1. Short circuit fault alarm indication: The short-circuit sensor detects the current of the line during operation. When the current reaches or exceeds the setting value of the short-circuit current when the line has a short-circuit fault, the short-circuit sensor sends an alarm signal to the host through the wire/fiber, and the host receives it. After this signal, a corresponding alarm indication signal is generated.
2. Earth fault alarm indication: The earth sensor detects the zero-sequence current of the line during operation. When the grounding current reaches or exceeds the setting value of the grounding current when the grounding fault occurs, the grounding sensor sends an alarm signal to the host through the wire/fiber. After receiving the signal, the host generates a corresponding alarm indication signal.
3. Automatic reset: When the indicator signals an alarm, if there is no manual reset, the indicator can be automatically reset after the set time.
4. Manual reset: When the indicator generates an alarm, the alarm can be released by pressing the “Reset/Test” button on the indicator panel of the indicator for 2 seconds.
5. Test: The indicator can be self-tested.
