Alarm codes and names can be seen by entering the ALR submenu.
Bypass mains voltage is different than the inverter reference signal
(e.g. its frequency is beyond synchronization limits or it has a total
harmonic distortion > %10)
Bypass mains voltage is higher than its upper limit
Bypass mains voltage is lower higher than its lower limit
Frequency of bypass mains voltage is beyond the frequency range
for bypass operation or bypass mains voltage is very low
Phase sequence of bypass mains voltages is not OK
Manual bypass switch is “ON”
Inverter block temperature is very high
RMS current drawn from any of the output lines exceeds its nominal
value
Inverter is not started due to a fault
Inverter operation is automatically stopped due to a fault
Output voltage is beyond its limits
This alarm is observed when information flow from master ups is
interrupted
Parallel Communication cable is unplugged or damaged
Input line/neutral voltage is higher than its upper limit
Input line/neutral voltage is lower than its lower limit
Frequency of mains voltage is beyond the frequency range for
normal operation or mains voltage is very low
Phase sequence of input mains voltages is not OK
Rectifier block temperature is very high
RMS current drawn from any of the input lines exceeds its nominal
value
DC bus voltages is higher than its upper limit
DC bus voltages is lower than its lower limit
may mean that the battery is empty during battery operation
Rectifier is not started due to a fault
Rectifier operation is automatically stopped due to a fault
Battery test is performed
It appears in case Load % x (N+1) / N > 100, for more information
refer to page:28
Depending on N description ( n+1, n+2…), this alarm is observed
when the qty of ups in the systems decreases below N value
Batteries are discharging after a mains failure
