IGT S+ Error Code "GRADR=???"

[Weissa1989]

Hey Guys!
Hope you're doing good so far.


Since begin of this week I'm officially owner of an IGT S+. 


First start up shown the error 12. Battery was changed - error 12 thrown away.
But there is a new problem... Error code 61.
According to a lot of topics here the problem could get solved by press the "test" button for about 3 to 10 seconds then the error code 61 switch to 61-1 and so on...


My problem is that there is no possibility to come to 61-1...


Do you have a hint for me what I can do?


Thx guys.

Did you press and hold the button until you hear a ding sound.
See ricks faqs on the front page.

[Weissa1989]

I already read that there must be a sound after press the test button. Unfortunately there is nothing while I'm pressing this button. :-(

[Amechanic]

You might want to test the button with an OHM meter to see if it working.

[Weissa1989]

You mean I have to do a voltage measurement?

[jay]

Resistance measurement across the button. To see if the button works.


If you changed the battery do you have a clear chip ?

[Weissa1989]

Understand. I will check on that.


I have only changed the battery - chips haven't been changed from my site.

[Amechanic]

Some S+ machine for some reason Need a clear chip after a battery change.

[Weissa1989]

Bad news. :-/


Which chips have to be exchanged?
Do you have a hint for me where I can buy those?
I have to say that I'm located in Austria.

There are two chips that you should procure.


1. Clear Chip - used to reset system back to factor reset. You remove the game chip, insert the Clear Chip, run the clear, remove the clear and re-install the game chip.
2. Set Chip - this is used to activate the bill validator. This is done basically the same way. Remove the game chip, insert the SET chip, set the denomination, Remove the set, reinstall the game chip.


You would rarely need to use the Clear chip. Usually this happens after a battery change when the cmos has become corrupt.
The set chip is needed anytime you do a game change or after a clear has been run.
If you don't have a DBV then the set chip is not necessary.


Most of the vendors on here would probably send you a couple of chips even though its international. The other option is if you have an Eprom burner you can burn your own chips, and all you need is the software binarys.

Are you pressing the right button? The little one right next to or behind the power switch

[Weissa1989]

@Jay: So I have to buy those 2 chips. Is there anything I have to know to buy the correct chips?
Do you know someone of this forum who will sell and send?


@Elvis: I have pushed the small white button next to the power switch - error code 61 occurred.

If it's not allowed to post a eBay link inhere please delete.


On eBay I found 2 chips, which may help me to get the slot run.
Are those 2 the correct parts?

The Set 15 and the 123 Clear chip should be fine for your needs.
The price is good, looks to be about $20 in shipping to your location.


If your looking for parts the people with Banner advertisements on our home page are great to work with. We don't sell banner ads the space is given to those who are known to be helpful to NLG members.
With that said - the price from Ebay appears good, and I can't see that international shipping is going to be much less regardless of who you go through.

[Weissa1989]

Perfect.


Do you know for what a SP731 Chip is?
Because there is a second set for about 16$ even with a SP731 chip.
Should I buy this set - just safety first?

Your S+ has two important chips.


One is called a Reel Chip and the other is a Game Chip. Each chip has a number associated with it.
If you go to Ricks FAQ on the home page of the site - bottom right - there are instructions on how to get your machine to display these values.
Alternatively - when you remove your MPU board (large tray behind hopper) ---- *** ONLY remove with power off you will clearly see these two chips on the board and they are generally labeled with their numbers.


The Reel Chip is the theme of your machine. It is what makes it a 2 coin double diamond or a 3 coin Haywire, or a 5 coin triple diamond deluxe,  etc, etc.... change the chip, change the machine.
- if your changing this chip you would typically also change the glass, and reel strips to match.
- The chips come in different pay back %%%, again I refer you to Ricks FAQs and something called the IGT game bible this will tell you the number of the chip for which game.
- Again if your chip has a payback of 78% and you want a 98% payback, change the chip.
- Associated with this chip is a document called a PAR sheet. (Paytable and Reel) - it describes the theme in detail, the reel strip order etc.




