• Screen 4.68: This alarm is displayed when the inverter is
blocked for any reason that also blocks the UPS.
• Screen 4.69: There is an internal error in the communication channel
between microprocessor and DSP. This condition blocks the UPS.
• Screen 4.70: Unlike the cases 4.27, 4.51, if the DC Bus voltage
is detected meanwhile the PFC-rectifier is not in operation
(equipment discharging the batteries), the UPS has to be shut-
down completely (inverter has to be shutdown too), so as a
result the UPS will be blocked. This phenomena can be due to a
failure of the UPS, or due to an "asymmetrical" consumption of
a load connected at the output of the UPS (with average value
different from 0V, so, with DC level). This type of loads are in-
compatible with the UPS.
• Screen 4.71: When an overtemperature is detected by the
PFC or inverter temperature probes, first the inverter will be
turned off after 1 minute time automatically (alarm 4.36). If 1
minute later the overtemperature is still present, the UPS will
be completely blocked (rectifier also shut-down) and this alarm
is displayed.

• Screen 4.72: When the rectifier is overloaded, depending on
the level of this overload, the inverter will be shut down ac-
cording to the rectifier overload curve (alarm 4.37). If this over-
load is still present with the inverter turned off, the UPS will be
completely blocked (rectifier also shutdown) after 30'', and this
alarm will be displayed.
• Screen 4.73: When the quantity of desaturations of an inverter
IGBT reaches its limit, the inverter is blocked. After two more
retries this alarm UPS blocked is displayed.
• Screen 4.74: After several shutting down retries of the UPS
because of (*) DSP Internal Error in the UPS module, this alarm
will be displayed indicating UPS blocked.
(*) A DSP Internal Error can happen because of the fol-
lowing reasons:
– Watch Dog failure.
– Wrong ADC measurements.
– Communication errors between DSP and micropro-
cessor.
• Screen 4.75: If there is a blocking condition for the inverter
and another blocking condition for the PFC, this alarm will be
displayed and the UPS will also be blocked.
• Screen 4.76: After the first error in the parallel system commu-
nication, when one of the equipments has already been chosen
as a Fix Master in the system, a second error or break in the
communications has been detected by the Slaves equipments,
it will cause to block them permanently (Rectifier and Inverter
are shutdown, no output voltage is supplied to the output of the
system), by displaying this alarm.
• Screen 4.77: Input frequency auto-sensing failure. Equipment
blocked.
This alarm will be displayed, when the input frequency selection
in the installation menu is set to AUTOMATIC mode only and the
input frequency is out of the acceptable range of ±5% respect
to 50 or 60 Hz.
