Error 21 nightmare

[StatFreak]

That is the last thing you should be doing right now, since there are errors that will not clear with the optics bypassed. I suggest that you first get your door optics working, then fix the coin optic and any other issues, and finally look into bypassing the door optics with a switch once the machine is up and running, if that is still what you want to do.

OK stat freak....i did the camera test and the optics on the door side pulse purple so i believe they work...dont know how to test the reciever though
As for the cash box the roller device was broken off when i received the machine so i just taped it down(in the closed position)

I also removed reel 3 so i could see if the optics lined up with the door closed and as far as I can tell they did. How perfect do they have to be??  my door sags a little bit and you have to lift it slightly to get it to close and wiggle it to get the door key to come out. 

Man these machines are driving me nuts!!!

[StatFreak]

If the optic is pulsing, follow Jim's advice and try input test 13 again. The state should constantly change as he posted. If not, then either the receiver-side is faulty or the optics are not aligned properly.

I don't know the approved method of aligning the optics, with a Sharpie marker I put a line on the outside of the door that lines up with the optic in the full down position.  Then put a mark on the cabinet side the same way. Close the door and compare the black marks. WD 40 will remove the marker ink.

K+ for the sharing of the idea.... I knew we keep you around for something!!!!

IF in input test 13 you get the constantly changing between 0 and 1 repeatedly then his optics are working.
They will only go to s solid one if you shine a flashlight at it.
The reason is the door LED is flashed at a specific rate by the MPU logic and the output of the LED has to match the input from the receiver or the machine will not think the door is closed or something is open.

I want to add to Foster's post in hopes of clarifying that the flashlight method
only works on the receiver optics - not the emitters.
But I'm sure you would of guessed that...lol

ok guys here is where we are today......both machines are now passing the #13 door optics test
Machine A's  "Coin in" tests are  is (A)10 1, (B)11 0, (C)12 0..............
                    i can't get A or C to change but I can get B to 11 1 as I drop a coin.
Machine B's coin in test  (A)10 0, (B)11 0, (C)12 0..............
                       no changes during coin drops

what is the significance of the 10 0 and 10 1?  why are the difference?  I am looking to order new coin in optics times 2 for both machines.  still dont know if my coin comparators are working properly.  both have 24v coming in but i had  to jabmb the rakes with paper to divert the coin to the optics instead of the coin tray.  will the CC work at all if I have the 21 error?





Edited to change brackets [] to parenthesis () to avoid an issue with the "B" optic being changed to a bold tag

When you have a tilt or error the machine will not enable the coin comparator to accept coins. The rake will be in reject coins position.

If you are testing the optics you can take the coin comparator out of it mounts it only clips in place.

I just did the test to see how known good machine should respond in the tests.
I could not get it to change on the 10, 11 or 12 tests. I think the coin drops so fast the test modes do not show it.
I also tried the test credit button on the optic only one that changed from 1 was the 11 test it would go to 0 as I pushed the switch and back to 1 when released.

The player display did not even flicker.
And I am using a 16Mhz board, it still will let extra coin go to hopper and not count it if max coin is reached. It give the coin back at the end of the play.

I am glad you have the door optic working.  long story short!  digital electronics operates on a binary number system,which means only two numbers, 0 and 1, a 0 = a low state or ground,or that it is off. a 1 = a high state or a positive voltage  in ttl logic usually 5vdc. indicates that it is on, so the code is telling the operator that test 10 is a 1 or that it is on.  the circuit has a voltage applied to it and it sends an infra red light beam thru the tiny holes in the black coin optic encoder to the receiving detector, when the detector receives this beam it is turned on and sends a command to the computer that it sees the light beam  and the computer tells the operator that info by putting a 1 in the display. when you disrupt that beam by putting a coin into the black encoder it reverses all that logic and puts a 0 in the display.
you can fashion a device that resembles a pop cycle stick and use it to put into the coin encoder and break the beams with it.this is a better way to do this opposed to dropping a coin thru. and you can test it many times over. as Foster said remove the coin comp. and you can preform the test  using the stick and observe the results.  test 11 will change from a 1 to a 0 everytime you press that small white button, you are shorting out DS2 the B emitter.  that whole assembly can be swapped between machines easily, remove the two screws behind the cc and remove assembly and unplug. on the optic board itself , I usually remove Q-2 or Q-4 depending which version board you have, it will usually fix test # 10,  on your B machine ,  you may have a V+ problem , thats the voltage that powers  the three emitters.             Jim

Have you taken the coin optic out/apart and cleaned it ?

I used to get a lot of 3200 hopper errors - cleaned the optic and never had a problem since.

[knagl]

The comparator is a red herring right now.  Whether your comparator is working or not, it won't be the cause or solution of a 21 error.  21 lies completely in the coin-in optics.

As Foster confirmed, the optics should read 1, 1, 1, when the machine is idle.  If they aren't, you need to repair or replace the optics.  To avoid further frustration, I'd suggest replacing the optics with a set of known good ones.  If you don't have any, one of the vendors on the site (like Jim at Blueridge) should be able to supply you a set (or two) of S+ coin-in optics at a reasonable price.

