Self-correcting conditions: Sometimes, the alarm automatically clears when the condition resolves. For
example, if a load over current alarm is generated, the alarm is cleared when the current drops 0.25A below the
level (alarm hysteresis).
Types of Alarms
The ePDU is designed for durable, automatic operation. If a potential operating problem occurs, the ePDU
issues an alarm to alert you.
l
Alarms are displayed on the LCD and recorded in the event log. During an active alarm, the LCD flashes
amber until any button is pressed. If a power outlet LED on an Advanced Monitored (AM) or Managed (MA)
model is involved, it flashes.
l
Notices are indications of behavior reaching a set threshold, such as Output Over Voltage Warning. Notices
are displayed on the LCD and recorded in the event log. Notices do not require a response.
l
Events are conditions recorded in the event log as status information, such as Power On. Events do not
require a response.
Alarms, notices, and events are recorded in the event log as records of when alerts occurred and, if applicable,
when they were cleared.
Alarms, Notices, and Events
Table 18 describes the typical alarms, conditions, and event notifications (notices).
NOTE
The screensaver turns off when an alarm is generated.

Alarm Number: Name
Description
Type
008: Frequency Out of Range
Utility frequency greater or less than +/- 3 Hz of Nominal frequency.
Notice
018: Contact 2 Active
The signal for Dry Contact 2 is active.
Generates an alarm and is logged in the event log.
Alarm
019: Dry Contact 1 Active
The signal for Dry Contact 1 is active.
Generates an alarm and is logged in the event log.
Alarm
053: Fatal EEPROM Fault
This alarm occurs when the EEPROM experiences a Range Check
Failure alarm, an incorrect EEPROM model map alarm, or an EEPROM
Checksum Failure alarm.
Generates an alarm and is logged in the event log.
Alarm
063: Meter IC Fault
Communication is lost. This is probably due to Meter IC damage or
the DIN/DOUT photo damage.
Generates an alarm and is logged in the event log.
Alarm
102: L1 Over Current Critical
The Phase 1 input current amperage (A) reading is greater than the
value configured as the over current critical alarm threshold.
Generates an alarm and is logged in the event log.
