HALL Effect Throttle hookup Question

[Jeff Winder]

Hello,
I replaced the controller on my currie EZip Trailz, (Brushed Motor). The original controller was a 24v , the new one is 36v. I also upgraded the battery to 36v LiPO.
The new controller is http://www.electricscooterparts.com/hookup/SPD-36500Awiring.htm .
Can anyone tell me from the wiring diagram above if this controller can be used with a HALL effect throttle?

My Currie throttle, is a HALL effect throttle. Is this a voltage issue with the throttle as it was 24v throttle and now I'm using a 36v controller or do I have the wrong type of throttle?

Any suggestions appreciated..


Thanks,

It is probably a hall throttle, and will work with your ezip once you figure out the correct way to wire it up. What won't work is the LED battery fuel gauge because it's meant for 24v.

It should be wired up like this. If you have more than three wires, you'll have to figure out what does what.

You can do a bit more reading about throttles on my site here.

auraslip,
Than ks for the quick reply. I have tried wiring the 3 wires up as you indicated, but to no avail. I have a red, black and green on both sides of the connection, If I wire color to color no power when throttle is twisted. However if I cross the black on one side to green on the other for both, the motor fires up full speed but still no change when I twist the throttle.

I will next try a potentiometer on the controller to see if that allows speed control. Green to wiper and Red and Black on either side.
I will try a 5k pot and see what happens.....

Oh, I also took you advice on the LED battery indicators to get them to properly indicate the correct value when used with the higher voltage. I will use a pot there to tweak in the proper settings. I will then replace with a resistor of the proper value so that it indicated low power at about 32v.

Thanks Again,

With high voltage on one of those wires it is easy to blow the hall. Measure everything before hooking it up! Look for ground, +5, and high voltage. Keep that high voltage wire away from the throttle low voltage wires!

If the hall throttle is working but the controller is expecting a pot it will probably control but won't go zero or fullspeed, only giving a middle range. Of course if it supplies higher voltage to the "pot" it could be damaging to the hall.

The hall should work but if you crossed a power wire it's toast. As for the power leds, they are usless with a lipo. You will get full battery, then the next thing you will see is low or dead. Lipo's don't taper like a SLA does, they maintain most of there charge then drop real fast.

That and the battery gauge is for different voltage range, so it might not even work at all.

If I wire color to color no power when throttle is twisted. However if I cross the black on one side to green on the other for both, the motor fires up full speed but still no change when I twist the throttle.

Sounds like they are using a non-standard colorings. Pretty common. I guess I should amend the picture to show that it might not be black = ground, red = 5v, and green/blue/white = throttle signal.

Check with the wires with a multimeter. If you've connected the 5v controller line to the throttle signal line, you might of blown the hall sensor. If that's the case, I have some extra halls. I can put one in an envelope for the cost of a stamp.

OK,
Success ...... Hooked up a 50k pot, (did not have a 5k on hand), to the 3 wires on my controller, and was able to throttle my motor from 0 to full speed.

So the question I have is... Does this indicate that my controller uses a potentiometer throttle, or will a HALL effect input to the controller allow you to use a pot as well.

If I need a resistive throttle, will this one work?? http://tncscooters.com/product.php?sku=101117
The above link does not indicate Hall or Resistive, so I'm kinda lost.

Anyone know a site where I can find a split twist 'resistive' unit ???


Thanks Again,
Great site for info....

When a resistor throttle is used on a hall input, it works fine, but there is a region at both ends where no change happens. At the low end, the motor does not run for a fraction of a turn of the pot (possibly 20% of the pot rotation). At the top end the velocity does not increase in this region, also about 20% of the rotation. So the changes take place in the middle 60% of the rotation.

Hall throttles output a smaller voltage range and match this. Something like 1-4 volts instead of 0-5.

Did you ever measure the voltage coming out of the controller for the throttle? Is it 5V??

I noticed this controller has a "key Switch". Did you install a switch and of course turn it on? In not you need to jumper this connector so the controller thinks you connected and turned on the switch. You can use a paper clip to make a small jumper and then tape it over so it doesn't short. You are having the same problem I did. And it was the key switch. If you put a meter on the switch it will actually have a voltage on it. At first I thought I would short something but it worked fine.

I just checked my hall wiring and my controller has the same colors as yours. Of course that doesn't mean they are wired the same. But here's how mine is setup. I copied the info directly from my controller install sheet. And it looks like it matches your controller perfectly. I just don't know what colors you have on your throttle.

THROTTLE CONTROLLER

RED RED VOLTAGE SUPPLY 4.3 to 5V+ Depending on controller
BLACK BLACK GROUND
GREEN GREEN SPEED ADJUSTING SIGNAL 0 - 5V +

Bob,
Thanks for the reply and info. Yes, I did short out the lock plug with a jumper.
The colors coming from my HALL throttle are the same colors as the controller. RED, BLACK and GREEN.
Does not work at all hooked up that way.

I'm assuming that since it operates correctly with a potentiometer ... Red and Black on either side and Green as the wiper, that my controller need an resistive input rather than a HALL effect input. Problem is that this seems very uncommon, and it's much harder to find a resistive throttle than a HALL effect throttle.

Thanks Again,

you can test the throttle by putting the 5V on the red and ground on the black. see if there is voltage on the green wire. if not the hall sensor is toast. you can even plug it into the controller and measure the voltage by putting the probe of the voltmeter into the back side of the plug.

if you can get the throttle open, we can send you a new hall sensor to solder back in place of the one that burned up.

honeywell SS 495 A2 i think i still have one or two.

 

[dumbass]

Jeff, Yeah, it would be very unusual for a new controller to be a pot only controller. Did you check the controller voltage with a volt meter? IF so what is it? As dnmun indicated you should be able to check the hall signal by appling a voltage to it. I think it can be any voltage below 5v so use a few flashlight batteries taped together real good. Or maybe 1 will do it. Didn't you say you tosted your 24v controller? Who knows maybe the hall gave it up at the same time..... Have you contacted the place you bought it and asked them about the problem? When I installed my 48v controller and new hall throttle I was worried about jumping the key switch. I called service on a Sunday and they actually answered and they agreed to I should jumper the key it would work fine. IT might be a good time to call your supplier.

I am stumped. :?

My previous Halls went TU; SP had 0 volts and pulls the +5V line down below 0.5V when connected. I have Maguras but don’t like to use them.

Recently bought two Halls as replacements for the one blown and to have a 2nd spare. I just hooked it up and measured: +5V line is rock solid, and when connected to HE Throttle drops to 4.2V. The SP line holds at about 0.9V (and slowing dropping).

I rotate the throttle and nada, no voltage change to SP. :?

Wiring:

• Throttle to system
  Red -> Red +5V
  White (or Green on some) -> SP
  Black -> Black GND

I have the 2nd throttle so I’ll try that one next. It just seems quite odd to get no change from SP.

Confuzzled, KF

 

[Kingfish]

OK, tested the 2nd HE Throttle and here’s the results:

• When hooked up, +5V line drops to 4.45V and holds steady.
• SP defaults to 0.8V and holds steady.
• Rolled throttle forward and SP goes to 3.65V at WOT.

I must therefore conclude that the first throttle is not behaving well. Make sense?

Best, KF
