KEYPAD FUNCTIONS
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; and in Alarm mode, it
displays an alarm code which identifies the alarm 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 value of the PID
command, not the frequency data usually displayed.

Simultaneous keying
Simultaneous keying means pressing two keys at the same time. The FRENIC-MEGA supports
simultaneous keying as listed below.
The simultaneous keying operation is expressed by a "+" letter between the keys throughout this manual.
(For example, the expression "
+ keys" stands for pressing the key while holding down the
key.)
