9.1.2 Technical Assistance Guide and Questionnaire
If you need to contact Rice Lake for assistance, please use the following section as a guide for troubleshooting or
repair of the
iQUBE .
1. What are the symptoms?
2. Is this a new installation or has the iQUBE been in previous working order?
If new, go to step 3.
If existing, go to step 13.
3. What is the software version for the following:
920i ______________
iQUBE ___________
iRev ______________
Revolution III ______
Very large trim factors Verify that the capacity and sensitivity of each configured load
cell is correct.
Cal-Match failure Try using a test weight with a smaller footprint. Verify
communications.
Calibration shift Possible mechanical problem or corrupted data stored in
iQUBE .
If another device connected to the iQUBE causes this, check
for proper common grounding.
No communication In setup of iQUBE , go to TESTCOM to verify
communications. This step retrieves the serial numbers of the
attached
iQUBE units for verification. Check communication
wiring and switches 5 and 6.
No communication with secondary unit D7 and D8 flash for communications of the primary unit to D5
and D6 of each secondary unit.
Verify connections between J4 of primary unit and J7 of each
of the secondary units.
Verify addresses of each card are correct. Primary = 0
(switches 1–3); Secondary = 1,2, or 3.
Verify 120 Ω resistor is installed across A and B terminals of the
primary (J4 connector) and last secondary unit (J7). See
Figure 2-4 on page 7.
No fiber-optic communication Check for damaged fiber cable. Verify proper connection of
transmit to receive.
Check RS-232 communications to determine if the
communications failure is limited to the fiber communications
board.
No Ethernet communication Verify IP address and connections. Try to connect using Telnet
software.
No analog output Verify configuration is correct for the DAC board. Verify board
is installed correctly. See Section 2.11.4 on page 13.
