faults delay), then low fuel level alarms. if the value is
set as 0, then the under speed alarm is disabled.
7 Over battery
voltage warning
0-200%
(135%)
Rated battery voltage multiplying by this value is
regarded as over battery voltage warning value. When
the battery input is higher than the warning value and
comes into over battery voltage delay but still higher
(normal faults delay), then over battery voltage warns. if
the value is set as 200, then the over battery voltage is
disabled.
8 Under battery
voltage warning
0-200%
(67%)
Rated battery voltage multiplying by this value is
regarded as under battery voltage warn value. When the
battery input is lower than the warning value and comes
into under battery voltage delay but still lower (normal
faults delay), then under battery voltage warns. if the
value is set as 0, then the under battery voltage is
disabled.
9 Charger warning 1.0-30.0V
(30.0V)
When the gap between D+ and B+ is over than this
value, and there is charging failure but still high (normal
warning delay), then charge failure warns. Once the gap
is lower than the value, warns clear. If the value is set as
300, then the charge failure is disabled.

Notes
1 Over freq alarm 0-200%
(114%)
Rated frequency multiplying by this value is
regarded as under over frequency alarm value.
When the Freq is higher than the value and comes
into over freq delay but still higher (emergency
faults delay), then over frequency alarms, If the
value is set as 200, then the alarm is disabled.
2 Under freq alarm 0-200% (80%)
Rated frequency multiplying by this value is
regarded as under frequency alarm value. When
the Freq is lower than the value and comes into
under freq delay but still lower (normal faults
delay), then under frequency alarms, If the value is
set as 0, then the alarm is disabled.
3 Over voltage
alarm
0-200% (120%)
Rated voltage multiplying by this value is regarded
as over voltage alarm value. When the voltage is
higher than the value and comes into over voltage
delay but still higher (normal faults delay), then
over voltage alarms, If the value is set as 200, then
the alarm is disabled.
4 Under voltage
alarm
0-200% (80%)
Rated voltage multiplying by this value is regarded
as under voltage alarm value. When the voltage is
lower than the value and comes into under voltage
delay but still lower (normal faults delay), then
under voltage alarms, If the value is set as 0, then
the alarm is disabled.
5 Phase current
over-load alarm 0-200% (100%)
Rated current multiplying by this value is regarded
as over current alarm value. When the current is
