@Christopher , The max charge, float setting en recharge settings is just one example to get the system running. You can change this settings to the settings you like yourself.
@Christopher , The max charge, float setting en recharge settings is just one example to get the system running. You can change this settings to the settings you like yourself.
@Christopher I put your settings in a calculation sheet with the formulas from the manual. Result in: Bulk charge max 14.18V Float 13.08V Restart charging, if below 13.04. If you volta...
I did a test. Installed a fresh downloaded firmware. Made the suggested settings. All worked. (I use a test setup, with 4 LED to monitor all outputs) Advise, double check firmware version. Aft...
@Ronald For me is not clear which minimum voltage you change in your test. If you did this in Task under relay1, then you are programming relay1, as a "low voltage" shut down. Not what you w...
@Ronald the opto are other outputs, see manual.
@Ronald There are different manuals, I don't know what your pag 7 shows. About the settings from previous post. Under task the settings are for charge relay, use cable marked with C...
The setup you describe is "separated charge and load bus" You need to install the correct firmware.download: https://rec-bms-na.com/product-manuals/#7-8-wpfd-rec-active-bms from the readme file:2...
Hello John, Did you try to set in task, "7" on, for the charge bus. Load bus, I expect don't switch off at that temperature. It don't solve all your question, but the system will wor...
@John a probably solution is to use output: relay1 and opto2. Under task you can make different settings. See screenshot from task menu.
@Ryan I installed many V1 board. Nothing changed on pin layout with newer versions. Did you checked that your harness is a Ntype harness? If you have a Nharness and your test light is between the...
You can repeat this test, with testlight connected to blue and negative. This 2 test will show or you use the correct cable harness. Take also a ohm reading from, Brush 1, to negative, positive,...
You can test the field output with by connecting a testlight. Disconnect the blue from alternator, and connect a light to this blue wire. Other side testligt to positive( with N wiring harness) ...
Sometimes it is quicker to install one new wire from the key, instead off finding the correct wire in a cable loom. I don't prefer the extra relay, only when there is no other solution.
Is your alternator P or N? Knowing this, I can tell what to test. Also posting some pictures from your wiring can be helpfull to give advice.
Yes you can. But what is the problem ? Since 2.9 and the user programmable of CVLC , it is much better to make a nice "float" setting. (Stop charging)
@Bill Before a full charge SOC reading is not correct. When batterries are full, BMS will reset to 100%. Which charge voltage you like to apply to your batterries? Which "float" voltage? W...
@Ben @Bill good that it works. But looks like strange settings you made. Not sure or it is easy for you to do a test, or the "setcoil +". Or the "setcoil-" is the one that gives the trigger signa...
@Bill I know this switch, but have a look at the ml7713!!!
Hello Bill, System design is a choice from components. You didnt mention which ML relay you use. Looks like the ML 7700. I didnt install this with the REC prechargeV3. But install them with...
Does soemone has a working setup with the REC2Q BMS and the WS500? Can you share your settings? I dont get the communication established with the rec 2Q BMS.First time I installed this BM...
@Trond just a quick note, from thinks that come up my mind, without looking into detail. What is the voltage on back off alternator? I think, the voltage at the red wire, alternator...
You ahve the correct understanding. If you like 5% hysteresis, (restart at 95% SOC) you program 0.05. The standard, out off the box setting is 5%. You are right, if I share settings, it is bette...
@Ben@JamieAs I almost can not believe that the problem is in the WS00, can you clarify some off your wiring. Where is the big alternator negative cable connected, the negative cable that g...
@Jamie If you see 75 field drive, the alternator should produce amp. Why your alternator don't produce amps is strange. I don't see the logic why it starts produce amps after...
@Jamie some settings are not on the main settings page in the WIFI. They are not often changed. This settings you can do with, manual programming, under settings tab.
@Jamie Some extra info about your latest logfiles.In the logfile you AST. The values after AST are explained in the WS500 documentation. Values that I see, and important for you at the m...
@Jamie All settings are described in the manual.Although I didn't check the latest manual.I agree that understanding the product, needs some time to study the parameters you can make.The flo...
I checked above and dont see the suggested setting. Maybe the post is deleted by mistake. try these settings. BVOL? balance END V 3.52BMIN? balance START V 3.45RAZL? MAX allow...
Hello Jamie,. I check your VRM. CVL is limiting the output from the WS500 at 13.4V. I have posted suggested settings for you. After posting I recognised that there was an error in mine calc...
@Jamie Low output, you made setting that field goes to max 75%. Probably you have select small alternator mode. This reduce the Max amps. If you see field 100%, alternator produce the Max ...
Hello Jamie, New settings is better for batteries I think, not many manufacturers ask for a continuous float voltage from 13.9V. But your Multi is over shooting the "goal" voltage CVL, that the R...
@Ben Another strange event. System is in float 13.9( your old settings) See CVL. CVL stays constant 13.9. Then Multi start giving fluctuating voltages. All related to ...
@Jamie on the mainscreen GX, you need to see external control at the multi icon. Checking your VRM, there is charge current, when the cell voltage get higher. (On your posted VRM widget, t...
@Jamie limit amps suggest to make 200amps. Looking in more detail to your VRM post from above, I see something strange. At 5septeber around 23:00h, I see voltage rising, but no charging a...
Good that it is solved. Maybe in my earlier post ""copy"" the files was not clear enough.
Under dvcc, limit charge current, and limit voltage need to be on. Make a setting, just higher as the BMS "goal"(CVL CCL). The GX will take the lowest from, manual setting, or from BMS....
Good that you have thing working, nice feedback reports I dont know exactly why you had the zero amps charging.I dont see any relation with frimware update. Not any update that could have solve t...
In VRM, you can also add a widget that show CCL and CVL, can you post them here, from the same time line as above screenshots, VRM? Also post the widget from VRM, cell minV and cell maxV.&...
Only a short answer, no more time at the moment. Having high voltage alarms after 18 months, I see that more times. Before the cells where nice in balance and there will be no al...
