LED monitor
In Running mode, the LED monitor displays running status information (output frequency, current
or voltage); in Programming mode, it displays menus, function codes and their data; in Alarm mode,
it displays an alarm code which identifies the error factor if the protective function is activated.
If one of LED4 through LED1 is blinking, it means that the cursor is at this digit, allowing you to
change it.
If the decimal point of LED1 is blinking, it means that the currently displayed data is a PID process
command, not the frequency data usually displayed.
