Trouble Shooting Summit Slot Machines Trouble Shooting Summit Systems Slot Machines Many of the electronic problems on the Summit Systems slot machines are related to the connectors at the rear of the reel assembly.
All of the controls inputs and outputs to the controller board have to pass through these two connectors.
Clean and burnish brighten the connectors.
Spray both the male and female connectors for best cleaning effect.
Note: As I receive inquires about machine problems, I will try and add the cause and solution to this page.
Identification of the Boards: The Top board of the electronics is the 'Interface Board' Red Handle The Middle board is the 'Slot Controller Board' Yellow Handle The battery is normally located on this board.
Most boards have the battery removed.
This does not cause any problem with the machine operation.
See '' in this section The Bottom board is the Options Board which is the interface to other machines when the machine is used in a progressive jackpot type arrangement multiple machines are connected together.
Normally, this board is not installed.
However, if you purchase a machine with this board installed, you may need to keep the board in to have the machine play.
The options board is also used to control the sound while the reels are running.
This is only if 100 slot machine pull handle have a sound board in your machine.
The sound board is usually located in the top section of the slot machine cabinet.
Over Indexing: see Tilt Codes Over indexing can be caused by one of two things.
Sticky release mechanism or faulty intermittent encoders.
If you suspect the encoders, go through the reel alignment procedure.
This will most likely show up a faulty encoder.
Extra Coins Paid out occasionally : This usually happens when the clutch on the motor fails to engage or is weak.
Try adjusting the clutch device on the hopper motor.
Also, the coin out switch may need slight adjusting, see the next paragraph Extra Coins Paid out and Tilt, Flashing 0 or with any win!
The slot controller board relies on the feedback from the coin activated switch on the hopper.
Each time a coin passes through the feed mechanism it activates a lever and in turn activates a switch.
This switch feeds the 'coin out' signal to the slot controller board.
So first make sure that the switch is being activated by the coins.
To see if the slot controller board is registering the switch input perform the following test: Note: Start with No tilt code should be present on the machine see 'Battery Issues' to disable the tilt code retention.
Play a game, single coin: 2.
During the game play, hold the coin activator lever up on the hopper to simulate a coin being fed out.
At completion of play, the meter should be alternately flashing a -8- and https://money-promocode-casino.website/100/free-100-line-video-slots-no-download.html 0.
This code is coin out jam switch closed 4.
When releasing the lever, the -8- should change to a -9.
Press the hopper reset and the -9- should change to a 1.
Then when you close the door activating the door switch the machine should resume play.
First thing is to determine if you get the -8.
If you do, the switch activated by the coin out lever may just need adjusting.
You can adjust the lever activated switch as there is a screw to accomplish this.
The lever that the coins actuate has a roller near where the coins exit the hopper.
At the opposite end of the lever, there is normally an adjusting screw that actuates a micro switch as the coins go out.
The switch has to 'toggle' with each coin out.
If you don't get the -8- tilt code, the slot controller board is not processing the signal.
You will need a new slot controller board or yours repaired.
The chip that buffers the hopper switch signal is the ILQ-74.
Changing the chip may correct the problem.
We now have this chip in stock.
Coins Won't pay out flashing 0 on the right Digit of the Meter Display : 1.
The electronics to control the hopper are located on the interface board and will require repairs.
The hopper also has a circuit board.
Rarely, this board goes bad.
If the hopper won't run, you get a flashing zero on the display along with the tilt light.
The flashing zero meaning that zero coins were paid.
This problem could be related to bad connections on the plug and jack assemblies on the hopper or the reel mechanism.
To restart payout, press casino free bonus no deposit malaysia hopper reset button and close the door activating the switch on the top hinge of the door.
After 3-4 seconds, the hopper should activate.
See the above paragraph for clearing the tilt and restarting the payout!
Also, see 'Battery Issues' to disable the tilt code retention.
