K3 (when installed) not open despite an opening command
is done, or battery fuses F8 / F9 or switch Q3a not open.
Be aware the DC capacitors could remain charged.
The load supplied by mains is over 100%.
The load remains blocked on mains until alarm overload is
active.
Load is locked on mains because 3 transfers on mains have
been detected in a short time, defined by parameter (default
30 seconds).
The transfer will be free after a time defined by parameter
(default 30 sec.).
Load is transferred to mains 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 K6, SSM (K3) opened and shut down inverter
and Rectifier.
The UPS-System is in an overload condition >125% on
inverter, or >150% on Mains.
With mains unavailable, a sequence of "stop operation"
starts. Time out depends on load quantity.
With mains bypass supply available and load >115%, the
load is transferred on mains.
Load will be transferred again automatically on inverter
when load <100%.
The voltages of mains and inverter are not synchronised,
which causes the opening of K6.
The battery temperature exceeds the value inserted in
parameter.
Disabled with parameter (service only).
In case of mains failure, with the actual load, the run time
would be below Stop operation time (3 minutes).
Battery voltage is at the lowest limit.
Will stay Off inverter until the battery voltage reaches the
value in parameter.
Detection of a failure on the Power Supply Board, in
particular from the DC supply.
Can be enabled or disabled with respective parameter.
A time of lost redundancy superior than specified in
respective parameter was detected.
The load is locked on inverter after 3 load transfers within 30
seconds.
After time out of the value in parameter (default 30 sec),
bypass will be free.
An over-temperature condition has been detected on
inverter.
Elapsed "stop operation" time, inverter shutdown.
With mains OK, load is transferred on mains.
"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
mains due to battery low voltage or over-temperature
condition.
