Preface

GP-2400/2500/2600 Series User Manual 5

• Do not create switches used to control machine safety

operations, such as an emergency stop switch, as a GP

touch screen icon. Be sure to install these switches as

separate hardware switches, otherwise severe bodily

injury or equipment damage can occur.

• When using the GP with transportation vehicles (trains,

cars and ships), disaster and crime prevention devices,

various types of safety equipment, non-life support re-

lated medical devices, etc. redundant and/or failsafe sys-

tem designs should be used to ensure the proper degree

of reliability and safety.

Touch Panel

• After the GP’s backlight burns out, the touch panel is still

active. If the operator fails to notice that the backlight is

burned out and touches the panel, a potentially danger-

ous malfunction can occur.

If your GP’s backlight suddenly turns OFF, use the follow-

ing steps to determine if the backlight is actually burned out.

1) When the backlight burnout feature

is not set, and

the screen has gone blank, your backlight is burned

out.

2) When the backlight burnout feature

is set, and the

screen has gone blank, if touching the screen does

not cause the backlight to tourn ON, your backlight is

burned out.

It is recommended to use the feature that disables the

device operation to prevent accidental machine

misoperation when a backlight burnout is detected auto-

matically.

Wiring

• To prevent electrical shock or equipment damage, unplug

the GP unit’s power cord from the power supply prior to

installing or wiring the GP.

• After completing any GP wiring work, be sure the terminal

block’s protective plastic cover is reattached. If this

cover is not reattached, an electrical shock could easily

occur.

• Do not use power beyond the GP’s specified voltage

range. Doing so may cause a fire or an electric shock.
