Storage, Handling & Installation
Series FT
Below are some general precautions for the 5-wire & 4-wire touch screen devices. Please check web site for complete documentation.
Installation (4-wire, 5-wire)
• Do not pull on the tail. Do not apply stress to the tail area.
• Avoid vibration or shock.
• The touch screen mounting should not be loose.
• Ensure there are no burrs around the edges of the case or housing that can cause false actuation. The edges of the case or housing should
not enter the keying area.
• The case or housing and upper electrode should have a space of about 0.5 mm to accommodate expansion or shrinkage due to humidity
variances. If a shock barrier is used do not press hard on the upper electrode area. Any shock barrier should be installed more than 0.6
mm above the screen.
• To secure the touch screen, secure the lower portion with an item such as the LCD display panel. Do not secure the upper electrode with
double-sided tape or similar items to avoid stress that can damage the upper or lower electrode.
• In order to balance upper and lower pressure, an air vent may be installed. Ensure that no liquid or oil will enter into the device.
Handling Precautions (4-wire, 5-wire)
• When opening product, take precaution with up/down and front/back directions. Glass edges are not chamfered, corners or edges can
be sharp. Wear gloves when handling the product.
• Do not pick up the product by the tail or pull the tail area.
• Use gloves or finger cots to prevent fingerprints on surface.
• When handling the product, hold it outside of the viewing area.
• Avoid stacking multiple products or placing other items on the product.
• Remove protective film after installation is completed.
Operating Precautions (4-wire, 5-wire)
• Only operate with fingers or a touch screen stylus.
• Do not press hard with pen or similar objects between viewing area and key area.
Design Precautions (4-wire, 5-wire)
• With analog type, resistive value change can dislocate the input area. Input area can be calibrated with software.
• When installing on top of a LCD, noise from the display device can create misoperation. To avoid noise, implement actions such as
grounding the display device frame.
• Do not create software for two point touch as analog type will read the center point between two touch points.
• When used to draw a line, analog type will have a break at dot spacer. Compensate for this with software.
Other Precautions (4-wire, 5-wire)
• Clean with a soft cloth and ethanol. Do not use any cleaning agents other than ethanol.
• Store product in original package and store at the temperature and humidity range specified.
• Do not store in an environment with acids or other corrosive gases or dew.
• Not suited for use in critical control systems such as nuclear power, aerospace, medical or transportation equipment, without
proper failsafe design consideration.
Handling Precautions (5-wire)
• NKK warrantees the 5-wire touch panel when it is used with the NKK control board and driver. Do not use third party control boards.
• 5-wire devices can misalign cathode position or touch position even after calibration. See web site for details.
• Create a larger input area. If you have the input button at the edge of a screen, it might not operate properly.
• Complete 9 point calibration with NKK driver. If more precision is desired, 25 point calibration is recommended.
L
Handling of Controller Board (5-wire)
• Warranty for one year after delivery. We do not warrantee the controller board unless used with NKK touch panel.
• Use arc prevention to protect device from static electricity.
• Power source should be activated after host and touch panel are connected.
• When inserting connector CN1 and touch panel tail, be sure the slider of connector CN1 is pulled. Do not pull more than 10 times.
• Do not alter the product.
• Do not use any commands other than the ones specified in specifications.
• Place the product away from noise source (such as inverter from LCD operation) since tail can be affected by noise.
• If device driver (USB) does not work after installation, reboot the host computer while connected to the controller board.
• This product does not support suspended mode (USB).
• Protocol of USB transmission is one frame per one transaction.
• Contact factory if not using protocol above.
