Code Alarm Description
4404 K6 CLOSING FAILURE
K6 open despite a closing command being issued.
Signaled by auxiliary contact.
The Load cannot be supplied by Automatic Bypass.
K6 closed despite an opening command being
issued. Signaled by auxiliary contact.
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 Technician 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.
K3 open despite a closing command.
Inverter is switched OFF.
It can be restarted manually after recovery of the
K3 not open despite an opening command.
Be aware the DC Capacitors could remain charged.
The Load supplied by Utility exceeds the Inverter
power.
The Load remains supplied by Utility until the alarm
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
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.
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%.
INVERTER AND UTILITY
NOT SYNCHRONIZED
The voltages of Utility and Inverter are not
synchronized, which causes the opening of K6.
The propagation of the eBoost / IEMi configuration
to other units in a Parallel System failed.
