Mimic diagram

Figure 2.7 LCD Mimic diagram

Four digit alpha-numeric display

The four digit alpha-numeric display provides a metering facility which can be selected to show the input

voltage/frequency, output voltage/frequency/load together with battery voltage and the internal enclosure

temperature. Details of the meter facilities are provided on page 4-3.

A variety of operating status and fault codes are also shown on the display, as described throughout this

manual.

Load transfer

Load transferred to bypass due to loss of UPS Inverter output.

Bypass defective

Bypass input abnormal, UPS fails to transfer to bypass

Utility supply defective

Utility supply defective at the UPS input terminals.

UPS OFF

This mimic is displayed when the utility power is first applied to the UPS, or if the UPS is

turned OFF. It shows that the battery is being charged from the utility (LINE) but the LOAD

is isolated from the UPS, and is therefore unpowered.

UPS ON

This mimic is displayed during normal UPS operation. It shows the battery being charged

from the utility (LINE) and the LOAD connected to the UPS output – and therefore being

supplied with processed, backed-up power.

ON BATTERY MODE

This mimic is displayed if the utility supply fails. It shows the battery now providing the UPS

and LOAD power. The battery will sustain the UPS output until it is discharged, whereupon

the UPS will shutdown.

LOAD ON BYPASS MODE

This mimic is displayed if the UPS develops a fault (or is overloaded), whereupon the load

is transferred to the bypass line and therefore connected directly to the unprotected utility

supply (LINE). The battery will remain on charge if the UPS charger is healthy.

The load can be manually switched between the UPS and Bypass by simultaneously

pressing the ON and UP buttons for approximately 5 seconds.

LINE UPS LOAD

LCD Mimic diagram

The LCD Mimic indicates the existing power flow through the UPS. The LINE,

UPS, LOAD and BATTERY symbols are permanently shown on screen and their

interconnecting lines appear depending on the UPS mode of operation – see

below.

Note that the arrowheads shown in Figure 2.7 are used in conjunction with the

LCD meter display to identify the source of the meter indication.
