Events (alarms and messages)
Each of the following listed events, alarm or message, can be displayed on the LCD screen, on a PC with the
software “Data Protection” installed or with the monitoring system “iUPSGuard”.
Alarms and Messages are differently specified because the
alarms
are indicating an abnormal functioning of the
UPS (which are additionally signaled with the
LED ALARM
and acoustically with the
buzzer
), while the
messages
indicate the various states of operation of the UPS (stored in the events list, but not activating the LED ALARM
and the acoustical alarm).

REGULATION BOARD FAILURE
A blocked DSP on the Control board causes this alarm and
consequently the shut-down of Rectifier and Inverter and
the opening of K3.
4004
UPS FAILURE ON PARALLEL SYSTEM
The master unit detected the slave unit missing on the
communication bus even though “Q1 – External UPS Output
Circuit Breaker” is still closed.
4006
BUS JA CRC FAILURE
The parallel communication bus system is subject to high
errors rate on channel JA.
4007
BUS JB CRC FAILURE
The parallel communication bus system is subject to high
errors rate on channel JB.
4008
BUS JA FAILURE
There is an interruption in the channel JA of the parallel
communication bus system.
4009
BUS JB FAILURE
There is an interruption in the channel JB of the parallel
communication bus system.
4010
CONNECTIVITY BUS FAILURE
The connectivity communication bus is faulty or
interrupted.
4011
EARTH LEAKAGE CURRENT
The unit has detected an earth leakage current above a
configured threshold (typically 5% of the maximum rated
input current).

a blown fuse and consequently it is shut down.
Clearance of this condition allows you to restart the
Rectifier.
4102

K4 not closed despite a closing command being issued.
Signaled by auxiliary contact.
Rectifier cannot start.
4103
K4 OPENING FAILURE
