Self-Test

UTILITY POWER

The UPS performs a self-test automatically when turned on, and every two weeks thereafter (by default). Refer to the User Configuration Items for details on changing the default interval.

Automatic self-test eases maintenance requirements by eliminating the need for periodic manual self-tests. During the self-test, the UPS briefly operates the connected equipment on-battery. If the UPS passes the self- test, it returns to on-line operation.

If the UPS fails the self-test, the UPS lights the replace battery LED

and immediately returns to on-line operation. The connected equipment is not affected by a failed test. Recharge the battery for 24 hours and perform another self-test. If it fails, the battery must be replaced.

Press and hold the button for a few seconds to initiate the self-test.

During normal operation, the UPS monitors the utility power and delivers power to the connected equipment. If your system is experiencing excessive periods of high or low voltage, have a certified electrician check your facility for electrical problems. If the problem continues, contact the utility company for further assistance.

On-LineThe on-line indicator illuminates when the UPS is supplying utility power to the connected equipment. If the indicator is not lit, the UPS is supplying battery power and the UPS sounds an alarm—four beeps every 30 sec- onds.

Utility Voltage

230V 120V

The UPS has a diagnostic feature that displays the utility voltage. Plug the UPS into the normal utility power.

Press and hold the button to view the utility voltage bar graph dis- play. After a few seconds the five-LED display on the right of the front panel shows the utility input voltage. Refer to the figure at left for the voltage reading (values are not listed on the UPS).

The UPS starts a self-test as part of this procedure. The self-test does not affect the voltage display.

The display indicates the voltage is between the displayed value on the list and the next higher value. For example, with three LEDs lit, the input voltage for 120V models is between 114 and 124 Vac, and for 230V mod- els is between 229 and 248 Vac.

If no LEDs are lit and the UPS is plugged into a working AC power outlet, the line voltage is extremely low.

If all five LEDs are lit, the line voltage is extremely high and should be checked by an electrician.
