Alarm Levels
Using PowerLogic software with a PM850 or PM870, multiple alarms can be set up for one
particular quantity (parameter) to create alarm “levels”. You can take different actions
depending on the severity of the alarm.
particular quantity (parameter) to create alarm “levels”. You can take different actions
depending on the severity of the alarm.
For example, you could set up two alarms for kW Demand. A default alarm already exists
for kW Demand, but you could create another custom alarm for kW Demand, selecting
different pickup points for it. The custom kW Demand alarm, once created, will appear in
the standard alarm list. For illustration purposes, let’s set the default kW Demand alarm to
120 kW and the new custom alarm to 150 kW. One alarm named kW Demand ; the other
kW Demand 150kW as shown in Figure 6–3. If you choose to set up two alarms for the
same quantity, use slightly different names to distinguish which alarm is active. The display
can hold up to 15 characters for each name. You can create up to 10 alarm levels for each
quantity.
