Please help: injection wiring

13/02/2018 at 16:14

hello guys,

I am trying to figure out the wiring for an injection machine.
I have bought the components, but not sure if I do it right.
I am using 220V single phase.

Would somebody help to confirm or edit my drawing?

Thank you

its to hard to read for me

12v has red and black wire with + and –

220-230v has brown and blue wire with pase and 0

but that is in holland

blue wire is phase and needs the switch

afther a swich the blue wire becomes a black wire

and i dont see a earth wire, do you want to ground the machine?

I THINK THERE IS SOMETHING WRONG, input 230V ac go to pin 5 and 6, no polarity, OUTPUT 12V go to pin 1 (+) and 2 (-) , I think the relay is not the correct one, please put the list of your components and the related voltage 12v dc or 230 ac and I think it will be possible help more.
Check the PDF files.

Thank You @basman,

I am just following the diagram in https://preciousplastic.com/en/videos/build/injection.html

and I got lost =D

Thank you @fabirihotmail-com

I adapt the diagram on the blue background from https://preciousplastic.com/en/videos/build/injection.html
Then I applied it to the components (on the white background)

The component I use among others are:
– Autonics Temperature Controller TCN4S-24R
– Autonics SSR Relay SR1-1425.

Hello @davehakkens,

Could you give me some enlightment too please.

Thank you

I think like this is correct but my only one doubt is that you have to connect the pin 3 and 4 with the output of the relay but I am not sure…

thank you fabirihotmail-com

rather different from the original scheme?

Here’s how I’d wire it. I’ll admit that i’m not an expert but i’d rather have the switch kill mostly everything inside the box. Here in Indonesia ground is typically connected to the neutral wire which makes touching things a bit exciting at times.

The wiring in this drawing is based on the diagram on your temperature control unit in the photo you shared.

I change 1 and 2 with 5 and 6 and vice versa, I think is good like this… I have watch videos and it looks correct.

Thank you @bulegila,
Thank you @fabirihotmail-com

Here is the revised schemes.

Which should I follow?

thank you

@Enricoah NUMBER 2 corrwect polarity on the relay.

how did you solve your problem? what scheme did you follow?
