OPM_LPS_3UO_30K_40K_0US_V010.doc Operating Manual LP 33 Series 30 & 40 kVA
Code Alarm Meaning
4520
NO INVERTER
POWER
The load supplied by utility is over 100%.
The load remains blocked on utility as long as alarm
overload is active.
4530
LOAD LOCKED
ON MAINS
Load is locked on mains because 3 transfers on mains have
been detected in a short time (default 30 seconds).
Transfer will be free again after a time defined by respective
parameter (default 30 seconds).
4531
LOAD ON MAINS
BY ERROR DETECTOR
Load is transferred to mains because the error detector
detected a disturbance on the output voltage.
4563
EMERGENCY OFF
ACTIVATED
Alarm after detection of an Emergency Off from an external
safety device connected on Customer Interface.
Consequently K4, K6 and K7 open and shut down inverter,
booster and rectifier.
4570 OVERLOAD
The UPS-System is in an overload condition >125% on
inverter, or >150% on mains.
A sequence of “stop operation” starts.
Time out depending on load quantity.
4571
OVERLOAD:
LOAD ON MAINS
With mains bypass supply available and load >115%, the
load is transferred on mains.
Load will be transferred again automatically on inverter
when load will be <100%.
4581
INVERTER AND
MAINS NOT SYNCH.
The voltages of mains and inverter are not synchronized,
which causes the opening of K6.
4697
BATTERY
OVERTEMPERATURE
The battery temperature exceeds the value inserted in
parameter.
Disabled with parameter (service only).
4698
BATTERY POWER
INSUFFICIENT
In case of utility failure, with the actual load, the autonomy
time would result below “stop operation” time (default 3
minutes).
4700 DC LOW
Battery voltage is at the lowest limit.
Shutdown of inverter until the battery voltage reaches the
value in respective parameter.
4900
LOAD LOCKED
ON INVERTER
The load is locked on Inverter following 3 load transfers
within 30 seconds.
After time out of the value in respective parameter (default
30 seconds), bypass will be free.
4955 OVERTEMPERATURE
An overtemperature condition has been detected on
inverter.
Elapsed “stop operation” time, inverter shutdown.
With mains available, load is transferred on mains.
4998
LOAD OFF DUE TO
EXTENDED 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
UBATT OR TEMP.
Load Off after time-out of “stop operation” with missing
mains due to battery low voltage or overtemperature
condition.
