    Hey Guys

    I'm having new machines installed and the electrician cut power to the whole breaker box. That cut power to my change machine. When the breaker was turned back on I had the "Please Wait" light lit up solid. See the attached photo.

    I opened the case to see what the error message said and I got no error message, meaning (I think) that the system was ready and online. See attached photo.

    The changer won't take bills and the Please Wait remains lit, so I tried unplugging and replugging the controller. At that point it shows the PWRFAULT message but I'm not sure if that's because I unplugged it or because the breaker was switched off.

    I called my change machine guy, who says there's a problem with the power supply and I need to pay for a service call. I want to see if anyone here might know of additional troubleshooting steps before I pay for the call.


    TIA

    These changers MUST MUST MUST have a VERY VERY VERY good ground! It sounds like your 40 watt board got fried. Order a new one. They just plug in. The older boards were not all that great but the ones they have now are actually pretty good.
    You might be able to adjust the old one but for the life of me I can not recall what to set it at. Don't take this as gospel but I think it is 4.1V? That is the potentiometer on the 40 W board. You better call Standard to be sure.

    I had this same problem a couple months ago.  It was the 40 watt board.  The Standard website has a good explanation of this common problem with the SC600 changers.   FYI -  The board is easy to install.

    Joe & others,

    It probably is the 40 watt board.  Ideally, someone would come up with a better test than just checking the voltage points.  I did my due diligence with my multimeter ... but the intermittent problem still occurred until we replaced the power supply with brand new!

    The old board actually did well with the 500E. Beyond that it is not strong enough. I used to buy a 60 Watt board for years to take it's place but that company in the bay area is gone. From what I understand the new replacement is actually more like a 45 watt which is why it works so well.

    ​I have had the same changer as you since  about 1995 and have changed the power supply twice. Its simple. Paid for the part only. Call Standard Changemakers. They're very helpful. It may be under warrantee.

    I totally agree with the others here about the 40watt board, and the grounding.
    Get 2 boards so you always have a backup. Change machines are a pinch point in your mat, almost as bad as losing the water. You never want to have one down for long.

    I always kept an extra hopper AND bill acceptor in stock as well, so I could quickly swap them out.
    Yes, it costs a few bucks to buy these parts (you can ask Standard for rebuilts), but you will have the peace of mind that you can always get your changers up & running right away.

    I have a Standard coin changer, it dispenses both DC & Q.  My machine was going out of service as soon as a dollar bill hit the bill receptor.  I have already changed the 40w board, as I thought this would do the trick.  Not so.

    What else could cause the machine to go out of service as soon as a bill hits the accepter slot?

    Laurence,

    Did you try cleaning it with a soft rag & a small amount of moisture?  Blow cleaning with air?

    After that ... did you try swapping out with a known good verifier?  If the known good one works ... you probably need to send in the problem verifier to an authorized repair shop.  Usually, the swap isolates the problem to the specific section ... ideally, of course would be a less costly specific component within the section though.

    Does anyone find that they get a better deal sending in their verifiers to some authorized repair shops vs sending it in to the factory itself?

    Agree with Michael on the blowing out and swapping.
    I would add to clean the bill pathway with a clean rag moistened with alcohol. Q tips as well.

    Dont forget get that the cable connections could get twitchy so spray them with contact cleaner and push the plugs in and out a couple of times.

    Good luck!

    So I have a Rowe changer that for the most part works. I didn't know that the bill acceptor could be swapped  just to test the functionality of the Standard. If bill acceptors will transfer, I'll try this today.

    I have already tested connections and cleaned the bill acceptor in the Standard, so at least I had the right ideas to troubleshoot.

    Many thanks.

    Reviving this thread.  I swapped out the board and cleaned the power cable with contact cleaner. Im still getting the power fault error.

    The changer has a grounded outlet box inside the cabinet. One side of that outlet is wired directly to a dedicated circuit breaker. The power supply plugs in to the other side. Im going to run an extension cord from another plug in the mat to see if maybe that outlet is bad.

    Any other thoughts on steps to troubleshoot before I call the serviceman?

    Hi Joe,

    Try swap out the bill acceptor with a known good one. The bill acceptor board may be drawing too much power or may need to be repaired. You may also call Standard Change maker technical service again. They will teach you how to test the power supply board with a multimeter. You can observe if the voltage on the power supply board changes as a bill is inserted into the bill acceptor.

    Try this just to see what happens. Remove your stacker and place a box under verifier. If it works fine like that either your power supply is weak or you stacker is using too many watts.
    This is a long, long shot. Is it possible your building does not have a good ground? Check the ground wire at your panel.
    Check to see if there is any voltage between the neutral wire and the ground. If there is any at all your neutral does not have a good connection.
    These changers are kind of like the canary in a coal mine. If your ground pipe has deteriorated over time you may want to take a look at it. Perhaps run a new ground wire to a cold water pipe?

    Hi guys the changer FIX read this
    On most changers  the bill gets read at 7 to 8 places with optic sensors and audio
    Yes Sound. and speed of the bill done in milliseconds.
    From the time the bill in inserted in  the bill acceptor  the set of sensors 1&2  checks to see if its a real bill .   travels to optic #3&4 reads bill to see if its a
    1 5 10 or 20
    Now it gets rolled over a sound head (just like in a tape player) the bill sends out a a secret audible  sound to a processer because the ink has metallic ink and put in a special way to distinguish bill amount. then goes through 2 more optic sensors.
    the trips a paddle blade and that trips another sensor. then proceeds to the bill stacker and will trip another optic sensor or a mag reed switch. To tell the  main board that  the bill is in place  now vend the change.
    Now with the power supply the use a multi tap transformer some use two or three power feeds going to different Ic boards any wear from 4.7 v  12v and 27v  DC.
    theirs a lot of information going on in you changer. just to watch your money.

    So *8 sensors , one audio head , read the bill at 7  places on every bill. and stack it in ones, in stacker A and 5 10 20 in stacker B  then say its ok to vend.Then count each quarter going out the hopper  then gives you a count what went through the changer and out count. and gives you repair ERR CODES
    THE FIX FOR THE MOST PART
    Make sure the optic sensors are clean use a Qtip with isopropyl alcohol, also clean the pintch rollers (rubber or plastic) and the belts cause the speed that the bill gets pulled in  it is crucial if it dont see  the bill hitting the sensors in their designated timed sequence it will reject the bill.WOW WHAT A MACHINE.
    Their are many more test points in the machine but with out experience and lots of mistakes ( buying parts) i could go on and on,
    PS. Get to know your VOM meter its your best friend in the coin op business
    Remember your changer is the heart beat of your laundromat .
    Good Luck,  Guys its a long road of problems. In the Laundrymat busuness
    And I still run into problems after 30+ years    Cheers

    Al,

    Yes, in my experience, bill changer transport (validator) timing is key.  As you pointed out,  each bill check point occurs within miliseconds of the previous check.  Dirty or worn belts can reduce transport speed enough to cause excessive bill rejection.  A small piece of torn bill stuck under a sensor will shut the whole bill changer down.  A dirty maghead will also cause excessive rejections.
