Push-button Operations

Use the RESET/STEP push-button to:- reset operation indicators- step forward or backward in main menus or submenus- set adjustable parameter values when in the setting mode

Use the PROGRAM push-button to:- enter a submenu from the main menu- enter the setting mode of an adjustable parameter- control the cursor in the setting mode or to control the selected output in the test mode

Use both push-buttons simultaneously to:- make a complete relay reset, i.e. erase recorded values and release latched output relays- save a new setting value- carry out an output relay test
