Overload and Unbalance Alarms Function
The programmable alarms function includes alarm points for monitoring phase demand thresholds for
overload alarms, and neutral and negative-sequence demand thresholds for unbalanced loading alarms.
Each time that the current demand register is updated, the value is compared to the appropriate demand
alarm threshold. If the threshold is exceeded, the alarm point is set. See Alarms Function in this section
for more information on how to use the programmable alarms reporting function.
The Phase, Neutral, and Neg.-Sequence current demand alarm thresholds can be set from the ASCII
command interface using the SA-DI command or BESTCOMS (Figure 6-4). Alternately, HMI Screen
\SETUP\DMD\ALARMS can be used to set all demand alarms.
Figure 6-4. Reporting and Alarms Screen, Demands Tab
Table 6-5 provides the specifications for the Demand Alarm Threshold settings. The ASCII commands for
setting the Demand Alarm Thresholds are listed in Section 11, ASCII Command Interface.
