Screen 4.29: This alarm can be displayed for two reasons:
•
Input contactor from the equipment faults (it doesn't close
ˆ
properly). It is shown when the DC bus voltage, it is not
kept at certain level when turning on such input contactor.
If for any reason, during the initial start up of the inverter,
ˆ
with the input contactor closed and rectifier still shut-
down, it is detected a wrong inverter voltage or it is not
able to start up.
The system can retry the contactor test several times (see de-
scription of the screen 4.57 too).
Screen 4.30: This alarm is displayed when the quantity of
•
IGBT desaturations in the inverter, reaches its set limit.
Screen 4.31: When the inverter output is overloaded, it is dis-
•
played this alarm. Depending on the level of this overload, the
inverter will be shut down after some time according to the
UPS overload curve.
Screen 4.32: When a shutdown is enabled by an external
•
signal, the inverter is shut down and it is displayed this message.
Screen 4.33: When the inverter is running and the mainte-
•
nance bypass switch is turned ON the inverter is shutdown
immediately.
Screen 4.34: This alarm appears when, in a parallel system,
•
one UPS goes to battery mode. The inverter will shut down.
Screen 4.35: This message indicates that one UPS of the par-
•
allel system is running over 160% of load.
Screen 4.36: When an overtemperature is detected by the
•
PFC or inverter temperature probes, after 1 minute the inverter
is turned off automatically. If overtemperature condition re-
mains after another 1 minute with the rectifier running, recti-
fier is also shutdown (alarm 4.71).
Screen 4.37: This alarm is displayed when the rectifier is
•
overloaded and depending on the level of this overload, the
inverter is shut down after some time according to the rec-
tifier overload curve. If this overload is still present with the
inverter turned off, the rectifier will be blocked after 30'' and
the blocking alarm 4.72 will be displayed.
Screen 4.38: This alarm is displayed when there is a (*)
•
DSP Internal Error in the inverter module, shutting down the
inverter immediately. There will be several retries before
blocking the inverter.
Screen 4.39: This alarm is displayed when an output short-
•
circuit is detected, limiting the output RMS current up to the
set value (150% of nominal current by default). The short-
circuit is detected when the output voltage phase to neutral
is lower than 16 % of nominal voltage. The system will retry
twice to restart up.
Screen 4.40: With the inverter running, if there's a wrong by-
•
pass phase rotation, the inverter will be shutdown.
Screen 4.41: This alarm can be activated due to a connection
•
of a load with high inrush current, or also, if it is detected a
wrong transient voltage in the inverter (i.e., if there is a fault in
an inverter transistor). In such case, the inverter will be shut-
down for while and load will be transferred to bypass immedi-
ately. The equipment will retry to start up the inverter several
146
times (see description of the screen 4.64 too).
Screen 4.42: The way to start up the inverter is on voltage
•
ramp mode (rms value from sinewave voltage starts at 0 Vrms
till reaching its preset nominal value, i.e., 230 Vrms). If when
doing the voltage ramp is detected any fault, the inverter will
be shutdown for while, and it will retry to start it up several
times (see description of the screen 4.58 too).
Screen 4.43: In a parallel system, the inverters of the equip-
•
ments of the system connected at the output can be shut-
down, due to the management of system as a whole, therefore
this alarm is displayed.
Screen 4.44: This alarm means that the battery set has
•
reached the level 10.5 V/bat when the equipment is on battery
mode. This is the end of back up time, so the inverter of the
UPS must be shutdown.
Screen 4.45: This alarm is displayed when there is a (*) DSP
•
Internal Error in the UPS module, shutting down the UPS imme-
diately. There will be several retries before blocking the UPS.
Screen 4.45A: Unlike the 4.36, in case that the inverter of
•
the UPS is not started and the PFC-rectifier is charging the
batteries, in case of internal over temperature detection, the
operating of itself has to be shutdown. It will mean a total
shutdown of the UPS (Rectifier and Inverter shutdown).
Screen 4.46: This alarm is displayed when a combined shut-
•
down of the PFC-rectifier and inverter has been done at the
same time (due to different reasons).
Screen 4.47: In parallel system, the equipments of the system
•
connected at the output can be shutdown (complete shutdown
of the rectifier and inverter), due to the management of system
as a whole, therefore this alarm is displayed.
Screen 4.48: The EPO (Emergency Power Off) button is
•
pressed. The UPS and the static bypass are turned off and no
AC voltage is present at the output.
Screen 4.49: This alarm is displayed after 3 start up retries after
•
detecting an output short-circuit. Then the UPS and the static
bypass are turned off and no AC voltage present at the output.
Screen 4.50: This alarm is displayed when there is a (*)
•
DSP Internal Error in the UPS module, after stopping several
times the UPS. The UPS blocks including the bypass, so no AC
voltage present at the output.
Screen 4.51: After several consecutive attempts, it is de-
•
tected a wrong DC bus voltage (see screen 4.27), rectifier will
be blocked permanently by displaying this alarm.
Screen 4.52: This alarm is displayed when the UPS is blocked
•
for any reason. Also this condition blocks the rectifier.
Screen 4.53: After several times of shutting down the rec-
•
tifier due to desaturations, this alarm will be displayed indi-
cating rectifier blocked.
Screen 4.54: If an error in the initial rectifier ramp is detected
•
during the PFC start up, this alarm will be displayed blocking
the rectifier.
Screen 4.55: There is a command from the microprocessor
•
to the rectifier DSP, with no response. The rectifier is blocked.
