gammel kontrol (v.4?) ekstern skrue tilføres uden pause, change to v7

[kao]

God aften,

(Google translate, english below)

Jeg har et problem. Smelterøret er smeltet. Stikket fra styringen til brænderen er brændt. Så jeg har brug for et nyt bestyrelse. Sikringen i controlleren er sprunget. Efter udskiftningen pumper den eksterne skrue straks og uden pause, så snart kontrolsystemet har strøm igen. Er kontrollen også brudt? Kan du nulstille controlleren? Kontrollerne er stadig meget gamle. Jeg tror version 4. Brænderen er ikke tilsluttet. Displayet viser ------. Årsagen til branden er elimineret.

Heldigvis kan du også opvarme Woody med brænde.

Mange tak

Good evening,

I have a problem. The melting tube has melted. The plug from the control to the burner is burnt. So I need a new board. The fuse in the controller has blown. After the exchange, the external screw pumps immediately and without a break as soon as the control system has power again. Is the control broken too? Can you reset the controller? The controls are very old. I believe version 4. The burner is not connected (because i want to know what i need before i order spare parts, i can not test it, with burner). The display shows ------. The cause of the fire has been eliminated.

Fortunately, you can also heat the Woody with firewood.

Many Thanks

Hmm

We don't know how much is burnt and how well the burner print has taken it, but you seem to have an issue and i think your burner print is shorted and your solderpoints have failed..

The V4 has a Red dot display, but you could also have the 4.99 woody thats a bit newer that has the green display i believe. I would bite the bad apple and go for a upgrade to V7 with new burner print, if the rest of the system is okai to reuse.

It has a red dot display. So V4 is probably right. The plug is baked into the print, definately beyond repair. I will order V7+new print tomorrow and hope the rest survived.

 You will need to do a bit of retrofit and you need to fix a conversion plate to the burner and so on. But getting the full kit should contain it all. You just need a tool for the shrink studs (dunno the name) to fixate the 12pin to the burner print and fix the wiring to your setup.. You will be happy with this upgrade im sure..

You need to find out why this happened.
-   Was the boiler / chimney blocked
-   Does the internal motor/gear for the screw conveyer work properly ?
Check if you can hold the screw conveyer with a plier, while engaging it
(all condesators should be replaced app. Every 5 years)
Are the screw conveyer properly connected to the gear motor

The new controls are better than what you have, but you need a new burner print
i think it is this one, but you better call and ask

Control:
https://www.hedestoker.dk/4305-version-7-styring-med-internetadgang.html
This adds up to around 4000 dkk
If your burner is to big for your consumption, and / or have other defects. It might be a better deal to replace all of it

I have a V7 now and all new parts for the burner, but i need some help.

1. I have the old design blower (ecofit 2GREA3 108x52r), which has only 4 wires and the manual only describes the fitting for the new design with 5 wires.
    Black - L2, Brown L1, Blue N, Yellow\Green PE should be right?

2. I have an external control that should switch the v7 on and off. In the v4 it was connected to Kontrol +|-, in v7 i have Kontrol K1 |K | K2, which is plus and minus?

3. Can i not connect my lambda sensor to the v7 without the expansion board?

Ext print must be used for lambda probe.

2. You dont need the external as such. When clock control is on for the heating you have the blocks off and it will work the same, i used my V6 with the external, but just took the jumper out each time, but with the V7 i just have it all off in clock control and it stays dormant that way..

3. I did not know you had a 02 sensor. But that runs on a separate box too with the V4?. If i can be reused and i don't really know or how V4 had 02 implemented. But yes a brakeout board is used with the V7 to run O2.. You can adjust it without and leave it out and i dont use it myself..

Thank you i have everything connected except the external control. I need that because that controller has to tell the v7 when to turn ün\off. In v4 it displayed OFF3 when in stand-by. The external controller manages everything like solar, warm water mixer and has all the temp sensors for the tanks etc. So i need it to be in charge i guess.

Google translate makes i more confusing unfortunately.

It was connected to external cut off. One the board it is polarized + | -

https://www.nbe.dk/wp-content/uploads/2015/08/manual-V7-og-V10-UK.pdf page 17
external on\off is on K1 K, but it says nothing about + | -
So im not sure how to connect it.


The lambda sensor for v4 needed an extra chip placed on the board, but it just showed O2 level, didnt regulate anything by itself. So i can ignore it for now.

Polarity is not important, just wire K and K1 like you did on the V4 and find out if NC or NO triggers the V7 to shut down..

First of all thank you all, i got the burner to start.
But soon the next problem came up
The external screw is very oversized and in the v7 the minimum values are to big, is there a way to override the minimum?
In 6min the screw provides 22,5kg of pellets...
The max number i can input is 19,99kg and even then the auto calculation gets numbers which are below the minimum. When using auto calc ignition works, but after about 15min the flames is put out by too many pellets.

                       autocalc for 20kg       
at 10%               0.21%                 minimum 0,5%
at 50%               0.8%                   minimum 1%
at 100%             1.6%                   minimum 1,6%

You don't give of 22.5 kg im pretty sure. But more like 2250g = 2.25kg.. Mine goes to 19999 g and that is 20kg and no external pellet auger i know even get close..

[kao]

No it is 22,5kg, i transfered it to 15kg pellet sacks and got 3 half full, then weighed it. 22,5kg. As i said, it is well oversized. But i worked fine with v4.

Uhm hmm well that is weird and a lot to take in and it will make the dosages really hard to get that accurate.. But you are stuck here with offdosages that wont be accounted for.. How big is the burner.. 16 30 50kw ?.. I would get a auger that makes more common dosages of 1000-2500g.. And it would be easier for the burner to digest it too i guess..

[kao]

I still have the original auger that came with burner, but it is too short to reach the silo (next room). If i cant find a solution, maybe i build a small secondary silo next to the furnace. The big one can fill that then. But that is more of a long term solution
