(Symmetra Power Array, Continued)

 

 

Item

Description

 

 

Load Assuming No

Connected load as a percentage of the capacity of the

good battery modules, assuming all good modules

Redundancy

are available for power.

 

 

 

 

Connected load as a percentage of the capacity of the

Allowing For

good battery modules, assuming one [two, no] good

module is reserved for redundancy. The value of

n+[1] Redundancy

redundancy (n+0, n+1, n+2) is taken from the Alarm

 

 

if Under setting (see below).

 

 

(Battery Power)

Battery power available, in kilovolt-amps.

Capacity

 

 

 

(Load)Alarm

Load alarm threshold, in kilovolt-amps. If the load is

at or above this setting, an alarm sounds. Changeable

if Over

in the UPS Characteristics menu.

 

 

 

Installed

Number of power modules/batteries installed in the

Symmetra Power Array.

 

 

 

Bad

Number of power modules/batteries that have failed.

 

 

 

Redundancy of the Symmetra Power Array, given the

 

present load and battery capacity. A Fault Tolerance

Fault Tolerance

of n+2, for example, means that two modules could

 

fail and there would be enough power for the load in

 

the event of utility lin e power outage.

 

 

(Fault Tolerance)

Low redundancy alarm. If the Fault Tolerance goes

below this setting, an alarm sounds. Changeable in

Alarm if Under

the UPS Characteristics menu.

 

 

 

Voltage

Total voltage of the batteries, in volts DC.

 

 

(Battery Charge)

Battery charge as a percentage of capacity.

Capacity

 

 

 

Runtime

Estimated runtime on-battery with the present load,

based on the latest Run Time Calibr ation (Sec. 4.3).

 

 

 

(Runtime)

Runtime alarm threshold, in minutes. If the Runtime

reading falls below this setting, an alarm sounds.

Alarm if Under

Changeable in the UPS Characteristics menu.
