26 Installation Gilbarco Interface Unit v2.1
Gasboy CFN Series
To solve this, make the interface forget about the even- numbered pump by clearing its
memory. For the procedure see Erase interface unit memory under Connect and test the
installation, earlier in this chapter.
Site reports wrong fuel or wrong dollar amount
If a transaction or the receipt shows the wrong fuel or an incorrect dollar total, check the pump
firmware version.
If your pump is an Advantage version 70.1, see Advantage version 70.1 firmware in the first
chapter.
If your pump is a Modular MPD-3 version 53.7, see Modular MPD-3 version 53.7 firmware
in the first chapter.
Also refer to other incompatible pump versions in “Incompatible pump firmware releases”
on page 5.
If your pump is of any other type or has any other firmware version, contact Gasboy
Technical Service immediately.
MPDs will pump only zero-quantity transactions
Older (pre-Advantage) MPDs will pump only zero-quantity transactions if they are activated
using grade restrictions. The grade restriction feature is enabled using SW3-5 CLOSED. See
“DIP switch bank 3” on page 16, for more information.
Zero quantity transaction
Pumps activate when START is pressed on POS but the transaction completes as a zero-quantity
when handle is raised on pump.
Make sure you are not sending too large a money limit. Count the digits, including any
fractional digits. Five-digit money pumps must have a money limit of five digits or less. Six-digit
pumps accept money limits to six digits or less. In either case, the leading three digits of the
money limit must be less than “995” and should not be “980” or “981” for five-digit money
pumps.
Make sure interface SW3-6 agrees with the money digit setting for the pumps: OPEN for
pumps configured for five-digit money, CLOSED for pumps that have six-digit money. All
pumps on an interface must be configured the same way.
Unassigned Transactions
Every reader configuration must have a “select pump” program step prior to the “activate pump”
step. Failure to include the select pump step will cause warnings about unassigned transactions,
with pumps becoming disabled after the transaction.
