■ If a Power Failure Occurs during Operation
● Momentary Power Failures shorter than 20 ms
The indicator is not affected at all and continues normal operation.
● Momentary Power Failures of 20 ms or longer
• The alarm function of the indicator continues to work normally. (Alarms with the stand-
by feature temporarily return to their stand-by state, however.)
• Setting parameters that have already been configured retain their settings.
