Emerson Series 610 manual Module Monitor/Mimic Display Screen, Input Metering Displays

Operation

3.2.3Module 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.

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).

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.
