here is an update on the controller for the interested,
after pulling it all to bits again, cutting the box down to size, making a lid and reinforcing the bottom with a piece of 1.2mm sheet steel, giving it a sand down and a few coats of paint, then re-installing the switch gear, it was time for joining all the bits together with copper wire,
I asked a few questions about a few details in the wiring and the electronics tech.( that lives up the road ) came for a visit and gave me a hand to wire the box and to change out a capacitor on the PWM circuit board to reduce the SSR used in that function from overheating. As advised by Swede ( thanks Swede for your assistance, you have been a champion :handgestures-thumbupleft: )
this is what it looks like at the moment :shock: :shock: :? :?
It has all been tested and works as per the plan ;-)
to give you a run down of the front panel :geek:
starting from the top left
red light indicating that power is on at the wall isolator, a big red emergency shutdown button, red light that indicates the controller is switched on ( via big red "panic " button ), PWM control, ( a type of throttle controlfor the 3600w element, for the uninitiated :laughing-rolling: ) and last on the top is the 2400w manual override/ on-off switch
bottom from left
P.I.D controller for 3600w element heat up/automatic temp holding and alarm function ( used to turn off 2400w element once a preset temp is reached ( it doesn't come back on ), next is the, PID control (auto) - off - PWM control selector , a green light indicating 3600w element on/off, green light indicating 2400w element on/off
below the PID are the temp sensor terminals, the power outlets for each element,green lights and switches above them are all lined up vertically ( fuck.... I think thats right :think: , If its wrong can someone let me know :laughing-rolling: :laughing-rolling: )
All I have to do now to complete the controller is zip tie up all the wiring to make it all neat and tidy !
now I have to turn my attention to the boiler itself ( when time allows :angry-banghead: )
to be continued
cheers
