lights will light up, Generator stops running, displays " Under frequency " on the
current fault screen
Over voltage alarm
When the controller detects that the generator voltage is higher than “Over voltage
alarm”, Then start alarm delay and the duration (Normal alarm delay) have not
returned to normal, the alarm of over voltage is reported. "ALARM" lights will light up,
Generator stops running, displays " Over voltage " on the current fault screen.
Under voltage alarm
When the controller detects that the generator voltage is lower than “Under voltage
alarm”, Then start alarm delay and the duration (Normal alarm delay) have not
returned to normal, the alarm of under voltage is reported. "ALARM" lights will light
up, Generator stops running, displays " Under voltage " on the current fault screen.
Over current alarm
When the controller detects that the generator phase current is higher than “Phase
current over-load alarm”, Then start alarm delay and the duration (Normal alarm
delay) have not returned to normal, the alarm of over current is reported. "ALARM"
lights will light up, Generator stops running, displays " Over current " on the current

Non-balance current ratio alarm
When the controller is 2 phase 3 wire or 3 phase 4 wire, the controller detects that
the unbalance degree of the three-phase or two-phase current of the generator is
higher than the "Non-balance current ratio alarm".Then start alarm delay and the
duration (Normal alarm delay) have not returned to normal, the alarm of Non-balance
current ratio is reported. "ALARM" lights will light up, Generator stops running,
displays " Unbalance of AMP " on the current fault screen.
Maintenance Expiration Alarm
When the action after the primary maintenance expired set as “alarm”, When the
countdown to maintenance is detected as "0", Then start warning delay and the
duration (Normal alarm delay) have not returned to normal, the warning of
Maintenance expiration is reported. "ALARM" lights on, Generator stops running, and
displays "Maintain end" on the current fault screen.
