B Alarm List
Solution
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 is less
than 80 V, the mains
voltage is not normal; if
the mains voltage exceeds
88 V, the power module
sampling circuit or fuse
may not be working
properly. Replace the faulty
module.
Check the mains.
Verify the cable connections.
1. Secure or connect the
neutral wire to the cabinet
if it is loose or
disconnected.
2. Check that the neutral wire
to the power distribution
system is normal.
Check whether the mains
voltage ranges from 80 V
(excluding 80 V) to 176 V. If
no, the mains monitoring
circuit for the power module
is faulty. Replace the faulty
module.
1. Check the bypass input
voltage or cable
connections with a
multimeter.
2. Check the voltage system
and bypass voltage
thresholds configured on
the LCD.
