Error REM550 TDX SP

[FJC10]

Hello everybody!

Today I connected the lifepo4 battery to my TDX SP and when I turn on the remote no image appears on the screen. It only flashes red that light that you see in the video, what can this be due to? The battery gives me 26,6 volts, so it can't be low battery. In the manual of the Invacare REM 550 remote control there is no mention of that red blinking light, what does that light indicate?

Thanks in advance.

Regards.

Anything from 22 to 32V doesent give any error but might give a high or low battery warning on screen, so its not related to battery. But no idea what it is.

what does that light indicate?

I am guessing that it might be a visual for the R.H. turn indicator.

Well, I don't know what to do. It unbelievable that the manual for the remote control does not say what that flashing red light means.

What is the R.H. turn indicator and how can I repair it?

[woodygb]

Sorry ...NO idea what the problem is or how to repair it..

Have you swapped a module?
I suspect if not then its a faulty module. Or a bad bus cable or connection on one. Or corrupt settings in one of the modules.

No, I don't have turn signals on my chair.

No, I have not changed any modules. Maybe it could be some bad cable connection, when I put the battery in, it fits very tightly into the hole, maybe if I pulled the battery cable too much it disconnected a little further back in the chair. I also added a battery cable extension, because it was the only way to be able to connect that battery in that small hole, but I do not think that adding 50 cm of battery cable will affect anything to its operation, it is a cable with a large section AWG 4 or 3, copper, even somewhat thicker than the one that came with the chair. Y 4 conectores anderson.

When connecting the anderson connector maybe my brother did it several times and not connecting first the negative and then the positive as indicated in the manual

It is impossible to connect one cable before another with an anderson connector. could this have affected any component? I don't think so, but I don't know...

Btw, is there any reset button on the chair? Maybe because of those bad connections is the startup wrong and needs a reset.

[Burgerman]

Is it possible he connected the battery up as a 12V system?
I mean did it work before?

Non of the things you mention would cause any issues. And no it makes no different which pos or neg you connect first.

Unless he connected the battery backwards, at some point then it could/would damage something in a serious way...

So is this out of the blue? Ir is this now when you connect up a battey for the first time?

Checking the voltage at the joysticks 3 pin charging port will tell us if the battery is connected as 12v.

Yes, it worked before, I connected 8 cells LifePo4 Headway 12ah and the chair started perfectly and even moved, but obviously if you did not demand speed or weight, to move it at low speed it worked perfectly. But right now I don't have that battery mounted and I don't have the right cable to connect it to the chair, I would have to mount again the 8 cells and make a cable... and I don't think it would do much good, because the 108ah 72 cells headway battery that I have made brings 26,6v, measured in the charging cable of the battery and in the charging connector of the chair controller.

26,60v, same as on the battery lifepo4 charging cable

Tomorrow I will upload photos, but you will see not much, because everything is covered, I will look for photos of before covering everything

I don't think the battery has anything wrong with it that would affect the chair, it gives 26.6v at both the chair's control controller and the charging cable and the BatteryGO also indicates acceptable numbers.

I don't know what to do... Maybe contact Invacare and see if they can tell me what that red light flashing corresponds to...

Have you checked the bus cables and their connectors? To me that seems more likely than a battery cable problem.

[Burgerman]

I agree.

Have you swapped a module?
I suspect if not then its a faulty module. Or a bad bus cable or connection on one. Or corrupt settings in one of the modules.

No, I have not touched anything in the modules or added or removed anything. I don't even know where it is done. But reading in service manual, I see that all that is in the rear part:



I will try tomorrow open that part and check everything there.... For all these things I need help and that's why it takes me so long sometimes to do things, because those who can help me in these things are not every day available for help me.

From the battery I don't think it is, I would say it is impossible. It is very well assembled, with the cables all separated and secured by polycarbonate, well soldered and delivers 26,6v. Charging/discharging and balancing without problems with the PL8....

[Burgerman]

Something has failed with a module probably. The reason I have 3 complete spare sets of R-Net systems, seating, power and joystick modules, cables etc, is because I have several R-Net chairs.

If something like this happens I can just swap cables, swap modules, one at a time until it works. So I know what part is bad. So obviously now nothing will ever go wrong!

[LROBBINS]

Another possibility is that a "lock" was inadvertently enabled. Some controllers, by moving joystick and/or buttons in a particular way, can lock the system (mostly to protect from curious little fingers). Some have magnetic keys. If you have a manual for your controller do take a look for that.

[Burgerman]

I think that you would get a locked screen, not blank though.

A very strange thing happened. Reading the manual, I saw the locking thing that LROBBINS mentioned, and I went to the chair and pressed the keys indicated to unlock and.... the screen turned on! But it gave error 5, which corresponds to the clutch of the motors and as I had them unclutched, I thought that everything was ok, and I did not try to engage and see if it worked... and I turned off the chair. Today that I had help I clutched the motors and tried to turn it on again and again blocked, screen black + red light, I pressed the key combination to unlock, and it did not work. I tried several times and finally the screen turned on again, but now it gave another error, error 1, which according to the manual corresponds to a "defective module" and recommends me to disconnect the batteries and call the technical service...

What can I do with these new symptoms, open the back and disconnect/connect everything? What module do you think may be failing? The seat has electronic backrest adjustment and seat height up/down 30 cm, no intermittent lights or anything special like

[Burgerman]

which corresponds to the clutch of the motors and as I had them unclutched,

Theres no clutch. Theres a lever that on SOME chairs takes it out of drive (a gear)?

Theres are 3 modules. 4 if you have an extra one like a gyro or a attendant control.

The errors can be a MODULE (joystick, power module, seating module) or can be a BUS CABLE.

You must swap one at a time until you find the problem. Its not "locked" because that would still turn on and display a locked symbol. Its a fault.

Well, today I got help from someone, and we disassembled the back and front, where the modules are, there is also a module at the front, where the footrests. We have been connecting, disconnecting each of them and nothing. We have not been able to get it to work without the controller showing the blinking red light and until I press the horn button, it does not turn on the screen and when it does, it always shows two error codes:

Error 2 (but only for one second) Seat not at ride height.

Error 1 Module faulty

What do I do now? We don't know what else to do.

Error 2, only appears when switched on and then changes to error 1. Maybe it is a faulty sensor that indicates the seat height incorrectly? Is there a sensor that indicates the seat height? Apparently the seat is all the way down.

If I knew what voltage the seat actuator motor has, we maybe put it in to raise/lower it without needing the module, can we do that like this? What voltage does the lift actuator have?

[Burgerman]

Put the lot on the bench and test every cable or odule one at a time until you figure out whats broke.

You should only need a joystick, a power module to test the basics with 1 bus cable.

Ok, I will try to find the error by disassembling everything and testing with tester on the bench.

And, where can I buy a complete spare sets of R-Net systems, seating, power and joystick modules, bus cables, etc?

[daveonwheels]

ebay usually

Read carefully!
I bought new, or stripped from new chairs, or factory pgdt refurb brown box, THREE complete sets of R-Net top of range 120A, CJSM2 joysticks, 6 channel seating/lighting modules, looms, bus cables, and a few spare odments too. Enough for 3 complete rehab full house powerchairs for under 1k.
