Default Re: Roll away braking

Sorry to keep two threads going, but it is kind of related....

Joesam, if You want to disable the Regen that limits your speed, but maintain the Regen and Dynamic brake brake on pedal up:

Use a SPDT 48v relay, wire the green wire of the Speed sensor thru the Normally Closed contacts and the Relay coil to the Pedal limit Switch.

That way the speed sensor pulses are disabled when the pedal is pressed and on the rest of the time.

Does anyone know if the magnet on the regen 2 motor is 4 pole or 2 pole. If mine is 4 pole I should be able to grind off part of it and not have to use a seat switch to keep the roll away braking. The max speed of the cart is less than max of pedal up braking if I can use a 2 pole magnet. This would save some wiring.

O.M.G - That is absolutely BRILLIANT, Sergio! Why the heck didn't I think of that? Talk about the Forest and the trees!

I assume I can pick up the required volts for the relay between the Dynamic Braking solenoid post (my manual says its Brown) and the main positive. That's the test points for the Dynamic Braking solenoid - which only shows 48v in forward/key on/pedal depressed.

Or should I look elsewhere (eg. tap wires at the controller)?

Mrgolf - you should give some consideration to what I'm gonna do come springtime.....read Sergio's note to me. It solves your Plum quick extra speed issue, and gives you gentle braking on extended downhill coasting with a pedal lift.

But then you would want your Dynamic braking re-installed, or else you'll leave a nose-print on your windshield. Its really the best of both worlds. I feel dumb for not thinking of it.

I'd be nervous about hacking the magnet - because who knows where you'd get a replacement anymore.

I have another magnet, I'm not sure how to tell how many poles it has. It is about the same size. I'm going to play with it.

Good for you! Well then I would think you can use a small (maybe 1/4" dia) "wand magnet" to find the poles and determine what/where to cut / grind.

That is it, You just need a small magnet, put a marking in the sensor magnet the first time the small magnet gets attracted to the wheel, then without changing the orientation of the small magnet You are holding, move it around the perimeter of the sensor magnet and see how many times it gets attracted and repelled.

You should have even number of North/South poles in the sensor magnet. The new carts have 8 poles (4-North and 4-South).

You need to leave at least 2 poles (1 north and 1 south) so the Hal effect switch can work correctly, the fewer You leave the less the Regen break effect will be.

Joesam, You would need to wire the solenoid coil from Pack Negative/B- to the Pedal switch itself, Green/White wire. The other solenoids are powered by the controller itself and will not work for disabling the speed sensor.

I am attaching a good quality wiring diagram for the Regen 1.

Thanks I have that diagram (the whole manual in fact). OK - come spring I'll find a convenient spot to attach to the grn/wht from the POT Box & pack neg. Think I'll get a relay socket and do the job right with a decent clip/holder to frame or cross member and some form of water-protection. I've used relays fairly frequently for other (non-cart) applications - this is such a cool solution.

Thanks.

I like those charger relay type with quick connect terminals and flange for mounting so You don't need a socket, unfortunately, the SPDT are hard to find in stock: T9AP5D52-48 (both Mouser and Digikey are out of them)

Is it just me, or does that look like the CC charger relay??? Is the charger relay N/O or N/C? No wait - its missing a pin. No worries, I've got the rest of winter to find one....that one does look nice & industrial.
