“ALARMS” TABLE
CODE 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 breaker is “ON”/“1”.
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 mode 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.
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 mode.
A27 REC NOT ACT Rectifier is not started due to a fault.

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 priority alarm.
A43 MAJOR ALR
Major priority alarm.
A44 BATT TS FAIL Batteries failed in the Battery Test.
A45 BATT CR OPEN Battery circuit breaker is open.
A47 INV RX T-OUT
