GENERAL INFORMATION
In order to fully utilize the many features of your
vender it is important that you first understand the
options available and procedures for programming the
vending controller unit (control board).
All programming, testing, and service functions are
accomplished by using the keypad in an easy to
follow, display prompted format. There are four modes
of operation for servicing, testing, and setting up your
vender. The modes of operation are accessed by,
opening the service door, and pressing the service
button (blue button on back of display module or the
service button on the control board).
The service button will cycle through each of the four
modes in turn: Service Mode, Test Mode, Set-Up
Mode and Setup Mode 2. In each of these modes,
the “A” key is used to scroll through the available
options/settings within that mode/selection. (Note: In
each of the mode selections, pressing the character
key next to the listed option will take you directly to
that feature - see menu items chart on page 12.), the
“*” key is used as an enter key to select the currently
displayed item/feature, and the “CLR” key is used as a
done or exit key. Closing the service door or pushing
the service door switch will exit the function you are
currently in and place the vender back in service.
