Can a bill validator operate (accept bill, stack bill) on its own without being connected to a changer to draw power? Can it be connected *JUST* to a battery?

Thanks!

uh no.......any validator operates based on information fed to it from a coin mech , or electronic board, info like machine in stand by, coins available to make change, product available etc. .....to decide weather to accept a bill....there are simple inexpensive, testers available that simulate the functions mentioned, allowing you to at least test......your post is a little vague, but i hope this helps you

Thanks for your reply. I bought an AC-500 and took out the hopper with the change bin. In essence it is a large heavy metal box, power supply, validator with stacker and a lock. The changer is occupying too much space so I thought of "surgically" removing the board, validator and connecting the validator to just a battery, but don't know if it will work. I took pictures and they are below.

hmmmm.....thanks for the pics.....the ac series changers require 110v that by means of transformer steps down and regulates the "consistent" voltage requirements to function.......as you noticed, i used the term "consistent" voltage........electronics can do some crazy inconsistent things when supplied with "dirty" inconsistent power..... i have seen fluctuations in ac cause problems....so my best answer is no it wont work......i will however compliment you on creativity.......nice to see someone is thinking outside the box....guys like that usually invent solutions......

One last question:

If I took everything out (grounding the circuit board) and reconnected the power supply, would it still function like it does now or would I run into complications?

Can you tell me where you can buy an inexpensive tester and what are they called?

[djpvending]

the last ones i new of were sold by a company called capital vending out of the east somewhere....its been several years....but they were around $100 and were good for basic testing.....more expensive models are available from vendors exchange in cleveland...

There are battery powered validators available, not sure what application you are looking for. As stated in other posts, the validator needs some sort of information from an outside source to determine if it should "accept" a bill or not. This is known as the inhibit circuit in a simple scheme. It can get very complex depending upon the interface being used. In a very simple scheme, this circuit may be over ridden with just a jumper in the correct pins of the connector. Do not try to jumper anything if you do not have a wiring diagram and/or a schematic (and know how to read it) as you could easily blow up an IC on the control board. We can force almost any validator to accept and stack a bill, but why?
