Fig. 4.Example of part of the main and submenus for the settings of the overcurrent and earth-fault
relay module SPCJ 4D29. The settings currently in use are in the main manu and they are displayed
by pressing the STEP push button. The main menu also includes the measured current values, the
registers 1...9, 0 and A. The main and second setting values are located in the submenus and are
called up on the display with the PROGRAM push button.
