The predefined alarms have the following features:
Code
Description
Cause of alarm
A01 Voltage of the DC supply too low The voltage of the DC supply is below the lower threshold limit for longer than
the set time.
A02 Voltage of the DC supply too
high
The voltage of the DC supply is above the upper threshold limit for longer than
the set time.
A03 Source 1 circuit breaker timeout The Source 1 breaker has not performed any opening or closing operation with-
in the set maximum period. Once the alarm has been triggered, the ON or OFF
command is inhibited. The alarms are only triggered if at least one of the two
energy sources is available, that is to say it is above the programmed lower
limits.
A04 Source 2 circuit breaker timeout The Source 2 breaker has not performed any opening or closing operation with-
in the set maximum period. Once the alarm has been triggered, the ON or OFF
command is inhibited. The alarms are only triggered if at least one of the two
energy sources is available, that is to say it is above the programmed lower
limits.
A05 Source 1 wrong phase sequence
(SRC1)
The phase sequence measured on Source 1 does not match the programmed
phase sequence.
A06 Source 2 wrong phase sequence
(SRC2)
The phase sequence measured on Source 2 does not match the programmed
phase sequence.
A07 Load not powered timeout The load has not been powered for longer than the time programmed with
P08.03. This is either because the power supplies were not available, or be-
cause both breakers have remained open.
A08
Emergency
The external emergency OFF is triggered. The switching devices are opened.
A09 Source 1 breaker protection trip The Source 1 breaker has opened because an overcurrent protection device
has tripped. This is signaled by activation of the input with function Source 1
breaker protection trip.
A10 Source 2 breaker protection trip The Source 2 breaker has opened because an overcurrent protection device
has tripped. This is signaled by activation of the input with function Source 2
breaker protection trip.
A11 Breaker 1 (BRK1) withdrawn Source 1 breaker has been withdrawn. The corresponding input with the func-
tion Source 1 breaker withdrawn is activated.
A12 Breaker 2 (BRK2) withdrawn Source 2 breaker has been withdrawn. The corresponding input with the func-
tion Source 2 breaker withdrawn is activated.
A13

Alarm generated by the input Generator Source 1 ready.
A14
Generator Source 2 not available
Alarm generated by the input Generator Source 2 ready.

zero. See Menu P14 - Miscellaneous (Page 180
), in order to reset operating
hours and alarm.
A16 Maintenance Hours 2 This alarm is triggered if the maintenance hours for Source 2 reach the value
zero. See Menu P14 - Miscellaneous (Page 180
), in order to reset operating
hours and alarm.
A17 Maintenance operations 1 This alarm is triggered if the number of operating cycles for Source 1 reaches
the value set in Menu P14 (Page 180
). Use Commands menu to restore opera-
tion and reset the alarm.
A18 Maintenance operations 2 This alarm is triggered if the number of operating cycles for Source 2 reaches
the value set in Menu P14 (Page 180
). Use Commands menu to restore opera-
tion and reset the alarm.
