Heart invertor not charging???

[Joe Camper]

Bob is the heart interface logo on the front in blue or red on yours?

I see you have colse to the same age bus and ours is the older unit case is identicle but labled in red

If it is labled in blue does it have EMS on the front access panel or does it say freedom?

I think there is 3 different configurations all on that same case. We have  the original in our 85 and it is red and that's how we know for sure. But then there was the freedom AND the EMS and they too are little bit different too but not much really.

Toms I think is an EMS and the only place the case is marked with a model is on the front access plate if I guess right toms is model EMS 2800-12 or 24 whatever the case may be.

The freedom is also labeled in blue I have not had one of those opened but may be similar to ours. where the medium size transformer is mounted to the inside of the case on Toms photo there is a similar sized relay/switch instead (often clear). On toms the the big red and blacks and white go to the relays on the motherboard but on ours that relay is not intigrated ito the board it is seporate and the a/c commons and neutrals will be going in and out of it instead and the motherboard will not even have relays on it.

If yours is red like ours you have an older one ours is actually labled correctly at the bottom in the back and also on the front cover  HF24-2500SXWF  

Another dead giveaway is on the EMS the d/c goes in and out the back and the a/c goes in and out the front bottom.

On the old red ones they both go in and out the rear.

I can tell you for certain without a doubt that the older ones are way more powerful and officiant than the later models. The EMS drags the voltages down way quickerone we have I have had to use the EMS while we were fixing the other and it was quite different

Joe, mine says EMS on the front & Freedom somewhere else. Also, some of the paperwork says EMS2800-12 & some says Freedom or Heart. I didn't realize there was that much difference.  If they were trying to confused the issue they were way late as I was already confused years ago..     Thanks for the help & I will call & find out what's up.

Mine is white lettering on a black case - Heart Interface Freedom 25.  On the inside there is a long PC board, somewhat like Toms but there's a mounting panel built into the case, as I recall parallel to and immediately behind the front panel.  On that panel are mounted the relays and they are great big heavy duty relays - again as I recall there are 4 of them BICBW because three would seem like a more logical number, unless the fourth one makes the green/white bond.

Yes Tom I recognized yours because I have 2 of them here and it allowed me to compare the differences between the EMS  and mine.

It will definatly say Heart interface and EMS and be lettered in blue and is in the identical case as the older model we have.

Now that I went back and looked into old photos the Freedom series is not that same case it is different than yours and mine.

Call that number I gave you and you will get it straight.
