Portable Test Unit (Ptu); Description - Komatsu 830E Shop Manual

DESCRIPTION

The minimum requirements for the laptop computer to
be used for the PTU are as follows:
•
IBM compatible, portable PC
•
20 megabyte hard disk drive
•
3.5" floppy diskette drive
•
2 megabytes RAM
•
Serial Port & cable
A larger capacity hard disk, additional RAM, and a
spare battery pack are desirable.
Control software provided by GE or Komatsu on a 3.5"
floppy disk must be transferred to the PTU hard disk
drive prior to transferring the Control Program to the
truck.
All adjustments, setup procedures and diagnostic trou-
bleshooting of the truck's control system can be made
via this PTU. Most of the procedures are menu driven,
with function screens provided as part of the operating
software. Figure 2-2. illustrates the "Main Menu" which
appears when the software program opens. Figure 2-3
illustrates the "menu tree" showing the various screen
menus available from the main menu and the path
required to reach the next level sub-menu.
Sample PTU screens illustrated on the following pages
show menus and data screens as they appear in the
Statex III Enhanced Version 1.00, April 2001 software
release. Minor differences may appear on the Statex III
Version 14.00, April 2000 PTU screens. Earlier and
later versions of the software may differ.
Note: Statex III Enhanced Version 1.00 software must
be used if the truck was equipped originally with a
17FB144 CPU card or if the original 17FB101 card was
replaced with a 17FB144 card. Version 14 should be
used if the truck is equipped with a 17FB101 CPU card.
The information that follows is presented in the
sequence that would most likely be used at a mine site
that was receiving new Statex III trucks or a mine that
was updating software from previous release versions.
It is assumed the technician is familiar with the basic
operation of a laptop computer.

OPERATIONAL HINTS
Here are a few things to remember about the use of the
PTU and software:
•
Some instructions in this manual call for the
user to type certain operating commands.
These commands are shown in a typewriter
style type font within quotation marks to indicate
the characters to be typed from the keyboard.
The operating commands should be typed in
lower case letters. Do not type the quotation
marks when entering commands on the PTU.
(Refer to the chart below.) Other operations
require pressing an individual key on the key-
board; these keys are shown in square brack-
ets. For example, if an operation requires
pressing the key labelled "Enter", it will be
shown as [ENTER]. Keys shown as [F1]
through [F10] refer to the Function keys across
the top of the keyboard. Note that many porta-
ble computers require pressing another key
(usually labelled "Fn") in conjunction with each
Function key.
•
Keep the PTU plugged into its charger when
possible to maintain a full charge on the battery.
•
There is an indicator light on the PTU which,
when lit, indicates low battery power. If this light
should come on while using the PTU, continue
until you reach a convenient break point. Return
to the main menu and turn off the PTU. Then,
replace the battery with a spare and continue.
•
If a spare battery pack is available, switch the
PTU battery occasionally to ensure that both
batteries are kept fully charged. Battery life can
be extended by fully discharging and recharging
every 3 months.
