Credit acceptance will be disabled when the accumulated credit equals or exceeds the highest
priced item. Cash box coins and bills are enabled on an individual basis according to the
inventory coins available. Cash box coins and bills will be enabled if the coinage currently held in
the changer's inventory tubes is greater than the coin or bill to be accepted, plus the credit
currently accumulated by the controller.
If all of the configured selections are sold out, credit acceptance will be disabled,
“No Sale” will
flash on the display. If the amount of card credit available exceeds the maximum displayable
credit (dependent on the scale factor), the maximum credit will be displayed.
4.2. Display Activity:
4.2.1. Idle State:
The display will show
“0000” when no switch or vend activity is present.
Program switch must
be ON for coins to be manually ejected from changer tubes.
4.2.2. Switch Echo:
When a selection switch is pressed the display will show the price of the selected item.
4.2.3. Vend Process:
After a switch entry is made the controller will determine if sufficient credit is available and the
status of the selection. If the accumulated credit is greater than or equal to the selection price and
the selection is available, a selection attempt will be made for that selection. If credit is less than
the selection price, the price will be displayed for 3 seconds or until a new selection switch is
pressed. If the sele
ction is not available “No Sale” will flash for 2 seconds along with the "Make
Alternative Selection" LED, or until a new selection is made.
4.2.4. Change Payment:
A least coin payout algorithm will be implemented. Program switch must be ON for coins to be
manually ejected from changer tubes.
4.2.5. Use Correct Change LED:
If the level of the changer's least value coin tube is below the lowest sensor, the "Use Correct
Change" LED will be illuminated continuously.
4.2.6. Power-Up and Reset Initialization:
Following a power-up, or reset condition, the display will test all of the LED segments by displaying
patterns. This will continue until the peripherals and controller have been initialized.
4.3. Internal Vend and Cash Counters:
Following a successful vend, the vend counter will be incremented by one and the cash counter
will be incremented by the price of the selection vended. Counter rollover occurs at 99,999,999
and $999,999.99 respectively. (Note: Test vends are not included in the counter totals.)
4.4. Free Vend:
The "free vend" option allows the customer to free vend items in the machine with no credit input.
The message "FrEE" will be shown on the display and all credit acceptance will be disabled
whenever the "free vend" option is enabled. Disabling the "free vend" option will return the
controller to the normal sales mode.
