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 "-".
SETTING= values of relay's operation parameters as programmed; the setting program actually active is
displayed with steady light whereas the stand-by program is displayed with flashing light.
F
RELAY= output relay associated to the different functions as programmed.
