Coin out counter, E-130-10

[DavidLee]

Okay, got the counter fixed. Both originals had broken advancing armatures. Only needed to fix one as I found good one in salvage.
Made a new replacement part and shoulder bolt. The shoulder bolt was conceived from the end of a reel index arm. The original
was pressed, peened over and needed to be ground out for removal.

Call Larry at 702-363-9998, he has lots of EM parts.

Larry and Bad Baud are the best in the business.  You will be sure to get a good part in working order.


Happy New Year All

Interestingly, those counters are still manufactured and available for purchase. Unfortunately they only make 24 VAC counters and not the 48 volts we need for our Bally slots. I wonder how well a 24 VAC counter would work in our machines?

Zzzzztt POOF !!

[RiseLikeRa]

Sounds like the smoke genie will be released.  Understood.

I tried a 24 vac, very erratic and hot.   No advance, advanced correctly and counted 3 for one pulse.    24 vac is a no go.    I would buy 10 originals  if I could find some.    A surplus store has them (48 vac) but slightly larger to where they don't fit by reels.    Use them in back upper corner for jackpot counter. 


Taken non working ones apart, usually cracked plastic on stepper part inside.

Thanks for the information. The counter I have has a blue label, TAB and Bally Electronic Counter model E-130-10. If I where to get a 24 volt counter, I would switch out the coils.
Most likely will work on them as to figure out why they don't advance.

[rdaniel]

I have a suggestion regarding the 24 VAC counters. Would it be possible to place a resister in series with one side of the 24 VAC counter to reduce the voltage going into the counter?  Resisters are used to reduce voltages in our slots why not for counters?

or just wire two 24 v in series

How's it look for you dav


Richard I just found a red candle Toppers again your counters and the Pauper will be in the mail this week

[rdaniel]

Thanks Jon. I appreciate all of your assistance.

The best thing is to use voltage-regulator (7824). The regulator transform >25v down to 24V.

[Badbaud]

No. The regulator is a DC device, not AC.
A 2:1 step down transformer would work but which one would be the question.
If you used a resistor you would need to determine how much current the meter draws when stepping and then calculate the resistance and power rating of the resistor so it doesn't smoke.
Simplicity dictates get another 48VAC counter.

[DavidLee]

Jon,
Still working on why the counters stop working when the coil works good.
I'm assuming the mechanical portion is worn down.
Going to see if I have a working counter of the same style.
Think I have 8 to 10 in salvage.
Hope to come up with a simple fix if possible.

I forgett to say that you need a AC/DC-bridge (4 diods)....

[Badbaud]

Well, lets do some math.
Lets say you want to convert the 48VAC signal down to 24VDC with a regulator.
The 48VAC is the rated RMS voltage of the AC signal.
The peak AC voltage is RMS x 1.414 which calculates out to 67.872 VAC peak.
Adding a full wave bridge using standard silicon diodes - two diodes have about a 1.4V drop across them so 67.872 AC  peak minus 1.4V equals 66.472 VAC peak.

Looking at the data sheet for a LM7824CT you can see the regulator has a maximum input voltage of 40 VDC.
A pulsing, because we have not calculated a filter capacitor, DC voltage of 66.472 VAC would be to high for this regulators input voltage.

[rdaniel]

Thanks Badbaud. Now that I am more confused than ever, perhaps it will be best to simply use 48 volt counters.

For those who wish to purchase 48 volt counters there are some for sale on e bay. See web site below:

Thats correct! I have not work with Electronic development for 16 years now so I cant the data on LM7815 in my head any more.
A sollution is to use a zenerdiod Before the regulator.
BUT! The easiest way is to meassure the impedans of the counter (let say it's 500 ohm) and put a resistor with a equal value or Little bit higher (560 ohm).
