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 application 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 alarm relay R5 is deenergized..
Enter MODE "PROG" and SELECT either "SETTING1" or "SETTING2" 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.
