If the Warning signal level (see below) is reached in the life test setup, the motor is regular tested for the criteria 10.3.1 to 10.3.3 that prescribe when motor life is finished. Warning signal: The motor is build out from the life test setup if as warning signal the motor current deviates 20% of the initial zero hour value or the audible noise is dramatically increased or if significant interruptions occur in the commutation wave form. 10.3.1 Commutation wave form No blocked interruptions; Motor should start up in all rotor positions with motor voltage of item 4.2 10.3.2 No load current 2 times the max. no load current of sheets 190-4 and5 10.3.3 75-05-23 Bearings Bearing function remains intact Motor assy Supers.
