Critical Power
Auxiliary contact
indicates that one fuse of the bypass mains
(F16/17/18) is open.
K6 open despite a closing command being
issued. Signalled by auxiliary contact.
The Load cannot be supplied by Automatic
Bypass.
K6 closed despite an opening command being
issued. Signalled 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 Engineer can reset the alarm.
The Mains Bypass Voltage is out of the tolerances
( 10%).
K6 opens, synchronization with Mains is inhibited
and transfer to Mains is blocked.
K3 open despite a closing command.
Inverter is switched OFF.
It can be restarted manually after recovery of the
alarm condition.
K3 not open despite an opening command.
Be aware the DC Capacitors could remain
charged.
The Load supplied by Mains exceeds the Inverter
power.
The Load remains supplied by Mains until the
alarm stays ON.
The Fan Control Board indicates a malfunction of
one or more ventilators.
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.).
Load is transferred to Mains because the error
detector detected a disturbance on the output
voltage.
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.
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.