Once we get the 21 error dealt with, then we can work on the comparator.  When the machine is in an error/tilt condition (which it is now with the 21 error), it's expected behavior for the comparator to reject coins to the tray rather than allow them through to the optics.  The comparator has to get the "everything's okay" signal from the machine before it will try to allow matching coins to pass to the optics.  Since everything isn't okay with the machine, the comparator rejects every coin.

[kgin504]

Ok guys it had been a few busy weeks but I have one machine up and running due to all of the great advice and a great experience with my first transaction with Jim at blueridge.  Now what I am running into is that the machine wil not accept multiple coin drops.  Only takes one credit at a time. If additional coins ate dropped they go to the hooper but are not registered as credits.  I can push the white button on the optics to generate multiple credits or hit max bet button if I have  multiple credits available but can get it to register but puting in additional coins.  What gives?

[jay]

It would really depend on your theme....There are 1 coin, 2 coin and 3 coin and 5 coin themes.

On my 3coin IGT slot - if I drop in 4 coins. The reels spin, and at the end I get 1 coin spit out from the hopper.
On another 3coin IGT slot if I drop in the 4th coin the coin simply falls to the coin tray.
The difference between the two is the game chip.

Perhaps you have a 1 coin chips and 3 coin glass ?     post your reel chip number and someone can clarify for sure.

Usually 1 coin games are like the $5.00 or $25.00 type themes and the dealers that have them can tell you what albotroses they are to sell.

I would not be surprized that a "parts complete" machine may be sold this way.

[knagl]

Is that happening every time or just sporadically?  If it's the latter, it's possible that your optics have the "large coin" guide in them and that coins are falling through the optics but are not being seen by the optics to register a credit.  If it's happening every time, you've got me stumped -- I presume it's more than a one-coin theme you have in your machine?

[stayouttadabunker]

It sounds like the rake on the back of the coin comparitor isn't staying open long enough
and is getting caught after the the 1st coin drops through..
Remove the CC and turn it around.
Behind there is a "rake" that's held there in position with a solenoid and 2 screws...
loosen up the 2 screws and move the body of the solenoid so the
rake does not touch the sides of the rectangular hole opening.
Once in place, tighten the screws and re-install.
If the problem persists - check to see if the rake arm is bent.
Bend it back so the rake doesn't touch the sides when
the rake is closed & also when it's retracted.

Also, wiggle the 2 gray wires going in to the top of the CC.
There may be an oxidized pin causing the rake to lose its power to the solenoid
after the solenoid gets energized as the 1st coin falls through.
I doubt it's this and more of the above though, but oxidized pin
connections will give one flaky and intermittent performances.

Anyways, this is why I think you're only getting the optic boards to
read one credit each time you try to throw in 3 coins or more.
For kicks, try one coin per second...I'll betcha it will register as a credit every time. lol

[kgin504]

so...it looks like rake on CC is fine.   drop door open still flashing  on the candle.   I read some post saying that the drop door was actually part of the lower stand not actually the cabinet.  I read that if you connect the wires together you can bypass the error I have not tried this yet.  If i go into th input tests i cannot get it to switch from  31 1 to 31 0.  I checked the cherry switch on the cash can door and this cause no effect either.  Whats wierd is that this machine was functioning last night after i switched the optics and today i have this error.  Again i cannot get it to accept more than one credit if i am inserting coins but can hit the white button on hthe optics in test mode or hit max credit on the panel if i have winnigs accrued and can play 3 credits.  wonder what is going on?? any clues?  this is a $1 double peppers 3-coin progressive machine.   I have two 2 conductor wires that come out of the bottom that go to the lower stand (looks like they hook up to magnetic alarm trans/receivers on the stand doors) also i have a 3 conductor wire with a plug on the end orange, white , gray(does any one know if these need to be terminated or not for my machine to function??

[knagl]

The wires leading to the magnetic sensor in the stand are the drop door wires -- twist those together and it'll see that as closed.

Keep in mind that the lower section of the candle flashing does not always equal "drop door open" -- it can signal many different things, typically that the main door was just opened and closed, and a paid game hasn't happened yet.

I can't fathom why it will register the first credit but not any subsequent credits.  Can you please post the SS chip number of your machine so we can be sure it has the correct software?  You can determine the SS chip by following the instructions listed here.  The fact that you said that the max bet works if you have winnings built up indicates that you do have 3-coin software, but I'm stumped.

Is it accepting the first coin and giving credit every time, and ignoring any subsequent coins every time?

[kgin504]

woot woot all is well on machine #1!!!!   Butt connected wires from cabinet to stand and it fixed all issues.  accepting all 3 credits now!!!??? paid game had to be completed to turn off light....

off to fix machine two thanks guys!!!!

[B-52BadByron]

I had a 21 code that would not clear,  I replaced  the  power supply connector and that fixed the problem.  Maybe that might work.

uh...Byron,
kgin said he fixed it 16 days ago...
