4570
OVERLOAD
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.
4571
OVERLOAD: LOAD ON UTILITY
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%.
4581
INVERTER AND UTILITY NOT
SYNCHRONIZED
The voltages of
Utility
and
Inverter
are not synchronized,
which causes the opening of
K6
.
4608
ECO CONFIG FAILURE
The propagation of the
eBoost / IEMi
configuration to other
units in a
Parallel System
failed.
4697
BATTERY OVERTEMPERATURE
Detection of
Battery
over temperature condition.
Can be deactivated by
Service Center
.
4698
BATTERY POWER INSUFFICIENT
In case of
Utility Failure
, with the actual
Load
, the run time
would be below stop operation time (default 3 minutes).
4700
DC LOW
Battery voltage is at the lowest limit.
Will stay Off
Inverter
until the
battery voltage
reaches the
value in parameter.
4701
POWER SUPPLY BOARD
FAILURE
Failure detection on the +24V derived from the
DC-link
voltage
.
4900
LOAD LOCKED ON INVERTER
The
Load
is locked on
Inverter
after 3
Load
transfers within
30 seconds.
After time out (default 30 seconds)
Bypass
will be free.
4955
OVERTEMPERATURE
An over-temperature condition has been detected on
Inverter
.
Elapsed
“stop operation”
time,
Inverter
shutdown.
With
Utility OK
,
Load
is transferred on
Utility
.
4998
LOAD OFF DUE TO EXTENTED
OVERLOAD
Load Off
after time-out of
“stop operation”
for overload on
Inverter
or
Bypass
(time depending on the % of overload).
4999
LOAD OFF DUE
TO LOW BATT. OR TEMP.
Load Off
after time-out of
“stop operation”
with missing
Utility
due to
Battery low voltage
or
over-temperature
condition.
