Dino Solomon - 28 Jun 2004 14:11 GMT
Hello,
Last night i brought a GP (Electrifly) Triton (NIB) from my LHS. (may by a
big mistake.....  ..)
I tried to cycle my transmitter NiHm battery (directly out of transmitter)
and after discharging>delay between disch. and charging> i received this
error "open circuit"
All connection is perfect, not cable defect, improper plugs etc.
I tried also the direct charging function and after battery checking a loud
bip and the same error on screen.

My procedure was incorrect or this charger is defective. !!!!!

Need help !!!!!!!
Arne - 28 Jun 2004 15:49 GMT
Why would you want to cycle a NiMH battery?  Most recently mfgr'd NiCDs
don't need cycling....

If near enough, why not take it back to the LHS and see what they have to
say.

Cycling is a good way to determine the remaining capacity of a
battery, which is a good thing to know.  While you're flying is not a
good time to learn that your battery only has 20% of the original
capacity left.

Open Circuit means that the charger is not seeing the battery.  A
diode could cause that as Red has suggested, but the Triton CAN charge
(not discharge, though) through a diode.  You said the problem
happened at charge rather than discharge?  Perhaps something broke at
that moment.

I assume the charger has a fuse or two inside, perhaps that blew?
(I've never opened mine up.)  If so, you'll probably want to send it
back for repair rather than void your warranty.

Try to cycle your receiver pack, see if that works.

| > My procedure was incorrect or this charger is defective. !!!!!

Well, you haven't said how you checked your cables -- it's possible
that they're bad, though it's pretty unlikely.

| > Need help !!!!!!!

Well, as suggested, going back to the LHS isn't a bad idea, unless
it's not so local.

There is probably a diode in the transmitter charge circuit. This would have
to be bypassed in order to charge directly through the transmitter jack.

I read that as the battery was installed in the tx and he is trying to cycle
it thru the charging plug.
Could be wrong.

He said he charged it OUT of the transmitter! No diode there!

Are you schizophrenic, or what?  Right after this post, you make the
same suggestion, and yet you're correcting Red now?

You seem pretty fond of correcting people who aren't necessarily wrong
for some strange reason ...

Actually, the Triton *can* charge through a diode -- it just can't
discharge through it (which is to be expected.)  Obviously it puts a
small amount of current on the output port and then measures the
voltage, rather than just measuring the voltage without any current.

Somebody suggested that it can't charge at high rates through a diode,
which seems odd, but I'd suggest not trying -- running a lot of
current through the charge circuit, which was designed to handle 100
mA at most, doesn't seem smart.  It probably wouldn't fry the radio
itself, but could certainly make sure that you have to remove the
battery to charge if you fried the charge circuit.  My radios seem to
tolerate one amp through the charge circuit -- and I don't want to
risk anything faster.  If I need to charge them faster, I remove the
battery.

Yep the triton is awesome, but you very likely have a Diode tha
prevents discharge from the charge port.  Just remove the battery fro
the TX

Some chargers won't charge it either as they can't read the voltage
the Triton won't at higher rates.

Did you remove the battery or leave it in the transmitter? If it's out of
the transmitter, then it's either the charger or a bad pack. If in the
transmitter, it's probably the diode as everyone here says.

Try charging the batter out of the transmitter. Most likely the diode in the
tx is preventing the charger from seeing the battery.
I have a Triton charger and its the best thing since sliced bread.

Ok . Thank for yours try to help. Maybe my English is not very good / clear
but my battery trans. pack was out of transmitter. I own a Futaba 9c and the
pack have like servo connector with only two wire, one red and one black. I
used the regular receiver charging cable.Not diode in this circuit.

The charger is defective and my LHS change it. The new one is OK. BTY, how
can I know if this one have the improved / update software ?

Thank again for yours time.

Dino

Jeboba,

My Triton can deliver only 2.5 amps where I need 4.5 or more. I didn't
know much about chargers and bought the first one  offered by the LHS.
I believe the Triton is very good for what it can  do, but now I'm in
the process of replacing it.

I had to charge and charge again 4 to 5 times on my 1500 mAh, 11.1 V
3S Li Poly battery to get it up to voltage. If I was lucky, the
battery may be charged on the first try.

Anyone in the market for a good charger and not need more than 2.5
amps?

icrashrc,

I tried to respond direct email to you about "How much shipped?", but
I guess I don't know how to remove "my-wife" : )

My email address can be accessed directly from this thread. So if you
would email directly, we may discuss how to get the Triton charger to
you.

If you look at icrashrc's e-mail address, you will find said
string of letters in his address.

Take out the offending letters, and the true address will
be revealed.

Thanks, Marty. icrashrc has responded to my email. Since then I found
out how to make my Triton charge my batteries to 12.60+ V.

Perhaps I could be of help if I described how this came about. I went
to LHS where I bought it for help and they called Triton tech support.
Their phone number is on the back of the manual. (217.398.0007)

In the course of discussion, the tech person asked me to set the time
limit to at least 100 minutes. It was set on no time limit before.
That is, it was set on zero time so the charger was timing out.

Then someone else at the shop reset the turn off emperature to about
10º over the ambient temperature, that's the temperature of the
location where the charging takes place.

Now the Triton is working as it should.

I hope this could help.

Well let me just correct one statement I made.  Yes the triton ca
charge with the TX battery inside the TX and the Diode in place.  I
will however terminate that charge when using higher charge rates
mine does every time.  Just an FYI.....

Mike, how high of a charge rate? I regularly charge my Futaba
(including a 9ZAP that has the diode built into the removable batter
itself) at between C/2 to 1C at the field without problems (or so
thought). Anyhow, I would very much like to become educated before
put too much trust in that aspect of Triton use.

Thank

pda4you - 29 Jun 2004 14:42 GMT
Lomecevak - mine charges at at rate for about 5 minutes but anythin
over about .3 amps it terminates as I don't think it can read th
battery voltage.  

My Airtronics with no diode can be charged at any rate, so I know i
has something to do with that.  Strange that your are able to.

Mine is older and does not have the "update" green dot, so maybe tha
has something to do with that.  Strange......

I believe Futaba finally eliminated the diode when they brought out the 9C.
At least that's what I've heard. I can field charge my 9C just fine but not
my 6XAS.
