5.4 Alarm setting

E.g. To set No. 1 relay output as over voltage alarm, set pulse width as 10.0s, set alarm value as 120.0%, set

hysteresis value as 5.0%, set alarm delay as 1.0s, the operation process is as follows,

Enter programming interface,
select signal input setting menu

>3s

Set relay working mode as alarm mode Alr

Set relay pulse width as 10.0s

Set alarm item as over voltage alarm

Set alarm value as 120.0% of rated value

Set hysteresis value as 5.0% of rated value

Set alarm delay time as 1.0s
