CAN Bus Screen
See Figure 3-60 for the following procedure.
The CAN (Controller Area Network) bus diagnostic screen is
for technicians. The screen displays CAN bus packet and
node information, engine status, history status, and boom
status. Any node that is yellow indicates that communication
is lost to that node.
The CAN Bus screen operates on two levels:
Level 1 — Packet number data box highlighted blue
Level 2 — Packet number data box highlighted red
Packet Information
The top row of the screen contains CAN Bus packet number
(26). Enter the desired packet number in the first data box by
using Select buttons.
Packet type (DO) is displayed on top middle data box.
Related node (2) is displayed in top last data box.
Packet contents are displayed in the eight banks under the
row. Packet content and format depends on packet type.
Many packets are not easily interpreted by those other than
factory technical personnel and their content is not
discussed in this publication.
Each individual input/output is assigned a number (identifier)
in the binary system (powers of two). The identifiers of all
inputs/outputs that are ON (active) for each bank are added
for a total of 0 – 255. The number displayed for each bank is
the sum of all identifiers that are ON in that bank. Each
possible ON/OFF combination per bank has a unique total.
To determine the status of an individual digital input or
output, you need to know the CAN packet number (see Table
3-7 and Table 3-8). For example: Drum 1 Brake has a
packet number of CAN26-1-64.
The first part of the Code Number (26) indicates that the
individual input or output is located in packet 26 of the CAN
communications.
The second part of the Code Number (1) indicates the bank
where the individual information is shown on the CAN
screen.
The third part of the Code Number (64) is the item identifier.
Determine status of the individual input/output by checking
the total in bank 1 (255). Find 255 in the numbered column of
Table 3-9
- Bank Identifier Numbers. In the corresponding
row the identifier numbers that are ON in the bank are
shaded. In the above example if 64 is shaded the Drum 1
Brake is ON.
Digital Output Disable Fault
See Figure 3-60 for the following procedure.
The control system is capable of detecting an open or short
circuit in most of the system’s digital outputs. When Fault 84-
Digital Output Disable is shown in fault section of
Information screen, check for DOD fault in packets 36
through 41:
1. Scroll through packet numbers 36 through 41.
2. Banks 1, 2, and 3 of CAN bus screen should display
number 255.
3. If a number less than 255 is displayed in banks 1, 2, and
3, use the Bank Identifier Numbers in Table 3-9
to
determine which bit(s) are off.
4. Use Table 3-6
- Digital Output Disable, to determine
what outputs are not working.
5. Investigate indicated outputs for short to ground, short to
shield or other problem.
Engine Node Status
Engine displays node bus status that is for factory use only.
Communication number should be under 64. See engine
manufacturers manual for engine fault code information.
Crane Status
Two crane status banks on the left side display crane errors.
Crane status banks should display zero.
