Project 2000 Bed - Struggling Going up!

[elwyn horton]

We have a Project 2000 in our van, which goes up and down, on belts.
Just been away for a few days and the bed is struggling to go up, it does go up, but very slowly and the lights flicker and the Trauma boiler shuts off, due to no 12v supply.
The 100amp AGM battery is just over 12 months old.
I have a plug in volt meter, the bed problem is at night, when lights are on and battery is showing about 13v.
Does any one have any ideas, is the problem the bed, the battery etc.
Any advice is appreciated.
Thanks.

If you search on Project 2000 on this forum there are quite a few posts about issues & how to overcome them if the bed gets stuck!

Are you plugged in to EHU?

Not an expert, but to me it’s likely to be either:

• The motor wants more current than the cables can handle- (shown by a low voltage, anywhere on the house system),
  • possibly due to a mechanical jam in the slides or motor:
    • can you lift the bed the bed by hand, is it free to move. Does it come down freely?
    • If you’ve taken the weight off the motor is it still slow? – motor problem
• The cables have an additional resistance, due to a loose joint, corrosion or fraying etc, before the supply to the Truma
  (when the lift motor is on, if there low voltage at the motor, but still high voltage at the battery?)
• The battery can’t provide the current needed: Is it nearly flat?
  • Is the charging working?, (voltage at the battery when charging should be >13.5v?)
  • Is it solar charging only? (Last month it would have got very little!)
  • Is the battery goosed from being run too low, or stored when flat?
    • When the lift motor is on, is there low voltage ~12v at the battery?.
    • Does the motor behave with different battery, jump starting style?

I’d check all the cable joints on the charging circuit, and up to the fusebox

Thanks, we use on EHU.
I forgot 6 years ago when we bought the van, every time the bed was raised it blew the 15amp fuse. On our first trip to Southport, I was stuck and ran out of fuses. Rang the dealer next morning and he suggested increasing fuse to 20amp. It has not blown another fuse.
But would this indicate that the motor is pulling a lot of current, if it is using between 15 and 20 amps?
It has always gone down without any problems.
I know nothing about electrics, don’t want to mess with wiring.
So I will start with winding belts, see if they are aligning properly.
Another thought is if the van was not level, would gravity pull the bed out of level, after a day or so being used and mess up the belts?

Yes always on hook up.

Thanks, sounds like Project 2000 are not the best manufacturer.

Still a possibility of bad cables... no different on EHU. Good luck!

There are slightly different Project 2000 beds mainly control panels some key some with out , probably better taking pictures so you can be help better ,
Some beds have limiters some don’t , resetting /programming is different as well ,
look on YouTube there some variations of different beds on there with fault finding problems .
If I can find them I will send a link .

There’s a few other as well
Good luck.

Some time ago I did an energy audit on our van, which is equipped with a Project 2000 bed, and I noted that it was consuming 13A when raising and is protected with a 20A fuse. Does the voltage at the battery drop below 12-13V when the bed is raising? If not, and given that this happens on EHU with a probable 10-15A charger/psu fitted, it might imply a poor connection in your DC control/fuse box. This is presuming that there is nothing wrong with the bed and that the motor is not being overloaded as a result.

Only just seen this so sorry if you've already sorted your problem. I had issues with my project 2000 bed several months back.
I managed to contact a Lippert expert and he sorted me parts and information. He was also happy for me to post his details on here: Neil Mears mob: 07506 229507 Home: 01925 640625 He's an excellent engineer and thoroughly decent gentleman. Hope this is of use.

Check that nothing is fouling the belts or rollers

 

[buzz1]

I think he may have sorted it out,
as he’s not been on here since last Friday .

We have a similar problem - the electric bed in our Pilote P696D keeps blowing a fuse, we've replace it 3 times.

I'm reading different things though - the blown fuses supplied by the dealer are 10amp, shouldn't they be 15/20?

I can't even work out which bed it is, though the control panel is a Lippert.

Does your bed have "Gas Struts" to assist, dig deep to find out, they may be loosing pressure , replace. It solved my problem.
