Shutdown

This option guides you through a series of screens that enable you to complete your shutdown configuration.

The configuration screens are listed below in their display order. You can also access these screens individually at any time.

• Shutdown Settings

This screen summarizes your shutdown configuration and also enables you to configure some steps of the shutdown sequence.

The summary includes timing and delays, with the “base time” being the occurrence of the On Battery event.

The options chosen on this screen can affect the configuration of events, set up in Event Configuration. This can include which events are selected to cause a shutdown. Read the other sections below for further information.

• Power Outage Configuration

• Power Outage Configuration and Shutdown on Event Configuration

• Interactivity in shutdown durations

The Power Outage Configuration options define the response when a power problem causes the UPS to switch to battery operation.

• Immediately initiates a shutdown as soon as a On Battery event indicates that the UPS switched to battery power.

• After UPS has been on battery for initiates a shutdown when the UPS has been operating on battery power for the period of time configured here.

• At runtime limit configures the Low Battery event to shut down; this is viewable on the Event Configuration screen.
The Low Battery event is generated when the UPS is on battery and the battery runtime falls below the number of seconds you set here.
The Battery Discharged event is generated when the UPS is on line and the battery runtime falls below the number of seconds you set here.

• Do not shut down during a power outage relies on the Low Runtime Warning event to cause a shutdown.
The Low Runtime Warning event is generated when battery runtime falls below the combined time configured for Application and Operating System shutdown: see the Operating System and Application Shutdown section of this screen.

NOTE: This Low Runtime Warning event does not display on the Event Configuration screen as it is not configurable (because it always causes a shutdown).

When you select different radio button options here, the displayed summary information on this screen (under the Shutdown Summary heading) changes.

Choosing one of the four Power Outage Configuration options on Shutdown Settings (discussed above) works interactively with the Event Configuration Shutdown checkboxes for different events.

You can see this by selecting a radio button option here, pressing Apply, and going to the Event Configuration screen to note the differences.

This is also true in reverse: changing a Shutdown checkbox for an event in Event Configuration can change which radio button option is selected here on Shutdown Settings.

If the check box is selected, a warning appears on the screen to inform you of this.

With this On Battery option selected:	...the Shutdown checkbox of these events is selected
With this On Battery option selected:	Low Battery	On Battery	Time on Battery Threshold Exceeded
Immediately	No	Yes	No
After UPS has been on battery for	No	No	Yes
At runtime limit	Yes	No	No
Do not shut down in the event of a power outage	No	No	No

* The Low Runtime Remaining event is always configured to shutdown for these Power Outage Configuration options. This event is only displayed in the Event Log, and is not configurable on the Event Configuration page.

For example, if you choose Immediately here and apply it, you will see in the On Battery row of Event Configuration that the Shutdown checkbox has been selected automatically.

And if you then clear the Shutdown checkbox for the On Battery event of Event Configuration, apply it, and return here to Shutdown Settings, the Immediate option will NOT be the selected option.

Upon installation, the value for time for operating system to shut down is set to a value specific to your UPS model, usually 60 or 120 seconds.

Another field on this Shutdown Settings screen, Time required for command file to run under Operating System and Application Shutdown, interacts with the Command File Execution Duration field for the Shutdown Starting event on Event Configuration. When they are changed, these fields automatically update each other.

(Note that the Time required for command file to run field only displays on Shutdown Settings when you have chosen a command file).
