  • Glad you got the lithium batteries sorted Triumph. About keeping the wheels low, this is something Pat the inventor also recommends for stability. We keep our just scrubbing the ground.

    To see if the clamshell is closed, you may want to try to place a mirror in front or behind you. The weight of you not in the chair will make a difference when raising and lowering.

    • Yes, tried a full length mirror and couldn't see too well. Will try hand held mirror. I'm still getting used to this, but it sure is a good way to insure your tires are scrubbing the floor!
      Also heard a loud beep from my zx1 the other day - the lithium batteries gave me a warning that they were shutting off. I had been visiting and had not turned off the power and after a few minutes it was done for me! This feature was not on my original batteries.

      • Recently had to adjust left wheelchair wheel as it was practically sitting on floor while in zx1 instead of 'scrubbing' - there was a lot of play in the wheel and we had to work on nut on axle bar of wheelchair - found both sides very loose.

        For more info see my post under Equipment.

        • I put a bit of locktite on the wheel axles to help keep the nuts tighter. They do come loose rom time to time.

            just spin the wheels when you are locked and raised at the top and lower yourself down, once they stop spinning you know you're all set...

            • Thanks for suggestions!! Also plan to check air in zx1 tires, although I don't know if that's a factor.

              • The actuator on the ZX1 is 12 VDC but the batteries connected in series mean the power module is 24 VDC. Excuse my ignorance but isn't this going to cause a problem?


                Cheers

                  it is i believe they should be 40psi the psi limit is on the inside of the tire i think

                  • I'm a new TX-1 Lithium user (as of last Friday) and still working on some bugs like old program still in controller, so no crawl mode when BMS kicks in. Just stops and no more go till I connected charger or briefly disconnected battery terminal to reboot. Dealer and Spinergy are sorting that out - I hope. I bought the knobby tires too, so grass is my friend, not enemy now. Just wanted to introduce myself to the forum.

                    I'm a complete C5-C6 quad since 1977, this will be my first powered chair although I've designed them myself previously. Drive an Audi A3 hatch after many Saab 900 cars, but transfers are getting harder as I get older.

                    I've learnt a lot from this forum and will have more to say as appropriate.

                      Hi takenaback,
                      The output for the linear actuator, like the lights in the dual output VR2 model gives a 12V output, if my memory serves me correctly, in the same way that the brake can be 12V/24V rated. It depends upon what is ordered in the controller by the OEM. Worth checking with a Voltmeter though, before playing. Linear drive needs end stops too, so not just any cheap on will do. For details of the VR2 Controller, see http://sunrise.pgdrivestechnology.co...SK77898-03.pdf This technical document also explains the various Setting Parameters for your speed, braking, acceleration and deceleration in forward, revers or turning

                      Just to introduce myself, I'm a recent ZX-1 owner - as of last Friday - and been busy collecting ZX-1 stuff. C5-C6 quad since 1977, living in SE Australia.

                      I have the latest manual released from Spynergy, because the one supplied with machine was 2013 and not relevant to Lithium options, but this is.

                      Colin.

                        • When my lithium batteries (aftermarket) were installed by my DME fellow, there was an "interface" thingy about the size of a cigarette package included in the shipment that had to be connected to the batteries. I was told it was necessary for the new lithium batteries to make the joystick controller work...I think. I'm able to use the same charger that came with my ZX1 two years ago.

                          • That interface thingy box is the external BMS (battery management system) that protects the Lithium batteries from over charging, over discharging, and excess current. You also need your controller program updated with new software to deal with the MBS interface box, adjust the charge lights voltages, and other things. I hope your DME updated the software at the same time by plugging in a controller with a memory stick inserted. If you get abrupt shut-downs from low battery without warning beeps, or from high, discharge, you can reboot by detaching one battery terminal to reboot then detach. This would be because software has not been updated.

                            • I have a collection of up-to-date Manuals now, which are much better (but could still be improved - I've already edited, slightly, my version). Latest Operator's Manual (which covers Lithium batteries too) is Z100080 REV 6, March 1, 2015.

                              Spynergy sent this (through my dealer), which is positive - "The Field Service Manual [will] be posted on our Website... We will make it a PDF that is downloadable along with our Operators Manual. We were planning on doing this with our new Website that should go live in about two weeks. We will go ahead and post it on our current website so that it is out there!”

                              • Hey Colin, Welcome to the forum. I'm really honored that you are now a ZX-1 owner! Your Kangan Roo chair was a big inspiration in my inventing the ZX-1 to begin with.
