Yes, the green light is flashing on the slave. I've tried more settings. It doesn't work.

are the green LEDs on the slave blinking about once a second? Are you using addresses 16 and 1 to try and connect?

I'm trying to establish a connection with the slave using the software. Unfortunately, without success. Can anyone help. I can't reach the slave, address 1 and 2 are not recognized. What's wrong he...

@Trevor really strange.  I have 2 setups running with 2.94. Non off them have any problem. suggestion to test, with 2.94. under settings/manual communication. Type address: 2 Type command:...

Cool! It sure looks a bit more professional than my relay interface boxes that does more or less the same thing. When do you expect to have this on the market?

@Sturla The "Quick connect TBS" is a new product, not yet on the market. Some functions: -connect bms, 4 wire only (ATC+, ATD+, + and -) -Connect easy 2 TBS relays -connect a remote panel, whic...

@Ben I relly like this install!  One question; What is that TBS "quick connect" box? Link?

@Johan For the ABMS, firmware 2.94 Main relay, can be set for ONLY Low voltage protection, program MODE at 2. (parameters under settings are used) Main relay can set for LOW and High voltage pro...

Rick, Thanks, but I would be able to use both main relays? and set both relay parameters for open at low cell voltage? Then I would only need one Opto relay for the third Tyco with use of an relay ...

Thank you both.@Trond Røsvik, your diagram is how I had both shunts before removing the alternator positive shunt. I had the wakespeed sense wires on the alternator shunt too.@Ben , I'll get...

Using the Wifi module and in the Tasks section you should be able to configure a different dropout voltage for each.  You should have 1 available relay that will drive the Tyco directly and y...

Did you try changing the CANS parameter to 2 or 3?

@Ben Thank you, I tried again this morning and when I successfully install 2.94 the REC disconnects from the Cerbo, I don't know why. I switch back to 2.93 and it works perfectly.

@Johan holding power 0.13, but switching ON power?   Maybe others in this forum  have experience with switching Tycos. I don't like relays that use 24h day 0.13amp.   The ABMS, ...

Hi, The Tyco relays 9-36V use 0,13A Holding current. I want to set differnt UV settings on all three relays if possible. I also have one Pre-charge unit.

@Johan page 4 from manual mention, the internal relays can do 0.7amp. Check how much current your Tyco relays use. You can also have REC, BMS switch on 1 Tyco, and the other 2 Tyco, switch on by ...

Hi, Can I have three Tyco power relays (12V) connected to three differnt discharge busbars that shall open on Under voltage? Which relays in the BMS should I then use?  

Good clarification on this Ben. I think Trevor misunderstood your CANS (CAN speed) reference and thought you meant device address. Trevor, your CANS parameter should be set to either 2 or 3 depen...

I used a 2.94 from another sourse as from https://rec-bms-na.com/product-manuals/#7-8-wpfd-rec-active-bms Now I downloaded the version from the link above.  Installed it,  it worked pe...

@Rick I just reverted back to 2.93-1 and the REC immediately showed up on the Cerbo.

@Ben Hi Ben, yes the Send address for communication is set to 2 still. The system has been running great for over a year, it was just the update that changed something, can't figure out what it is.

@Trevor check in manual communication  CANS? Is it set at 2? If not send command: CANS 2  Check with CANS? Again. My system runs nice. Your reset the mppt and others chargers to get ...

@Rick It did not. On the Cerbo under BMS - Can port it's just reading REC: N/A

Head office just advised us of an issue with 2.9.4 and we just posted a rerelease of the update here on the REC North America site https://rec-bms-na.com/product-manuals/#7-8-wpfd-rec-active-bms ...

I just updated my Rec A BMS to 2.94, and immediately afterwards my Victron system lost communication with the Rec. I have a Cerbo GX, Multiplus 12/3000, Smart MPPT's, Samrt Shunt etc, all has been ...

I have made an modified drawing from the REC BMS manual, just to show the placement of the two shunts really.  REC has to be at the battery minus, and WS500 at the Alternator plus.  When...

@W the profit from DVCC is that when cells are almost full and cells have a slight imbalance, the charger start adjusting the charge to avoid one cell goes to high.  Much better for the cells...

Just FYI for whoever may stumble across this post, I removed the shunt, reconfigured the wakespeed to not use DVCC, and disconnected the wakespeed sense wires and everything has returned to normal....

@Trond Thanks, Trond. I appreciate it. I do have an agm battery in the system to absorb voltage in case of a battery disconnect to protect the alternator. It is joined with the alternator positive ...

The alternator is charging 3500W and the WS500 is seeing this correctly, and now positive reading so the shunt is also the correct direction. The battery is still showing 0,3A so the current from ...

@W To move a shunt from negative to positive will not solve the problem you see.  The WS500 only monitors the shunt, it does not matter or that shunt is in negative or positive.  IF the s...

As far as the resources go, I'll take another look at the links, but as far as I know, there's nothing in there specifically about the Rec and how it plays with the Wakespeed with DVCC turned on. I...

@Ben Nope, the new alternator shunt is on the alternator positive cable. I've also tried it on the alternator negative without success. The battery positive goes to a 400 amp T-fuse block, then to...

Here are some links, which you maybe have missed on the Wakespeed website. https://www.wakespeed.com/learn/ https://www.wakespeed.com/wp-content/uploads/Wakespeed-Victron-Cerbo-GX-Guide_4.29.24-1...

@W the shunt from the ws500, looks like installed in the main positive from the battery!!   The shunt need to be installed in the positive from alternator. (As in manual is discribed) In th...

Just changed the alternator shunt to the negative wire from the alternator and it's still listing it as a dc load and alternator power. The original shunt with the Rec sense wires is still in place...

Yes, it was showing the alternator with negative current as I was playing with the setting on the app trying to figure out the doubling of the dc power. Even when I correct the alternator setting p...
