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 sec.
After 3 times K6 remains definitively open.
The alarm reset can be done only from Service.
K8 not closed despite a closing command being issued.
Signaled by auxiliary contact.
The Load cannot be supplied by Automatic Bypass.
K8 closed despite an opening command being issued.
Signaled by auxiliary contact.
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.
A malfunction on the UPS ventilation system was detected.
No change for UPS operation.
Call immediately Service Center for intervention.
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 from an external safety
device connected on Customer Interface Board.
Consequently K3, K4, K6, K7, K8 open, Rectifier, Inverter and
SSM are switched Off.
The UPS-System is in an overload condition
Inverter, or 150% on Utility.
With Utility unavailable, a sequence of "stop operation" starts.
Time out depends on Load quantity.
With Utility Bypass supply available and load
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.
