System Events

When the PDU is operating, it continually monitors itself and the incoming utility
power. System events on the PDU can be indicated by horns, lights, messages, or all
three.
Select EVENTS from the menu bar on the main menu screen to look at the active
events screen. This screen shows any currently active alarms, notices, or commands.
For more information on using the events screen, see paragraph 6.2.7, on page 6−12.
S
System Event Horns – The system event horn beeps to alert an operator that an
event needing attention is taking place. The horn cycles at a half−second rate.
S
System Event Indicators – The status indicators on the PDU control panel work with
the event horn to let the operator know when the PDU is operating in any mode
other than normal. Only the ON indicator is visible during normal PDU operation.
The other indicators illuminate to indicate alarms or events. When an alarm occurs,
first check these indicators to see what type of event has taken place. For
descriptions of the status indicators, see paragraph 6.2.1.
S
System Event Messages – When a system event occurs, a message appears on the
LCD in the PDU status area. This message is also written to the Active Events Log
and may be added to the History Log. The messages are divided into four
categories: alarms, notices, status, and commands.
