aquired a dirst cheap quantum 6000z power chair

[firehopper]

It had dead batteries and no charger, got new batteries and a charger, but now it reports error 107 charger inhibit when I try and make it move, all aux motors work, chair tilts seat back moves and leg rests move, but chair does not, anyone able to help me figure out what I need to do to make it work again?

[Burgerman]

Did it have an on board charger? Has someone messed about in programming? Inhibits can be turned off or inverted.

[firehopper]

not that I can tell, it was at a pawn shop, and it was originally listed as $400, I got it for $50 cause they lost the accessories it came with, the batteries were 5 volts each, and I couldnt recharge them cause they went bad, so I bought new ones and a pride 24v 5 amp charger, now I'd like to get it working again, but I dont have a programmer yet. and the software wont install for me, so I could use some help figuring out what to do.. I tried running it without the AAM and attendant joystick, but it still reports the charger inhibit error. I'm wondering if it is something wrong with the main module. (they arent too expensive to get)

EDIT


Hmmmmm ...wasn't this error reported on the Junkie Forum.... I think the fix involves disconnecting and reconnecting some plugs.

[firehopper]

I think I know what wire they are talking about, I can try that too..

[firehopper]

well that didnt help still error 107

[woodygb]

The inhibit is usually a connection between GND/Battery negative and the center pin of the charger socket.

The inhibit link is inside the charge plug....see pic.... BUT any similar connection somewhere in the wiring could also cause this fault.



NOTE:- Pin 3 will be connected to the main controller via the wiring.

[Burgerman]

And the inhibit for either on board or external charge is reversed. In programming.

and on my chair the charge plug is part of the qlogic 2 controller so I would have to disassemble that I guess.

[woodygb]

We have a difference in what we name the various items.

Joystick pod....where the charger plugs in.

And

Controller :-The black box that usually sits under/behind the chair seat.

More often than not the wire of the charge SOCKET connects to nothing inside the pod itself ...but instead goes via the wiring loom to the main control box.

Have a look see.

[firehopper]

yup thats what I'll have to see, I havent seen a single pin diagram of the plug that the controller uses.

[LROBBINS]

The inhibit connection is normally in the PLUG on the charger lead, not in the SOCKET on the joystick pod. When there is an internal charger the inhibit connection is also internal, but is usually reversed - high to inhibit instead of ground. If the chair had an internal charger, even if it has failed or even been removed, there may still be that inhibit connection. Whether the system is "looking" for an internal or external charger is set in software.

[firehopper]

what is that thin lead on the back of the chair with that rubber plug in it, is that for a onboard charger? it came with the rubber plug in it, not sure what that does. it also had a small actuator board that wasnt hooked up to anything at all. not sure if that also has something to do with it.. part number is ctldc1493. no wires or anything just a board.. I removed it and dont see any plugs that should have plugged into it, and cant find any info on it at all.


by the way, thanks for answering all my questions woody and burgerman

I see which one I have to change, just have to wait for the proper lead

[woodygb]

I did ...yesterday ...look for an onboard charging option for the Quantum 6000Z and couldn't see one listed.

[Burgerman]

It doesent have on board charging. On that chair. But its basically a curtis instruments control system. So used on other chairs. So if someone has configured it for on board charging, and set the hi/lo inhibit then it will give an error.

[woodygb]

Perhaps try pulling the inhibit high, by connecting the positive to the inhibit via a 10k resistor.

nice find, that link shows the charger I bought, the first one there is the charger I got..

I can try, I'll have to dig through my pile of parts and find a 10K resistor.. I have some in my parts box I think

[firehopper]

here is the board that I dont know what its for. it wasnt hooked up to anything on the chair. just sitting there.

[LROBBINS]

That looks like a board that may not be part of the Curtis system but added afterwards to control one actuator (e.g. seat tilt): it has 2 relays (I assume SPDT in an H-bridge configuration) controlled by a toggle switch and something that senses when the seat is up or tilted and sends an inhibit to the chair's controller. That inhibit would almost certainly not connect to where the charger inhibit connects, but to an inhibit pin on some connector probably on the power module if there are no auxiliary modules. It is impossible to tell whether that works as inhibit = high, low or open, but if it's not connected that may be what's causing your error. This too can be corrected in software if you are not going to be using that board.

okay, well Wow, connecting it to high did the trick it moves now! thanks so much. connecting it to - makes it think a charger is connected. connecting it high and turning the chair on, and it MOVES no more error 107, so I'm gonna get a xlr connector and solder a 10K ohm resistor to inhibit and + just in case it does it again! thanks so much woody!

[woodygb]

Your welcome.

[firehopper]

is there a source for that programming xlr plug the 5 pin one? anyone managed to find any of those?

[woodygb]

Sadly not.

You could try asking a dealer for a replacement lead for a handheld programmer.

Curtis part number Cable XLR 17926304-02...I think.

[firehopper]

well the chair stopped in the middle of driving, went about 30 feet and then it stopped, and came up with the 107 charger inhibit error again, and I cant clear it anymore, the resistor doesnt help anymore.. not sure what to do now.. cept wait for the can interface and try and read the error logs an stuff..

[Burgerman]

If you disable the inhibit, or reverse its parameters in software it may be fine. Or you may need a new joystick pod...

Try a 5k resistor...

I'll do that. right now I have it sitting with the main power lead to the controll module unplugged..

[Burgerman]

If that works then the charge inhibit is configured in reverse, as it would be if you had an on board charger. Which means either:

J/S pod is faulty.
Someone has replaced the power module and it has on board charging connected previously.
Someone has been messing with the programming for reasons unknown.


In case the code triggered is incorect, test the freewheel lever. It disconnects the brake, gives a similar error. Engage and disengage many times, check microswitches. Also test any seating microswitch inhibits such as tilt... Similar error, may be misconnected to wrong inhibit.

when I operate those, it should give a error about motor brakes.. will test again. as for the seat switches. I have to go through the wiring tangle behind the seat, I have the aam loose from the seat and will try and trace wires..
