Description
Alarm Input Bad

An input condition is out of tolerance. This item is used to indicate the input power fail, a test condition should not set this item on.

Alarm Output Bad

An output condition (other than OutputOverload) is out of tolerance.

Alarm Overload

The output load exceeds the UPS output capacity.

Alarm Bypass Bad

The Bypass is out of tolerance.

Alarm Output Off

The UPS has shutdown as requested, i.e., the output is off.

Alarm UPS Shutdown

The entire UPS has shutdown as commanded.

Alarm Charger Failure

An uncorrected problem has been detected within the UPS charger subsystem.

Alarm System Off

The UPS system is in the off state. For example: The UPS get the input power but does not startup the system.

Alarm Fan Failure

The failure of one or more fans in the UPS has been detected.

Alarm Fuse Failure

The failure of one or more fuses has been detected.

Alarm Awaiting Power

The UPS output is off and the UPS is awaiting the return of input power.

Alarm Shutdown Pending

A shutdown UPS command SDA countdown is underway.

Alarm Shutdown Imminent

The UPS will turn off power to the load in less than 5 seconds; this may be either a timed shutdown or a low battery shutdown.

Alarm Buzzer Status

To indicate the UPS buzzer is silent or alarm.

Economic Mode

The UPS is in the economic mode (act like a off-line UPS).

Emergency Power Off

The User pressed the Emergency Power Off button.
