IGT S2000 "Door Open MB" error - FIXED

[dpalmi]

Hello all!

Working on a new to me IGT S2000 and I have 2 errors I can't clear.  It was working fine so I'm not sure what changed.  It seems I can't get the machine to realize the main door is closed.  It gives me 2 errors - 1st one is "Door Open MB" and the second one (I don't have the exact wording - I will post it when I get home) talks about the bill stacker.  If I go into the test/options menu, when I close the main door - it doesn't exit the menu - so it's not seeing the door closed.

Things I checked - the belly door switch is bypassed - wires are shorted together, the cash can switch is bypassed - wires are shorted together, I checked the door emitter optics with a digital camera and can see it is working, I replaced the door optics receiver with a spare I had and I verified the optics are lined up correctly.

I went into the IO tests for the Main Door and it shows just a "1" - I assume this should be going from 1 to 0 when the door is closed.

I ran out of time last night playing with it - so I am just looking for other things to check - let me know and thanks!

Doors switches on the S2000 are tricky and differ between the upright and the slant.

So which do you have?   I guess upright?

Did you install a different MPU board?   I have seen this issue be a result of a bad MPU board

The door in the front (belly door) has a swich which is tied into the main door as well

B is bill as you pointed out but if it's a slant that changes the landscape.

I usually shine a light into the receiver to test it, but if It's not working it won't change.  Two different receivers you tried, I would trace the wiring.  I also seem to remember someone saying that the cash box switch on an s2000 shouldn't be bypassed as the machine needs to know it opening and closing sometimes, others said this wasn't true, if all else fails, I would open this connection then close it again.

good luck,

The cash box switch on an S2000 if tied up will cause the top light to flash and not clear unless it sees it open and close.

That is what I remember for it. 

The one thing I read from his post was it was working fine and then stopped.     My question is did anything change?   Was he doing a game change etc?

Yes...upright.

No - MPU not changed.

The door in the front (belly door) has a swich which is tied into the main door as well

Belly door switch has already been bypassed...wires twisted together.

I usually shine a light into the receiver to test it, but if It's not working it won't change.

I will try that - but tested the sender with a digitial camera and can see that it is flashing - so I don't think it's the sender.  If it's the receiver - shinning a light won't help....

Every S2000 machine I have ever touched always has the cash can switch bypassed with the wires twisted together - so I don't think the switch needs to be there - but I will give it a try.

I was cleaning stuff in it - but nothing really "changed" - I've only had this machine a few days - but it was working fine before these errors - including the door opening/closing.  I wonder if I bumped a connection somewhere...I will trace the wires too.....

Thanks!

agreed, re-seat all and check their connections to the backplane.

Any idea where these connections go to on the backplane?  The wires get bundled in with a bunch of others and it's kind of hard to figure out where they go...anyone know off the top of their heads?

Make sure the machine is level, you can mark the cabinet and the door where the optics are and when door is closed they should line up, if not on a level base the cabinet will be out of rack

I took the reels out of the machine so I could see the alignment with the door closed through the reel glass - so I can see they are lined up.  I will play with it more tonight and post my results...but thanks for the suggestion!

I would almost bet the MPU board is bad. I have about four or five of theses doing the same thing. Do you have another board to try ???

I do have another and will try that tonight - that would sure eliminate everything else if it suddenly starts working.  I would be surprised because I didn't do anything to the MPU - but will try and let everyone know....

I agree on this but I take off the optic and line it up by hand to eliminate this as the issue.

Also moving the door open handle up slightly to see if it's miss alligned but I gather from his eariler posts he eliminated the optic?

S2000 can be a pain in the but when it comes to door switches, not the best design in my mind....

You didn't pull any Player Tracking out of it did you?

the problem i had was with the belly glass - there is a switch on that puppy too!!!

for some reason they tied that to the main rather then calling it belly like other machines

Hello all!

Ok - the game is up and running!  Wohoo!!

So here is what I did.

When I got home, turned the machine on - same issue.  So I grabbed another MPU board and swapped it out.  After clearing all the errors - that board worked fine.  So not the door or anything.  I put the original MPU back in - same issue...so the board is bad, right?  Well, I always try things twice...so I put the spare MPU back in, cleared the errors/etc...and then put the original MPU back in and now it magically works fine.  I did have re-set the denomination with a keychip - but now the machine works fine with the original MPU in. 

I know...it sounds crazy.  I didn't change anything but the MPU board twice.  Does that make any sense to anyone?

Thanks for all the suggestions...glad it's up and running

It's good to hear you got it going.  You used the keychip on the problematic board? Which keychip?

Thanks,
Wayne

[StatFreak]

Maybe the original MPU has a bad/cold solder joint, an intermittent open or short, or a component that is failing?
If so, then the problem will resurface down the road. If not, then no worries.

[dpalmi]

You used the keychip on the problematic board? Which keychip?

Yes - I had to use a keychip to set the machines denomination.  FYI - the door issue was already fixed before that because one of the steps after holding the test/setup button for 2-3 seconds to clear the errors is to close the machine door and the machine recognized that I did that.  I believe it's a keychip 17.

I have seen this issue be a result of a bad MPU board

So far when the door switches just don't work after checking them all I move on to the MPU board.  I have seen the 9 out 10 times.   Glad to hear you got it working.
