the overtemperature is still detected, the UPS will be completely blocked (rectifier also shut-down)
and the alarm appears.
• Screen 4.61: When the rectifier is overloaded, depending on the level of this overload, the inverter
will be shut down after some time according to the rectifier overload curve (alarm 4.32). If this
overload is still present with the inverter switched off, the UPS will be completely blocked (rectifier
also shut-down) after 30’’, appearing this alarm message.
• Screen 4.62: When any IGBT in the inverter side, desaturates the number of times programmed by
display (200 by default) the inverter blocks. After two more retries this alarm appears indicating UPS
blocked.
• Screen 4.63: After 3 times shutting down the UPS because of (*) DSP Internal Error in the UPS
module, this alarm will appear indicating UPS blocked.
• Screen 4.64: If there is a blocking condition for the inverter and also a blocking condition for the
PFC, this alarm appears blocking also the UPS.
(*) DSP Internal Error can happen for the following reasons:
Wacth Dog failure.
Wrong ADC mesures.
Communication errors between DSP and
uprocessor.
6-3-5. ‘‘DATA LOGGER’’ level (screen menu 5.0). See Fig. 35
• Screen 5.1: Indicates the inverter runtime from the first unit startup. This counter accumulates the
total inverter running time from the beginning and it’s not possible to reset it.
• Screen 5.2: This screen indicates that the data logger is empty. This happen only if authorized
personnel resets this file. If the buffer is not empty, the following screen will inform about the data
logger registers.
(Using the (),() keys, you can move through the different registers of this historic file. The data logger
file can save up to 100 historic registers.
Using the (), () you can see the three different screens per register with the information described
below.
• Screen 5.3: In this screen appears the same information described above in the alarm screens
except the three first characters where there is a register counter from 00) to 99).
• Screen 5.4: This screen is divided in two rows. In the first row there is information about time and
date of alarm activation:
hh: hour of alarm activation
mm: minutes of alarm activation
ss: seconds of alarm activation
dd: day of alarm activation
mm: month of alarm activation
yy: year of alarm activation
In the second row there is information about time and date of deleted alarm
