The control and display panel LED indications are illustrated in figure
1-5 and described in the following text:
1. Bypass AC Input supply present:
This LED illuminates when the bypass AC input power switch is
closed and the Input supply is within off set value nominal voltage
(default ± 10%).
2. Load on Inverter:
This LED illuminates when the output power switch is closed and the
load is connected to Inverter via the input mains supply.
3. Load on bypass:
This LED illuminates when the output power switch is closed and the
load is connected to the bypass AC supply via the bypass static switch.
4. Battery Issues:
This LED illuminates when the battery is discharging and flashes when
the battery circuit breaker is open.
5. 5 LED bargraph indicating 0% load:
These LEDs illuminate progressively from the left to indicate the
applied load as a percentage of the maximum current load, increasing
in 20% steps to 100% full load when all five LEDS are illuminated.
The applied load reading is taken from the phase supplying the
highest load.
6. 5 LED bargraph indicating % battery charge state or battery time
remaining:
These LEDs illuminate progressively from the left to indicate the state
of charge of the battery as a percentage of full charge, increasing in
20% steps to 100% when all five LEDs are illuminated.
When the mains AC input supply fails and the UPS is operating on
the battery, this bargraph changes to give the battery time remaining.
With a fully charged battery all five LEDs will illuminate showing ten
minutes or more autonomy, as time elapses the LEDs will extinguish
in steps starting from the right hand side.
7. Overload indication:
This amber LED is situated at the end of the % load bargraph and
illuminates to indicate that the applied load has exceeded 100%. This
indication will be accompanied by audible and visual LCD warnings.
8. Low Battery:
This amber LED is situated at the end of the % battery charge
bargraph and illuminates when operating on battery to indicate that
the battery voltage is low at 1.8 volts per cell and that the UPS will
shortly shut down.
9. Alarm warning indication / alarm silence switch:
This red LED will flash whenever the UPS detects certain fault
conditions and will normally be accompanied by an audible warning.
Pressing the button will silence the audible warning but will not cancel
the visual indication if the fault condition is still present.
