SECTION 1: GENERAL INFORMATIONINTRODUCTIONThis manual contains information on installing, operatingand maintaining Coinco's MAG Series bill acceptorsThis manual is intended for owners, route operators andshop-level technicians as a primary source of informationTaking time to read this manual and becomingfamiliar with this information will help you obtain thebest performance from your Coinco bill acceptorMODELSMAG Series bill acceptors are self-contained unitsdesigned to work with existing vending machine interfaces,plus MDB vendors Listed below are some of themodels available:MAG50BMAG52BXMAG50SAMAG bill acceptor, 500 capacitystacker, 110V AC, Bottler interfaceand maskMAG bill acceptor, 500 capacitystacker, 24V DC, Bottler mask, MDBinterface onlyMAG bill acceptor, 500 capacitystacker, 110V AC, Snack interface andmask, Additional length harnessMAG50B bill acceptors are primarily used in cold drinkvendors which use either the electromechanical, electronic,or MDB interface This bill acceptor uses the"bottler" interface, which communicates to the vendorthrough either HIGH LEVEL or MDB communicationMAG52BX supports MDB communication onlyMAG50SA and MAG52SA bill acceptors are primarilyused in either electronic or MDB snack, coffee or foodmachines These bill acceptors use the "snack" interfaceand communicate to the vendor through either PULSE,SERIAL, PARALLEL or MDB communicationFOR YOUR RECORDSA label indicating the model number and serial number isaffixed to the back of the bill acceptor Refer to themodel and serial number whenever you call upon yourCoinco Service Center for information or service Thefirst four digits of the serial number contain the manufacturingdate code which indicates the beginning of thewarranty periodEXAMPLE: Serial number 269900135 First andsecond digits indicate the week of manufacture Thethird and fourth digits indicate the year (the 26th weekof 1999)FEATURES• Modular design• Bill Hold Feature• Center drive belt• Scalloped bill path for wet bill acceptance• State-of-the-art electronic logic system• Switch selectable acceptance of the following bills: $1,$2, $5, $10 and $20• High capacity bill box• Vandal resistant design protects against: saltwater, billpullback, counterfeit bills• Utilizes standard mounting and electrical interfaces• 110 and 24 VAC and 24 VDC Multi-Drop Businterfaces available• High impact, non-corrosive plastic construction• Easily accessible bill path• Self-diagnostics communicated via status light• Standard/High Level security switch• Switch selectable acceptance of bills face up, in one orboth directions• Optional hasp for locking bill box• Manufactured and supported by Coinco• Made in the USAAFTER UNPACKINGAfter unpacking the unit, inspect it for any possibleshipping damage If the unit is damaged, notify theshipping company immediately Only the co-signee (theperson or company receiving the unit) can file a claimagainst the carrier for shipping damage We recommendthat you retain the original carton and packing materialsto reuse if you need to transport or ship your acceptor inthe futureIf the bill acceptor is being stored or used as a spare,always keep it in its shipping carton when not in useThis will keep it clean and offer the best protection forthe unit4

SECTION 1: GENERAL INFORMATIONMAIN LOGIC BOARD ASSEMBLYThe main logic board contains the microprocessor whichcontrols all the functions of the bill acceptor based oninformation from the vending machine, coin mechanismand various bill acceptor sensorsAlso contained on the main logic board is the powersupply which receives its primary voltage from thevending machine For 117VAC units, the primary ACvoltage is routed to the transformer in the bill acceptorwhere it is reduced to 24VAC This 24VAC is thenrouted back to the main logic board where it is rectifiedand filtered for logic board operation For 24VAC and 24VDC (MDB) units, no transformer is needed Theprimary voltage is rectified and filtered on the main logicboardSPECIFICATIONSPower RequirementsMAG50B, MAG50SA — 117V AC95 to 130 VAC, 60 Hz02 Amp max standby075 Amp max operatingMAG52B, MAG52SA — 24V AC20 to 32 VAC, 60 Hz02 Amp average standby25 Amp average operatingMAG52BX--24V DC22 to 45 VDC02 Amp average standby25 Amp average operatingOperating Temperature0°F to 150°F-18°C to 65°CStorage Temperature-22°F to 165°F-30°C to 74°CRelative Humidity5% to 95% non-condensingPhysical Weight in Shipping Carton57 pounds - 117VAC4 pounds - 24VACPhysical DimensionsMAG30B MAG50B MAG70BHeight 1116 inches 1116 inches 1116 inchesfrom top of bill box to bottom of mounting plateWidth 526 inches 526 inches 526 inchesfrom logic board cover to mounting plateDepth 429 inches 492 inches 617 inchesfrom mounting plate to back of stacker5
