Alarm Display When You Use External 24 V Power Supply
When you use an external 24 V power supply, an alarm is detected as shown in Table 3.10 if you set o2-23
[External 24V Powerloss Detection] and o2-26 [Alarm display at ext. 24V power] for the main circuit power
supply. Set the alarm display as needed.
