Operation

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 connections.
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 mes-
sage 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 Module 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. 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).
