Code

Alarm

Description

4340

INVERTER CONTROL FAILURE

The “Slave” oscillator is not in synchronized with
the Master; thus causing the shut-down of its
Inverter.
If after a restart the condition remains, the LED
inside the Inverter symbol on the panel will not
light up, indicating that this Inverter cannot
supply the Load anymore.

4404

K6 CLOSING FAILURE

K6 open despite a closing command being
issued. Signaled by auxiliary contact.
The Load cannot be supplied by Automatic
Bypass.

4405

K6 OPENING FAILURE

K6 closed despite an opening command being
issued. Signaled 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.
Only a GE Service Engineer can reset the alarm.

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

The Fan Control Board indicates a malfunction of
one or more ventilators.

4530

LOAD LOCKED ON UTILITY

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

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 (Emergency
Power Off) from an external safety device
connected on Customer Interface Board.
Consequently K4, K6, K7 open, Rectifier, Inverter
and SSM are switched Off.

4570

OVERLOAD

The UPS system is in an overload condition

105% on Inverter, or

150% on Utility.

With Utility unavailable, a sequence of “stop
operation” starts.
Time out depends on degree of overload.
