6.2 Error indication on the displays
Switch-off (shutdown of the module) caused by error is indicated on the displays.
Example:
Upper display:
SHd = Shutdown
Lower display:
Error number (example „129“)
Possible single error numbers are listed in the table below:
Error number (decimal number)
Meaning
1 I
o
> or Vi>
2
Vi< or fan error
4
Vo not ok (e.g. restart error)
8
T> or input DC/DC converter not ok
16 Internal
error
32
Switch off via CAN-Bus (e.g. by static bypass switch UNB)
64 Vo>
128 Vo<
If more than one error appeared, the result (addition of the single error numbers) is shown at the lower display.
The example above (error number „129“) is the result of error number „1“ plus error number „128“.
For error numbers which include two possibilities (error number „1“, „2“ and „8“) please note the LED which
additionally is “ON” for an identification of the error.
A further example to clarify:
Upper display:
SHd = Shutdown
Lower display:
Error number (example „138“)
Error number „138“ is the result of „128“ + „8“ + „2“.
„2“ means “input under voltage” (LED „Vi<“ is ON) or “fan error” (LED „T>“ is blinking).
„8“ means “over temperature” (LED „T>“ is ON) or “input DC/DC converter is not ok”.
„128“ means „output under voltage”. Because the module has switched OFF there is no output voltage. Due to
this, the error „output under voltage“ also is included.
