Alarm
Description
4400
BYPASS FUSES FAILURE
Auxiliary contact signal (normally closed)
indicates that one fuse of the bypass mains
(F16/17/18) is open.
4404
K6 CLOSING FAILURE
K6 open despite a closing command being
issued. Signalled by auxiliary contact.
The Load cannot be supplied by Automatic
Bypass.
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.
Only a GE Service Engineer can reset the alarm.
4410
BYPASS MAINS OUT OF TOLERANCE
The Mains Bypass Voltage is out of the tolerances
(
10%).
K6 opens, synchronization with Mains is inhibited
and transfer to Mains 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 Mains exceeds the Inverter
power.
The Load remains supplied by Mains until the
alarm stays ON.
4522
FAN FAILURE
The Fan Control Board indicates a malfunction of
one or more ventilators.
4530
LOAD LOCKED ON MAINS
Load is locked on Mains because 3 transfers on
Mains 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 MAINS BY ERROR DETECTOR
Load is transferred to Mains 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 Mains.
With Mains unavailable, a sequence of
“stop
operation”
starts.
Time out depends on degree of overload.
