- Instructions on how to set up the XH-M609/HCW-M635 over-discharge protection module. There are four setting values you can change in this module using the two buttons (+ left and - right).
The first setting is to calibrate the voltage. Use a voltage meter to check the voltage is the same on the battery and module. To adjust, long-click the +left button until the LED screen flashes. Then, while the display is flashing, adjust the voltage with the two buttons (+ left and - right) to equal your battery's (voltmeter) value.
The units default on/off values are 12v (short +left click) and 2v (short -right click). This means the undervoltage value that the unit switches off the load is 12 volts. The unit switches the load on again when the voltage rises to 12 + 2 = 14 volts. To change these default values:
1. Change the undervoltage value by double-clicking the +left button until the dot (decimal point) on the LED screen flashes. Adjust up or down with the +left and -right buttons.
2. Next, change the module switch-on voltage by double-clicking the - right button. This value can be changed and is the voltage increase required for the unit to switch on the load.
Lastly, there is an adjustable time delay function whereby once the unit reaches the voltage value that switches the unit on, a delay can be set. To adjust this value, long click the -right button, then adjust that value up or down with both buttons. 0000 equals no time delay, 0005 is approximately a 30 second delay.
This is a really nice unit if you know how to use it!
I'm an old guy of 75 and still enjoy electronics. I would have battled setting this module up without your excellent and practical demo. Thanks!
THE ONLY CLEAR AND UNDERSTANDING EXPLANATION OF THE OPERATION OF THIS MODULE.
Dean Satchell - THANK YOU SO MUCH!
Thank you so much for this concise explanation. I would not have had a clue without it. As noted by someone else, the time delay on mine is in minutes. 1 to 10 minutes, or zero on "000"
Thank you for your explanation of that time delay function. The documentation found on AliExpress and elsewhere online is severely lacking. The operation of that feature was almost impossible to find using trial-and-error.
On my version the value is in minutes (000-100) where 000 is (almost) no delay, 001 is one minute delay , 002 is two minutes. Thank you once more!
Thanks!, I’ve never noticed there was a hidden setting for calibrating readout as well. Best regards.
Thanks for your comment!
Thank you so much for the simple illustration
Very clear & simple, easy to understand all the parameters - BEST
You might think 149 thumbs up isn't many, but multiply that times the HUGE amount of help this is for each of us. Thanks!
Thank you for explaining the "time delay" setting. That's what was stumping me!
Excellent practical demonstration together with a really clear explanation. Thanks
What a great tutorial. Thank you very much for sharing your knowledge :)
Thank you for this upload. It helped me out a lot. Best video I have found on this board.
ЕДИНСТВЕННОЕ ВНЯТНОЕ И ПОНЯТНОЕ ОБЪЯСНЕНИЕ РАБОТЫ ДАННОГО МОДУЛЯ.
Dean Satchell - БОЛЬШАЯ БЛАГОДАРНОСТЬ ТЕБЕ!
Hi, very clearly described
Thanks to you, I finally have this very handy device working 👍⚡️
Excellent. The instructions that came with it are useless. Thank you.
Thank you. you have just saved me. By the way, that time delay function: every 1 unit increase means 1 minute delay on my module.
Thank you very much! Super clear instructions. Plus, your English is so easy to understand compared to other videos on this module that are supposedly in "English!" :)
Thank you for this Video, i ordered mine and there was no manual. You helped a lot
Mate, if I'd seen your video 2 months ago it would have avoided me soooo many headaches! Good work and thanks a lot for this content.
Thanks and no worries, I did this because I was experiencing those same headaches!
I agree, this was the best video I have found on this board.
WOW... Try getting that information in a Chinese instruction manual!
Well Done!
Thanks, took a while to figure out...😄
Thank you for doing this it was very helpful.
Dean this was *exactly* the video I needed, thanks so much for making such a clear one!
Out of interest how did you find out the spec in the first place? I couldn't find a suitable manual anywhere.
thank you brother very informative. from Sri Lanka 🇱🇰
Welcome!
Great tutorial
Thank you.It helped me to set up mine connected to litiuim batteries as low voltage protection.
You're welcome, glad it helped.
You're welcome, glad it helped.
On yeah mate, thanks a lot lovely clear explanation.
You're welcome
Thanks a lot for this video! Exactly what I was looking for)
Very clear explanation. Thank you.
Someone else commented on another video, to tie the output + to the input + with a momentary button. This latches the unit on, but when the power drops below minimum, the whole unit turns off. Avoids the slight 60mah draw this unit makes.
@my_channel_44 I'd love to know more about this! Can you please provide more detail or the source of this information?
Thank You, Thank You, Thank You From Goderich, Ontario, Canada Liked and subscribed
You're welcome. These modules can be very frustrating when there are no instructions...
Good info.
Thank you!
Thanks my man,very helpful
I have this module. It seems good but a coil and a capacitor are very hot.
와씨 영상 감사합니다. 덕분에 해결됐어요.
Hi sir,
Thank you for this video, I would like to know
If I have solar panels 400w 24v ,500f 16v capacitor and I want set the buck converter at 14volts how much the value of amps should I set on the back converter to charge the capacitor without damaging on the capacitor ?
