1. System Overview
The LectroCount
3
On-Board Truck
Computer system works in conjunction
with many models of Positive
Displacement Flow Meters. It
accurately measures fuel deliveries,
prints priced receipts, and streamlines
driver record keeping. It can be
equipped with accessories that allow for
temperature volume compensation,
deliveries to be made (net volume), and
delivery information to be exchanged
between the truck computer and an
office computer.
The basic system consists of:
1. Remote Supervisory Control
Box/Remote Electronic Counter
Assembly (RSCB/REC) that is
mounted in place of mechanical
registration equipment on the meter.
2. Supervisory Control Module and
Printer that are mounted in the truck
cab.
3. Lap Pad operator interface.
For trucks equipped with two meters, a
dual meter configuration is available that
allows two RSCB/RECs to be connected
to a single truck computer.
This manual describes the installation of
these components and their
accessories.
Read this entire
installation manual before beginning
the installation to make sure that you
understand the total scope of the
project.
Specific installation
requirements will vary with the model of
truck. Meter type, configuration of
existing metering equipment, selected
options, and the type of fluid being
metered, all influence installation. Make
sure that the RSCB/REC, Electronic
Temperature Volume Compensation kit
(ETVC), pulser, and valves can be
installed in such a manner so as to not
interfere with routine service of the
meter, the strainer, and the meter
compartment door.
The conduit and wiring for the above
components need to be routed with
similar concerns in mind. If a dual meter
system is being installed, the
RSCB/REC, ETVC, pulser, and valve
work must be duplicated for the second
meter.
NOTE: Power, input and output (I/O) wiring must be in accordance with
Class I, Division 2, wiring methods in Article 501-4(b) of the National
Electrical Code, NFPA 70 and in accordance with the authority having
jurisdiction.
WARNING: Explosion Hazard - Substitution of Components May
Impair Suitability for Class I, Division 2.
WARNING: Explosion Hazard - When in Hazardous Locations, Turn
Off Power Before Replacing or Wiring Modules;
WARNING: Explosion Hazard - Do NOT Disconnect Equipment
Unless Power Has Been Switched Off or the Area is
Known to be Non-hazardous.
