Hi Guys!
My name is Eric and I'm interested in to buy an IGT S PLUS slot. But the slot shows an error code to that I can't found anything. The display above shows following error code: "GRADR-???" Also see the attached picture.
So I hope, that one of you experts can help me to solve this issue.
Thanks for your help! ;-)

That is the progressive jackpot. Not really needed in home use. Any other errors on the display near the reels?

Weissa1989 · « **Reply #2 on:** July 09, 2020, 10:53:57 AM »

Hi!
Nope. There is no other error code shown on the displays.
According to the sellers statement the slot doesn't work.
Only the lights are shining but no chance to get the reels work after you put some money in... :-/

Sorry - I'm wrong!
On the display "winner paid" stands "1"...

It probably shows 12 for a dead battery. Try to get a picture showing the lit displays. If using your phone reduce the size of photo

I try to get a picture of the small displays. ;-)

Do not see any new picture, only the one of the top progressive display.

The GRADR=??? is on your progressive displays, and is likely saying that the Group Address is not set or not found. Assuming that you're not connected to a casino progressive system, that could be the cause.

I have not seen many 4-reel IGT S+ machines. Can you post a few more pictures of the entire machine, please?

Also, are you able to tell us what the SP (GAME) and SS (REEL) chips are in your machine, either by removing the MPU board (with the power OFF) or with this method?

Also, can you provide some pictures of behind your top glass to determine what kind of progressive controller you have?

That is the progressive display that has the error - the display is technically called a meter and not an error message with the slot itself.
On the S+ the Coin In and Winner paid windows would have errors like 12 (battery low) 3100 (hopper error) etc. I don't see any errors on the slot that would impair its functionality.

From a progressive display perspective these meters would be connected to a Cham II or Cham II+ controller board.
The ChamII+ (plus model) is a standalone progressive controller. All in one board that handles the progressive and displays the progressive amounts
The ChamII (non plus) requires the board to be connected to a CON2i SuperController (~~$800 unit) and is only a display unit.
The "i" on CON2i means IGT - you can sometimes find a CON2s or CON2b etc but you need the "i" version to work with IGT.

In a casino you commonly would have a bank of machines all connected to a common jackpot progressive - this is called a LINK progressive and that is handled by the CON2i SuperController.
The environment would look like several machines with ChamII (non plus) all connected to a single CON2i
When you don't have the CON2i controller (ie a machine is pulled from the casino and sold) you typically get the type of error message that you see displayed on the progressive meter.

You also can get these errors if this was a slot with a standalone progressive and the ChamII+ has been off for a while and the built in (rechargeable) battery has gone dead and the board needs to be reprogrammed.

To program the progressive (either CON2i or ChamII+) you need a custom 9 pin serial cable between a laptop and the (CON2i or ChamII+) controller board. You can take a standard 9pin cable and easily modify it as it basically requires a couple of pins to be jumpered. I take the brute force approach and cut a standard 9pin cable in 1/2 and do it that way with a bit of electrical tape. Lots of doc on this site on how to do this. You also require a program called PSP, which you can get from one of our members. As a side note the PSP is old (old) non windows software and works best on a old laptop with a physical 9 pin port. If you use a USB to 9pin adapter cable sometimes the PC will identify this as COM8 and the PSP only supports COM1,2 or 3.

The ChamII+ can be used as a ChamII (link mode) but not the other way around. So it is possible that this machine was used as part of a bank of linked machines but still has a ChamII+ board.
To replace a ChamII (non plus) with a ChamII+ board would be ~ $120 and would give you full progressive capability.

Once you have identified if this has a ChamII or Cham II+ lots of folks on this site can help you program it and there are manuals floating around as well.

From a slot perspective - this appears to be a good solid S+ machine that has many of the progressive components that people buy as add-ons. So if the price is right I would snag it even if you don't end up using the progressive at the beginning - you can always just pull the power to the meter and get rid of the ugly errors.

Hope this helps.

Wow. I hadn't noticed the four 7's for 4 reel

jay · « **Reply #10 on:** July 09, 2020, 04:58:07 PM »

The S+ can support up to 5 reels.
I understand that 5 reels are common in Oz but I have never seen one much less a 4 wheel version.
This is indeed a rare beast - I would like to see the reel tray and see if the reel assembly is any different.
I am sure the wiring harness is different as mine has connectors for 3 reels. Is there 4 plugs or 5 on this harness. Enquiring minds kinda wanna know.

Good morning gentleman!Thank you very much for the quick and informatial reply!
This slot is actually not in my possession. So when I buy this beautiful piece, I will send all required pictures which will help you to help me (

) to get the slot run. :)First of all it's good to hear, that i can "disconnect" the meter so that this bad "error message" is gone - problem one will be solved. ;)But the 2nd problem is, that (according to the seller) the reel don't starts after put some money in it - and that without a error code in the litter - or does "1" mean any error code?What do you guys thing - is there a chance to get the slot run when i exchange the small battery (on the motherboard i guess?!)?
Thanks for your hints and have a nice friday.