Clearing the flashing Zero on the Right Digit of the display: If the hopper runs, then pressing the hopper reset button and closing the door activating the switch connected to the top hingeshould clear the flashing zero and allow the hopper to run.
If the flashing zero stops for a few seconds, then comes back, it's because the hopper won't run or the hopper switch is failing to signal the coins going out.
Also, see 'Battery Issues' to disable the tilt code retention.
Continuity test for the coin out switch of the hopper: Testing for continuity using an ohm meter.
The 'coin out' input resistor on the 'slot controller' board is R10.
With the machine off, if you are measuring the resistance between 0volts and the end of the resistor that goes to the edge connector circuit board gold pinsthe resistance should go low about 1 to 100 ohms when the coin out switch is activated.
If the resistance goes low, you have good continuity in the machine harness and connectors and the problem is the slot controller board.
If the resistance does not go low, you have a problem with connections in the system usually the rear connectors of the reel assembly.
Testing with a volt meter power on : R10 should have about 3.
If the resistor has 5 volts, the opto coupler ILQ-74 is shorted and will need replacing.
You don't need to call, just pack up your boards, send them to us, Attention: Dick Harkey.
Be sure to include your name, return address, contact information and description of service requested.
Be sure to specify return method of shipment.
Pack your boards using some kind of protection between the boards IE.
Styrofoam, foam, cardboard or newspaper.
The slot controller board is subject to static electricity damaged and should be wrapped in an anti-static material pink bubble wrap or metalized film available at most 'Mail Boxes Etc' and others.
I usually will get back to you in 2-5 working days from receiving the parts.
Note: The power supply is easily removed.
On the left side visit web page is a recesses to reach in and pull it out.
Won't accept coins: The machine has to be in a non tilt mode and the processor on the slot controller board has to be running in order to accept coins.
If the machines accepts coins but does not register the coins, the slot controller board may be defective.
There is an OEM chip in the slot controller that is no longer available and is always the reason for not casino free bonus no deposit malaysia the coins in.
You can order a replacement board or send in your board for test.
Sorry, I don't repair slot controller boards.
If you purchase a slot controller board, I will apply the diagnostic fee toward the purchase of a new board.
Accepts and registers coins but won't start play.
If the handle is allowed to be pulled handle release solenoid was activate then the slot controller board is waiting for a game in progress signal from a switch.
The switch is located on the side of the reel assembly and the two wire from the switch go to the back of the electronics mother board and plug in there with a 2 pin plug.
Make sure that the plug is attached and that the switch is activated by the pulling of the handle launching of the reels.
See above for board repairs and click to see more testing.
It keeps track 100 slot machine pull handle the coins played, the number of coins in the hopper, the status of the last game play and of course maintains the last tilt code.
To erase the memory, pull the jumper located next to the battery.
The jumper has to be removed for 5-10 seconds for the board to lose memory.
When you turn the machine back on a '-0-' will appear in the coin payout window.
This code just means that the memory was re-initialized.
When you press the hopper fill button, you are telling the machine that the hopper is full of coins now.
Typically the full count is around 2000 coins.
So, if you hit a jackpot and don't have enough coins to pay out, you have to re-fill the hopper, press the hopper fill button and close the door.
Closing the door signals the slot controller board to continue paying out.
Note: The battery is not necessary for correct operation of the machine.
One customer found that without the battery, he go here hit the jackpot after power up and 20-30 plays.
This is the only instance of a battery related issue that I have heard of.
Coins Accepted, but Handle won't release The handle release coil located above the handle mechanism has to be energized thru the back connectors of the reel assembly to release the locking lever for the handle.
Place a metal screwdriver near the release coil.
If you feel the magnetic pull of the coil, then the problem is mechanical.
If there is no magnetic pull, then one of the following applies.
This can be confirmed by measuring the resistance of the coil.
If the problem is mechanical, most likely there is a groove that has been worn into the release lever.
This is where the armature of the coil and the release lever come in contact with each other.
The armature should be fairly easy to push and release the locking lever.
