Table 49: Overview of the events that can be recorded
Event
Description
No event
No storable event has occurred yet
Energization
The power has been switched on
System reset
The inverter controller has been reset
Start request
An inverter start has been requested
Stop request
An inverter stop has been requested
Fault (DSP)
The DSP controller has reported a fault
Fault (uC)
The
µ
controller has reported a fault
Fault cleared
A user attempt to clear a fault has been recorded (by validating the ‘ACK.
FAULT’ option on the ESI-Manager
No more fault
The system detects no more faults
Power outage
The system has detected a power outage
Download DSP A DSP controller firmware upgrade (attempt) has been recorded
DSP stop
An internal stop command coming from the DSP controller has been
recorded
From
it can be seen that both the DSP controller and the
µ
controller can record
faults. Where the faults reported by the
µ
controller are predominantly relating to a
control board failure, the faults reported by the DSP relate predominantly to the inverter
interacting with the installation.
gives an overview of the faults that can be
reported by the DSP controller. The list is in alphabetical order.

DSP
fault
message
Description
Bad CT connection
The automatic CT detection procedure has encountered a problem
during the identification process.
Bad Ratings
The DSP has detected an inconsistent set of commissioning
parameters
DC over voltage (SW)
The DC software over voltage protection has been triggered (Cf. the
detailed manuals for limit values).
DC over voltage (HW)
The DC hardware over voltage protection has been triggered.
DC Top over voltage
The DC over voltage protection of the capacitors in the positive stack
has been triggered.
DC Bot over voltage
The DC over voltage protection of the capacitors in the negative stack
has been triggered.
DC under voltage (SW) The DC software under voltage protection has been triggered.
IGBT check cooling
The software IGBT temperature protection has been triggered.
IGBT permanent
The IGBT modules report an error that cannot be cleared by the
system. This error can be due to peak over current or too low control
voltage for the IGBT drivers.
