•
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 remains
after another 1 minute with the rectifier running, rectifier is also
shutdown (alarm 4.71).
•
Screen 4.37
: This alarm is displayed when the rectifier is over-
loaded and depending on the level of this overload, the inverter
is shut down after some time according to the rectifier 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 in-
verter.
•
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
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 shutdown,
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 im-
mediately. 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 bat-
teries, in case of internal over temperature detection, the oper-
ating 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 rectifier
due to desaturations, this alarm will be displayed indicating 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.
•
Screen 4.56
: After several times shutting down the rectifier
because of (*) DSP Internal Error in the rectifier module, this
alarm will be displayed indicating rectifier blocked.
•
Screen 4.57
: During the start up there is an input contactor
test. If this test ends unsuccessfully the rectifier will be blocked.
•
Screen 4.58
: If Inverter voltage ramp is not done properly after
several attempts, it will be blocked (see screen 4.42).
•
Screen 4.59
: This alarm appears when there is an offset
voltage higher than 8V, in any phase of the inverter output
(phase to neutral voltage). Next the inverter is blocked.
•
Screen 4.60
: This alarm is displayed when the UPS is blocked
for any reason. Also this condition blocks the inverter.
•
Screen 4.61
: After several times of shutting down the inverter
due to desaturations, this alarm will be displayed indicating inverter
blocked.
•
Screen 4.62
: There is a command from the microprocessor
to the inverter DSP, with no response. The inverter is blocked.
•
Screen 4.63
: After several times shutting down the inverter
because of (*) DSP Internal Error in the inverter module, this
alarm will be displayed and the inverter is blocked.
•
Screen 4.64
: After several attempts detecting “Inverter Fault/
Overload” (see screen 4.41), the inverter is blocked perma-
nently, and output is transferred to bypass.
•
Screen 4.65
: This alarm is displayed when the rectifier is
blocked for any reason that also blocks the UPS.
•
Screen 4.66
: The alarm is displayed when the DSP doesn’t
response to the microprocessor during the initial procedure be-
fore starting up.
•
Screen 4.67
: There is a command from the microprocessor
to the UPS module DSP, with no response. The UPS is blocked.
