b). To prevent accidental partial resetting, button no. B needs to be kept pressed for 3-4 seconds, till the display shows
r-ld, confirming the partial resetting has been executed.

zero value, then button no. A needs to be kept pressed for 3-4 seconds.
A long beep with
ALL r-ld
, on display will confirm that the resetting/reloading of all the 5 Negative Counters to their
preset value has taken place
Note
:
a)
To avoid accidental reloading of all the neg. counters, button no. A (fig.2) needs to be pressed for 3-4 seconds, till
the display shows ALL r-ld, thereby confirming the reloading of all Negative Counters.
b)
It is desirable to indicate on an Instruction label on the front of the machine that the customer should first press the
selection button on the machine to check product availability before inserting money into the coin validator.
If money is first inserted into the validator and all the shelf selections are empty i.e. ‘Sold Out’
and then a selection is
made, then the display will show ‘Sold Out’ and the money will not be returned.
Test Sequence
The VMC constantly tests the operation of the machine, the data stored and the peripherals attached. Every .01
seconds, a self-test analysis is done to verify correct operation of the machine. Further tests are done on Power Up,
Button Press, Coin Insertion and entering/exiting Service mode. These tests will generate the relevant fault code as
necessary. However, it is possible to do a thorough analysis through Service Code AP, which will individually test each
motor as well as escrows and other related functions. This is useful to re-align any jammed motors.
