ON / OFF / Test Button
SELF TEST
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 two-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 ten-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 automati-
cally 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.
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 Inverter
output voltage and then the UPS must be turned OFF and restarted to reconfigure
the microprocessor and save the changes. The Inverter (on battery) output
voltage setting for the 120V models can be either 120VAC (default) or 127VAC.
Changing the Inverter output voltage to 127VAC, will also change the Buck
setpoint from 130VAC (default) to 136VAC. The Inverter (on battery) output
voltage setting for the 230V models can be either 230VAC (default) or 208VAC.
Changing the Inverter output voltage to 208VAC, will also change the Boost1
setpoint from 206VAC (default) to 198VAC.
