I'm finally setting up the shunttrip on my system and have hit my first roadblock :huh:

I have connected power to expansion board.

On Daniel's vid



At around 1.25 the drop down in Menu - Hardware shows critical fault.

Mine does not. What am I missing here?

Different version i assume. I cant check right now though.

I will try and update the software
Thanks for quick repsonse :)

Yes it wasan old software issue.

There could be more questions :p
 
Ok, I've been working on this all day. It's been a big deal for my skill level but hopefully all good when I flickthe switch
:s
One thing I'm not sure on is the wires coming from shunt trip to pins 11 & 12 on expansion board for relay 1 control.

1.Is there any polarity with these?

2. Do i need to fuse this line?

3. Is just thin wire as in photo ok?

The shunt trip is just DC, if I remember. I don't think it's polarity dependent as it's just a magnetic flip (i think, if i remember correctly). The thin wire gauge is fine. Looks about the same size daniel used in is videos. And I don't think he fused his, either. It's just going straight from the batrium to the trigger, so you should be fine.

But, I could be completely wrong here :p

Sounds right and what I was thinking.
Thanks ?

Yeeha
No magic white smoke :)

No finesse yet but we have function!

Just have to test shunt trip and shunt watts reading 0. I think someone else had that after software update, will check that later

This forum and it's members are very helpful, just sayin
 
Ok, I have shunt watt reading back but the shunt trip aint tripping.
Is it something to do with these output settings?

I also noticed Peter is getting power from different pins on expansion board??
He is using same shunt trip as me.


Around 7.44 on vid
 
Have you setup the critical fault values? Ie voltage, temperature and so forth?

Yes, if you mean the settings under critical in control logic.

Well I haven't done temp but voltage yes. I did a test and changed threshold to lower than actual and it didn't trip?

I noticed in your vid you bring in external power for the shunt trip,s that right, could this be the issue?

Also on Pete's vid he is connecting shunt trip to pins 8&9 on expansionI think, I've left a comment on his vid
 
Pin 8 & 9 is a 12v mosfet output... you have to use a 12v relay controlled by themosfet outputto switch the 48v shunt trip... (check the voltage of the shunt, if it is one from batrium it needs 48v to trip )
If you use a 24v shunt trip (asme)you can use one of the relay's of the expansion board instead.. (these do max 30v)this can be set in the software.

I'm using this shunt trip

Connected to pins 11 &12 on expansion for relay 1
I must be missing something?
 
You cant hook it just to the relay like that. The relay only relays stuff.. It does not power anything :) The mosfet on the other hand works differently. For powering via the relay you need to feed in power. The relay is like any switch you flip on and off

So what will be the easiest way to get this working. Id prefer to power it with the system
Thanks
 
1) Select a relay (drycontacts) on the expansion boardto activate in case of a critical fault in the sofware.
2) Connect the relay's contacts in "series" with the coil of the shunt trip.
3) i have used a "middle connection" of my 48v battery setup to get the 24v to power the shunt
4) connect the power also in "series" with the relay and shunt.
5) test the cr*p out of it. and do not forget to put a fuse in the 24v powerlines. :)

This is how i done it now, and happy with it.

In the sofware you can select a pulse or on/of activation of the relay, check what you need...

You can also, like daromer did, use a voltage devider (2 resistors) to get the 24v needed.
 
One resistor is enough.

Thanks so much. I think I understand that. Electronically challenged here;)

I'll get back to it in next couple of days.
 
I know that the relay is only 30VDC rated but I still dont think its wise to hook stuff in middle of battery bank as first choice :) Im afraid people start doing this with devices always in ON state and this will cause issues. SO just beware of that!

Doing a resistor same as the relay and then hook it onto the full range is not an issue and will save alot of grief in the end ;)
 
You are right, it is not advised to hook stuff up on a middle connection of a battery bank !! ... it will be the cause of unbalance in the bank.
But in this case it is not a real"load" that is connected, just a little coil activated in case of a disaster for a split second... i dont thinkthis is a issue.

In the part, responsibleof disconnect in case of a fault, i do not like to have thingswhich can fail... :)
That sayd, a resistor is alsonot likely to fail... Soooo

The value of the resistor has to be the same as the R-value of the shunt-coil... And Daromer can advise on the W - value of the resitor.;)
Both drawings will work just fine,the oneyou like the most wil be the best...

And as always, you have to know what you are doing before playing with these things.
 
Thanks :)

Im still pending some info from Jaron about the shunt trip and how to wire it all up so i can complete my shunt series...
