Another bad coin acceptor?!

Well-known member
Well this is strange. Have my bays set up with Dixmor LED7 timers and Ginsan acceptors. Had one just stop working about 3 weeks ago. Today a bay would take a quarter and the word coin was displayed and just stayed there. Called Dixmor and they said the acceptor is putting out too long of a pulse. Then without prompting, he asked if I had Ginsan acceptors. Not a good sign. I'll call Dan up there and ask what changed. Those things used to last forever with almost no maintenance. Anyone else seeing this?
 
Yes in a way. We have a 3 dollar start with 5 min runtime and once the customer puts in the 3 dollars and will start for about a second and then stop. We have had our Dixmor timers rebuilt about 4 months ago. Dixmor is claiming it is our Ginsan coin acceptors causing the issue. We have been using this setup for years. We are in the process of looking into a different brand coin acceptor that Dixmor will comply with but I agree with you mac on what could have changed.
 
"COIN" will display if the coin pulse circuit is stuck closed. If you unhook the red/green wire, "COIN" should immediately clear. If it doesn't, the problem is in the timer or the wiring.
 
There have been zero design/manufacturing changes in over 15 years on the Sensortron. Even then, the design change we made was to make them impervious to magnets. It was at least 10 years before that that any other change was made. As for the Dixmor shutting off, all the timers in this industry have some level of overload protection. Check what is running when the timer cancels out. That function is starting to have an issue. I've also seen a failing rotary switch arcing and spiking the timer causing it to shut off.
 
We have LED6 & Sensotrons on our 10 bays. Has worked great for years. Had a Sensotron go out a few mos ago, but it was an early 2000s model!! Sent it in & Dan fixed it perfect

Dixmor timers have no internal protection. If a dead short exists, the timer display goes out, then it reboots with remaining time and goes out again. The only thing that would cause it to display "COIN" is if the coin circuit remains closed.
 
Just had a newer, less than a year old, sensortron start giving multiple 3-4 credits per coin. Luckily I was there and heard the horn giving rapid fire credits. Changing out the acceptor fixed the issue...Generally the Sensortrons or pretty reliable, some I've had in service for about 20 years. Usually when they fail, they stop sending a signal to the timer. I have a few that have died over the years, so I might call to see if it makes sense to fix them v/s buying new.

You are absolutely correct. But, if the timer is "shutting off" as chevyguy09 said his were he needs to look at load, switch, or the timer itself. I see it a lot when customers hooking up brand new doors into really old, beat-up equipment.

Yes, I just didn't see chevyguy09's post and was commenting on the OP.

I thought so. Another thing I just remembered is transformer size. Too many times, with all of the upgrades being done, people don't check to see if they have enough VA rating on their transformers. They need a minimum of 100VA, per bay. A lot of older equipment may have 75VA or less. That low power will really screw with any timer.
 
I dont know whats up with yours, but I've had a lot of flukey timer issues in the past. Morry at dixmor said I had a massively high repair rate...
This old thread details some of the changes I made to fix some apparent electrical issues, maybe it will help.

I'm not certain, but I think the changes that likely had the biggest impact toward solving it were:
- In my limited life experience, I've learned to always check the fuse first, then check, doublecheck, and re-check the ground. So to totally eliminate grounding issues as a possibility, I added a separate ground rod exclusively for 24V, and double checked it every frikin ground wire on the property.
- replaced ALL 25 year old 24V transformers.
- moved all "extra" equipment from 24V bay transformers (eg weep, other relays, etc). At the same time I isolated ALL solenoids with a relay bank (yes I was desperate - I freely admit this may have been overkill)
- replaced 30 year old control wire to bays (lots of corrosion and worn-though spots on the insulation - also wanted to add more functions)

electricity is like voodoo to me. I understand it and can do it, but its still mystical.
 
I had a problem with led6 timers showing coin also and we determined it was interference from the coin acceptor and the electronics of the timer (led 6) Before crytopay we used led 5 and timemaster And never had this issue. We did talk with both slugbuster and Dixmor about this problem 6 years ago. We placed a aluminum plate between the timer and coin acceptor and problem was solve. IDX did not cause but sensotron and slugbuster did. If we could move timer 1/2 inch up or down this would not cause interference. The picture is to show where our timer and coin acceptor line up

Dan,
I was under the impression that repairs were no longer an option for Sensotron or is it just the Multitron?? The Multitron was a reliable work horse but the new World edition has been nothing but trouble. I have one that's dead after less than two years. I will send it in along with the older units if repairs are possible.
Thanks.

I did in fact have some rotary switches go bad and now that they have been replaced having no issues so far. Thanks again for the idea on that!!

The Sensortrons are repairable if less than 15yrs old. The cost is $50 per unit. Just contact me for a RMA before sending anything in.

As for the Mutlitron, I classify multicoin acceptors in the "truck argument". Everyone has their favorite and legitimate reasons why they like them. Some work better at some sites than others. They're actually pretty complicated electronics so I assume it's the various operating environments each wash would present. I have several customers who feel the opposite you do. I don't even suggest a particular brand anymore, just try a couple different ones and see what works best for you.
