TROUBLESHOOTING & MAINTENANCE
7.1
Condition Overview
General error conditions that occur in the “
machine
” will be shown on the user LCD display as soon
as the “Menu Mode” is accessed. These errors along with other “events” can be viewed or printed
from the Event Report menu. These are general error conditions that were encountered by the
machine
. A complete list of these errors is listed in the Machine Troubleshooting Chart found in
section
12.1.5
.
Some modules included in the machine can also report more details pertaining to their own error
condition. The reporting methods used to identify these are referred to as “Flash Codes” because they
use a series of LED flashes to provide troubleshooting information. As an example, a complete list of
dispenser error “flash codes” is listed in the Flash Codes & Troubleshooting Chart in section
12.1.8
of this manual. The MEI bill acceptor used in the Guardian XP has a decal on the bill cassette, which
includes a list of flash codes for that device.
Machine error conditions can either be “Soft Errors” which are errors that DO NOT result in the
machine going out of service, or “Hard Errors” which are errors that DO cause the machine to be
placed out of service. “Help” for some error conditions can be accessed much the same way as
accessing the Help for Setting or Report menu items. To view the help information, press the “ENT”
(same as Help) button on the user keypad while viewing the error condition. If you do not see the
troubleshooting help information on the display after pressing the “ENT” (Help) button then
additional help information has not been included for the error condition you are troubleshooting.
7.2
Viewing Machine Errors
To view a machine error you must first enter the “Main Menu” mode by pressing the two red buttons
on the main control module and holding them for a minimum of 3 seconds. Upon releasing the
buttons you will see the most recent error displayed on the User Display of the machine. If multiple
errors exist, you can view the next one by pressing the Right Arrow button (selection 2 button).
Repeat this until you see the “Main Menu” screen.
7.3
Resetting Machine Error Conditions
Error conditions can be cleared by first resolving whatever
caused the error,
and then pressing the
button labeled “RESET” on the main control module. To determine the
error cause,
you must first
identify the device that is in error. When entering the Main Menu mode, the device in error is shown
on the top line of the display. If there are multiple devices of the same type, it may be necessary to
view the flash code LED on each of the devices to determine which one caused the error.
7.4
Configuration Report
The configuration menu is a powerful tool that can be used in diagnosing the root of most failures.
The main control module of the Guardian XP communicates to all other components connected to it
through serial communication. By simply viewing the Configuration Menu, you will be able to
determine what components are available in the system, including information on the component type
and software revision. Other information such as the Internet IP address for machines with an
optional IPTran for high-speed credit card transactions and third party card systems can be viewed, as
well as a POS systems if applicable.
