5.7.8 DC Setting 1. There are three related pages, as shown below:
DC Volt Alarm
Over: 58.5V
Low: 45.0V
Under: 45.0V
Amb. Temp Alarm
High: 25°C
Low: 0°C
Load Shunt
None
Shunt Coeff:
None
Use “” or “” to select one page or one of the parameters, and “” or “” to
select the parameter value. Press “ENT” to confirm and save.
2. The value description of the parameters is listed below:
Table 5-16 Value description of DC settings
Parameter Range Default Value description
Over
(over-voltage) 58.5V
The “DC Over Voltage” alarm will be raised when
the system DC output voltage is higher than the
value of “Over”
Low
(low-voltage) 45.0V
The DC low voltage alarm will be raised when the
system DC output voltage is lower than the value
of “Low”
Under
(under-voltage)
40V ~ 60V
45.0V
The DC under voltage alarm will be raised when
the system DC output voltage is lower than the
value of “Under”
The values of
these three
parameters should
be: Over > Low >
Under
High (high
temperature)
10°C ~
100°C 40°C
The high temperature alarm will be raised when
the detected ambient temperature is higher than
the value of “High”
Low (low
temperature)
-40°C ~
10°C -5°C
The low temperature alarm will be raised when
the detected ambient temperature is lower than
the value of “Low”
The value of
parameter “High”
must be higher
than that of
parameter “Low”
Load shunt Y, None None Set according to the system actual situation
Shunt Coeff Dependent on system
type
In the system with a load shunt, this parameter can be set only when
the parameter “Shunt” (as a system type) is set to “Set”.
