Maintenance and replacement precautions
This module is often redundantly configured. Before replacement, it is essential to confirm that the redundant channels are normal to avoid protection malfunctions and unit mis-tripping.
The hardware model and firmware version of spare parts must be consistent with the original card. Inconsistent versions may result in bus communication failure and abnormal channel acquisition.
Shielded twisted-pair cables must be used for analog quantities and communication cables, with the shielding layer grounded at one end of the cabinet to prevent signal drift and data jumps.
After replacement, download the hardware configuration, protection set values, and signal range parameters through Control Builder M software, and verify the channel accuracy and communication status.
Common faults: Channel acquisition drift, communication interruption, fault alarm red light, power loss parameter loss, protection logic mis-trigger.
