| The
DL-390 series dispenser, along with the D2400 console system
were modular designs long before Gilbarco introduced the concept
into its pump line. The DL-390 series originated about 5 years
earlier than the Gilbarco modular pumps but was introduced
with much less fanfare. These dispensers have weathered the
upgrade storm and are still very much in use. They are able
to be upgraded to card readers and Wayne-Vac.
The
DL-390 system comprises one computer base, a solenoid drive
board and main display per side. It also uses one PPU board
per hose.
When
it was introduced, the modular Decade 2400 system had about
6 of its 8 slots reserved for future upgrade. These are
now being used 15 years later with the Wayne Plus and Card
readers.
Wayne
blending dispensers were originated with the 511 for Sunoco
about 40 years ago. The 511 electronic retrofit (FL84) was
the springboard for Wayne electronic
DL-395 blenders. The main display in a 395 blender is the
same as a DL-390. Otherwise, all boards are different. They
each have similar names and functions (i.e. there is a computer
base, solenoid drive and PPU display in both types) but
they do not interchange.

Production Options
This
product line has been upgraded in many ways during its lifetime,
among them are:
1)
The customer display has been enlarged and other ongoing
internal electronic upgrades have been done.
2) The handle switch system has been changed from a lever
type “flip-to-start" to a more durable “slide-to-start"
system as shown in the illustration. (Slide-to-start assemblies
are frequently retrofit on “flip” dispensers,
however, so absence of the “flip” handle does
not necessarily indicate a later production unit.)
3) The internal hydraulics have been simplified. “Old
Style” hydraulics have external solenoid valves and
exposed copper tubing in the lower hydraulics. “New
Style” hydraulics have in-line valving systems. Additionally
and very important: “New Style" dispensers are
all piped for vapor recovery. Several cash/credit options
are used on DL-390s, some of which are proprietary to major
oil companies and
involve special dial faces.
Retrofit
Options
The
MGD-series can be updated to card readers by use of Vista
upgrade heads.
Suction
Pumps and Blenders
Because
of Wayne’s long standing relationship with Sun Oil
Company, they have always offered blending dispensers. These
are quite common in the marketplace and well proven.
Suction
pumps are theoretically available in new production, but
rarely seen.
Console
Compatibility
Decade
2400 pump controller with or without the Decade 1000 cash
register, Wayne “Plus.” Third party POS systems
can be interfaced through the “PIB” box.
Tech
Tips
The
aluminum pipes running vertically in the sides of the dispenser
can wear through by rubbing against each other. Wayne has
corrected this problem in later production units by adding
stabilizing clamps in the side runways. This clamp is available
and recommended as a retrofit item.
Early
model piping used compression-type “Dresser” connectors,
which were prone to leaking. In later units, these have
been replaced with piping welded into mating flange connections.
Comments/Usage
Recommendation
Wayne
dispensers are a good choice for almost any application.
The meters are generally very reliable and, because of Waynes
approach to upgrades, almost any unit can be updated to
the latest electronics (i.e., card reader, etc.) configuration.
Wayne
produced many small variations of each unit, however, so
it is usually necessary to have serial numbers when ordering
parts. Also, it is difficult to match up Wayne units when,
for example, adding an island to an existing station.
