Cyclovac DL200 clicking relay noise when turned on

[Cyclovaccer]

Hi Folks,

I browsed the whole internet to find answers to my current problem with my 19 year old CYCLOVAC DL200 (240V Version). Here is what I did recently:

- one of the motors failed suddenly so I decided to replace both of them
- when trying to turn on the vacuum cleaner the engines run for a second and the circuit breaker of my house installations releases
- I installed an external inrush current limiter to my socket and everything worked fine for about two weeks
- today suddenly the vacuum does not run anymore, when turning on the motors run for a second or so and all you hear is a contnious clicking noise of the relay

What I tried was:
- only connecting one motor ==> no difference, still clicking relay
- measuring output voltage on the electronic board ==>235V, okay

Any ideas what might be wrong? Can the relay be defect or rather other electronic parts on the board? Since both motors are always start running for a second when the vacuum is turned on I would guess the engines are okay?

Any help is appreciated,

thanks Tom

That sounds like a circuit board replacement to me. Does it have Datasync? And finally could you please upload some photos. Good luck!

 

[Cyclovaccer]

...yes I think that would be necessary. But there is no source found on the net that offers such old hardware for the DL 200. Here is on picture of the board - does not look to bad I think. Just let me know if other details help - I will provide more pictures....

Hope this helps!

thanks for your help - but I think that is not the right one or am I wrong. It says:

• For Cyclovac central vacuum units:
  • DL210SV
  • DL410SV
  • GX910SV

 

[centralsweeper63]

Ah, sorry. Maybe try search terms with your brand and model. As well as 240v.

Whenever I have an electrical headscratcher like this I have learned to confirm all your grounds are clean and tight.

 

[centralsweeper63]

True.

Whenever I have an electrical headscratcher like this I have learned to confirm all your grounds are clean and tight.

..absolutely, but in this case I am 100% sure everything is okay - but just checked once again and setup here is pretty simple - checked with voltmeter and should be all good.



What I meanwhile tried was as follows and brought new insights ;-)

- connected only one of the motors and plugged the vacuum directly into the socket without the current limiter ==> runs
- connected only the 2nd motor ==> runs
- connected both again ==> circuit breaker goes active
- bought a new current limiter ==> cleaner runs but in 1 /10 starts circuit breaker still goes active

Sounds a little strange to me....

Had my old Hoover CV been designed that way, I could have wired in a new relay board.

Circuit board are more or less the same, except for their voltage and their amp rating. How many amps does your unit use?

 

[Cyclovaccer]

Should be max 10A for both engines:

Technical data:
Motor TypeSMO.116 036-00
Rating Voltage（V）230
Rating Frequency（Hz）50
Rating Input Power（W）1100
Maximal Airflow（M³/min）3
Maximal Suction（Kpa）30
Maximal Air Power（W）560
Maximal Efficiency（%）35%
Noise（M）（dBA）≤85

You will need to talk to them about international shipping to see if it is possible, though I can imagine it is at a cost.

 

[Cyclovaccer]

Wow! Amazing research, thanks a lot! I texted the Shop to verify the biard fits to my DL200.

Shipping should be possible, I have some good contacts overseas

 

[centralsweeper63]

Good to hear. That is an amazing company for all your central vac stuff.

There is no need for a 240 volt board in the US where the voltage is 110-120 VAC. That product is meant for export and MD is a great company to deal with. They are about two hours away on the other side of the Sierra Nevada Mountains in Bakerspatch ( Bakersfield CA, home of the Buck Owens Sound ! )

 

[centralsweeper63]

The OP is from Germany though.

Correct. A 240 volt board is not meant for a US model central vacuum. That is for an export model, which is why I think it is safe to assume MD will ship it abroad. There is no market for that part in North America.

 

[vacerator]

There are 240 volt US models. A transformer on the circuit board rectifies the voltage to 24 volts d.c. I couldn't repair my Hoover because the breaker reset button was integral on the board, and the hole for the button did not allow enough clearance for an available current aftermarket board and button both.

 

[centralsweeper63]

Think of your oven or dryer, they are very likely 240v, new builds often get 240v central vacs.
