• Emergency stop circuits, interlock circuit, limit circuits, and similar safety measures must be provid-
ed in external control circuits.
• For an NY Monitor Link connection, always follow the cable type and connection method specifica-
tions in the manual. Otherwise, communications may be faulty.
Power Supply Design and Turning ON/OFF the Power Supply
• Always use a power supply that provides power within the rated range.
• Do not perform a dielectric strength test.
• Power ON after the DVI cable is connected between the host PC and the product.
• Power ON after the NY Monitor Link cable is connected between the host PC and the product.
• Always check the power supply and power connections before applying power. Incorrect power con-
nections can damage the product or cause burning.
• Always turn OFF the power supply to system before you attempt any of the following.
• Connecting cables
• Connecting or disconnecting the connectors
• Use a DC power supply with a slight voltage fluctuation that will provide a stable output even if the
input is momentarily interrupted for 10 ms. Use a DC power supply with reinforced insulation or dou-
ble insulation. The rated power supply voltage of the product is 24 VDC with an allowable range of
19.2 to 28.8 VDC.
• Do not turn ON the power supply to the product when a part of a human body or a conductive object
is touching the surface of the touchscreen. Doing so will cause the touchscreen functionality to be
disabled. Remove the conductive object and cycle the power supply to restore the touchscreen
functionality.
Operation
• Do not carry out the following operations when accessing a USB device or an SD Memory Card.
• Turn OFF the power supply of the product.
• Press the power button of the host PC.
• Remove a USB device.
• Confirm the safety of the system before using the touch panel.
• Signals from the touchscreen may not be entered if the touchscreen is pressed consecutively at
high speed. Only move on to the next operation after confirming that the product has detected the
previous input of the touchscreen.
• Do not accidentally press the touchscreen when the backlight is not lit or when the display does not
appear. Confirm the safety of the system before pressing the touchscreen.
• Do not use hard or pointed objects to operate or scrub the touchscreen, otherwise the surface of the
touchscreen may be damaged.
• Before you connect a computer to the product, disconnect the power supply plug of the computer
from the AC outlet. Also, if the computer has an FG terminal, make the connections so that the FG
terminal has the same electrical potential on the product. A difference in electrical potential between
the computer and the product may cause failure or malfunction.
• In systems with multiple screens in extended view, an interruption in the video signal of one screen
will cause all windows on that screen to be moved to the primary screen. Make sure that this situa-
tion is properly handled.
