Toshiba 1800 manual Battery Check Function, The Function Control Button

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

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.
