USA MAV500/MKVI Service Manual
Security
For security reasons, both the Stacker Access Door and the Cash Box itself can be
equipped with high-security locks.
The status of the belly panel door is monitored by the machine firmware. If this link
is broken, the machine will lock up and display the error message:
Door Open – Bill Acceptor
If the Cash Box is removed, the error message
and the alarm sound is played through the speakers.
Both of these exceptions are reported to the on-line system, if installed.
Mechanics and Transport
The Bill Acceptor assembly consists of the Acceptor and Transport. It slides into the
WBA Frame, where it is securely latched in place. The Cash Box slides into position
and latches into the WBA Frame just below the Transport.
Transport
The Transport assembly houses the main logic assembly; two drive motors,
associated gears, belts and opto-interrupters.
The main logic assembly provides all of the control functions for the acceptor.
It may be configured with either FLASH (
memory.
One drive motor provides motive power to the drive belts, which transport the bills or
coupons through the Acceptor and into the Cash Box. The other drive motor links
(via a gear train) to the stacker mechanism in the Cash Box.
The two upper timing belts are individually tensioned to assure a reliable and straight
feed. The lower timing belt assures transport of the bill or coupon to the entrance of
the Cash Box.
Several levers and optic sensors assure proper direction of travel and progress into the
Cash Box
A connector and mounting provisions are provided for the Acceptor, which mounts
into the Transport assembly.
Two opto-interrupters mounted at the rear of the Transport monitor the presence of
the Cash Box and bill pusher activity.
Acceptor
Interchangeable guide rails in the Acceptor allow proper sizing for currency from a
variety of countries. Acceptable bill widths are 66, 70, 75 and 80 mm. Acceptable
lengths are determined in the software.
