Overcurrent Alarm
If the Overcurrent Alarm is set for DISABLED, the Overcurrent Level and
Overcurrent Delay will have no effect.
Reverse Power Level
 When the Reverse Power Level is reached, an Instant trip is received.
 Configured as a percentage of Rated kW
 Range: –1.0 through –50%
Reverse Power Delay
 Reverse Power Delay determines the amount of Reverse Power
accumulation needed to cause an Alarm or Shutdown.
 Range: 0.1 – 20 seconds
Minimum Reverse Power
 The power level must exceed the Minimum Reverse Power continuously for
the calculated delay time before the configured Alarm or Shutdown action is
taken. Reverse power levels above (a less negative or positive power) this
setting will have no effect. When the power level falls below the Minimum
Reverse Power level an accumulation of reverse power is started. As the
power level increases above this level, the accumulated amount will be
reset to zero.
