Screen 4.43
: After 3 times shutdowns of the rectifier for failure and retry, this alarm will appear indicating that
the rectifier is blocked.
Screen 4.44
: If an error in the initial rectifier ramp is detected during the PFC start up, this alarm will appear
also blocking the rectifier.
Screen 4.45
: If there is a command from the microprocessor to the DSP, with no response from the rectifier
module of the DSP, the rectifier will be blocked.
Screen 4.46
: After 4 shutdowns of the rectifier because of (*) DSP Internal Error in the rectifier module, this
alarm will appear indicating that the rectifier is blocked.
Screen 4.47
: During the start up there is an input contactor test. If this test ends unsuccessfully the rectifier
will be blocked.
Screen 4.48
: If the output voltage ramp does not work properly during the inverter start up the inverter will
be blocked.
Screen 4.49
: This alarm appears when there is an offset voltage higher than 8V, in any phase of the inverter
output voltage phase to neutral. The inverter will be blocked.
Screen 4.50
: This alarm appears when the UPS is blocked for any reason. This condition also blocks the
inverter.
Screen 4.51
: After 3 shutdowns of the inverter for failure and retry, this alarm will appear indicating that the
inverter is blocked.
Screen 4.52
: If there is a command from the microprocessor to the DSP, with no response from the inverter
module of the DSP, the inverter will be blocked.
Screen 4.53
: After 5 shutdowns of the inverter because of (*) DSP Internal Error in the inverter module, this
alarm will appear indicating that the inverter is blocked.
Screen 4.54
: This alarm appears when the rectifier is blocked for a reason that may also block the UPS.
Screen 4.55
: The alarm appears when the DSP does not respond to the microprocessor during the initial
procedure before the start up.
Screen 4.56
: If there is a command from the microprocessor to the DSP, with no response from the UPS
module of the DSP, the UPS will be blocked.
Screen 4.57
: This alarm appears when the inverter is blocked for a reason that may also block the UPS.
Screen 4.58
: If there is an internal error in the communication channel between microprocessor and DSP, this
condition blocks the UPS.
Screen 4.59
: This alarm appears when, in a parallel system, one UPS goes into battery mode. After a period
of time, the UPS will shut down.
Screen 4.60
: When an over temperature is detected by the PFC or inverter temperature sensors, first the
inverter will be turned off automatically after 1 minute (alarm 4.31). If one minute later the over temperature is
still detected, the UPS will be fully 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 a certain 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 fully blocked (rectifier also shut down) after 30’’ and an
alarm message appears.
Screen 4.62:
When any IGBT on the inverter side, modifies the number of display times programmed (200 by
default) the inverter blocks. After two more retries this alarm appears indicating that the UPS is blocked.
Screen 4.63:
After 3 shutdowns of the UPS because of (*) DSP Internal Error in the UPS module, this alarm
will appear indicating that the UPS is blocked.
Screen 4.64:
If there is a blocking condition for the inverter and also a blocking condition for the PFC, this
alarm appears also blocking the UPS.
