Overview Chapter 1
Operator Input
All 700 to 1500 display modules have TFT color, graphic displays with either
keypad, touch screen, or combination keypad/touch-screen input. Common
features and firmware provide for easy migration to a larger display:
• Eight-wire resistive touch screens are extremely accurate for operator
interfaces. When a point on the touch screen is pressed, the layers connect
and change the electrical current, which is then registered and processed.
• All keypad or combination keypad/touch-screen displays are similar except
for the number of functions keys.
To meet the requirements of specific environmental conditions, high-bright
displays, marine-certified displays, and conformal-coated displays are also
available. Plus, you can order field replaceable bezels.

ATTENTION: Use a finger or gloved finger to operate the keypad. To operate the
touch screen, use a finger, gloved-finger or plastic stylus with a minimum tip
radius of 1.3 mm (0.051 in.). Using any other object or tool can damage the
keypad or touch screen.
ATTENTION: Do not carry out multiple operations simultaneously. Doing so can
result in unintended operation:
• Touch only one operating element on the screen with one finger at one time.
• Press only one key on the terminal at one time.
