Integrated LCD Display/Keypad Option
ControlWave ExpressPAC offers a convenient local
operator interface. The 2-button display allows an
operator to view site, conguration and process
data. The screens are organized in a series of lists.
The operator can select a list and then manually
scroll through the data. Additionally, a “scroll list”
can be dened. The ControlWave ExpressPAC can
be set to automatically sequence through this list.
The 25-button Display/Keypad performs the same
functions and additionally allows the operator to
view and modify ControlWave ExpressPAC inputs,
process variables, calculated variables, setpoints,
tuning parameters, and outputs used in a measure-
ment or control application. Status bits include
the alarm state, alarm acknowledge, control, and
manual (Auto/Man). Providing access to such vari-
able information allows the user complete control
over the process operation.
The standard LCD provides 4 line x 20 character
display with either a two-button read-only or 25-but-
ton read-write keypad. Both display/keypad assem-
blies have the same “footprint” on the front door.
