4.1Control Buttons

4.1.1On/Alarm Silence/Manual Self-Diagnostic Test

This button controls output power to connected load(s). It has three functions:

•On

•Alarm Silence

•Manual Self-Diagnostic Test

ON—Start the UPS by pressing this button for more than 3 seconds, then releasing the button (an alarm will sound briefly). If the ON button is pressed and utility is outside input parameters, the UPS will start on battery (dark start).

Alarm Silence—Silence a battery mode audible alarm by pressing this button for longer than one second, then releasing it.

Manual Self-DiagnosticTest—To initiate a Manual Self-Diagnostic, press this button for at least three (3) seconds while operating from utility power. UPS will switch to Battery Mode to detect bat- tery voltage and whether the UPS is operating normally.

If LED indicates the battery is weak: Allow the UPS to recharge the batteries for 8 hours. Retest the battery after recharge.

If LED still indicates the battery is weak after the battery has been retested, contact your local dealer, local Emerson representative or Channel Support Applications.

If LED indicates a Battery Fault: Contact your local dealer, local Emerson representative or Channel Support Applications.

If LED indicates a UPS Fault: Remove the load, retest the self diagnostic test, if LED indicated UPS Fault, Contact your local dealer, local Emerson representative or Channel Support Applica- tions.

4.2Status Indicators

4.2.1Status Change Button

The Status Change button determines the information displayed by the five LEDs on the front panel. The default information shown by the LEDs is the load level on the UPS. Pressing the Status Change button while the UPS is On prompts the LED display to show battery capacity for 5 seconds. This function assists in assessing the meaning of status indicators as described in 4.2.4 - UPS Status Indicators. See Figure 16 and Table 2 for the Status Change button’s location.

4.2.2Load Level Indicator

The five LEDs at the top of the front panel illuminate with a steady glow to indicate the load level on the output of the UPS. The LEDs show the load level as a range, ± 5%. The LEDs’ load level meanings and colors are:

LED 1	LED 2	LED 3	LED 4	LED 5
10-24% — Green	25-49% — Green	50-74% — Yellow	75-99% — Yellow	100% or greater — Red
