1X
A bad connection between the FIB and the
fi
rst VIB will deny power to the boards, which control valves for
fi
ltration, and top off. On the touchscreen’s diagnostic screen, the VIB’s will be shown as open. On the software
screen, the VIB’s are visible. The software check is on the P-Bus.
2X
A bad or broken connection between VIB’s will deny power to the actuators downstream from the break. Down-
stream valves won’t open. On the diagnostic screen, valves will be shown as open. On the software screen, the
VIB’s will be visible.
3X
DC voltage from the FIB
fl
ows through the VIB to a gas fryer’s oil is back circuit. A break here can cause the
fryer not to heat. Power to the OIB’s relay is denied, which prevents 24VAC from reaching the gas valve. This
break will kill visibility of the VIB’s on the software screen.

The end of line resistors establish the two ends of the CAN bus and absorb stray data. A missing resistor in
the FIB box will cause errors on the network’s messages. Some network communication issues can be related
to the communication board, or SUI, that’s in the FIB box. If the end of line resister is plugged into the SUI,
the resistor can be moved to the FIB’s CAN plug, J3 or J4, and the SUI unplugged. If the end-of-line resistor
is built-in to the SUI, a separate end-of-line resister must be plugged into J3 or J4 on the FIB before removing
the SUI. Without an end-of-line resistor, power can be removed from the SUI with it otherwise left in place to
determine if the cause is SUI-related.
5X
A bad CAN issue here will cause the left UI to see everything but the FIB. The right will see everything but the
OQS, the component with the end-of-line resistor on the other side of the circuit. The mixed view on the con-
trollers is the hint the issue is between the SIB’s.
