CEI Hot Slot - Need Help

[rokgpsman]

ok, thanks. I'm wondering if a standard 3.6 volt battery could maybe be connected to the correct 2 places on the mpu board to do what this smart battery is doing. If so that would be much easier and lower cost to replace when needed. Generally the battery voltage is just to keep the cmos ram alive when the machine is powered off. I believe the smart battery provides a longlife battery voltage plus it has an output signal to tell of impending battery failure, some circuit boards don't use that feature.

I have to say that you guys are really terrific, and thanks for all of your help.  I have an embarrassing question that demonstrates that I am probably in over my head.

When I received the reel error "E41r", I removed the Opto-Sensors and cleaned them to make certain that they could "see" (even though they are IR).  I replaced them and then realized that the harnesses that connect the lights with the sensors are interchangeable.  I never expected that this would be possible, hence I did not pay attention to orientation when I removed the wiring harnesses.  I replaced them all so that they are configured the same, which means that they are all wired correctly or all wrong.  Here is a picture, along with a picture of two spare opto-sensors that I received when I bought the machine.

Finally, I have ordered a replacement Dallas Smart Battery DS1260-100 from Hong Kong, with a date code "0722C2  090762".

I tore our whole library apart and could not find schematics.

ok, thank you for looking!

See attached. I found this on www.datasheetcatalog.com

Shows where a battery could be attached.

[PowerGenSeller]

Got it/ Thanks.  I'll let you know when the new battery arrives.

Any thoughts on the wiring scheme of the opto-sensors?

[Badbaud]

red and black is usually the anode (red) and cathode (black) leads.

[PowerGenSeller]

The red and black wires on this device go to the servo motor.  I am fairly confident the LED side is wired correctly with orange on the anode and green on the cathode.  As far as the reflective sensor, it's connector has two colors, purple and blue.  The purple is connected to the anode.  The blue to the cathode. 

Therefore, I believe the opto-sensors are all correctly wired.

I usually take a quick photo of something like this before I take it apart. Good insurance for when you put it back together. Especially if it will be some time later, my memory isn't as good as it used to be!

There is another person here that recently bought a CEI Hot Slot. He could verify that your optic sensor is connected the same as the ones on his machine. Because you both have the same or similar machine it might benefit both of you to contact each other and compare stuff on the machines that you have questions about. Here is the recent discussion thread for the other person:

One of his questions is about the reel strips, if they should all have the same part number or can one be a different number. Can you check the part number on your 3 strips and report what they are? Thanks!

[PowerGenSeller]

Yes, thank you.  I have responded to his request.  My reels are sequentially numbered, 4012 #1, 4013 #2, and 4014 #3.

[rokgpsman]

Thanks for checking on those strip part numbers and helping him. He can probably send you a photo of his optic sensor if you have any doubts about how yours is connected, but if your machine is working ok I'd say it is wired properly. Do you know of someplace that would have information about the actual strip part numbers used on his machine? He'd like to confirm that his machine's strips are the correct ones and what order they should be installed.

Unfortunately, I have very little information and do not know where to turn for more detail, other than this blog.  Thank goodness for NewLifeGames. I am in the process of contributing, although the process is not so straight forward.

Thanks for the URL links. I donated $50 using the first link.

I just received a new Smart Battery.  I installed it in my machine and checked the voltage on the chip as suggested earlier.  The voltage on those pins is still reading -0.01vdc, basically the same as before.  However, this Smart Battery seems to work as well as the original one - at least I am back to getting the original error code of E41r.  I will try one more trick of replacing all three opto-sensors with new ones.  The original sensors were made by TRW and are not available anywhere.  I can't even dig out a drawing or info on the TRW sensors.  I will buy three new OPTEK Technology model OPB703 sensors.  The attached drawing shows that they are physically nearly the same and have the same lead configuration and electrical connections.  As with the TRW model, they emit IR and use a NPN output photo transistor.  I will make certain that they are adjusted to 3.8MM from the reflective surface, as shown on the diagram.

After that, I am out of ideas.

Thank you for your donation!

Do you mean the voltage on the CMOS ram chip is missing, the measurement Badbaud mentioned back in reply #10? If the SmartBattery is good but the ram chip isn't getting the voltage then maybe a circuit board trace is broken. When stuff gets unsoldered and removed sometimes a circuit board connection gets broken. You can inspect the traces going from the battery to the cmos ram chip power pin and the ground pin. Or do a continuity check with a meter on those 2 traces from the battery to the ram chip.

Powergenseller do you have more pics of inside I don't know what wires connect to coin switch I just got this machine and wires are just hanging there

This is a nearly 6 year old thread. The OP hasn't logged on in over 5 1/2 years. You might want to post a new subject in this forum for the CEI.

That's what I was afraid of
