Title: Improved Work Platform Mode Leveling Functionality Applicable Products:

Model Serial Number Range

TH414 TBZ00100 – UP (platform ready) Description: New universal ground module software is available for all platform ready equipped units to enlarge the allowable machine positioning envelope from the current 1º to 3º when in platform mode. The maximum boom angle changes to 58º instead of 60º. Enlargement of the slope angle improves set up of the platform machines on rough terrain. In combination with the improved universal ground module software, updated cabin display software and platform control module software are available. The new display software improves the operators ability to position the machine accurately. Software Releases: The following software releases are now available through the CAT Alliance Website:

• Universal Ground Module Software P3.2 (1001098643vP3_2.exe) • Display Software 3A (4170097_v13-A8.exe) • Display Software 3C (4170097_v13-C8.exe) • Platform Control Module Software P3.0 (1001097078vP3_0.exe)

Refer to attachment 1 for Software Installation Instructions. Refer to attachment 2 for Improved Display Overview.

SOFTWARE UPDATE PROCEDURE STEP 1: REPROGRAMMING UNIVERSAL GROUND MODULE

a. Ensure that the platform is connected to the machine via the electrical harness of the platform (Illustration 1).

Illustration 1 b. Connect the Communication Cable (P/N 330-5253) to machine connector on the

power distribution board (Illustration 2) and to the serial port of the laptop. If no serial is port available on laptop use the USB Serial adapter.

Illustration 2 c. Turn on computer

d. Turn machine ignition key to “ON” position.

e. Open software application (Illustration 3). Double click on the yellow icon, the reprogramming tool will open.

Illustration 3

f. Start reprogramming tool by clicking “Program CAT TH series Telehandler Version P3.2”.

g. The program will ask for an overwrite confirmation, click on “Yes” (Illustration 4).

Illustration 4 Note: During reprogramming, you will hear a continuous beep of the machine.

h. When the software update was finalized successfully, “Programming success at hh:mm:ss (x sec)” will be shown at the bottom of the reprogramming tool.

i. After completing the programming, turn the machine ignition key to the “OFF” position, wait for 5 seconds and turn the ignition key back to the “ON” position again.

STEP 2: REPROGRAMMING CABIN DISPLAY

a. Open software application (illustration 5 & 6). Double click on the yellow icon, the reprogramming tool will open.

Illustration 5 Illustration 6

Note: only one of the two display software will work on each machine, due to certain parameters in the original display software. If “Cabin Display Update – 3A.exe” software file is not working (see illustration 7 for error message), turn ignition key switch “OFF”, close the reprogramming tool 3A, turn the ignition key switch “ON” and open the software file “Cabin Display Update-3C”.

b. When the software update is finalized successfully, “Programming success at hh:mm:ss (x sec)” (Illustration 8) will be shown at the bottom of the reprogramming tool.

Illustration 8 Note: when the reprogramming is finished, you will hear a continuous beep of the machine.

c. After completing the programming, turn the machine ignition key to the “OFF” position, wait for 5 seconds and turn the ignition key back to the “ON” position again.

STEP 3: REPROGRAMMING PLATFORM CONTROL MODULE

a. Turn machine ignition key to “ON” position.

b. Open software application (illustration 9). Double click on the yellow icon, the reprogramming tool will open.

Illustration 9 c. Start reprogramming tool by clicking “Program Bradford Platform Version P3.0”.

d. The program will ask for an overwrite confirmation, click on “Yes” (illustration 10).

Illustration 10 Note: During reprogramming, you will hear a continuously beep of the machine.

e. When the software update was finalized successfully, “Programming success at

hh:mm:ss (x sec)” will be shown at the bottom of the reprogramming tool.

f. After completing the programming, turn the machine ignition key to the “OFF” position, wait for 5 seconds and turn the ignition key back to the “ON” position again.

g. Disconnect communication cable (P/N 330-5253) from the Power Distribution

Board.

h. Perform a complete function check in accordance with the Operation and Maintenance Manual, the unit may be returned to service once proper operation is confirmed.

NEW LAYOUT – PLATFORM CONNECTED

Note: minimum requirement to change to platform mode is both level gauges (indicated by five horizontal and five vertical squares) need to be in the third box with a white dot in

the middle (reference “a” above). If the machine is completely level, the third box on both level gauges will be fully black (reference “b”).

When the stabilizer is positioned properly (correct position and enough pressure),

the arrow and the bottom plate of the stabilizer will be full black instead of white (reference “c”).
