Table .4 Alarm list displayed in the LCD panel.
Screen 4.1: This alarm indicates that the rectifier is overloaded. The rectifier overload appears when the input
current of any phase is greater than the following ratio:
Where:
- Iin-ovl is Overload Input Current (A)
- Pout is Rated Output Apparent Power (VA)
- Vout_p-n is Rated Output Voltage phase-to-neutral (V)
Screen 4.2: This alarm indicates that the inverter is overloaded. The inverter overload appears when the
output current of any phase is greater than the rated output current.
Where:
- Iout is rated Output Current (A)
- Pout is Rated Output Apparent Power (VA)
- Vout_p-n is Rated Output Voltage phase-to-neutral (V) or when the total output active
power is greater than the following formula:
