Codes
Code Description
Communication with power module is
401
not possible
406 DC module temperature sensor faulty
407 AC module temperature sensor faulty
408 Direct component measured in the sup-
ply grid too high
The "fixed voltage" setting has been se-
lected instead of MPP voltage operation
412
and the voltage is set to a value that is
too low or too high.
415 Safety cut-out triggered by option card or
RECERBO
No communication between power mod-
416
ule and control unit
417 ID problem with hardware
419 Unique ID conflict
421 HID range error
425 Communication with the power module
is not possible
426 -
