity to test the motor. If you do not understand this concept, then don't attempt anything that could make a short. 2) The contactor is a relay that has very delicate copper studs. If you over torqued them during the install, they easily break off. The contactor is the most likely issue. Double check the studs and ensure the wiring pattern is correct to and from the contactor. Ensure the wires/nuts washers are not touching the other leg of the contactor/studs - i.e. anything that could make a short. 3) The handle bar switch may be defective or wired wrong. Isolate the switch and make sure it works properly with a volt meter/continuity test.

I have personally experienced broken contactor studs, defective contactors and damaged handlebar switches. It took time to properly isolate and repair the issue.

After thoroughly cleaning, including removing impellor, water flow all but stops after several hours and then the pump shuts down completely.

It almost sounds as if the thermal load protection fault is being tripped on the pump. When the pump kicks off is the housing extremely warm? If so you may need to replace the pump.

I have an 12 x 24 pool. The intake valve is designed to stop taking in water when there is an obstruction in it. So I'm wondering if that is why the suction stops whenever I try to attach the vaccum hose...

Be sure to fully submerge the vacuum to remove all the air from the vacuum an hose. It could be that air in the hose is causing the pump to shut off.

My Ec 50 is brand new and when using the skimmer everything works just fine , but when I hook up the vacuum hose the filter will run for about a minute at 10 lbs pressure then drop to nothing (0). My...

You have air infiltrating the vacuum line somewhere. The hose may have a swivel cuff on one end that must be in the water, not attached to the skimmer. Next, check the gasket on to p of the pump housing. Under vacuum, the gasket may bleed air into the system shutting down the pump flow. Lastly, check the skimmer thoroughly for small cracks. Again, under vacuum it may open and allow air to infiltrate. The only way for a filter to go from 10-0 pressure is if the pump loses prime ie: air infiltration. Hope that helps.. Rob

Shuts off intermittantly, impeller moves freely

Does it come back on after resting/cooling down. If does peobably kick out on heat overload and is resetting itself. If impeller is free spinning with NO roughness or side play in bearing probably too much head pressure,pumping too far or too small pipe wich will cause excessive pressure making pump work to hard

There is power to the pump, but the pump will not come on. It has a pressure switch, the contacts are making contact, but the motor doesn't run. what should i check for?

Sometimes around the area of the motor there is a little button that is usually red that is made to "trip" if the pump got hot or overloaded. Push this button back in to reset if it has on. Most pumps have this button to keep them from burning up if overloaded.

Pump is over heating

There are a few possibilities. Pump duty cycle, ie. how long it is designed to run at one time. Most electric motors have a code on them or say continuous or some other duty cycle range. Is your pump designed to run as long as you run it. Next is wiring, are you using the correct gauge wire for the load? A wire size too large will generally not hurt, but decrease the wire size and your wire will heat up along with the motor. Usually this can cause the breaker to pop or the motor to over heat and stop. Another wiring issue could be a short or bad connection on either end. Some 230 motor will run on one leg of voltage but less efficient. Check the connections at both ends and put a meter on them to check for shorted wires and voltage on the wires at the pump. The last thing I can think or is that you have a defective pump in some way. Perhaps a bad bearing or seal. I am not familiar with pump controls yet. I am getting one soon. I am guessing there is a start/run capacitor in it. If it starts the pump it shouldn't be the source of your problem. Assuming all equipment you have is designed to work together. Good Luck.

Pump goes on and off

Does the pump have thermall protection? It sounds like its getting hot and tripping the thermal protection switch in the pump windings.
