3.2.3 Module Monitor/Mimic Display Screen
From module Master Menu move the highlighted cursor to MONITOR/MIMIC DISPLAY. Press the
Select pad and the Monitor/Mimic screen is displayed.
The Monitor/Mimic display screen is a simplified block diagram of the UPS module and power connec-
tions. This screen gives the operator an overall view of the power flow through the UPS module. The
screen consists of three major sections: the input/UPS metering section, the load metering section and
the status and alarm message areas. The metered parameter values on the Monitor/Mimic screen are
updated at one second intervals.

Input Metering Displays
Item 1 - UPS Input Pwr: This block displays the UPS module input voltage and current. The Mod-
ule Input breaker is shown to the right of this block. The status of the circuit breaker is illustrated as
open or closed.
Item 2 - Battery: The battery block displays the DC bus voltage and the charge or discharge current
to or from the battery. This block reads MODULE DC BUS when the battery circuit breaker is open
and BATTERY when the battery circuit breaker is closed during normal operation. This block reads
BATTERY EQUALIZE when the battery equalize charge voltage is used to recharge the battery.
This block also shows BATTERY TEMPERATURE when the battery temperature sensor option is
installed. The Module Battery Disconnect (MBD) is shown to the right of this block. The status of the
circuit breaker is illustrated as open or closed.
Output Metering Displays
Item 3 - UPS Ratings: The module part number and kVA rating are specified at the top of this block.
The UPS output voltage and frequency are also displayed in this block. The Module Output breaker is
shown to the right of this block. 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 load in kVA and kW. The
critical load current per phase is also displayed in this block.
NOTE
All voltage readings are phase-to-phase measurements (A-B, B-C and C-A). All current
readings are phase measurements (A, B and C).
