Pro-face PS-3600G Series User Manual page 4

Be sure to use redundant and/or failsafe system designs to ensure adequate levels of system reliability
and safety when using the PS-G with transportation vehicles (trains, cars and ships), disaster and crime
prevention devices, various types of safety equipment, non-life support related medical devices, and other
similar equipment.
After the PS-G unit's backlight burns out the touch panel is still active, unlike the PS-G 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 PS-G unit touch panel switches
that may cause injury and/or equipment damage.
If your PS-G unit's backlight suddenly turns OFF, use the following steps to determine if the backlight is
actually burned out.
1) If the PS-G unit's "Backlight Control" is not set and the screen has gone blank, your backlight is burned
out.
2) If the PS-G unit's "Backlight Control" is set to Standby Mode and the screen has gone blank, and touch-
ing the screen or performing another input operation does not cause the display to reappear, your back-
light is burned out.
Handling
Do not modify the PS-G unit. Doing so may cause a fire or an electric shock.
Do not operate the PS-G in an environment where flammable gases are present, since it may cause an
explosion.
Wiring
To prevent an electric shock be sure to disconnect your PS-G unit's power cord from the power supply
before wiring the PS-G.
Do not use voltage beyond the PS-G unit's specified range. Doing so may cause a fire or an electric
shock.
Maintenance
Do not connect or disconnect Host and PS-G unit communication cables while the PS-G is turned ON.
The PS-G uses a lithium battery for backing up its internal clock data and the battery may explode if it is
replaced incorrectly. When replacement is required, use a Pro-face-designated replacement or an equiva-
lent product.
