trouble with Coin comparitor, please help

[jbshocks]

Hopefully someone can help a little on this. I have a 1987 CEI hotslot.  It had lots of issues which are all solved.  I no longer have any codes but it won't take money.  It has a cc-40 coin comparitor in it.  SER 116494.  Picture attached. No led comes on even with door switch closed.  It diverts coins to the tray.  I have measured voltage at 13.8.  Any ideas?  Do I need a new one?  Is there a part on the circuit board that typically fails on these?  I have only seen these listed as 12 and 24 volt, is the tolerance such that mine is a 12 volt with 13.8 feeding it?

I'm assuming you have swapped sample coins and tried adjusting the sensitivity (all the way CCW,then just a hair CW). No LED lit with door closed is not a good sign. Have you tried measuring the voltage to it?

As a temporary workaround, you can tie the diverter back so all coins are accepted.

[jbshocks]

voltage to it is 13.8  I tied back diverter and they just drop through

Drop through to where? The tray or the hopper?

[jbshocks]

The drop to the hopper with the diverter jammed open.   Other wise to the tray.  I have attached 2 new pictues one is an optic at the bottom of the cc-40.  That makes me think that the cc-40 is fully self contained without a separate coin counter.  Is that a correct assumption?  I am a little concerned with the 3 wires to no where in the picture and hoping they don't go to a coin counter.


Anyone have a machine with cc-40 on here?  Does it have integrated coin counting optic with no additional counter?

I don't really know anything about that machine, but is sure does look like that slot behind where you have the 3 wires would be for a coin switch.

[jbshocks]

I am a little worried about that slot behind my fingers.  Ever see a slot that uses a micro switch to count coins?

Yep.

Here is a post about a Bally just yesteday with a microswitch issue.

If that CC does have an optic, I have no idea what it is used for. But those three wires make me think you are missing a part.

[jbshocks]

I just checked voltage on the 3 wires.  The black to white/red is 120 volts AC.  I am sort of thinking that may be for an optional light.  Ever hear of coin counters using that much voltage?

[poppo]

That seems high. Might have to wait for someone who is more familiar with that CC and machine.

But that slot and bracket sure look like it was made for something similar to this. And the wires are right there.

The plot thickens.  I looked at my igt s that has a cc-16-c and it is a 12 volt unit and identical to the cc-40 other than lacking the optic. In what may have been a risky move I put the cc-40 in the igt.  The led lit up and it accepted coins.  So at least everything other than the optic which is an unknown,  is working.

[jbshocks]

Do these differences in wiring mean anything to anyone?

Here is a pinout for voltages on the CC-16 from the old Universal manual. This page is from the Coin Mech. Inc manual.
This is an early version. The CC-16 went through more revisions but the 12v, 24v, wiring remained the same, I believe.

Also, on my Universals (non-inhibit)the voltage is always present, door open or not, the ground is controlled by the mpu and is disconnected when door is open to break the circuit.
When you check the voltage use the ground supplied to the comparitor to determine if the mpu is actually ready to accept coins.

[jbshocks]

Anyone know what pin 2 violet is used for on an IGT?

[uniman]

After looking at more recent CC-16 schematics I see that the earliest CC-16 had voltage options and they also had units just 12v.

Let me be clear, I know nothing about a CEI

This is kind of like comparing a orange to a apple

CDS machines use a CC 46 24 VAC INH compaiitor, this CC does have a built in optics.  The CDS machine doesn't have any other way of counting coins other than the CC optics. In other words no coin optics below the CC and no micro switch.

Buzz,

What do you make of that bracket that looks like it's for a switch and those 3 wires? Do you think THIS machine does use the built in optics,  or just has them, but it's not used. After all he said he put it in his S and it worked (i.e. just ignored the optics).

Do we even know if this is the original CC model for this machine? Maybe someone just stuck it in there (like when he tried it in the S) and the optic is not being used.

Just trying to figure out if it's one problem or two (i.e. just the CC not working for some reason and thus the optics also don't, or the CC doesn't work AND it's also missing a coin switch).

Looks like you already have a white micro-switch.
Just missing the trip wire.

It that actually a switch there?   I thought it looked like just a bracket for one (the two offset screws)  And where are the wires or switch tabs? A better picture would help. 

[proten]

Could some one been trying to get the comparator with
optics to work as a replacement for
a comparator with out optics and a switch?

[jbshocks]

I am starting to think the coin comp may have been swapped.  It worked in the igt which I expect is 24 volt and won't work in the  the cei which as 13.8 volts.   I am thinking about hooking 24 v up to it in the cei and see if it works..  I see that cc  40 comes in 13 and 24 v

[jbshocks]

that bracket is not a switch and I don't see marks where one was mounted.  I wish some one had one of these.

How about moving the 13v from pin 4 to pin 5? Believe the CC-40 12v uses pin #5 and not #4.
In your pic it looks like it's on pin #4. Right?

[jbshocks]

I tried moving from 4 to 5 and it did not work.
