10. SCRIPTION System Description The AC400B is a bill changer that accepts dollar bills and pays out four quarters in its standard configuration and is also programmable for various other coin token payouts What is unique about this machine that differentiates it from standard change making machines is that it draws its power from a battery rather than from an AC wall outlet Inside of the changer is a 12 Volt Sealed Lead Acid SLA battery that is connected directly to the Logic Board and that powers the AC400B s complete operation Also inside the unit is a 12 Volt bill validator that accepts 1 bills only and a 12 Volt Compact coin hopper that dispenses one type of coin typically quarters NOTE This section describes the standard configuration AC400B Other configurations are possible if specified at the time of purchase A typical changing operation begins with a bill being inserted into the slot on the front of the machine shown in Figure 5 The bill acceptor pulls the bill in and examines it for authenticity or validates it before pulling it all the way into the machine The AC400B s bill validator is stackerless so upon acceptance the bill is ejected into a pile that will harmlessly form on top of the battery At this point the validator communicates to the Logic Board via electronic pulses the denomination of bill that was accepted The Logic Board reads the pulses credits the money to its runni
