For all alarm conditions, the clear time is the same as the set time. In order for the alarm to
be cleared, the alarm condition must be absent continuously for the entire Delay.

1
The amount of time a phase voltage must remain below the
Under Voltage Threshold before the Under Voltage Alarm
status is set.
Range: 0.1 to 3276.7
Default: 10.0
The percentage of nominal power that determines when the
Reverse Power Alarm status is set (after the Reverse
Power Delay). Nominal Power = Nominal Voltage x Nominal
Current.
For Grid 1, the Reverse Power alarm will be triggered if a
circuit's active power exceeds the Reverse Power
Threshold for a time period longer than Reverse Power
Delay.
For Grid 2, the Reverse Power alarm will be triggered if a
circuit's active power falls below the Reverse Power
Threshold for a time period longer than Reverse Power
Delay.
Range: -100 to 99
Default: -10
1
The amount of time a grid must remain below the Reverse
Power Threshold before the Reverse Power Alarm status is
set.
Range: 0.1 to 3276.7
Default: 10.0
The current above which the Over Current Alarm status is
set (after the Over Current Delay), as a percentage of the
Nominal Current parameter.
Range: 110 to 250
Default: 110
1
The amount of time a phase current must remain above the
Over Current Threshold before the Over Current Alarm
status is set.
Range: 0.1 to 3276.7
Default: 10.0
The phase voltage above which the Over Voltage Alarm
status is set (after the Over Voltage Delay), as a percentage
of the Nominal Voltage parameter.
Range: 101 to 250
Default: 115

The amount of time a phase voltage must remain above the
Over Voltage Threshold before the Over Voltage Alarm
status is set.
