The alarm relay output can be configured as either latch able or non-latch able output. 

  

The  alarm  relay  goes  back  to  inactive  state  as  soon  as  the  alarm  value  falls  below  the  adjusted 

threshold. 

 

 

The alarm relay remains in active state even when the alarm value falls below the adjusted threshold. 

To reset push the Button 

 for 3 sec. After a brownout, the relay falls back into the state before the 

brownout. 

 

 

The relay 3 is free to program to become active state with trip, alarm or both. Following settings are possible: 

 

relay 3 is always switched off 

   

 

relay 3 becomes active with alarm relay 

   

relay 3 becomes active with trip relay 

 

relay 3 becomes active with trip and alarm relay 

 

relay 3 becomes active with trip or alarm relay 

 

 

The relay 3 output can be configured as either latch able or non-latch able output. 

  

The trip relay 3 goes back to inactive state as soon as the trip / alarm value fall below the adjusted 

threshold. 

 

The  trip  relay  3  remains  in  active  state  even  when  the  trip  /  alarm  value  falls  below  the  adjusted 

threshold. To reset push the Button 

 for 3 sec. After a brownout, the relay falls back into the state 

before the brownout.
