3.2.2 Monitor/Mimic Display Screen
From Master Menu move the highlighted cursor to MONITOR/MIMIC DISPLAY. Press the Select
pad and the Monitor/Mimic screen is displayed.
Figure 7 Monitor/Mimic display screen
The Monitor/Mimic display screen is a simplified block diagram of the UPS system. This screen gives
the operator an overall view of the power flow through the UPS system. 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-sec-
ond intervals.
Input Metering Displays
Item 1 - Bypass Input: This block displays the bypass input voltage and the bypass input frequency.
The bypass circuit breaker is shown to the right of this block. The status of the circuit breaker is illus-
trated as open or closed.
Item 2 - UPS Input Pwr: This block displays the UPS input voltage and current. The input circuit
breaker is shown to the right of this block. The status of the circuit breaker is illustrated as open or
closed.
Item 3 - Battery Block: This 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 4 - UPS Ratings: This block displays the UPS module part number and kVA rating. The UPS
output voltage and frequency are also displayed in this block. The output circuit breaker is shown to
the right of this block. The status of the circuit breaker is illustrated as open or closed.
Item 5 - Load: This block displays the total output power to the critical load in kVA and kW. The
critical load current per phase is also displayed in this block. Note that kW is not displayed when the
load is on the bypass line. During an overload condition, the time remaining before transfer is dis-
played at the bottom of the load box.
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).
