11. READING OF PROGRAMMED SETTINGS AND RELAY'S CONFIGURATION
Enter the mode "SET DISP", select the menu "SETTINGS" or "F
RELAY", scroll information
available in the menu by keys "+" or "-".
SETTINGS= values of relay's operation parameters as programmed
F
RELAY= output relays associated to the different functions as programmed.
12. PROGRAMMING
The relay is supplied with the standard default programming used for factory test. [ Values here below
reported
( ----- )
].
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
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.
