How to Use Diagnostics
Menu Code 0
To enter Diagnostics the manager’s keypad must be connected to the dispenser to place the
dispenser into the manager’s mode. See page 17 for instructions on how to attach the manager’s
keyboard. Make sure the A.C. Reset switch is in the ON position, and the pump handles are all in
the OFF position. These instructions will not be repeated for each Menu Code.
Diagnostic tests have been programmed into the dispenser software to help the operator and service
technician troubleshoot failures of the dispenser. The dispenser can run several levels of self-diagnostic
tests to determine where the failure has occurred. The levels that will be discussed here are:

By performing a diagnostic test, the operator or manager can inform the service technician of the problem
before coming to the site. The service technician can then anticipate which repair parts to bring to the
site.
To enter Diagnostics, follow this procedure:
After the correct number (1 or 2) has been entered for the
side to be viewed, press the 0 button and then the
MODE
button on the keypad. The main display appears as in
figure D-1. The price shows the Side being read.
From this point, any test can be entered by pressing the
number of the test and the
ENTER button. To exit a
diagnostic test, press the CANCEL button.
