ATS working in manual only ( No auto)

[Pink7]

Today im testing out the ATS before prepare to mount it up. I connected 2 wires to house grid power as 2 power sources and outpower to a light. All working when turn switch myself but there is no auto switch happening. When i remove the active power source it just close the light. Any ideas whats wrong? Auto/manual option is set to auto.

U got the manual? (or any documentation)

 

No experience of that switch but I think there's supposed to be something connected to that green connector.

I have no manual. There is some info on lazada.

You could try contacting the seller (yeah, right)

 

Are there any markings on the green connector?

 

Try connecting it like this (all three L connected together): -

See that little bank of connectors on top (think they're green). They do effect how the switch works. Maybe they have nothing to do with your problem, but with my ATS the way they are wired effects my ATS operation. 

I have my ATS wired like Crossy's diagram then I wired the connectors to send an earth to auto start my genset.

Not the same ATS as yours.

Here is details from the top part.

Can you post a clear image of the switch part number please?

It's on the front plate, just not readable in your earlier photo, need to try Googleing how to connect.

I see some other ATS connect to those green connectors: example

[Crossy]

Yeah, I see that too, but it's unclear exactly what your green connectors do and connecting them incorrectly could fry something.

 

Try this.

 

With it connected as you have it.

In Manual set to OFF

Power on the Normal side.

Switch to Auto. - Does it move?

Power on the Reserve side

Power off Normal side - Does it move?

 

EDIT and message the seller of course ???? 

 

EDIT 2 Have you got a load on the output?

Inside the ATS there is a relay, a motor and two main MCBs.

The relay is powered by the "N" circuit I think and will remain energised until power is lost at that input.

When the relay is de-energised the motor is powered to cause the MCBs to switch over to the "R" circuit.

The opposite happens when power is restored to  "N" input.

 

Make sure the supply to the "N" side and the "R" side is good.

They are nothing to do with the basic function but are volt free and can be used for gen set starting.

Ok i will test that, thanks

Yeah, that's what I thought, but then I read on one of the pages for similar switches "this switch can not be used for generator starting" ???? 

[Crossy]

And of course, it's always possible it's busted from new ????

I do note that you possibly have L and N (colours) connected differently on each side.

Tested it now after change the wiring with no changes. My testing is with 2 pole connector so how it connect N to what house power wire is random.

Not on mine but I suppose different switches can do different things.

The installation book is the definitive source for this info.

Needless to say those green connectors can be left alone for a basic change over function.

Please make sure that the output side is wired with the two neutrals connected together and the two lives connected together like in the drawing.

Ok, i will re wire all and also be sure use 3 pole connectors so all connect correctly. Update will come later

i think same you because changeover motor inside is 220v and using only one phase and neutral

 

for single phase use best link all phase together because not sure which line inside circuit use for 220v control

@Pink7 I have a very similar looking transfer switch which was installed by my solar installer.

 

It features in this video on V2L at about the 4 minute mark.

Latest changes done and now its working, connecting all L ports in top was the key.

 

 

Thanks to all who contributed.

Thanks. Another interesting thread where I learnt something new.
