8 Alarm Reference
Suggestion
1. If the alarm occurs
occasionally, the power grid
may be abnormal
temporarily. The device
automatically recovers after
detecting that the power
grid becomes normal.
2. If the alarm occurs
frequently, check whether
the power grid voltage is
within the normal range. If
not, contact the local power
operator.
3. If the fault persists for a
long time, check the
connection of the AC cable.
4. If the AC cable is correctly
connected and the alarm
persists and affects the
operation of the plant,
contact the local power
operator.
