information is displayed on the operational panel and even the failure is to be shielded.
Unit place, tens place, hundreds place and thousands place displayed on operational panels from PA.16
to PA.18 can be set:
0: Failure not shielded and alarm and stop during failure.
1: Failure not shielded and alarm but not stop during failure.
2: Failure shielded, neither alarm nor stop.