If it feels 'stick' lubricate or file off the groove in the release lever so that it allow smooth movement of the armature.
Handle Release Issue: New and Old Interface boards not completely compatible.
The old style interface board red handle had mechanical relays black rectangles.
The new style interface board has opto-couplers and Triacs solid state.
The old style interface board applied 120 volts to the handle release solenoid.
The common or return for the 50VAC is join. 100 free bonus casino malaysia can yellow wire.
Locate and make connection to the yellow wire casino free bonus no deposit malaysia in the machine to the handle release solenoid.
Note: The 50VAC is isolated from the 120 VAC, this is why there is no power to turn on the handle release solenoid!
Tilt's often: Please email me the tilt code, and I will put an answer to the tilt reason here on my web site within 48 hours unless I am on vacation.
Tilt's Codes Won't Clear After pressing the Hopper Reset button on the power supply, the machines waits for the door to be closed.
There is a switch mounted behind the upper hinge of the door and the switch should be activated by the hinge door closing.
There is about a 1 second delay before the game is allowed to proceed.
There should be a plastic piece mounted to the plunger of the switch.
If the plastic piece is missing the switch will not be activated by closing the door.
I have them in stock if you want to order it complete door switch.
ILQ-74 Inputs and Outputs switch buffer The ILQ-74 chip is used to buffer all the switch signals of the machine.
It is the most common failure for the slot controller board.
IE won't read the coin in, count the coins out, etc.
The following is a list of inputs and outputs.
Note: All of the inputs go to resistors and then the ILQ-74 chip.
So I am giving all the connections on the slot controller board.
Use the battery - minus connection as the common measuring point.
Same as the black wire with the red stripe on all the switches.
You can order this chip from me if you have the skills to replace it.
Pin 70, to R9 to Pin 7 of ILQ-74, output Pin 10 if the output of the ILQ-74 is bad, the game is waiting for the signal to go high.
Nothing will happen as long a this signal is wrong.
Pin 74 to R11 to Pin 3 of ILQ-74, output Pin 14.
Note: While measuring the input or output of the ILQ-74 the related input and output should change state as the switch is being pressed.
Sounds and Sound Issues Some machines were wired for sound and others only used the jackpot bell as coin-in indicator and win indicator.
The machines that were wired for sound have a sound board and speaker behind the upper light assembly.
The sound board is 100 slot machine pull handle to the machine via a small board mounted to the cabinet just behind the reel assembly.
The sound interface board has a 20 pin connector on the left and a 16 pin connector on the right.
The most common problem with sound issues is that one of the reed relays on the interface board becomes stuck switch closed.
By lightly striking the reed relays small rectangular black body you can un-stick the contacts.
The indication is that a chirp kind of sound is generated when the machine is powered up.
There are 3 sounds generated by the 100 slot machine pull handle />Coin-in the coin-in switch is directly wired https://money-promocode-casino.website/100/bet365-casino-bonus-100-rules.html the first reed relay on the left.
Reels running, this sound signal comes from the option board.
I have just designed a replacement for the options board blue handle for those who would like to get the reel sound running.
The last sound is of course the jackpot or coins paid sound.
This sound is generated by the 'bell' circuit.
All of the sound boards that I have seen utilize opto-isolators for the input commands.
You can troubles shoot the board sound board by performing the following.
Short pin 4 and 5 of opto-couplers U1, U2, U3 respectively.
This should activate each sound.
Pin 1 of the opto-coupler H11B2 has a 'dimple' and you count counter clockwise.
So pins 4 and 5 are on the opposite side of the opto-couplers as the input connector.
If the board makes sound, the problem is the interface board behind the reel assembly.
All Reels don't Spin when Handle is pulled or don't always spin Turn off the power, pull the handle, If all reels launch the problem is a shorted driver on the interface board.
If some reels don't spin, the problem is only mechanical.
Lubricate all the joints on the stop levers the levers and mechanism for stopping the reels.
All of the pivot parts of the stop levers should move freely.
