Description of the alarms
CODE
DESCRIPTION
REASON FOR THE ALARM
A01
Battery voltage too low
Battery voltage under minimum threshold for a time longer than set.
A02
Battery voltage too high
Battery voltage under maximum threshold for a time longer than set.
A03
BRK1 breaker timeout
Breaker BRK1 of line SRC1 did not perform the opening or closing operation before the timeout. The opening or
closing control is inhibited after the alarm has been generated. The alarms are only generated if one of the power
sources is present, i.e. higher than the minimum programmed thresholds.
A04
BRK2 breaker timeout
As above, referred to BRK2.
A05
BRK3 breaker timeout
As above, referred to BRK3.
A06
Incorrect phase sequence Line SRC1
The phase sequence detected on line SRC1 does not correspond to the programmed value.
A07
Incorrect phase sequence Line SRC2
As above, referred to SRC2.
A08
Incorrect phase sequence Line SRC3
As above, referred to SRC3.
A09
Load timeout not powered
The load was not powered for a time longer than that programmed under P08.03 either because there were no
available power lines or because the breakers were both open.
A10
Local battery charger failure
Alarm generated by the input programmed with the
Local battery charger alarm
function connected to an external
battery charger when at least one of the sources is in the limits.
A11
Genset battery charger 1 failure
Alarm generated by the input programmed with the
genset 1 battery charger alarm
function connected to an external
battery charger when at least one of the sources is in the limits.
A12
Genset battery charger 2 failure
As above, referred to genset 2.
A13
Genset battery charger 3 failure
As above, referred to genset 3.
A14
Emergency
Alarm generated by the opening of the external
Emergency
input. All breakers are opened.
A15
BRK1 breaker protection trip
Breaker BRK1 opened because its overcurrent protection tripped, as indicated by the specific input with the
Line 1
breaker protection trip
function.
A16
BRK2 breaker protection trip
As above, referred to BRK2.
A17
BRK3 breaker protection trip
As above, referred to BRK3.
A18
BRK1 breaker withdrawn
Breaker BRK1 is not available because the input with the
Line 1 breaker withdrawn
indicates that the breaker is not
present in its housing.
A19
BRK2 breaker withdrawn
As above, referred to BRK2.
A20
BRK3 breaker withdrawn
As above, referred to BRK3.
A21
SRC1 genset line not available
Alarm generated by the
SRC1 line genset ready input.
A22
SRC2 genset line not available
As above, referred to SRC2.
A23
SRC3 genset line not available
As above, referred to SRC3.
A24
Maintenance hours SRC1
Alarm generated when the maintenance hours related to the SRC1 line reach zero. See menu M12. Use the
Control
menu
to restore the operating hours and reset the alarm.
A25
Maintenance hours SRC2
As above, referred to SRC2.
A26
Maintenance hours SRC3
As above, referred to SRC3.
A27
Maintenance operations BRK1
Alarm generated when the number of operations related to breaker BRK1 of line SRC1 reach the value set in menu
M12. Use the Control menu to restore the operation and reset the alarm.
A28
Maintenance operations BRK2
As above, referred to BRK2.
A29
Maintenance operations BRK3
As above, referred to BRK3.
A30
Auxiliary voltage breaker alarm
The device which manages the draw of auxiliary voltage from the available line (e.g. Lovato ATLDPS1) indicates a
fault/malfunctioning.
A31
NPL (Non-Priority Load) breaker timeout
The non-priority load breaker did not perform the opening or closing operation before the timeout. The opening or
closing control is inhibited after the alarm has been generated. The alarms are only generated if one of the power
sources is present, i.e. higher than the minimum programmed thresholds.
A32
TB1 Tie breaker timeout
Tie breaker TB1 did not perform the opening or closing operation before the timeout. The opening or closing control
is inhibited after the alarm has been generated. The alarms are only generated if one of the power sources is
present, i.e. higher than the minimum programmed thresholds.
A33
TB2 Tie breaker timeout
As above, referred to tie breaker TB2.
A34
NPL (Non-Priority Load) breaker protection trip
NPL breaker opened because its overcurrent protection tripped, as indicated by the specific input with the
NPL
breaker protection trip
function.
A35
TB1 tie breaker protection trip
TB1 tie breaker opened because its overcurrent protection tripped, as indicated by the specific input with the
TB1 tie
breaker protection trip
function.
A36
TB2 tie breaker protection trip
As above, referred to TB2 tie breaker.
A37
NPL (Non-Priority Load) breaker withdrawn
NPL breaker is not available because the input with the
NPL breaker withdrawn
function indicates that the breaker is
not present in its housing.
A38
TB1 tie breaker withdrawn
TB1 tie breaker is not available because the input with the
TB1 tie breaker withdrawn
function indicates that the
breaker is not present in its housing.
A39
TB2 tie breaker withdrawn
As above, referred to tie TB2 breaker.
