Where This Part Is Used
Used in selected XCMG QY-series crane control networks for communication between modules, displays and I/O devices.
Failure Clues and Workshop Check
Bus-off codes, missing nodes or intermittent communication require checking supply, grounds, twisted-pair wiring, termination and external short circuits.
Installation and Handover
Use ESD controls, verify CAN-H/CAN-L and termination resistance, load approved software if required and scan every network node after installation.
