Figure 4-1: Shuttle Knob
The shuttle knob is located to the right of the LCD screen and is used to change setup
parameters. Note that it cannot be used to move the cursor position between menu fields. Use
the UP and DOWN arrow keys in the FUNCTION keypad for this.
The shuttle knob can operate in one of two distinct modes of operation:
MODE DESCRIPTION
IMMEDIATE mode Any time the ENTER key is pressed, the i/iX Series returns to its
normal mode of operation. In this mode, changes made with the
shuttle knob or the data entry keypad will take immediate effect.
The IMMEDIATE mode is useful for slewing output values such
as voltage and frequency and observing the effect on the load.
SET mode When the SET key located in the FUNCTION keypad is
pressed, changes made with the shuttle to any output parameter
will not take effect until the ENTER key is pressed. In this mode,
any changes made to a setup menu will be blinking to indicate
the pending change condition. This mode allows changes to be
made to all output parameters and executing them all at once by
pressing the ENTER key.
