Faults:
These are more critical problems compared to the “Anomalies”, as if they persist they may bring the CPS to
a halt even in a very short time.

Locks:
these codes indicate that the CPS, or one of its parts, is locked. Usually, they are preceded by an alarm signal.
In case of faults and consequent locking of the inverter, the latter will be turned off and the load will be powered via
the bypass line (this procedure is excluded for locks caused by serious and persistent overloads and for those caused
by a short circuit).
