Description
Possible Cause/Suggested Fix
APS Sel CAN Bus Off
APS (Absolute Position
System) CAN Bus
Comm Off Fault
• From the LCD user interface, select the Diagnostic menu
and then the Sel CAN Com Status menu. The Rx Error Cnt
should be zero and the Rx Data Cnt should be incrementing.
If the selector board is not communicating it will show with
the online status equal to 0. If the Rx Error Cnt is not zero,
there is most likely a connection problem from the COP to
the Main I/O board.
• Verify that the APS Camera CAT-6 Ethernet cable is
connected to the Ethernet jack on the COP board.
• Check the terminal connection for the twisted pair wires.
Verify that CANH and CANL on the 1134 COP board are
wired to CANH and CANL on the 1121 Main I/O board
respectively.
• Make sure the CAT-6 cable is not run in parallel with any
high voltage wires.
• Noise on the CAN Bus, verify that the shield wire is
connected according to the job print.
