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.
