Payload Meter Iii - Komatsu 930E-4SE Operation & Maintenance Manual

OM6009 2/10
INTRODUCTION
Payload Meter III (PLMIII) measures, displays and
records the weight of material being carried by an off-
highway truck. The system generally consists of a
payload meter, a gauge display, deck-mounted lights,
and sensors. The primary sensors are four
suspension pressures and an inclinometer. Other
inputs include a body up signal, brake lock signal,
and speed.
Data Summary
5208 haul cycles can be stored in memory. The
following information is recorded for each haul cycle:
• Payload
• Operator ID number (0000-9999)
• Distance traveled loaded and empty
• The amount of time spent empty run/stop,
loading, loaded run/stop, and dumping
• Maximum speed loaded and empty with time of
day
• Average speed loaded and empty
• Empty carry-back load
• Haul-cycle, loading, dumping start time of day.
• Peak positive and peak negative frame torque
with time of day
• Peak sprung load with time of day
• Tire ton-mph for each front and average per rear
tires
The payload meter stores lifetime data that cannot be
erased. This data includes:
• Top 5 maximum payloads and time stamps.
• Top 5 positive and negative frame torque and
time stamps
• Top 5 maximum speeds and time stamps

Data Gathering
Windows 95/98/NT software
download, store and view payload and fault
information. The PC software will download an entire
truck fleet into one Paradox database file. Users can
query the database by date, time, truck type and
truck number to produce reports, graphs and export
the data. The software can export the data in '.CSV'
format that can be easily imported into most
spreadsheet applications. The Windows software is
not compatible with the Payload Meter II system.
It is important that each payload meter be configured
for each truck using the PC software. The information
for frame serial number and truck number is used by
the database program to organize the payload data.
In addition, the payload meter must be configured to
make calculations for the proper truck model.
Improper configuration can lead to data loss and
inaccurate payload calculations.
