Old Doyle Vac LED7 Retrofit

[2Biz]

It can be done!

Looks good. It's hard to tell - did you notch the faceplate of the coin acceptor?

Yes....I took a "Wiz Wheel" cutoff tool and cut the base of the coin acceptor back to the upright piece that is spot welded to the base. I cut between the two mounting holes the width of the timer. That was about the easiest part of the modification. Cutting the readout slot was the hardest thing to do. I used .187" diameter carbide end mills and broke a few before getting all 4 of them done. (I retrofitted 4 vacs...) To minimize the radii in the corners, I had to use that small of a cutter.

very nice looking clean work.

1. Where is the 24V Transformer?
2. Why the "Mounting Blocks" rather than just mount thru the timer slots.
3. Are you planning on going to Cryptopay? If not, why upgrade?

1.) The 24v transformer is under the dome.
2.) I didn't have access to a stud setter and wanted to use the decal. So I had to come up with a clamp that used SS carriage bolts with a bolt pattern outside the dim's of the decal. I also had to cut down the decal to make it fit. There was coin a return hole that needed plugged that I wished wasn't there. So I pressed the head of a SS carriage bolt in it to cover it. It was almost an exact fit. Something else that needed worked around.
3.) I doubt I'll go with Cryptopay? I had the mechanical acceptors (even though they were new) that were problematic. Canadian and bent coins were plugging them too often. My Bays have Sensortrons and LED7 timers and its very rare that I have a jam. So now my vacs should be as dependable as the bays.

That would seem to be an acceptor issue and not a timer issue.

2Biz,

Great & ... as usual neat & precise work by you. Ouch ... on the cost to replace those carbide end mills???

Those single coin mechs by either Parker or GinSan are 100% reliable based on over 25 years of using them in our 6 bays ... it is a crying shame that dollar coins are not the dominant coin here in the USA ... then your sign could say add extra dollar coins for more time. As you know I set up my Dixmor LED7s to give bonus time for dollar coins (less time for quarters). I use IDX X20s multicoin mechs from Jim at Etowah that weren't moisture proof enough in the bays but are 100% reliable when used on the Vacs.

Your Vacs are the same originals that we have with the heavier stainless than the newer vacs I believe. We added a neat looking shroud from Industrial Vac if I remember right over the cleanout padlocks with Medeco locks because of too much trouble with middle of the night scavengers. Those heavy stainless steel shrouds helped the appearance of the vacs a lot as an added benefit.

Are those special Wago terminal nuts that are an improvement over plain old wire nuts?

NA...I didn't use the Wago wire nuts. I had never heard of them when you posted about them a while back. I just used the old trusty twist wire nuts. I make sure to use the ones with the metal insert and not just plastic. I've never had an issue with them.

About the carbide end mills. I bought an old Elgin knee mill years ago that came with lots of end mills, most of which were carbide and cobalt. I think I have a lifetime supply! But little carbide end mills like that arn't expensive...Maybe $10- $15 bucks...Here is a 3/16 solid carbide E.M. from Shars for only $12.67....So not too expensive.

Yea Earl, I know the problem was just the acceptors! I had the newer Paraplate Timers, But I wanted that damn Coin Drop Horn!

 

[MEP001]

Is the horn in the dome too? I put them in the box with the timer just to not have to run more wires.

If you decide you don't like the carriage bolts and hold-downs, I've made studs in stainless by drilling the correct size hole for #8-32 threaded rod but not tapping it completely through so when I cut a piece of rod it will tighten into the hole. It took me a few tried to get the depth just right, but the hole almost disappears if the end of the rod tightens where it's flush with the surface, and of course if you put a decal over it you won't see it at all.

 

[2Biz]

The horn is in the box with the timer and coin acceptor. Its wire tied to the 120v line coming up through the box. Its loud enough you can hear it over the vac motors and just right when dropping coins....

The carriage bolts and clamps work ok....It would have been a lot easier to do it the way you mentioned. But the plate is only .100" thick. That's only three threads or less if you stopped short of going through. My old faceplates had carriage bolts that secured the coin acceptor frame. I don't think it looks all that bad. Just a bit more work.

Update...The Sensortrons and LED 7 timers have been installed about a month and I can say it hasn't been without issue. I've had to send 2 timers back and 2 sensortrons had issues of rejecting coins. One acceptor would reject the first 4 coins then accept the next 50. Let it sit for 5 minutes, then it would repeat the same thing.

The first led7 would jackpot and rack up 100 minutes on the timer. Dixmor said it could be caused from a chattering switch in the acceptor, but switching out the timer with a new one fixed the problem....Same acceptor still working today. Dixmor said the problem turned out to be an opticoupler issue. The second timer quit crediting coins. This one made some unhappy customers.

After talking with Dan at Ginsan, he said the acceptance issue was caused by a dirty coin path and to clean the coin path with alcohol per instructions. Doing so didn't help a bit.

I have this same combination in my bays and never have an issue. Been in service for over 25 years. Seems to me 50% failure rate is a little high for new equipment.

For now, I have everything working correctly and will bench test the faulty sensortrons before sending them back.

Am I the only one experiencing these kinds of issues with this combination?I've read about the sensortrons rejecting coin issues, but I thought the led7 was a bullet proof timer. Should I give the sensortrons a bit more time or have some slugbustes on the shelf waiting to go in?

 

[2Biz]

I figured out what was making the sensortrons reject coins. So I don't have to send them back.

If anybody is throwing them in the dumpster, let me know and I'll pay for the shipping from you to me!
