oops, sorry forgot all about it !

I'll sort out a diagram later on when I have a min

when it's mounted on the wall, normal mains power (positive) goes into the top contactor

E7 power (positive) goes into the contactor underneath is

negative and earth go into the rail mounted connector block thingies at the bottom - iirc, the earth one was a bit full, so you could earth to the box with rig terminals where there's already an earth connected there :-)


all the heater/pump etc.. wires are labeled up, so you should be ok with those ones


remember to use decent thick wire for the mains in if you want to run 2 (or 3) heaters at once!

Ta muchly

Any luck?, the electrician put the E7 and mains to it today and dropped the front panel, which has pulled a wire out and im buggered if i can work out where it goes

[knighty]

I had a hunt for a photo but this is the only one I could find




I'm sure I had a better quality one than that somewhere but can't find it anywhere  :-(


can you take a couple of better photos and I'll label them up ?

[K.H]

Will do

[K.H]

This is the black wire i released from captivity, at the mo its poked in where i thought it may of come from

[Julian]

Far be it from me and all that, but would it be helpful if you identified which end you "poked in"?

[K.H]

Err, top one i think, it wasnt actually me, the leccy dropped the front that pulled it out and told me he had put it back under the only slightly loose screw he could find, but helpfully informed me that he couldnt swear it came from there

[knighty]

erm... I have no idea

can you get a top down photo ?

it looks like it's coming out of the timer and then going into the input of a contractor... which is wrong

but... it's hard to tell from the photo.... it could be that it's coming out of the timer and powering the contractor on....


I'll be able to tell from a top down photo

[K.H]

These are all the pics i have at the mo, can take more if needed 
BTW the pressure/float switch what will it cut out if activated?

[Julian]

Oh, this is getting tedious.

Just connect it to earth and switch on ... what could possibly go wrong?

[Tony]

You might let the magic smoke out

When can you nip over and hold the metal box, i promise to disconnect you with a large piece of 4x2, it would be my pleasure 

[knighty]

if you can get a top down photo of the green timer relay, I'll be able to tell where it's connected in, and what it's supposed to do :-)

I think/guess right now, that it's probably the negative feed for the timer, and the electrician has knocked it out when he's been wiring in the main negative feed ? (no biggie, it's easy done)

the float cuts out the negative feed to the heater contactors for the processor, so cuts off the processor heaters


EDIT: WAIT !

don't turn it on

unless he's re-wired them to suit... he's wired the main feeds into the wrong side of the contractors !
(I'm only suggesting he might have re-wired them to suit because it's such a school boy error!)

also... can you do a photo of the whole box... it;s hard to tell how he's wired in the negative, there it looks like he's joined them both together with a connector block, and then used another connector block to join a spur to the pumps and then maybe run a small wire to the negative terminal block... if he has... that's no good at all.... you'll have a min,. of 26 amps running through the negative when you're running 2 heaters at once....

where do you live again ?

I could see if I'm coming anywhere close sometime ?

I tried to lay everything out as cleanly as I could, but it was a bit tight fitting it all in the box, and the PIDs sticking back into the box meant I had to squash everything around the sides a bit


main feeds in must be wrong... it's wired up so the transformer for the washing machine switch, and the SSR both have a permanent feed from daytime power, and no power from E7 power

major schoolboy error... was he any good ? I know it was a bit full in the box... but anyone who's every worked on electrics would have been able to see all of the outputs coming out of one side of the contacts, and that the other sides of them were all connected in parallel... it's standard practice for connecting up stuff like that...

[Tony]

This is definitely going to be one of those "death or glory" moments when the power is switched on
