Operating-modes
Normal Operation
– Under normal operation, the unit will show
"System OK" and a "Mains supply on" green light diode will be alight. Once
every 90 minutes, the system will check that the battery is connected. If the
battery is disconnected or there is inadequate connection in the battery circuit,
´Battery off´ will be displayed. The alarm will sound simultaneously. The alarm
will be automatically acknowledged once the battery is connected
Mains Failure
– If the mains voltage falls below 65 % of rated
voltage, or the frequency changes by >2 % from 50 Hz, red LED diodes
"Charger off" and "Battery supply on" will light up, and the green LED diode
"Mains" will be turned off. The alarm will sound.
The inverter will start in accordance with the preset values of "Soft start" and
“Delay". The inverter gives a nominal voltage ±2 %, measured with an RMS
instrument, as well as 50 Hz ± 0,1 %.
When the inverter is running, the display will show “Low battery” when then
battery is at 22 V.
When the battery voltage reaches 19 V, the inverter is shut down to enter into
sleep mode. This enables minimal power to be drained from the battery. The
display is shut down and the unit will wait until mains power is restored, at
which point it will restart automatically.
