5.0 Operation

5.7 Extended capabilities - continued

Output voltage, internal temperature, battery voltage, battery capacity - The UPS continuously monitors the rms output voltage, internal temperature in degrees Celsius, battery voltage, and the remaining battery capacity as a percentage of the fully charged condition. This information is valuable for troubleshooting purposes.

5.7.3 Power management

Shut down - While operating on-battery, the UPS may be directed to shut down following a user set delay. Controlled shut down of the UPS conserves battery capacity and extends battery life because the UPS is not allowed to run until all battery capacity is exhausted.

Shut down with delayed restart - The UPS may be directed to shut down in any mode following a user set delay, then restart after another user set delay. The restart delay may be used to stagger power up multiple network servers protected by multiple UPSs.

Simulate power failure - The UPS may be directed to simulate a power failure by briefly operating on-battery. This function is useful for test purposes.

Turn off - The UPS may be directed to turn off immediately or following a user settable delay.

5.7.4 Operation customizing

Alteration of many UPS operations is possible to suit specific applications. In order to use the customizing features of the UPS, all Option switches must be set to the on (I ) position. Functionality of the option switches is not lost as all such functions are duplicated by the UPS monitoring software. Once any of the Option switches are returned to the off position, functionality governed by the position of all Option switches is also restored.

Battery test operation - The battery test can be customized to automatically run upon startup, upon startup and once every 7 days thereafter, upon startup and once every 14 days thereafter, or never. The UPS’s battery test operation default setting is upon start and every 14 days thereafter.

Transfer voltage - The UPS’s upper and lower transfer voltages can be customized over a wide range. Default settings are given in section 9.0.
