faulty.
1. Check whether cables to mains
are disconnected, loose, or
incorrectly connected.
2. If cable connections are correct,
measure the mains voltage with
a multimeter. If the mains
voltage exceeds 280 V, the
mains input is not normal; if the
mains voltage is less than 272
V, the sampling circuit of the
power module is not normal.
Replace the faulty module.

the mains voltage exceeds 88 V,
the power module sampling
circuit or fuse may not be
working properly. Replace the
