8.5 Replacing CPU Boards
Replacing a board is best done by modifying a stored system configuration that was uploaded from the system’s
primary CPU board via Revolution III or the Virtui
2 Configuration Utility.
8.5.1 Replacing the Primary CPU Board
1. Load the stored configuration for the system into the RLWS configuration utility.
2. Remove power from the iQUBE
2 system.
3. Remove the primary CPU board to be replaced. Label the load cell cables to ensure the load cell connectors
will be plugged into the same connectors on the replacement CPU.
4. Install the new CPU board by connecting the system exactly as it was with the old board.
5. Connect power to the system and place it in SETUP mode by moving SW1 to the CFG position (see Figure
on page 6).
6. Connect iQUBE 2 ’s primary CPU using the system configuration utility.
7. Manually type in the new board ID (see Figure on page 6) or delete the existing board ID and leave it empty
if you intend to upload the new board ID via Revolution III.
8. Download the stored configuration file to the iQUBE 2 , then return SW1 to the OFF position.
8.5.2 Replacing a Secondary CPU board
1. Load the stored configuration for the system into the RLWS configuration utility.
2. Remove power from the iQUBE
2 system.
3. Remove the secondary CPU board to be replaced. Label the load cell cables to ensure the load cell connectors
will be plugged into the same connectors on the replacement CPU.
4. Install the new CPU board by connecting the system exactly as it was with the old board.
5. Connect power to the system and place it in SETUP mode by moving SW1 to the CFG position (see Figure
on page 6).
6. Connect iQUBE 2 ’s primary CPU using the system configuration utility.
7. In the configuration utility, find the ID of the secondary board that was replaced in the list of Secondary IDs.
8. Highlight the field that contains the old 8-digit hexadecimal ID and type the 8-digit hexadecimal ID of the
new board (not case-sensitive).
9. Download the stored configuration file to the iQUBE 2 , then place the system in WEIGH mode by moving
SW1 to the OFF position.
8.6 Troubleshooting
The following section provides information to assist for troubleshooting or repairing the iQUBE 2 .
Materials needed to accomplish these steps are:
• 920i
• Revolution III or Virtui
2 Configuration Utility loaded onto a PC
• Digital voltmeter
8.6.1 General Steps
To determine that the iQUBE 2 has power, check LED HB1 on the core module and LEDs for the load cells
assigned on each connector board (see Figure 2-1 on page 6).
Use a voltmeter to measure the voltage at connector J6. Pin 1 should show at least 6 volts.
Verify communication LED5 on the core module is flashing.
If using Virtui 2 , if the iQUBE 2 CPU board’s power and LEDs are all properly lit, launch the Diagnostic Monitor
from the Virtui 2 Configuration Utility Tools menu to run diagnostic tests and view errors. Launch the Cell Monitor
from the Tools menu to view the outputs of each load cell.
For Revolution III applications, connect the PC to connector J7. After connecting, upload the iQUBE 2 configura-
tion to the PC to verify the proper configuration is still loaded. If not, download the correct configuration to the
iQUBE
2 and recalibrate. Also verify that the iQUBE 2 software is the latest version. See Section 3.3 on page 30 for
information on connecting to iQUBE 2 and downloading configuration.
If the configuration looks good, check the outputs of each load cell. Cell outputs should change when a weight on
top of each cell or when the load cell cable is disconnected.