Hi its posdible to calibrate the voltage
cant find this info anywhere, what is the maximum current this can switch?
it is not XH-m609 as described in title but HCW-M635. they look the same with one slight difference: XH-M609 does not have the calibration feature, like the model from this clip (verified on mine XH m609)
Would be good if anybody else could verify this as my understanding is these are the same modules. Indeed the module is often sold as XH-M609/HCW-M635. I have bought this module from multiple sources as XH-M609 and they all have the same calibration feature.
@@deansatchell5481 i already verified this "on my own skin". i have this module M609 and it does not have the calibration feature.
Yea.. the M609 version doesn't have calibration function. Meanwhile M635 is pretty rare.
Hey there. I also have a xh-m609 without the additional Calibration and TimeOut Features.
Best
Yeah thanks for this - thought I was going a bit nuts trying to long press to calibrate, luckily mine didn't seem to need any calibration - I can live with .1 of a volt, which is about the normal variance of all different multimeters anways.
Thanks! What is the lowest cut-off voltage?
Ok the title of the video is missleading. The XH-M609 does not have the function to calibrate the unit.The + button only ajust the low voltage cutoff. It makes the full screen flash and you ajust the voltage to what you need. It can't make only the "doth" flash to ajust the voltage like the one in this video.
Yeah, agree. I also have the HX-M609 and it behaves differently than in the video. (same as others here in the comments). Reccomend to take that out of the title. Otherwise, thank you for the video- helpful. I wound up through trial and error figuring out the M609.
yeah shame both units are sold with either name.
nope, you're wrong dude. i have this module and it has exactly same 4 settings as mentioned in this video. i connected an adjustable power supply to input and set it to 9v, this module showed then 9v too. but when i long press + button and set it to 12v for example, this module assumed the input is 12v and when i increase the input voltage to 12v by my power supply, the input voltage increased simultaneously to 15v. this "calibrate" setting can be used to be sure that module is showing the correct voltage compared to a reliable voltmeter.
Regarding the time delay, my boards set to 001 gave me almost exactly 60 sec. Looks like its calibrated to display minutes. Any one else ?
Yes, mine as well. 000 is (almost) no delay, 001 is one minute, 002 is two minutes. Value range is 000-100.
I too appreciate your instructive video. Getting a manual for this device is hopeless without your help. Chinese English is not anyone's specialty.
I am left with one question though, is there a way to turn the display off so you don't use precious energy in standby mode?
I found one that is preset to cut off at 10VDC and back on at 10.7VDC, it has no display or setting switches, just 2 wires in from power source and 2 wires out to the load. (10 AMPS)
Part info= CZH-LABS Electronics-Salon Low Voltage Disconnect Module. It's bit expensive though $15
Yes. Set the delay to zero. Wire your power (-) neg to the IN, but wire the power (+) to the OUT. Use a momentary push-button switch to connect the (+) IN to the (+) OUT.
Press the momentary switch and the unit will turn on, and the relay will latch. When voltage input drops below the threshold, the entire unit will turn off completely.
Someone came up with this solution in the comments section of another video on this board.
Hi Dean. I just bought 2 of these and am unable to cal the input level. I am also told that this is not a feature of this LVD. I am confused to say the least. Double press on the + does nothing, similarly the -. Have you heard of/seen different variants of this same device? Thanks for the tute.
Hi Colin, it is unfortunate that there seem to be different versions of the same module on the Chinese market. If you require that feature my advice is to try a different supplier, buy one, then test it.
Very nice simple explanation. Do you know what the current rating is?
they are like 20A for 14v
👍
Thanks.
No worries Bob, glad this was useful.
Hi, can i use this module to my portable solar generator? If i charge it by solar panel, when the sun goes behind the clouds the charging stops and the generator beeps on and on. The problem is it doesn't automatically restart the charging when the sun is out. Will this module solve my problem?
something wrong with your unit
Do you have the low voltage set point to low ? 5 months on did you get it sorted ?
My XH-M609 looses the settings after I disconnect the power. Is there a solution to keep the settings?
I'm not sure, my XH-M609 doesn't lose its settings after 1 day.
@alexandru Mines does the same thing. Did you work out how to stop it losing its settings?
Same as that, I bought 2 from amazon and the both revert 12V cut off and 2V differential. this is driving me mad.
Can i use this module for 48v Battery pack,can settings go up for 48v cutoff? Or is limited for maximum 36v?
The specifications I've seen are for 12-36v, sorry... I'm not sure.
@@deansatchell5481 thank you for answer,
i thougt that you try to set higher value to see how high module can operate.
Could do that with a voltage divider on the input. Would be better to try and find a module that will handle 48V.

Thats the problem buying stuff from china, the quality is ok but correspondence is zero. If they want to sell outside of China they need to go to the effort of getting a translator to make things clear. You would get better info from Manuel from Faulty Towers. Appreciate your post.
When low voltage will the display off ? or is it keep on ? How much ampere this unit consume when low voltage cut off ? thanks in advance
