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.
● On-battery output voltage (220/230/240 Vac versions only) - The UPS’s on-battery
