Gasboy Gilbarco Interface Unit - Manual (Page 12)

internally. Since the hose is not known before fuel is pumped, price is not known, so a dollar
limit cannot be calculated from a volume limit.
Large gallon limits
If the activation dollar limit, calculated as activation price times gallons, exceeds $994, the pump
may not activate correctly. Sites that use Highlines with various presets, card limits, limitations,
and so on, in gallons, have encountered this error condition shortly after price changes. The
remedy here is to use a smaller gallon limit, so that the limit times the price gives less than $999
pumped.
Site Controller II version 1.0 may also experience trouble at smaller limits, usually larger
than $500. Generally this is seen as sudden inability to activate pumps after a price increase. A
PRINT DIAGNOSTICS command shows error counters NB4 incrementing several times per
failed transaction. The remedy is to use smaller limits, or upgrade to Site Controller version 2.0.
Product restriction on multiple hose or fuel units
Product restriction can be enforced when using newer Gilbarco multi-hose or multi-fuel units. If
you cannot now use product restriction on your Gilbarco MPDs, see if you can upgrade your
Gilbarco pumps.
For Gilbarco Highline pumps, product restriction can be enforced, because there is only one
product on a pump.
Volume display at Check Point or Profit Point
Volume to be pumped and price are not shown by Check Points or Profit Points at the time of a
preset or a prepay on an MPD.
Only the ongoing dollar amount is available from Gilbarco pumps. Even this is unavailable
from a few very old pumps. An ongoing transaction viewed on a Check Point or Profit Point will
always show zero volume.
Advantage version 70.1 firmware
Gasboy equipment is partially incompatible with Advantage version 70.1 firmware. Replace any
Advantage version 70.1 firmware chips with current versions. Failure to do so may cause
unexpected results when operating with multiple price levels.
MPD-2
The only Gilbarco Electronic pump that does not interface to the Site Controller II is the Gilbarco
MPD-2.
MPD Pro Blender
The Site Controller I does not interface to the MPD Pro Blender or any Gilbarco Cash/Credit
pumps.
Modular MPD-3 version 53.7 firmware
Gasboy equipment is partially incompatible with Gilbarco Modular MPD-3 version 53.7
firmware. No upgrade is available for Modular version 53.7 firmware. The problem must be
worked around.
• Use price level 1 or 1 and 2, with level 0 set the same as either level 1 or 2.
• Do not use price levels 3, 4, or 5.
• You may use price levels 6 and above.
