3.5. FAULT REPORTING, continued
The transaction counter has a range of 00000 - 59999 and then rolls over to 00001. Each
side of the dispenser has a transaction counter. When Option 01 is entered the current trans-
action number for side 1 is shown in the Sale Money Display. The value of side 2 transac-
tion counter (if two fueling points) is shown in the Sale Volume Display. See Figure 3-4.
for an example. Pushing the Totals button while the transaction values are displayed causes
entry into the Fault Code History Display Mode. See Figure 3-5. for an example. As shown
the transaction number is displayed for each side along with the fault code for that transac-
tion number. The first fault code displayed is the most recent.
Pushing the Totals button cycles through the fault codes. This mode will display the last 16
fault codes detected by the dispenser’s computer since the last RAM clear (not 16 per side
but 16 total for that computer).
In order to reset the dispenser after an Error or Hydraulic fault, the initial problem must be
corrected and power to the computer cycled or Option 99 is entered. Until these conditions
are satisfied the fault code will continue to be displayed at the end of the reset cycle.
