Battery Check Function; The Function Control Button - Toshiba 1800 Series User Manual

Battery cHeck Function

During startup the UPS will perform an automatic 'Battery Check' to detect
whether a problem exists in the battery circuit. If the batteries pass the test,
the unit will start normal operation. If a problem is detected during the test the
"Warning/Fault" LED will activate. Other LED's may also activate. If this occurs
please refer to the "Troubleshooting" section on page 28 for a description of
the problem and possible solutions. it is important to note that when the
uPs has detected bad batteries, the battery backup mode is disabled.
The unit will continue to operate and provide clean power; however, since
there is no battery power available, the unit cannot provide backup power if
input power is lost.

The function control button is located on the display panel (see "Display Panel
Layout", page 19). This button is used to perform different UPS operations,
including initiating a self test, and silencing the alarm. A brief description of
each function follows:
1) self-test. In order to perform a self-test the UPS must be operating in the
normal mode (see "UPS Display Status and Operating Condition", page 22).
To initiate the self-test simply press and hold the Function Control button until
the audible alarm sounds. The self-test also performs the same battery check
described above.
2) alarm silence. The alarm silence feature is used to stop the audible alarm
from sounding. Any time the audible alarm is sounding, quickly pressing and
releasing (in less than 1 sec.) the Function Control button will silence the
alarm.
