1 Input MCB Trip The system AC input MCB tripped Critical None
2 SPD Fault The SPD circuit is faulty Critical 8
Only in a system with
AC sampling board
3 Digit Input Fault
The alarm name is user defined, not
longer than 10 characters. The
high/low level alarm can be set in the
alarm mode.
No alarm None
In a system with AC
sampling board, you can
name 2 routes; in a
system without AC
sampling, you can name
8 routes
4 DC/DC Failure Including DC/DC converter fault Critical None
5 AC Over Volt
The system AC input voltage is
higher than the set value of
parameter “OverVolt”
Critical None Over-voltage alarm
6 Ph-X Volt Low
The system AC input voltage is lower
than the set value of parameter
“LowVolt”
Critical None Under-voltage alarm
7 Phase failure
The AC input voltage of the power
system is lower than 80V
Critical None
8 Power Failure
In double-AC auto-switchover
system:
1. All AC voltage inputs are lower
than 80V.
2. Both AC inputs 1 and 2 are
broken.
In single AC input system or
double-AC manual-switchover
system, the AC voltage of all
rectifiers are lower than 80V