A Game Chip controls the behavior of the machine. Type 0 is the most common type of chip and is used with games that have no special features. If you were to get a game like Double Diamond Deluxe .... this game nudges the reels up or down depending on which way diamonds are pointing. Balloon Bars nudges up if the balloon shows below the pay line, SlamDunk nudges down if the basketball shows above the payline. I believe this is a Type 5 chip (but I am just going from memory here). Haywire is another TYPE and then there are Buy A Pay games that are another TYPE as well.
- The Reel chip will determine what TYPE of game chip you need.
- There are a lot of different Type 0 chips. Some had to do with different gaming regulations for specific accounting, then early S+ didn't support progressives so that was added, later support for linked progressives were added. Then later a combination of linked, non-linked and multilevel progressives was added.
- Depending on the game chip you have options to ring the bell every time a win is made (ie 2 cherrys) or just when the top award is there, or never. Reel sounds on/off etc.
- The options for your game chip is described in a PSR sheet. (Program Summary Report).


Coming back to your question the two most common type 0 chips are SP731 and SP1271. The SP731 has the option to play music when you win rather than just DING DING DING ... there are 7 - 9 songs to choose from. The cavet here is 1.) Your game needs to be TYPE 0, and 2.) the theme has to support the song capability (only about 20 of the 60 themes do).
The SP1271 chip was a major upgrade for the S+ and added tons more accounting features to the platform, unfortunately for the designers to do that they had to drop the music.
If your machine recently came out of a casino it is most likely that it would have the newer 1271 and as your home would not be subject to gaming regulations requiring specific accounting, a 731 is often more desired so you can set the machine to play music on the wins.


When you change from a 1271 to a 731 or vice versa this will create another error on your machine .. something like a 63-? or 65-? usually these clear (instructions in Ricks Faq) but this is again another case where a clear chip might be necessary if the error doesn't clear like it should. What happens here is that the CMOS gets reformatted for the different accounting functions.


Before you buy the SP731 you should check what Reel and Game chip are in your machine and cross reference against the IGT game bible to see if its compatible with your theme.

Sorry for such a long winded reply.

[Weissa1989]

Ok. So that's truly not so easy as it seems.
Remove old chip, plug in New chip... :-(
I have to take a look on my motherboard. I will take a picture of it and post it so I hope with your help I will get the right once.


Here is a picture of my slot - Austrian version. :-)

[jay]

For the Clear chip and Set chip - swap, press a few buttons, swap again, very easy.
Instructions for both are with Ricks Faqs


If you are changing Game Chips you need to make sure its the right TYPE so its compatible otherwise slot won't work.
The wrong chip won't hurt anything but it won't help either... ha ha.
...... Its kind of like saying Alcohol won't solve your problems, but then neither will Milk.
Worst case is that you would need to run clear chip again.


Make sure you look at the IGT game Bible for the list of chips, and see Ricks Faqs on a game change.
Once again a game change is changing glass, reel strips and chips.


Over the years I have collected over 60 different game kits for my machines.

Where I can see on that auction if the chips are matching with my machine?
There is no information (number like it's mentioned on igt bible) shown.


Or I miss out something in this auction?!

1. What chips are currently in your machine ? - This is fundamental to know before making any changes.
 
2. Once you know this you can make a request to the NLG community (in the Looking for section - as a new thread) PSR and PAR sheets for chips SS2299 and SP9922
*** the SS and SP numbers I just used are made up numbers get your chip numbers as per item #1



3. You can look up your theme in the IGT game bible (Ricks Faqs has the bible) at the top of each theme it says the Game type for that theme. Both the PAR sheet and the game bible will tell you what TYPE of Game Chip you need.  The PAR sheet is just way more detailed.
ie
3 Coin Multiplier Black Tie (139A) (TYPE 0)


4. As you are looking at some Random Chip on auction you can again request a PSR sheet for it and that will tell you what TYPE it is. Or you can just ask and someone on this site can probably tell you.Or you can ask the seller - What TYPE number is the chip ?
