Troubleshooting Guide
Laurel
DigiMax
3 & 5 Column Vending Machines
(
Red circuit board
)
Use this guide in conjunction with the instruction manual located in the machine or online at
. The pictures and parts number identifications in the manual will be
used here.
When calling Laurel for help (888-528-7358) we will need the machine model #, serial # and
manufacture date which is on a decal inside the cabinet, on the left side near the bottom.
Normal Operation:
The scrolling, red LED display has different styles of display:
1. If all the selections are programmed for the same price the LED display will scroll
Pay
$1.00 Insert Coins
(price amount may vary according to your settings)
2. If you have different prices for your products the LED display will scroll
Insert Coins
3. If there is a credit card swiper installed the display will scroll
Insert Coins or Credit Card
The vend price of any selection button can be viewed by simply pressing the PUSH button on
the switch pad (#899-20) at any time, the price will appear on the LED display for 2 seconds and
then return to normal scrolling.
A quarter inserted in the machine will have an audible ‘beep’ and register
$0.25
on the LED
display. Additional quarters will add upwards on the display. All quarters will pass down into
the coin cup (#899-B19) and be held in the cup until there is successful operation of the column
vend motor (#899-A42) which drops the shelf to vend the product. At that point then the coin
cup motor runs to drop the quarters down into the coin box below.
Underpay & Overpay:
The machine is designed for exact pay and does not make change, this enables a much simpler
design with less complex parts to maintain. For example, if 1 quarter is inserted and a selection
button is pushed for a $0.50 item the coin cup will run and return the quarter to the customer
since it is an underpayment.
For overpayment the coin cup will also run and return the inserted coins to the customer if too
much money is inserted for the column button pushed. Also, if the highest price set for the
machine is $1.00, for example, and a customer inserts more than $1.00 then the coin cup
automatically runs to return all coins to the customer, thus not allowing an overpayment.
There is an option in the circuit board programming to allow overpayments, this is discussed
further down in the section titled
Optional Programming Modes.
