Topic: power management system pms 3v

Posted By: pat534
Subject: power management system pms 3v
Date Posted: 09/4/2010 at 6:26pm

I have a PMS 3V power management system in my campervan.I do not have any instructions in how to use it.

can anyone tell me if the charger supply switch has to be on for my leisure battery to be charged from the engine battery or is this just for when the van is connected to mains electricity.

There is also another switch called battery selector. It has 3 options car - off -van.I have been using it on van when on site without electricity and then putting it on car when driving.

My van is a nu-venture surf.

Can't help you with the PMS 3V power management system but regards the switch, when on EHU if you select car it will charge your car (motorhome) battery, when on van it will charge your leisure battery, when not on EHU use the van option or you will end up with a flat battery on the motorhome

thanks Ken. It was what I thought but just needed a second opinion.

Sorry to jump onto this thread - but does anyone know where I may be able to download a copy of the fitting instructions for one of these units. I took mine out of an old van and whilst I can see everything clearly labelled on the back, mine also had a 6 pin relay feeding into it. Does it need a relay or can it just be wired as per the details on the back of the unit???

Sorry,just a quick point about the selector switch(car-off-van)...

On our previous MH(a Compass),that switch just selected which battery you were drawing off and didn't select which one was being charged!

It may very well be a different set up on your van but it may be worth just emailing Nu-Venture,to check....

Yeah, we use the switch to select which battery to draw off but I have checked with a meter and mine also charges both batteries when on EHU

That's a far better set up than was on our previous Mh.. image: - http://www.ukcampsite.co.uk/chatter/forum_images/smiley20.gif" width=23 >

Our leisure battery was only charged via the hook-up(..not that it ever became an issue,to be honest).

Hi, I have the instructions for a PMS3V, 3 pages, let me have your e-mail address and I'll scan it and send it to you.  Cheers

Thanks for the kind offer - in the end I managed to speak to someone at Bonus Plugin Systems who posted out the fitting instructions - great service from them.

I have just emailed Nu Venture to get clarification for my van.

Now I have the instructions here is what it says about Battery Selector Switch

VAN position : When in this position dc power is available from the caravan/motorlome battery to power all 12 volt electric circuits. If the charger is switched on, the battery will be charged up via the charger/transformer unit.

OFF position : With the charger/power supply off, this position isolates all DC power in the caravan/motor-home. NOTE : The switch should be placed in this position when the caravan/motorhome is being driven between locations.

CAR position : The switch can be placed in this position should the caravan/motor-home battery become discharged and no mains power is available. Power will then be drawn from the car/main battery to power all 12 volt electric circuits.

I believe the reason for going to OFF whilst travelling is to protect the charging unit.

This thats basically what has been said in this thread about the various switch positions. For me I was getting confused a little with the extra relay that came off the old van, but I now see that you still need to charge the leisure battery on it's own whilst driving so its all clear now to me.

Hi

 nu Venture say my system is old and they do not use it anymore.Gbrockley please could you send me the instructions as well.My email address is Anhegraig at hotmail.co.uk .

Richard I have read your instuctions. Thanks.

So if I am on the car setting when driving around will this charge my leisure battery.If not then how do I charge the battery when not connecting to EHU.

I am off to the Hebrides at the end of May and will not have EHU while there.

No when driving around the switch should be in the off position. I was supplied a wiring diagram from Bonus and it shows that to charge your leisure battery when driving around you need to have a relay fitted which will provide the charge for that battery. It also shows a second relay to charge the fridge.

Thats what confused me I have to admit - I had kind of thought the PMS box handled all this but in fact you need to fit the basic split charge relay system regardless and that what the PMS box does is handle your electricial requirements when stopped - like ehu, 24v and 12v feeds.

I bought a dual split charge relay from Halfords and will fit that to control the fridge whist on the move and the charge to the leisure battery.

Hope that helps - get me know if your still confused :)

Hi Ricky, I installed the PMS3V unit in my campervan and I have scanned the instructions and wiring diagrams in a "Word" document. Let me have your email address and I'll send it to you.  Cheers,  Gordon

Hi all,

This message for Gordon Brockley

I too have a PMS3V system fitted to a newly purchased Bongo Campervan which had its first outing to Scotland last week. I thought I understood the workings of the unit,but have no instructions and can't power the fridge other than when driving, or the 2 wall sockets for accessories.I would be grateful if you could email a copy of the manual if possible (looks like a business oportunity for someone opening up here!!!)

Iain

Hi Gordon, many thanks for the offer of PMS 3V instruction manual. My email address is rickycornwall at gmail.com (the at sign should not be in letters)
thankyou again. I have just managed to drain both batteries in my van...so any help will be much appreciated.

Sorry but this relates to the switch, you could use a CSB-2 "battery Master" which would automatically switch the charging of the cab or leisure battery.

When the leisure battery voltage exceeds 13.6V it starts to charge the cab abttery with 0.1 to 4A dependent upon the state of the batteries. Once the leisure battery gets down to 12.5V the cab battery is diactivated so as not to crash the battery. Very simple to fir, usually these are in the region of £70 but I have a brand new one for £ 40 that would come with full 1 year warranty if interested.

If this is of interest please just say

Iain, you can use your fridge when you are hooked up to mains supply 240v, engine off. You can only use the 2 x 13 amp sockets when you are on mains hook-up.

Hi Guys, New to this forum and new to campervanning. Just bought a Nissan ELgrand. The leisure battery was totally dead dead dead. Bought a new one. Now, one week later without using it, it too is dead. The van has a PMS3 unit. I have now downloaded the instruction manual. It says under the Polarity Indicator " .... will illuminate if the mains input to the unit has become reversed and will require correction".  Well when I hook the van up to the house electrics the light does indeed illuminate. Is this just a case of reversing the L & N from the house (which is correctly wired at the moment) and could this be the cause of the battery being drained. Thanks Guys,  John
