SELF TEST
English
Press and release the ON/OFF/Test Button after one beep to turn the UPS ON
and supply power to the load. The load is immediately powered while the UPS
runs a five-second self test. Press and release the ON/OFF/Test Button after
one beep to turn the UPS OFF. The UPS will continue to charge the batteries
whenever it is plugged into an AC outlet and there is AC present.
The self test feature is useful to verify the correct operation of the UPS and the
condition of the batteries. With the UPS in the normal On-Line mode, press
and hold the ON/OFF/Test Button for approximately 4 seconds (four beeps),
then release the button. The UPS will perform a five second self test. During
the self test, the UPS will switch to battery power and the On-Line LED will
blink and the audible alarm will sound. The length of the test that is
automatically performed every two weeks is longer than the start-up or user
invoked test. This test will run for approximately fifteen seconds to measure
the battery’s capability to provide an acceptable amount of runtime. If the UPS
fails a self test, one of the LEDs will remain illuminated indicating the type of
problem. (see section 5 Troubleshooting)
Note: The UPS will automatically perform a self test on start-up and every two
weeks.
DIP SWITCH SETTINGS
The DIP Switch setting may be changed by the user to set the desired inverter
(on battery) output voltage. The DIP Switch must be set to the desired output
voltage and then the UPS must be turned OFF and restarted to reconfigure the
microprocessor and save the changes. The setting for the 120VAC units may
be 110VAC, 120VAC, or 127VAC. The 110/120VAC settings will adjust the
inverter (on battery) output voltage only. The 127VAC setting will adjust the
inverter (on battery) output voltage and the Buck set points.
