Alarms
NEEDED
DC LOW
FAILURE
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
synchronized, which causes the opening of K6.
The propagation of the eBoost / IEMi configuration to
other units in a Parallel System failed.
Notice to replace the Lithium Battery located on the P3
- IM0007 Control Board.
Notice to replace the DC Capacitors.
Notice to replace the AC Capacitors.
Notice to replace the Fans.
Notice to do the Service Maintenance.
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.
