Hi,
I have spent a day to try and get the proper throttle control from the CA V3 working, but my ignorance and lack of understanding even amazes me. I have read and re-read the CaV3_UUG_B22_20130315_1650.pdf, including Appendix A.
My setup is a Crystalyte HS3548, Crystalyte C3640-CL, Cycle Analyst V3 running at 36V.
I have the CA V3 directly connected to the Crystalyte controller, even though the CA V3 was originally bought as stand-alone. I have omitted the external shunt and programmed the real resistance.
My understanding is that the Crystalyte controller's throttle is only controlled by the 3 pin throttle controller input cable. If I plug a throttle into this cable it controls the motor works as expected. The CA V3 registers information from the controller.
The ThO (Green) on the CA-DP Plug normally plugs into the controller's plug as pin 6. With the CA V3 connected and plugging a throttle into the CA V3 throttel input produces no motion in the HS3548 motor even though the CA V3 shows changes in output voltage which I have verified with a multimeter. The controller identifies this pin 6 as Throttle Override. I am not sure of its purpose.
If I re-route the green throttle wire at the controller connector into the corresponding throttle cable pin and plug the throttle directly into the CA V3, I get changing throttle out voltage on the CA V3 but not movement of the engine.
If I run a throttle cable to the throttle input and but re-route the throttle signal wire via the CA V3 throttle input and re-route the green ThO wire at the controller end into the controller's throttle connector, I still get no movement - even though throttle output voltage changes.
I have tested the circuits and all appears fine.
What am I missing? What am I doing wrong?
The throttle input plug on the controller consists of 5 V +ve, Gnd, ThO (signal). Shouldn't the green ThO at the controller end be enough to give throttle control.
Thanks,
Peter
