Emerson 1000 User Manual

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-Diagnostic Test—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.

When the UPS is operating in either Normal Mode or Battery Mode, pressing the Off button for more 

than three seconds will shut down the UPS.

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.

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:

NOTE
Refer to Figure 16 and Table 2 for details about the LEDs’ meaning.

25-49% — Green
