History

 

Press the HISTORY pushbutton on the Active Events menu bar to display the His-

 

 

tory Log. The History Log lists up to the 500 system events in chronological order,

 

 

with the most recent event listed last (once 500 is reached, the earliest event

 

 

is overwritten). The end of the log (the most recent events) appears when you

 

 

display the screen; scroll upward to view older event listings. To scroll through

 

 

the events, press the up or down arrow pushbuttons on the menu bar. To return

 

 

to the Active Events screen, press the EVENTS pushbutton on the menu bar.

Meters

 

The Meter screens show the UPS meter readings for the unit. The default volt-

 

 

age displayed on these screens is phase-to-neutral. However, an authorized

 

 

Eaton Customer Service Engineer can change the screens to display the voltage

 

 

phase-to-phase (A-B, B-C, C-A). Press the METERS pushbutton on the main

 

 

menu bar to display the Unit Meter screens. To scroll through the meter screens,

 

 

press the up or down arrow pushbuttons on the menu bar. The current UPS

 

 

readings are displayed in the information area of the screen.

 

Output

The Output screen shows output voltage (phase-to-neutral), output current

 

 

(each phase), and frequency being supplied by the UPS, as well as the kVA, kW,

 

 

and power factor measurements.

 

Input

The Input screen shows input voltage (phase-to-neutral), input current (each

 

 

phase), and frequency of the incoming utility source, as well as the kVA, kW, and

 

 

power factor measurements.

 

Bypass

The Bypass screen shows the bypass input voltage (phase-to-neutral), input cur-

 

 

rent (each phase), and frequency of the incoming utility source, as well as the

 

 

kVA, kW, and power factor measurements.

 

Battery

The Battery screen displays the battery voltage (Vdc), the battery current

 

 

(Idc), the minutes of battery time remaining, and battery temperature. Battery

 

 

temperature must be set up by an authorized Eaton Customer Service Engineer.

 

 

When battery life decreases to less than 20%,Check Battery is displayed.

 

Output Current

The Output Current Screen displays a real-time bar graph of the output current

 

 

of the UPS. The graph shows the current for each phase.

Battery Discharge

 

The Battery Discharge Log Summary collects information when the unit is on

Log Summary

 

battery. The screen displays the total number of times since the last log reset

 

 

that the unit has transferred to battery. It also displays the date of the last log

 

 

reset, the average time spent on battery per event, and the total time on battery

 

 

since the last reset. Press the METERS pushbutton on the main menu bar to

 

 

display the Unit Meter screens. Scroll through the meter screens using the up or

 

 

down arrow pushbuttons on the menu bar until the Battery Discharge Log Sum-

 

 

mary screen is displayed.

Battery Discharge

 

The Battery Discharge Log screen displays the individual log entries including

Log

 

the date and time of the event, how long it was on battery, the unit load when

 

 

the event occurred, and the end voltage of the battery for that discharge period.

 

 

If no events have occurred, the screen will display LOG EMPTY. Press the LOG

 

 

pushbutton on the Battery Discharge Log Summary menu bar to display the Bat-

 

 

tery Discharge Log screen. To scroll through the individual events, press the up

 

 

or down arrow pushbuttons on the menu bar. To return to the Battery Discharge

 

 

Log Summary screen, press the SUMMARY pushbutton on the menu bar. To

 

 

clear the Battery Discharge Log, press the RESET pushbutton on the menu bar.

kW Demand Log

 

The kW demand log collects information on events where the unit load exceeds

Summary

 

a user-defined kW limit within a user-defined time interval. The user can choose

 

 

a time period up to 9999 minutes and a load limit up to 9999 kW. If the limit is

 

 

exceeded within a given time period a log event is created. The kW Demand Log

 

 

Summary screen displays the number of total times the limit has been exceeded

 

 

since the last log reset, the date of the last log reset, the maximum kW reading,

 

 

and the total time over the limit. It also displays the average kW over the limit

 

 

and an estimated number of kWh used over the limit. Both of these values are

 

 

calculated using the difference between the actual measurement reading and

 

 

the user-defined limit level. For example, during a 60-minute interval if the limit

 

 

is set at 10 kW and the measurement is a constant 15 kW for the entire period,

 

 

the average kW over would be 5 kW and the total kWh used over the limit would

 

 

be 5 kWh. Press the METERS pushbutton on the main menu bar to display the

 

 

Unit Meter screens. Scroll through the meter screens using the up or down ar-

 

 

row pushbuttons on the menu bar until the kWDemand Log Summary screen is

 

 

displayed.
