The grid voltage is below the lower threshold or the low voltage duration has lasted for more than the value specified by LVRT. |
Suggestion
- If the alarm occurs occasionally, the power grid may be abnormal temporarily. The device automatically recovers after detecting that the power grid becomes normal.
- If the alarm occurs frequently, check whether the power grid voltage is within the allowed range. If not, contact the local power operator. If yes, modify the power grid undervoltage protection threshold after obtaining the consent of the local power operator.
- If the fault persists for a long time, check the connection between the AC switch and power cables.
