How to configure the dual AC input switching threshold on the NetSure 7100 A61-S2?

You can adjust thresholds via the front panel Advanced Controller LCD menu or Web GUI by navigating to 'AC Power -> ATS Settings' to modify over-voltage, under-voltage, and frequency parameters based on local grid conditions. For bench test verification, pinout diagrams, and custom warranty terms, contact our engineering desk via WhatsApp +86 17621197907.

How to manually or automatically restore power after secondary LVD (LLVD and BLVD) is triggered?

The system supports automatic restoration once utility power returns or battery voltage recharges above the configured safety threshold. In manual mode, operator confirmation via monitoring GUI is required. For bench test verification, pinout diagrams, and custom warranty terms, contact our engineering desk via WhatsApp +86 17621197907.

How to troubleshoot internal busbar and circuit breaker overheating alarms on the distribution cabinet?

First identify the faulted breaker via monitoring and use an infrared thermometer. Power down and check if busbar connection bolts meet torque specifications to eliminate loose contacts.
