Frommodule Master Menu move the highlighted cursor to MONITOR/MIMIC DISPLAY.Press the Select
padand the Monitor/Mimic screen is displayed.
TheMonitor/Mimic display screen is a simplified block diagramof the UPS module and power connections.
Thisscreen gives the operator an overall view of the powerflow through the UPS module. The screen consists of
threemajor sections: the input/UPS metering section, the load meteringsection, and the status and alarm mes-
sageareas. The metered parameter values on the Monitor/Mimicscreen are updated at one second intervals.

Input Metering Displays
Item1 -UPS Input Pwr. This block displaysthe UPS module input voltage and current. The Module Input
breakeris shown to the right of this block. The status of the circuit breaker is illustrated as open or closed.
Item 2 - Battery. The battery blockdisplays the DC bus voltage and the charge or dischargecurrent to or from
thebattery. This block reads MODULE DC BUS when the battery circuit breaker is open and BATTERY when
thebattery circuit breaker is closed during normal operation. This blockreads BATTERY EQUALIZEwhen
thebattery equalize charge voltage is used to rechargethe battery. The Module Battery Disconnect(MBD) is
shownto the right of this block. The status of the circuit breaker is illustrated as open or closed.
Output Metering Displays
Item3 -UPS Ratings. The module part number and kVArating are specified at the top of this block. The UPS
outputvoltage and frequency are alsodisplayed in this block. The Module Outputbreaker is shown to the right of
thisblock. The status of the circuit breaker is illustrated as open or closed.
Item 4 - Load. This block displays the module output power to the critical loadin kVA and kW.The critical load
currentper phase is also displayed inthis block.
NOTE
Allvoltage readings are phase-to-phase measurements(A-B, B-C, and C-A). All
currentreadings are phase measurements(A, B, and C).
