The UPS-System is in an overload condition >125% on
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 >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 eBoost / IEMi configuration to other
units in a Parallel System failed.
Detection of Battery over temperature condition.
Can be deactivated by Service Center.
In case of Utility Failure, with the actual Load, the run time
would be below stop operation time (default 3 minutes).
Battery voltage is at the lowest limit.
Will stay Off Inverter until the battery voltage reaches the
value in parameter.
Failure detection on the +24V derived from the DC-link
voltage.
The Load is locked on Inverter after 3 Load transfers within
30 seconds.
After time out (default 30 seconds) Bypass will be free.
An over-temperature condition has been detected on
Inverter.
Elapsed "stop operation" time, Inverter shutdown.
With Utility OK, Load is transferred on Utility.
Load Off after time-out of "stop operation" for overload on
Inverter or Bypass (time depending on the % of overload).
Load Off after time-out of "stop operation" with missing
Utility due to Battery low voltage or over-temperature
condition.
