When using the GP with transportation vehicles (trains, cars, and ships), disaster and crime prevention
devices, various types of safety equipment, and medical devices that are not life-support related, use
redundant and/or failsafe system designs to ensure proper reliability and safety.
After the GP unit’s backlight burns out the touch panel is still active, unlike the GP unit’s “Standby Mode”.
If the operator fails to notice that the backlight is burned out and touches the panel, a potentially
dangerous machine operation error can occur. Therefore, do not create GP unit touch panel switches that
may cause injury and/or equipment damage. If your GP unit’s backlight suddenly turns OFF, use the
following steps to determine if the backlight is actually burned out.
1)
If the GP unit’s “Backlight Control” is not set and the screen has gone blank, your backlight is burned out.
2) If the GP unit’s “Backlight Control” is set to Standby Mode and the screen has gone blank, and touching
the screen or performing another input operation does not cause the display to reappear, your backlight
is burned out.
Do not disassemble or modify the GP unit. Doing so may cause a fire or an electric shock.
Do not operate the GP in an environment where flammable gases are present, since it may cause an explosion.
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.
To prevent an electric shock be sure to disconnect your GP unit’s power cord from the power supply
before wiring the GP.
Do not use voltage beyond the GP unit’s specified range. Doing so may cause a fire or an electric shock.
The cables connected to the GP should be secured by cable clamps to prevent weight or tension of the
cables added to the connectors or terminals.
The GP unit’s wiring should be checked to confirm that both the operating voltage and wiring terminal locations
are correct. If either the voltage or the wiring terminal location is incorrect, it can cause a fire or accident.
NEVER touch a live power terminal. Doing so could cause an electrical shock or a machine malfunction.
To prevent an electrical shock, unplug the GP unit’s power cord before either cleaning the GP or attaching/
detaching the power terminal attachment screws.
Do not connect or disconnect Host and GP unit communication cables while the GP is turned ON.
