8. Inspection and Maintenance
The main electrical components of the MiniPCIe interface CAN card are
semiconductor components. Although it has a long life, it may also age quickly under
inappropriate conditions. Periodic inspections should be carried out to ensure that the
required conditions are maintained. It is recommended to check at least once every 6
months to a year. Under unfavorable environmental conditions, more frequent inspections
should be carried out.
If you encounter a problem during the maintenance, see Table 8.1 to identify the fault
cause. If the fault persists, contact Guangzhou ZLG Electronics Co., Ltd.
