The lower limit
of frequency
Meter voltage frequency (nonzero)> the
lower limit of frequency setting
the action value 0
indicates to close the
alarm object
The upper
limit of power
The total value of primary active power >
the upper limit of power setting value
the action value 0
indicates to close the
alarm object
Voltage
open-phase
In three-phase four-wire, one phase or
two-phase in three voltage <110V
Three-phase three-wire ,one phase or
two-phase in three line voltage<190V
The alarm can be set
to turn on or off
Status 1 open
Status 1 from the closed to the open
The alarm can be set

5.6.1 Alarm action condition
SPM33 generated alarm condition: the setting object meet the action conditions,
and need to meet the time requirements in order to be really activated.
Throughout the delay period, if the object is within the return limits, then the
alarm setpoint is not activated. If the delay time is 0, it means that once the
monitoring object is more limited, the alarm setpoint generated immediately.
There is a fixed value or more objects is active, the alarm is generated. After the
alarm is generated, all the setting object if returned within the limit, the alarm will
disappear.
