Quick answer on mid position valve fault please

[OffshoreGas]

Just found this, would have saved working out the crappy diagram they give you. Explains it quite nicely.

Yep, seen that a gazillion times. I think you’re missing my point, what’s going on inside? I think it’s fair to say, going by the article I posted early this morning... that there’s more that goes on inside.

This any good to you?

Cheers, seen that though

Ok, what is it you want to know?

Which bit is it your not sure about? What the bits in the circuit diagram above are for or what’s actually in the valve body?

He’s not been back with the multimeter yet, so maybe it’s a case of wait and see?

Wiring diagrams, check.
Internal operation and resistance values, check.

Until I go back to the job and go over the wiring( re-wire centre) to ascertain proper termination and tightness, there isn’t a pressing issue ....yet. I could be like TFJ says ‘ a loose wire’
If it’s not a loose wire, what is keeping power at the synchron motor to burn it out in 3 months, seems the old tower valve has suffered the same death.. but maybe lasted a lot longer( I dunno, maybe metal gears) where as Honeywell maybe use plastic.

Anybody know the resistance across a known decent synchron motor, for reference

I haven’t used my free Corgi-direct one yet, I’ll test that when I have a spare minute, if you want?

Just the motor should be 2.2k or there abouts.

Lol, yeah I forgot about that..... we’re the fortunate ones

Have you still got yours then?

Nah, I used it a few days after I got it. It’s the same one I usually buy from an independent, but got that fancy corgi sleeve on it
