Keenovo 220v setup

How have you connected the SSR to the Duet? Have you connected the + and - control input wires the right way round?

Duet3 (out0) instead of Duet2

Hi,

Did you verify that 220 is present on the L and N wires?

@fcwilt
No, with a tester ?

I was just wondering if that power switch was wired/working correctly. I had one that was defective.

Do you have a device that you can test for power on those wires?

@fcwilt
No, unfortunately

out3/4 should be powered ?

[dc42]

If it's a Duet 3 then OUT0+ is powered from the +VOUT0_IN input terminal, not from +VIN.

[Touchthebitum]

@dc42
Yes it is a Duet3.
So I should power out_0 power in too from the PSU ?

The SSR does not take a lot of current on its input, you can use a thin wire and one of the fan headers to simplify your wiring. Keeps your bed output free for things such switching LED lights...

@pixelpieper
Ok, thanks but not sure I understand ..

@Touchthebitum I just had a look on the wiring diagram of the duet 3: you can configure your bed to use for example out 2 instead of the big screw terminals to control your SSR.

@pixelpieper
Ok, thanks

@Touchthebitum Here is a sketch with the correct polarity for the SSR inputs:

You then have to adjust the configuration as follows:
M950 H0 C"out2" T0 ; create bed heater output on out0 and map it to sensor 0

@pixelpieper
Perfect
Thanks

@pixelpieper
Great it works like a charm. Thanks

[pixelpieper]

@Touchthebitum Nice!

You're doing mains wiring without a multimeter?
I'm shocked, but hopefully you aren't!

[Touchthebitum]

@Phaedrux
No, I misunderstood the question, I mean I'm not very clever with it

A side note about multimeter usage, if you use it for mains voltage, you want something better than the check multimeters from China, regardless what their specification says. There are all kind of costly safety consideration that go into a good multimeter design. Stick with a brand name (there are several, Fluke is not the only one).
