Preface
WARNINGS
• 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. Therefore, do not use GP
touch switches for the control of any equipment safety
mechanisms, such as Emergency Stop switches, etc. that
protect humans and equipment from injury and damage.
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.
GP Wiring
• To prevent an electric shock, be sure to confirm that the
GP’s power cord is not connected to the main power
when connecting any cords, cables or lines to the GP.
• Do not use power beyond the GP’s specified voltage
range. Doing so may cause a fire or an electric shock.
GP Start-up and Maintenance
• The GP uses a lithium battery for backing up its internal
clock data. If the battery is incorrectly replaced, the bat-
tery may explode. To prevent this, please do not replace
the battery yourself. When the battery needs to be re-
placed, please contact your local GP distributor.
