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 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
