Controller watchdog
Internal system error
SPI Time out
Internal system error
Flash memory corrupted
Internal system error
Power supply fault
Internal system error
Preload time-out
The DC capacitors could not be preloaded in an acceptable time
Real time clock problem
Internal system error
Several units same id
Two or more units have the same CAN_ID (settings of the S5 dip
switches (1 to 3) on the control board
Different firmwares
Different units in a inverter system have different control
firmwares (DSP and/or microcontroller)
Int. BMS fault
Fault coming from Battery Monitoring System
BMS com. watchdog
If the setup where the inverter is communicating with the BMS is
chosen, the watchdog error can triggered if the communication
with the BMS is lost
BMS not ready
If the setup where the inverter is communicating with the BMS is
chosen, this error is triggered if the BMS is not answering at the
startup of the system (power is supplied to the control)
BMS cont. trip
Trip of the DC contactor
For guidelines on how to troubleshoot and solve the reported problems, refer to
Chapter 11.
−
For multi-unit inverters, this data can be obtained for each individual unit.
−
Internal system errors are most likely due to faulty hardware and thus the only
solution may be to exchange the controller cards.
−
If the message ‘IGBT check cooling’ appears, this implies that the system is
stopped due to an over temperature problem.
In that case, check the cooling of the system (fans, inverters) and of the switchgear
room (air conditioning system etc.)
After the problem is solved the system has to be manually reset (fault
acknowledgement) before normal operation can be resumed.
−
In general the occurrence of transient faults is no problem for the proper
operation of the active inverter. Only when an error becomes ‘critical’, a problem
may exist.
A fault is considered critical if after occurrence, it cannot be successfully
automatically cleared by the system within a reasonable time. The time frame
considered depends on the error type.
