Figure 4-2: Shuttle Knob
The i /iX Series has a single rotating knob (“shuttle”). This shuttle knob is located to the right of the
numeric keypad. This knob may be used to continuously vary parameter values or select from multiple
settings in a given menu field. The parameter or field affected by turning the shuttle knob is indicated
by a left pointing arrow (cursor) on the LCD display. Note that it is not possible to move this cursor
position between menu fields using the knob. Use the UP and DOWN arrow (cursor) keys for this
instead. Data and parameter entry can also be done through the numeric keypad.
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 power source returns to its
normal mode of operation. In this mode, changes made with the
shuttle knob will take immediate effect. The IMMEDIATE mode is
useful for continuously varying output values such as voltage and
frequency and observing the effect on the load.
SET mode When the Set key is pressed again while the PROGRAM screen is
already displayed, 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 have a blinking cursor
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.
