Before we can help you, can you let us know what brand, model, and type of device you need this help for. It was categorized as a vacuum cleaner but unfortunately this is not specific enough and the categories are often incorrect here as well.

Let me know and I'll answer if I can or pass it on and somebody who know more can answer for you.

    Here you go:

    The reset button is physically connected to the relay.

    If you are replacing the relay, the part will normally come with a diagram as well. The exact location of connectors can vary a bit .

    Yes, it;s pretty easy. The power cord coming in will have three wires. Green should be connected to the frame of the unit, and white will connect to a bunch of other white wires in some manner - probably a terminal block of some sort. Black will connect to the black lead on the transformer adn to any of four contacts in line with the contactors of the relay. These posts will be noticeably more heavy than the ones that drive the solenoid coil.

    The terminal(s) directly across from the black connection from the power cord should be connected to the motors - these wires should be blue, if not then they could be black.

    The DC side of the transformer will have a yellow and a blue wire most likely but the colors really don't matter. Connect one directly to one of the coil connections on the relay and the other to either end of the low voltage loop going to the inlets. Connect the other end of the low voltage loop to the other side of the relay coil

    Hope this helps.

Eureka boss central vac

Sounds like a problem with a relay switch in the unit. It could be a bad relay switch, or a bad transformer that powers the relay. It delivers power to the switch. If all that is good the next culprit might be a broken wire in the hose. The relay problems are not a hard fix if you know what you are doing and you have the right parts. Otherwise best left for a service person. If it is the hose it might be a bit more expensive to replace.

How do you rewire a relay

The relay contacts are wired in series with the motor, circuit breaker and switch. The relay coil is wired in series with the transformer secondary circuit, the control wires to the valves in the wall. Also the on switch is wired in parallel with the control wires.

You did not ask about the transformer but the primary windings are wired to be always on. If you need a picture I can draw you one.

see this step: God bless you
check.gif Check the house circuit breaker to see if it tripped?
Click here if you own a Vacuflo Central Vacuum Unit continuously trips your circuit breaker
If it is tripped, then turn off your central vacuum unit and reset the circuit breaker. Then turn the central vacuum unit on. If the circuit breaker trips again, then refer to the following:
check.gifDetermine if the house circuit your vacuum unit is on has sufficient voltage required.
check.gifIf your unit has a reset button, press the button and try again.
check.gifCross the low voltage wire from the relay at the unit with a small screw driver. If you hear the relay click you need to replace your motor.

I have a Ferguson step down transformer that takes input as 240V and outputs 115v The model is : TS 115/2000EC I need the wiring diagram for the output side

If it is 240 to 120/115, there should be two high side wires and two low side wires and ground wires, isn't that true?
Please post back, thanks.

Central vac will not turn off

Base d on your description... you have a defective internal relay, value $25-30US . It sits under the lid beside the motor and has generally 4-6 low and hi voltage leads plugged into it. Sometimes this component and the transformer is replaced by a new circuit board.Tag all wires with # position remove and take to a vacuum pro shop. Original relay may look different from the new one.

Electrolux model 2100

The power nozzle is equipped with a automatic shut off if something gets jammed inside it. Try resetting the button on top of the power nozzle after making sure the brush still rotates freely. A broken drive belt may also be the problem. You'll need to open up the power nozzle to check the belt. Pay attention to the screws as you take them out. One of them is shorter and is made to go into a specific slot.

Low voltage wiring

Probably just didn't wire the l/v side of the relay properly. Or forgot to plug the leads from the outlets back in to the vac after you got it all hooked back up. Folks do it to me all the time and then make like it's my fault! Ha ha.

Jump the l/v contacts inside the CV. If it goes: trace outward toward the outlets to see if something shook loose while it was apart. If you can't jump the l/v with a plier/screwdriver at the CV or even inside it, you have an issue on the board (either how you've connected to it or it's defective itself). The prob is that there's dozens of diff board configs, plus the relays and transformers weren't together on the same board in the old days. If you've got one of these models with a massive transformer separate from the relays get out the test leads and make sure you've got adequate voltage coming out of her to power the relay coil.
