Probable Faulty Locations
1)Program sequence at which the alarm has occurred
Code 3->VTOFX[1,2,3]=4.5->In this case, alarm of code 5 occurs due to the relationship between the level and the number of operators.
Code 5->VTOFX=4.5 (Mainly, code 5 is displayed when an alarm occurs.)
Code 6->Alarm of this code number does not occur. Since the end code is always specified at the end of the commands, processing is performed for the data preceding it. Thus the alarm code corresponding to such error to “5”.
