Operating Manual SG Series 10 –20 – 30 - 40 kVA

Code

Alarms

Meaning

4405

K6 OPENING

FAILURE

K6 closed despite an opening command being issued.
Signalled by auxiliary contact.

4406

SSM

FAILURE

A faulty current has been detected in the static-switch causing
the opening of the contactor K6 for 10 seconds.
After 3 times K6 remains definitively open.
The alarm reset can be done only from Service Center.

4408

K8 CLOSING

FAILURE

K8 not closed despite a closing command being issued.
Signalled by auxiliary contact.
The Load cannot be supplied by Automatic Bypass.

4409

K8 OPENING

FAILURE

K8 closed despite an opening command being issued.
Signalled by auxiliary contact.

4410

BYPASS UTILITY

OUT OF TOLERANCE

The Utility Bypass Voltage is out of the tolerances (± 10%).
K6 opens, synchronization with Utility is inhibited and transfer to
Utility is blocked.

4420

K3 CLOSING

FAILURE

K3 open despite a closing command.
Inverter is switched OFF.
It can be restarted manually after recovery of the alarm
condition.

4421

K3 OPENING

FAILURE

K3 not open despite an opening command.
Be aware the DC Capacitors could remain charged.

4520

NO INVERTER

POWER

The Load supplied by Utility exceeds the Inverter power.
The Load remains supplied by Utility until the alarm stays ON.

4522

FAN

FAILURE

A malfunction on the UPS ventilation system was detected.
No change for UPS operation.
Call immediately Service Center for intervention.

4530

LOAD LOCKED

ON UTILITY

Load is locked on Utility because 3 transfers on Utility have been
detected in a short time (default 30 seconds).
The transfer will be free after a time defined in parameter
(default 30 seconds).

4531

LOAD ON UTILITY BY

ERROR DETECTOR

Load is transferred to Utility because the error detector detected
a disturbance on the output voltage.

4563

EMERGENCY OFF

ACTIVATED

Alarm after detection of an EPO from an external safety device
connected on Customer Interface Board.
Consequently K3, K4, K6, K7, K8 open, Rectifier, Inverter and SSM
are switched Off.

4570

OVERLOAD

The UPS-System is in an overload condition >125% on Inverter,
or >150% on Utility.
With Utility unavailable, a sequence of “stop operation” starts.
Time out depends on Load quantity.

4571

OVERLOAD:

LOAD ON UTILITY

With Utility Bypass supply available and load >115%, the Load is
transferred on Utility.
Load will be transferred again automatically on Inverter when
Load <100%.

4581

INVERTER AND

UTILITY NOT SYNCH.

The voltages of Utility and Inverter are not synchronized, which
causes the opening of K6.

4697

BATTERY

OVERTEMPERATURE

Detection of Battery over temperature condition.
Can be deactivated by Service Center.

4698

BATTERY POWER

INSUFFICIENT

In case of Utility Failure, with the actual Load, the run time would
be below stop operation time (default 3 minutes).
