ControlWave Micro Display/Keypad Instruction Manual (D5135)
Chapter 1 – Introduction
ControlWave Display/Keypad assemblies provide a built-in, local, user
interface for the following ControlWave models: ControlWave Micro,
ControlWave EFM, ControlWave Express, ControlWave Express PAC,
ControlWave GFC, ControlWave GFC Plus, and ControlWave
Corrector.
These optional assemblies allow an operator or engineer to view and,
depending upon the keypad type, modify, variable values and associated
status information.
Variables can include inputs, process variables, calculated variables,
constants, setpoints, tuning parameters and outputs used in a
measurement or control application. Status bits include alarm state,
alarm acknowledge, control, manual, and questionable data.
ControlWave controllers support two different types of display/keypad
assemblies; one with a dual-button keypad (see Figure 1-1), and one
with a 25-button keypad (see Figure 1-2). Each key has positive tactile
feedback. This means that as you firmly depress the keys, you will feel
it click as it engages. Both display/keypad assemblies utilize identical
four-line by 20 character liquid crystal (LCD) displays.

EXPLOSION HAZARD
When the ControlWave-series controller is situated in a hazardous
location, turn off power before servicing or replacing the unit and before
installing or removing wiring.
Do not connect or disconnect equipment unless the power is switched
off or the area is known to be non-hazardous.
In most cases, the display/keypad assembly arrives factory-installed in
the enclosure.
If you purchase the display/keypad assembly separately, and want to
install it yourself, follow the installation drawings. See Figure 2-1 for
the dual-button keypad, and Figure 2-2 for the 25-button keypad.
Once you’ve installed the display/keypad assembly, connect the display
cable between the RJ-45 jack (J1) on the display/keypad assembly and
the RJ-45 display interface jack on the controller.
2.1 Configuring Your Application to Work with the Display/Keypad
You configure the Display/Keypad in ControlWave Designer by adding
the DISPLAY function block to your project, and configuring its
parameters. The amount of configuration required varies depending
upon the type of keypad (25-button or dual-button) and the operating
mode you choose. See the DISPLAY function block online help pages
in ControlWave Designer for instructions.

Chapter 3 – Using the Dual-Button Keypad / Display
The dual-button display/keypad shows variable information through a
series of lists. The dual-button display/keypad does not support
changing variable values or status information; for that, you must have
the 25-button keypad.
From an opening screen, you enter a list selection screen to select the
list you want to view, and then the display scrolls through the variables
in the list, one at a time, at a user-defined rate so you can view variable
values and status information.
If there is no keypad activity for a certain period of time, scrolling stops
and the display shuts off to conserve power until you press any key.
When you press a key after the timeout the display returns to the
opening screen.
Note: Your application programmer can specify the length of time
before scrolling stops through the iiDisplayBlankTime
parameter in the DISPLAY function block.
Dual-Button The two buttons available are the down-arrow (ITEM) and right-arrow
Keypad (LIST) buttons. Table 3-1 describes the function of these buttons.

Legend Line The words Login and Scroll at the bottom of the screen are on the
legend line. Depending upon which screen is active, the function keys
(that is, key [F1] through [F4]) do different things. The legend line tells
you which function keys are active and their purpose for that particular
screen.
Up to four legends can appear on the legend line. The legend on the far
left corresponds to the current function of the [F1] key. The current
assignment for the [F4] key is on the far right. The current use for keys
[F2] and [F3] are described to the left and right of center. When no
legend appears, that function key is not active on this screen. For
example, in Figure 4-2 only [F1] and [F2] are active.
