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 dis-
play. 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. Ana
-
log setpoints are displayed as spin buttons. The lower half of the screen is reserved
for help screens.
