Essential Safety Precautions

This manual includes procedures that must be followed to operate the DU cor­rectly and safely. Be sure to read this manual and any related materials thoroughly to understand the correct operation and functions of this unit.
Icon Meaning
Throughout this manual, the following icons are provided next to operations requiring special attention to allow you to use the DU safely. The operations described with these icons contain essential safety information. The following is an example of these icons and their meanings:
Indicates situations where severe bodily
W arning
injury, death or major equipment damage can occur .
Caution
Indicates situations where slight bodily injury or machine damage can occur.
WARNINGS
System Design
• Before connecting the DU's power cord terminals to its terminal block, be sure the power cord is disconnected from the power supply.
• Do not use power that is beyond the DU's specified volt­age range. It may cause a fire or electric shock.
• Before opening the DU unit's cover, to prevent electric shocks or burns, be sure to disconnect the DU's power cord from the power supply.
• Do not modify the DU unit. It may cause a fire or an elec­tric shock.
• Do not use touch panel keys or switches for any life re­lated or important disaster prevention situations. Use separate hardware switches for such keys.
• Do not create touch panel switches that are used to either control or to ensure the safety of equipment and person­nel. Mechanical switches, such as an emergency stop
switch, a deadman (two-handed) start switch, etc., must be installed and operated via a separate control system.
PL-DU6900/PL-DU7900 User Manual2

Preface
• After the PL’s backlight burns out, unlike the PL’s
“Standby Mode”, the touch panel is still active. If the op­erator fails to notice that the backlight is burned out and touches the panel, a potentially dangerous machine miss­operation can occur.
If your PL's backlight suddenly turns OFF, use the followin g
steps to determine if the backlight is actually burned out.
1) If your PL is
not set to "Standby Mode" and the screen
has gone blank, your backlight is burned out.
2) Or, if your PL
is set to Standby Mode, but touching the screen does not cause the display to reappear, your backlight is burned out.
• Do not allow water, liquids, or metal particles to enter inside the DU's chassis, since they can cause either a malfunction or an electrical shock. If, however, either of these events occurs, disconnect the DU unit's power cord immediately and contact your local DUdistributor .
• Read and understand Chapter 4 “Installation and Wiring” thoroughly before selecting an installation location for the DU.
• Do not insert/remove an expansion board or an interface unit while the DU unit's power cord is connected to the power supply.
• To prevent a possible explosion, do not install the DU in areas containing flammable gases.
• The DU is not appropriate for use with aircraft control devices, aerospace equipment, central trunk data trans­mission (communication) devices, nuclear power control devices, or medical life support equipment, due to these devices’ inherent requirements of extremely high levels of safety and reliability.
• When using the DU with transportation vehicles (trains, cars and ships), disaster and crime prevention devices, various types of safety equipment, non life-support re­lated medical devices, etc. redundant and/or fail-safe system designs should be used to ensure the sufficient
degree of reliability and safety.

Preface
CAUTIONS
• When the surface or the frame of the display becomes dirty, soak a soft cloth in water with a neutral detergent, wring the cloth tightly, and wipe the display. Do not use paint thinner, organic solvents, or a strong acid com­pound to clean the unit.
• Avoid using or storing the DU in direct sunlight, or in ex­cessively dusty, dirty or hot environments.
• Do not use the DU in areas where large, sudden temperature changes can occur thereby causing condensation to form inside the unit. This can cause the unit to malfunction.
• Avoid restricting the DU's naturally occuring ventilation, or storing or using the DU in an environment that is too hot.
• Do not store or use the DU where chemicals and acids evaporate, or where chemicals and acids are dispersed into the air.
• Do not hold the DU's display stand to carry the DU. This stand is not meant for carrying the DU and if it breaks, the unit may fall and injure you.
LCD Handling Caution
The GP's LCD contains a strong irritant. If the panel is
ever cracked and the LCD's liquid contacts your skin, be sure to wash it with running water for at least 15 minutes. If any of this liquid should enter your eye, be sure to flush your eye with running water for more than 15 minutes and see a doctor as soon as possible.

Preface

General Safety Precautions

LCD Usage and Handling
• The brightness of the LCD screen will depend on the screen's current display
and the LCD's contrast adjustment. Any brightness variations that result are normal for LCD displays.
• There are minute grid-points (Dark or Light points) on the LCD surface. These
points are not defects and are a part of the DU panel’s design.
• The displayed color will look different when viewed from an angle outside the specified view angle. This is also normal.
• When installing this unit, be sure that the screen is viewable from within the designated direction, otherwise the view angle will be effected.
• Displaying a single screen image for long periods of time can cause an afterim­age to remain on the screen. To correct this, turn the unit OFF for 5 to 10 minutes, then ON again. This phenomenon is a common attribute of the LCDs, and is not a defect. To prevent this effect, you can:
1) Use the Display OFF feature; if the same image is to be displayed for a long
period of time.
2) Change the screen display periodically to prevent the displaying of a single
image for a long period of time.
(For further information about LCD usage and handling, contact your local DU
distributor.)

Prior to Using the DU

After connecting the DU to the PL and setting up the PL's OS, you will need to input the DU's screen settings and perform touch panel calibration.

This can occur in areas where either vaporized oils are present, or where low viscosity cutting oils are allowed to adhere to the unit for long periods of time. If the DU’s front face protection sheet becomes peeled off, these conditions can lead to the ingress of oil into the DU and separate protection measures are suggested. Also, if non­approved oils are present, it may cause deformation or corrosion of the front panel’s plastic cover. Therefore, prior to installing the DU be sure to confirm the type of conditions that will be present in the DU’s operating environment.
If the installation gasket is used for a long period of time, or if the unit and its gasket are r e­moved from the panel, the original level of the pr otection cannot be guaranteed. To maintain the original protection level, you need to r eplace the installation gasket regularly.
*2 Be sure to use your country's applicable standard.

• To improve noise immunity, it is recom-
mended to attach a ferrite core to the power cord.
• Isolate the main circuit (high voltage,
large current) line, I/O signal lines, and power cord, and do not bind or group them together.
• To prevent damage from lightning,
connect a lightning surge absorber.

• Set up a dedicated ground when using the rear panel’s FG terminal.
• If a dedicated ground is not possible, use a shared ground, as shown in figure (b).
• The grounding point must be as close to the DU as possible, and the grounding wires must be as short as possible. If the wires must be long, use thick, insulated wires and run them through conduits.

4.3.5 Cautions When Connecting I/O Signal Lines

• I/O signal lines must be wired separately from the power cord.
• If the power code needs to be wired together with the cord (I/O) signal
lines for any reason, use shielded cables and ground one end of the shield to the DU’s FG terminal.
• To improve noise immunity, attaching a ferrite core to the power cord is recommended.
*1 Use a grounding resistance of less than 100 Ω and a 2mm2 or thicker wire, or your country’s
applicable standard. For details, contact your local DU distributor.
