Controls Interface
Setpoint Screen
The setpoint screen is a two-part
screen. Screen 1 lists all setpoints
available to change along with their
current value. The operator selects a
setpoint to change by touching either
the verbal description or setpoint value.
Doing this causes the screen to switch
to Screen 2.
In Screen 1 the language setpoint will
always be the last setpoint in the list.
This will facilitate language changes
by placing that control in a standard
position across all CH.530 product
lines.
Screen 2 displays the current value
of the chosen setpoint in the upper
½ of the display. It is displayed in a
changeable format consistent with its
type. Binary setpoints are considered
to be simple two state enumeration and
will use radio buttons. Analog setpoints
are displayed as spin buttons. The
lower half of the screen is reserved for
help screens.
