-Output Current (L-N current displayed in Amperes or as a % Load)

-Output Power (displayed in kW or kVA)

-Output Frequency (of inverter and bypass mains)

Input Parameters

- Input Voltage (L-N for Bypass input)

Battery Parameters

-Battery Voltage

-Battery Current

-Battery Charge (in %)

Temperature

- Temperature (°C) at critical points

Bargraph Selection

This following functional area shows the various UPS load and battery charging conditions.

16. Load Battery

The amber led situated at the beginning of the % Autonomy bargraph illuminates when the battery voltage has discharged to 1.8V /cell and indicates that the battery is approaching its low voltage cut-off point and the UPS will shortly shutdown.

17. % Battery state Autonomy time bargraph

When the battery is being charged (normal) the six leds illuminate progressively to indicate the state of battery charge as a percentage of a charge. When the battery is discharging (battery on-load) the bargraph function changes to provide an indication of the remaining battery autonomy time, each step indicate approximately 2 minutes. With a fully charged battery all five LEDs are illuminated indicating greater than 10 minutes remaining, as the autonomy falls below this time the LEDs will extinguish in steps starting from the right-hand end.

18. % Load bargraph

The six leds illuminate progressively to indicate the applied load as a percentage of the rated maximum current increasing in 20% steps to 100% of full load when all five are illuminated.

19. Overload

The amber LED situated at the end of the % Load bargraph illuminates if the applied load exceeds 100% of modules rated output current. This indication will be accompanied by an audible alarm a alarm message.
