Select the value to be set in H1-oo from a combination of any of the following three conditions:
• Signal input level from peripheral devices (N.O., N.C.)
• External fault detection method
• Operation after external fault detection
An “On-Delay” timer will be applied to the external fault if it is “Normally Open” and an “Off-Delay” timer will be applied
to the external fault if it is “Normally Closed”.
If the external fault is set to “During Run”, the time delay will start after the Run command is received.
Refer to Figure 5.46 to Figure 5.48 for details.
Table 5.21 shows the relationship between the conditions and the value set to H1-oo:
Terminal statuses, detection conditions, and stopping methods marked with an “O” are applicable to the corresponding settings.
