Depending on the current trouble, faults are managed differently (different error levels):
LEVEL 0 : Warning without STOP
Trouble is displayed with a warning number xx in the LED display (nxx). Additionally a warning bit is set in the status register, that can be reported with a digital output. The output stage remains enabled, the amplifier remains ready to operate, but the operation may be reduced (current limitation). Reduction of operation will disappear as soon as trouble disappears.
