SECTION 1: GENERAL INFORMATION
MAIN LOGIC BOARD ASSEMBLY
The main logic board contains the microprocessor which
controls all the functions of the bill acceptor based on
information from the vending machine, coin mechanism
and various bill acceptor sensors.
Also contained on the main logic board is the power
supply which receives its primary voltage from the
vending machine. For 117VAC units, the primary AC
voltage is routed to the transformer in the bill acceptor
where it is reduced to 24VAC. This 24VAC is then
routed back to the main logic board where it is rectified
and filtered for logic board operation. For 24VAC and 24
VDC (MDB) units, no transformer is needed. The
primary voltage is rectified and filtered on the main logic
board.
