I've got a Rec active that's feeding a Victron system with a cerbo. The Active is connected to one of the VE.CAN ports with the can set to 500k bms. So far all good. The Zeus is a...
@Rick Yes, I know. I have good contact with Arco technical team, so will probably figure this out. Other than that, the Zeus is performing well. I have dual 12V275A on one motor, and I a...
Hey Trond, I am still a few weeks away from being able to test but will report back when I can. Remember not to use the black WS500 terminator anywhere as its on the wrong pins. If you ...
@PeterD Thanks for your input on this Peter. Some great troubleshooting tips :) We are in the process of setting up a full Master/Slave test system in our new shop. As part...
With Wakespeed WS500 you can setup the battery temperature sensor to work as an second alternator sense. I have been using this in 2 years and works great. Whatever alternator is hottes...
CANS is an command described in the manual for ABMS. It lets you change the bitrate of the data. CHRG is an command that lets you change the protocol and this command is not support...
I can for an short period see that it does see the data from REC, for an blink of an second. But only for like 1% and then 99% it does not sync. It even messes up the communication between ...
Has anyone found an solution here? Just swapped my Wakespeed for an Zeus and can NOT get it to sync from the REC BMS. I know the PIN-out is different from WS-500 to Zeus. Zeus and Cerbo ha...
I do agree 100 % with @Peter Domenicali and think that the corrected sketch he uploaded is correct. Thank you Peter for putting so much effort in. Nevertheless I would wish that either Rick ...
@PeterD got some work to do, great directions
@Rob Just to be clear, while I am certain about what I am showing in the Diagram PDF that I uploaded 17 hours ago, OGM Energy, represented by Rick, must be the final arbiter. After all, they are yo...
@Rob please be very specific about pin, colors on 14 end and 6 end on master/slave cable and what the correct diagram pdf is correct I believe that is where my problem is since bms#2 will not acti...
@PeterD the #2 slave would not communicate with master. #2 as a standalone was working fine. Then I was instructed to download the slave firmware to #2. I moved the wifi back to #2, and did so, ...
Martin, in his original posting above, correctly identified the wire colors and meanings connected to the DB9: Pin 1: Black cable = Shield Pin 2: Gray cable = GND Pin 3: Green cable = RS485 Sign...
@PeterD so guys what is correct ?
Hi Rick and Rob, With all due respect, Rick, I believe you have the two "+5V" lines mixed up. Looking at the product manual from REC, the pins are all clearly described, and I have verified the wi...
@Rick will check it out
Just updated DB9 pin numbers and added a Slave to slave pinout section to the Master Slave Pinouts diagram. Thanks to PeterD for catching it. You can download it here: https://rec-bms-...
@PeterD ... so looking at the plug from outside which pin gets what color. Big trouble here need help Solar@robtribble.com
@PeterD .... I am in the middle of the same problem. Master & 2 slaves. Could use some serious help Solar@robtribble.com
@tom look under devices/rec/pArameter/CVL. I think here you see 13.4 /13.3 means REC send a float voltage to your charger. This means bulk 14.0V was finished. If battery is discharge to 95%, it w...
ben, i put your settings in exactly. now it stays in absorbsion at 13.32v at 98 percent i must admit, i am getting confused.
Ok, I found something curios.force tach mode is "3"set it to "1" and then saved/download to the WS500, but it does not accept this.Changing the other settings is no problem. I am using the O...
Thanks Rick. But as I wrote I have enabled firce tach mode and I tried several values for min field including -1 for automatic detection. unfortunenately this works only for round about 10s after...
and a bit more info from page 68 of the WS500 full manual, release 2.6 Tach Min Field: <WHOLE NUMBER ( 0 à 30 )> This is the % value the PWM will be kept at &n...
I havent had a chance to play with the recent f/w updates but its likely the issue is that you will need to set a minimum output on the alt. to provide enough of a sine wave for your alt to see.&nb...
Hello, I have the problem that the tachometer stops working as soon as the BMS sends the "disable charging" signal via CAN. We have installed a WS500 on a Balmar alternator. The WS5...
@Rick When you get it setup let me know. I think I have what's needed to support the Q series but I don't have one to test. So far I have serial able to read all data points and able to send a...
@o-firstname This looks great! There are many hundreds of marine REC users but we don't have an easy way of adding them to this post. Let me see what I can do. I have a spare...
Does anyone here use their REC BMS in a marine settig with SignalK? I just finsiehd the serial side of a SignalK plugin for the REC BMS and I need a tester with a Q series BMS.
another question about float. is it even necessary to float lithium batteries? online it says it is not necessary. so staying in absorbtion is not an issue or not? &n...
Hey Ryan, We are setting an inhouse demo using a big marine generator as the test system and are just working on wiring and setup now. This will allow us to try a couple of head to head test...
@Ben I though you had the suggested settings already, seams not yet. That explains you see 13.69, your system is in float, with a wrong , a bit high float programmed. I have sent ...
We have also created a REC 2Q/Cerbo Interface manual. The Active BMS has an update 2.9.5 coming that will standardize commands between the Active BMS and 2Q and in a few weeks and we will upd...
I will make the changes later today. It is 440am right now. Thank you Soc shows 100 now before I make any changes. Thanks Tom
@tom did you make the new settings? After that, switch BMS off and on, to start a new recharge cycle.
