(5) Action selection at input error (AEo1, AEo2, AEo3)
Set the alarm action in input abnormality by input break (when the input is over-scaled or
underscaled).
Details of setting Factory set value
0000 Normal processing:
The alarm action set by alarm type selection (AS1/AS2) is taken
even if the input is abnormal.
0000
0001 Forcibly turned on when abnormal:
The alarm is forcibly turned on regardless of the alarm action set
by alarm type selection (AS1/AS2) when the input is abnormal.
For a voltage input of 0 to 5 V DC or 0 to 10 V DC, as over-scale or underscale does not
occur when the input breaks, no alarm is turned on.
