XPERT-PRO – Operational Manual 

 

TRINITY 

[25]

 

 

 
 

 

 
 
In case of PF, the hysteresis is not applicable and the operation is also reversed. It 
has  a  multiplying  factor  (MF)  of  100.  Thus,  a  PF  value  of  0.98  is  set  as  98.  Thus, 
when the PF value falls below 98, the relay will wait for 120 seconds and then close 
the  switch.  However,  the  relay  will  open  when  PF  crosses  98  with  the  specified 
delay.  
 

Communication

 

 

 

 

RS485 CONNECTION

 

 
The  industrial  standard  RS-485  communication  port  option  is  also  available  in 

XPERT-PRO

.  This  option  makes  it  possible  for  a  user  to  select 

XPERT-PRO

  to 

provide  power  and  energy  information  into  a  variety  of  existing  or  new  control 
systems and communication networks such as EMS/PLC/SCADA.