In the only picture you posted it says Winner Paid 1 - which means that the last payout was 1 coin.

I doubt there will be any problem to get your slot working properly. The S+ are very durable and replacement parts when needed are low cost.

Why won't it run when you put money in ?? could be a variety of reasons - and more information will be needed to diagnosis the actual issue.
For instance when you put a coin in - does it go to the hopper or fall out to the coin tray, does it increment the credit meter or just stay blank.

Common issues
- No sample coin in the comparitor - if the machine was recently taken out of service then they would have emptied it of all the cash and likely the sample coin put in the comparitor.
- Although it doesn't show on the pic - I assume this has a bill validator - if so there should be a cash can. This might be missing so the machine won't play (even if its not needed).
- Often they remove the interior locks when a machine is sold - so the interior door in front of the cash can might be slightly ajar - The machine won't play. Closing the door or a small piece of tape to hold it closed will fix that up.
- Door optics might not be lined up so the machine thinks the door is open (this is unlikely as there is a 1 in the winner paid window), alternatively the optics could be damaged.

Nothing earth shattering..

You mentioned that you would need to change the battery ?? I am not sure what leads you to that conclusion as there is nothing on the slot that is indicating the battery is low ?

jay · « **Reply #13 on:** July 10, 2020, 08:21:03 AM »

As a soon to be slot owner there are a few things you probably don't know.

1. The theme of your machine is readily changeable by changing out the glass, reelstrips and 2 chips. You can often buy what is known as "game kits" that have all of these parts.
- You can change your machine into a 5 coin, 2 coin, 3 reel etc.... there is nothing that can't be changed though a simple game change.

2. You can change the payback %% of your machine by changing one of these 2 chips (called a reel chip).
3. On the main page of this site - bottom right there is a section called RICKS FAQs that has lots of information on how to do a game change, how to change various functions like reel sounds etc.
4. In this same section you will find the IGT Game Bible which has a listing of all of the various themes available and the various chipsets.
5. After a battery change sometimes the internal CMOS memory of the slot gets out of sync and you need to do a factory reset - this requires a Clear Chip - not often do you need to use this but having one around is handy so if the seller of the machine has a clear chip I would pick this up as well.
6. The bill validator needs to be reset after any game change and sometimes for other reasons (this is common) this requires a SET Chip - If the seller of the machine has a SET chip I would get one of these also.
7. Enabling or disabling some progressive settings also require the use of a Set chip.

With respect to the "chips" mentioned - there is a removable board that lifts out - this is called the MPU board.
There are two chips in sockets on the MPU board - Called Game and Reel chips. You simply pop out the Game Chip and pop in the Set or Clear chip, put the board back in and then you are able to change certain settings of the machine. You then reverse this process and put the game chip back in.

I guess I do have some concern that the 1 is in the leftmost position on the display. I believe that if it was indicating that the last payout was one coin, the 1 world be on the far right side of that display.

Without having the machine in your possession to see what it's doing or not doing, it's tough to diagnose it.

Weissa1989 · « **Reply #15 on:** July 12, 2020, 01:18:35 PM »

Hello gentlemen!
That the diagnosis is though to say even the slot is not mine is completely right.
Today I have seen it "in real" and I have bought it.
I will bring it to my house at the end of July and then I will send a lot of pictures and questions.

For now I want to say thank you.

Weissa1989 · « **Reply #16 on:** July 12, 2020, 01:43:23 PM »

One further small questions... ;-)

Where I can buy a manual for an IGT s+ (includes troubleshooting instructions)? Ideally as a download version. :-)

Eric

therockinelvis · « **Reply #17 on:** July 12, 2020, 04:10:54 PM »

The manuals are pretty much useless. On the inside of the front door is a label with all codes. This site is 1000 times better than any manual

jay · « **Reply #18 on:** July 12, 2020, 06:23:44 PM »

I agree that the manuals are pretty useless but as a contributing member we do have a downloads section where you can snag the manual or another kind member might send it to you if your profile is up to date with your email address. As a contributing member you can also post to the classifieds for a WTB (want to buy) or WTS (Want to sell) ads. I however suggest updating your profile and do not provide the email in an open post otherwise some bot-net might scrape it and you will be buried in spam.

Weissa1989 · « **Reply #19 on:** July 12, 2020, 08:56:24 PM »

I thought that a noob like me will help this manual. ^^
But if anyone can send me this manual (also for a view paypal-bucks) I will appreciate that.
