1.
Current reverse, no current, under current, over current, low current, high current, etc.
a.
Only when the average value of the channel current is greater than the
set alarm threshold of the current channel, the alarm function of the above
current-related items is activated; otherwise, the alarm status is forcibly
cleared to 0.
b.
As for whether the alarm needs to be separately met the respective alarm
conditions (above or below the respective alarm threshold).

c.
Check if the corresponding alarm register is open, closed by default
Alarm message
•
Undercurrent alarm. After the channel average current value is subtracted from the
overcurrent / undercurrent alarm threshold, the current value is still less than or
equal to the current channel start alarm start threshold. The overcurrent /
undercurrent alarm threshold will change as the average current changes.
Alarm
message
•
Over current alarm. After the channel average current value plus the over current /
under current alarm threshold, the current value is still greater than or equal to the
current channel start alarm start threshold. The over current / under current alarm
threshold will change as the average current changes.
Alarm message
•
Low current alarm, when the current is less than or equal to the channel current low
alarm threshold, an alarm occurs.
Alarm message
•
High current alarm. When the current is greater than or equal to the channel current
high alarm threshold, an alarm occurs.
Alarm message
•
No current alarm, when the absolute value of the current is less than 250mA, an alarm
occurs.
