Reset actuator with pushbutton 1. Press button > 10 s a LED flashes orange 2. Release the button while LED is still flashing a LED flashes another 3 s 3. Press button within these 3 s a Reset is cancelled 4. Press button after these 3 s a LED is red (Reset) while the device restarts. Enter address using pushbutton Display current address (starting from lowest address position) The Modbus address can be set without an extra tool using pushbutton addressing.
