OVERLOAD
Description
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 Engineer can reset the alarm.
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
alarm condition.
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
stays ON.
The Fan Control Board indicates a malfunction of
one or more ventilators.
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.).
Load is transferred to Utility 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 Utility.
With Utility unavailable, a sequence of "stop
operation" starts.
Time out depends on degree of overload.
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%.
The voltages of Utility and Inverter are not
synchronized, which causes the opening of K6.
The propagation of the SEM / IEMi configuration to
other units in a Parallel System failed.
