6.2.21  Power threshold function at bus restoring 

The

 

“Power threshold function at bus restoring”

 parameter enables the power threshold function following 

a BUS voltage reset. The possible values are: 
 

-

 

deactive 

 

 

 

 

 

 

 

-

 

active  

 

 

 

 

 

  

-

 

as before voltage dropping 

 

 

 

 

(default value) 

 
 
With 

deactive

, the power threshold function is not activated when the BUS voltage is reset. 

 
With 

active

, the power threshold function is enabled with the current value. 

 
With 

as  before  voltage  dropping

,  the  threshold  activation  status  in  force  prior  to the  failure  is  maintained 

when the BUS voltage is reset.
