NAME DEFINITION
A01 BYP BADSHAPE
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)
A02 BYP VOL HIGH Bypass mains voltage is higher than its upper limit
A03 BYP VOL LOW Bypass mains voltage is lower higher than its lower limit
A06 BYP SYN FAIL
Frequency of bypass mains voltage is beyond the frequency range for bypass
operation or bypass mains voltage is very low
A07 BYP SEQ FAIL Phase sequence of bypass mains voltages is not OK
A08 MNBYP SW ON Manual bypass switch is “ON”
A09 INV TMP HIGH Inverter block temperature is very high
A10 OUT OVERLOAD RMS current drawn from any of the output lines exceeds its nominal value
A11 BYP ACT Bypass is activated.
A12 INV NOT ACT Inverter is not started due to a fault
A13 INV BLCK Inverter operation is automatically stopped due to a fault
A14 VSEC NOT OK Output voltage is beyond its limits
A15 MASTER T-OUT This alarm is observed when information flow from master ups is interrupted
A16 CABLE UNPLUG Parallel Communication cable is unplugged or damaged
A17 INP VOL HIGH Input line/neutral voltage is higher than its upper limit
A18 INP VOL LOW Input line/neutral voltage is lower than its lower limit
A21 INP SYN FAIL
Frequency of mains voltage is beyond the frequency range for normal
operation or mains voltage is very low
A22 INP SEQ FAIL Phase sequence of input mains voltages is not OK
A23 REC TMP HIGH Rectifier block temperature is very high
A24 REC OVERLOAD RMS current drawn from any of the input lines exceeds its nominal value
A25 VDC HIGH DC bus voltages is higher than its upper limit
A26 VDC LOW
DC bus voltages is lower than its lower limit
may mean that the battery is empty during battery operation
A27 REC NOT ACT Rectifier is not started due to a fault
A28 REC BLCK Rectifier operation is automatically stopped due to a fault
A30 TESTING BATT Battery test is performed
A31 REDUND. LOST
It appears in case Load % x (N+1) / N > 100, for more information refer to
page:28
A32 N FAULT
Depending on N description ( n+1, n+2…), this alarm is observed when the
qty of ups in the systems decreases below N value
A33 REC OFF Rectifier is inactive
A34 INV OFF Inverter is inactive
A35 BYP OFF Bypass is inactive
A36 BYP PRI HIGH Priority is Bypass
A37 BATT DISCHAR Batteries are discharging after a mains failure
A38 VDC NOT OK DC bus voltage is out of its normal range
A39 T-AMP HIGH Ambient temperature exceeds its upper limit
A40 GENSET ON Generator friendly operation is activated
A41 EMG STOP ON Emergency stop is activated
A42 MINOR ALR Minor Alarm
A43 MAJOR ALR Major Alarm
A44 BATT TS FAIL Batteries failed in the battery test
