ALARM
DESCRIPTION
POSSIBLE CAUSE
SOLUTION
A41
RECT. LOOP ERR.
The control cannot accurately regulate
the output voltage of the rectifier.
Regulation system fault.
Reset the system.
A44
INVERTER DESAT
The inverter is disabled due to the
intervention of the desaturation sensor of
the IGBT drivers.
Inverter bridge fault.
Reset the system.
A45
HIGH TEMP. SSW
High static switch heat sink temperature. Heat sink cooling fan fault.
Room or cooling air temperature too high.
Check fan operation.
Clean ventilation grilles and any air filters.
Check air conditioning system (if any).
A46
REDUND. LOST
Alarm only activated in parallel systems.
Continuity is not guaranteed in the event
of malfunction of one of the UPSs.
Total load greater than expected
maximum value.
Possible fault in measuring circuit.
Check load powered by system.
A47
PARAMETER SEND
ERROR
Internal error.
Microcontroller communication problems.
Contact our Technical Service and Support
(T.S.S.).
A48
PARAMETER RECEP.
ERROR
Internal error.
Microcontroller communication problems.
Contact our Technical Service and Support
(T.S.S.).
A49
TEST MODE ERROR
Internal error.
Microcontroller communication problems.
Contact our Technical Service and Support
(T.S.S.).
A60
RECTIFIER
DESATURATION
The rectifier is disabled due to the
intervention of the desaturation sensor of
the IGBT drivers.
Rectifier bridge fault.
Reset the system.
A51
BATTERY
TEMPERATURE
The temperature of the batteries is out
of tolerance limits. This alarm is only
activated if the battery probe is installed
and enabled.
Abnormal temperature inside external
battery cabinet.
Possible fault in measuring circuit.
Check temperature of batteries and
eliminate cause of alarm.
A53
FIRMWARE ERROR
The controller has detected an
incompatibility in the control firmware.
Software update not executed correctly.
Contact our Technical Service and Support
(T.S.S.).
A54
CAN ERROR
Internal error.
Microcontroller communication problems.
Contact our Technical Service and Support
(T.S.S.).
A55
PARALL. CAB.
DISCONN.
The parallel cable is not communicating.
Parallel cable disconnected or damaged.
Check the connection of the cable.
A56
MAINS UNBAL.
The input voltage of the rectifier is
unbalanced.
Problems in the AC power mains.
Device measurements circuit failure.
Check input voltage.
A59
BACKFEED RL ON
The backfeed relay has been activated.
This alarm only appears in the history.
Problems in static switch of bypass.
Check static thyristors.
A61
MAX VDC
Redundant power supply failure.
Internal failure.
Contact our Technical Service and Support
(T.S.S.).
A62
MAINS OV
Sudden increase in AC input voltage
(rapid sensor).
Voltage spike in the AC mains.
Possible internal failures.
Check mains voltage.
A63
STARTUP SEQ. FAILURE During UPS startup, a failure prevented
correct sequence execution.
Control devices in incorrect position or
incorrectly operated.
Possible internal failure.
Confirm that the position of the control
devices (circuit breakers, selectors) is the
one specified in the procedures.
A64
MAINS UV
Sudden drop in AC input voltage (rapid
sensor).
Voltage drop in AC mains.
Possible internal failures.
Check mains voltage.
