1. 55 Square D Alarms About Alarms Phase A Pickup Under Voltage Phase A Dropout The CSN lets you relate pickups and dropouts in the alarm log You can sort pickups and dropouts by CSN to correlate the pickups and dropouts of a particular alarm The pickup and dropout entries of an alarm will have the same CSN You can also calculate the duration of an event by looking at pickups and dropouts with the same CSN Priorities Each alarm also has a priority level Use the priorities to distinguish between events that require immediate action and those that do not require action High priority if a high priority alarm occurs the display informs you in two ways the LED backlight on the display flashes until you acknowledge the alarm and the alarm icon blinks while the alarm is active e Medium priority if a medium priority alarm occurs the alarm icon blinks only while the alarm is active Once the alarm becomes inactive the alarm icon stops blinking and remains on the display e Low priority if a low priority alarm occurs the alarm icon blinks only while the alarm is active Once the alarm becomes inactive the alarm icon disappears from the display e No priority if an alarm is setup with no priority no visible representation will appear on the display Alarms with no priority are not entered in the Alarm Log See Chapter 7 Logging for alarm logging information If multiple alarms with differen
