Table 7 Warning Alarm Types
Type Description
When the controller detects the corresponding data
value ≥ (overvoltage, overfrequency alarm, etc.) or ≤
(undervoltage, under frequency alarm, etc.) the
threshold value, the alarm is enabled and the action
type is selected, the controller will send out a
warning signal.
When the controller detects that the absolute value
of busbar power value (power is negative) ≥ the set
threshold value, the alarm is enabled and the action
type is selected to warn, the controller will send out a
warning signal.
When the controller detects that the power value of
the busbar (power is positive)≥ the set threshold
value, the alarm is enabled and the action type is
selected, the controller will send out a warning
signal.
When the controller detects the loss of busbar
phase, the controller will send out a warning signal
when the alarm is enabled.
When the controller detects the reverse phase
sequence of the busbar and the alarm is enabled,
the controller sends out a warning signal.
When the controller detects that the voltage
unbalance percentage of the busbar ≥ the set
threshold value, and the alarm is enabled and the
action type is selected, the controller will send out a
warning signal.
When the controller detects the corresponding data
value ≥ (overvoltage, overfrequency alarm, etc.) or ≤
(undervoltage, under frequency alarm, etc.) the
threshold value, the alarm is enabled and the action
type is selected, the controller will send out a
warning signal.
