Power grid exception: The
power grid frequency is lower
than the frequency required in
the local standard.
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 frequency is
within the allowed range. If
not, contact the local power
operator. If yes, modify the
power grid underfrequency
protection threshold after
obtaining the consent of the
local power operator.

Frequency
Unstable
Major Cause ID = 1
Power grid exception: The
actual grid frequency change
rate does not comply with the
local power grid standard.
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 frequency is
within the allowed range. If
not, contact the local power
operator.
2039 AC
Overcurrent
Major Cause ID = 1
The grid experiences a
dramatic voltage drop or is
short-circuited. As a result, the
transient AC current of the
device exceeds the upper
threshold and triggers
protection.
1. The device detects its
external working conditions
in real time. After the fault
is rectied, the device
automatically recovers.
2. If the alarm occurs
frequently and
aects the
operation of the power
plant, check whether AC
short circuit exists. If the
fault persists, contact your
dealer or technical support.
