7.5.2. Troubleshooting guide.
•
If the UPS is not working properly, check the information
shown on the LCD of the control panel and act accordingly
depending on the device model.
•
Consult this section’s troubleshooting guide and try to solve
the problem. If it persists, contact our Technical Service and
Support ( T.S.S. ).
•
If it is necessary to contact our Technical Service and
Support ( T.S.S. ), provide the following information:
ˆ
UPS model and serial number.
ˆ
Date on which the issue occurred.
ˆ
Full description of the issue, including information
provided by the LCD or LEDs and state of the alarm.
ˆ
Power supply conditions, type of load and level of load
applied to the UPS, ambient temperature, ventilation
conditions.
ˆ
Battery information (capacity and number of batteries),
whether the device is a (B0) or (B1).
ˆ
Any other information considered relevant.
CODE ALARM DESCRIPTION POSSIBLE CAUSE SOLUTION
A1 INPUT FAILURE The input line’s voltage or frequency is
out of tolerance.
Mains instability or failure.
Incorrect phase rotation.
Check connections to electrical mains.
Check stability of mains voltage.
A2 PHASE SEQ ERROR The phase rotation in the rectifier input
line is incorrect.
Incorrect connection of power cables. Check phase rotation.
A3 BOOSTER STOPPED The rectifier has been temporarily
disconnected and the batteries are
powering the inverter.
AC line voltage or frequency instability.
Possible failure in rectifier control circuit.
Check AC line voltage parameters.
Restart device.
A4 BOOSTER FAILURE The rectifier has been disconnected due
to an internal failure.
Possible failure in rectifier control circuit. Check which alarms are present and
perform indicated procedures.
Restart device.
A5 DC VOLTAGE FAILURE The DC voltage is out of tolerance. The batteries reach discharge voltage due
to power failure.
Measurement circuit failure.
Check actual value of DC voltage
measured.
In case of mains failure, wait for AC
voltage to be restored.
Check which alarms present and perform
relevant procedures.
Restart device.
A6 BATTERY TEST The rectifier’s voltage has been reduced
to start a brief controlled discharge of the
batteries.
Battery test started automatically or
manually by user.
Wait until end of test and check for
possible battery malfunction.
A7 BCB OPEN The battery circuit breaker is open. Battery circuit breaker open. Check state of battery circuit breaker.
Check functioning of circuit breaker’s
auxiliary contact.
Check connection between circuit
breaker’s auxiliary contact and UPS’s
auxiliary terminals.
A8 BATTERIES
DISCHARGING
The batteries are discharging. Batteries discharging due to a mains
failure.
Rectifier failure.
Check which alarms present and perform
relevant procedures.
A9 END BATT. BACKUP The batteries have reached the pre-alarm
discharge level.
Batteries discharging due to mains failure.
Rectifier failure.
Check which alarms present and follow
instructions.
A10 BATTERY FAILURE Failure after a battery test. Battery failure. Check batteries.
Restart the system.
A11 SHORT-CIRCUIT The current sensor has detected a short-
circuit at the output.
Problems in the loads.
Measurement circuit failure.
Check loads connected to UPS output.
A12 SHUTDOWN DUE TO
SHORT-CIRCUIT
The inverter is disabled due to a
prolonged short-circuit during a mains
failure or an overcurrent at the input of
the inverter bridge.
Short-circuit in loads during power failure.
Inverter bridge failure.
Temporary current spike.
Restart the system.
A13 INV. OUT OF TOL. The inverter’s voltage or frequency is out
of tolerance.
Inverter shutdown due to an alarm.
Inverter failure.
Check which alarms present and perform
relevant procedures.
A14 BYP PHASE SEQ ERR The phase rotation of the bypass line is
incorrect.
Incorrect connection of power cables. Check phase rotation.
A15 BYPASS FAILURE The voltage or frequency of the bypass
line is out of tolerance.
Bypass line instability.
Incorrect phase rotation.
Check mains connection.
Check mains voltage stability.
A16 BYPASS --> LOAD The load is powered through the bypass
line.
Temporary transition due to inverter
failure.
Check status of inverter and alarms
present.
A17 RETRANSFER DISABLED The load is disabled on the bypass line. Very frequent switching due to load
current spikes.
Problems with static switch.
Reset the system.
Check load current spikes.
