12. PROGRAMMING 

 

The relay is supplied with the standard default programming used for factory test. [ Values here below 
reported in the “ Display “ column ]. 
All parameters can be modified as needed in the mode PROG and displayed in the mode SET DISP 

Local Programming by the front face key board is enabled only if no input current is detected 
(main switch open). Programming via the serial port is always enabled but a password is 
required to access the programming mode. The default password is the null string; in the 
standard appl

ication program for communication “MS-COM” it is also provided an emergency 

password which can be disclosed on request only. 

As soon as programming is enabled, the Led  PRG/IRF flashes and the reclosing lock-out relay  R5 is 
deenergized.  Enter  MODE   "PROG" and  SELECT either "SETTINGS" for programming of parameters 
or "F

RELAY" for programming of output relays configuration; enable programming by the indirect 

operation key PROG. 
The key SELECT now scrolls the available parameters. By the key  (+) , (-)  the displayed values can be 
modified; to speed up parameter's variation press the key SELECT while "+" or "-" are pressed.    
Press key "ENTER/RESET" to validate the set values.
