Pro-face PL-6931-T42 Specifications

Essential Safety Precautions
„ System Design
• Do not create PL-6930 series (hereafter referred to as the “PL”) touch panel switches that
could possibly endanger the safety of personnel or equipment. A malfunction of the PL unit,
its I/O unit(s), cable(s), or other related equipment can cause unexpected output signals,
leading to a serious accident. Be sure to design all important machine operation switches so
they are operated via a separate control system, and not via the PL.
• Do not create PL touch panel switches to control machine safety operations, such as an
emergency stop switch. Install these switches as separate hardware switches, otherwise
severe bodily injury or equipment damage can occur.
• Be sure to design your system so that a communication fault between the PL and its host
controller will not cause equipment to malfunction. This is to prevent any possibility of
bodily injury or equipment damage.
• Do not use the PL as a warning device for critical alarms that can cause serious operator
injury, machine damage or can halt system operation. Critical alarm indicators and their
control/activator units must be designed using stand-alone hardware and/or mechanical
interlocks.
• Do not use the PL 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.
• Be sure to use redundant and/or failsafe system designs to ensure adequate levels of system
reliability and safety when using the PL 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 PL unit’s backlight burns out the touch panel is still active, unlike the PL 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 PL unit touch panel switches that may cause injury and/or equipment damage.
If your PL unit’s backlight suddenly turns OFF, use the following steps to determine if the
backlight is actually burned out.
1) If the PL unit’s “Backlight Control” is not set and the screen has gone blank, your
backlight is burned out.
2) If the PL 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.
„ Handling
• Do not modify the PL unit. Doing so may cause a fire or an electric shock.
• Do not operate the PL 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 PL unit’s power cord from the power
supply before wiring the PL.
• Do not use voltage beyond the PL unit’s specified range. Doing so may cause a fire or an
electric shock.
1
„ Maintenance
• Do not connect or disconnect Host and PL unit communication cables while the PL is turned
ON.
• The PL 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
product.
„ Installation
• Be sure all cable connectors are securely attached to the PL unit. A loose connection may
cause incorrect input or output signals.
„ Wiring
• Be sure to ground the PL unit’s FG wire separately from other equipment FG lines. Also, be
sure to use a grounding resistance of 100Ω or less and a 2mm2 [0.0062inch2] or thicker wire,
or your country’s applicable standard. Otherwise, electric shock or malfunctions may result.
• Be sure to use only the designated torque to tighten the PL unit’s terminal block screws. If
these screws are not tightened firmly, it may cause a short-circuit, fire or incorrect unit
operation.
• Be sure that metal particles and wiring debris do not fall inside the PL unit. They can cause a
fire, malfunction or incorrect unit operation.
„ Maintenance
• Do not reset or turn the PL OFF, or insert or remove the CF Card while the PL unit’s CF
Card or hard disk is being accessed. Otherwise, CF Card and the hard disk internal data may
be damaged or lost.
„ Unit Disposal
• When the product is disposed of, it should be done so according to your country’s regulations
for similar types of industrial waste.
„ General Safety Precautions
• Do not press on the PL unit’s display with excessive force or with a hard object, since it can
damage the display. Also, do not press on the touch panel with a pointed object, such as the
tip of a mechanical pencil or a screwdriver, since doing so can damage the touch panel.
• Do not install the PL where the ambient temperature exceeds the specified range. Doing so
may cause a unit malfunction.
• To prevent abnormally high temperatures from occurring inside the PL, do not restrict or
block the PL unit’s rear-face ventilation slots.
• Do not allow water, liquids or metal fragments to enter inside the PL unit’s case, since they can
cause either a malfunction or an electric shock. (For use in Pollution Degree 2 environment.)
• Do not operate or store the PL in locations where it can be exposed to direct sunlight, high
temperatures, excessive dust, moisture or vibration.
• Do not operate the PL in areas where large, sudden temperature changes can occur. These
changes can cause condensation to form inside the PL, possibly causing it to malfunction.
• Do not operate or store the PL where chemicals evaporate, or where chemicals are present in
the air.
Corrosive chemicals: Acids, alkalines, liquids containing salt
Flammable chemicals: Organic Solvents
• Do not use paint thinner or organic solvents to remove dirt or oil from the PL unit’s surface.
Instead, use a soft cloth moistened with a diluted neutral detergent.
• Do not use or store the PL in areas with direct sunlight, since the sun’s ultraviolet rays may
cause the LCD’s quality to deteriorate.
2
• Do not store the PL in an area where the temperature is lower than that recommended in the
PL unit’s specifications. Doing so may cause the LCD display’s liquid to congeal, which can
damage the LCD. Also, if the storage area’s temperature becomes higher than the specified
level, the LCD’s liquid may become isotropic, causing irreversible damage to the LCD.
Therefore, only store the PL in areas where temperatures are within the PL unit’s
specifications.
• After turning OFF the PL, be sure to wait a few seconds before turning it ON again. The PL
may not operate correctly if it is restarted too quickly.
• Due to the possibility of unexpected accidents, be sure to back up the PL unit’s data
regularly.
„ LCD Panel Usage Precautions
• The LCD panel’s liquid contains an irritant. If the panel is damaged and any of this liquid
contacts your skin, immediately rinse the area with running water for at least 15 minutes. If
the liquid gets in your eyes, immediately rinse your eyes with running water for at least 15
minutes and consult a doctor.
• The PL unit’s LCD screen may show unevenness in the brightness of certain images or at
some contrast settings. This is an LCD characteristic and not a product defect.
• The PL unit’s LCD screen pixels may contain minute black and white-colored spots. This is
an LCD characteristic and not a product defect.
• The color displayed on the PL unit’s LCD screen may appear different when seen from
outside the specified viewing angle. This is an LCD characteristic and not a product defect.
• When the same image is displayed on the PL unit’s screen for a long period, an afterimage
may appear when the image is changed. If this happens, turn off the PL, wait 10 seconds and
then restart the unit. This is an LCD characteristic and not a product defect.
• To prevent an afterimage:
* Set the PL unit’s display OFF feature when you plan to display the same screen image for a
long period of time.
* Change the screen image periodically and try to not display the same image for a long period of
time.

• When using any of the PL ís optional devices, be sure to check that
deviceís specifications for any special conditions or cautions that may
apply to its use.
• Be aware that not only does the Hard Disk have a fixed lifetime, but that
accidents can always occur. Therefore, be sure to back up your Hard
Diskís data regularly, or prepare another Hard Disk unit that can be used
for backup.
• The Hard Disk lifetime given here may be reduced due to unforeseen
environmental factors, however, generally speaking, the disk should last
for 20,000 hours (of operation) or approximately 5 years, whichever
comes first at an operating temperature of 20oC and 333 hours of
operation per month. (HDD access frequency of 20% or less)
• Using the Hard Disk in an environment that is excessively hot and/or
humid will shorten the diskís usage lifetime. A wet bulb temperature of
29oC or less is recommended. This is equivalent to the following data.
Temperature
Humidity
35oC
no higher than 64%RH
o
40 C
no higher than 44%RH
• In order to extend the lifetime of the hard disk, Pro-face recommends you
set the Windows®2000 [Control panel]-[Power Management option][Turn off hard disks] selection / the Windows®XP [Control panel][Power and Maintenance]-[Power Options]-[Power Schemes]-[Turn off
hard disks] selection to turn the hard disk off when the unit is not being
operated. A setting of 5 minutes is recommended.

Grounding
*1 The front face of the PL unit, installed in a solid panel, has been tested using conditions
equivalent to the standards shown in the specification. Even though the PL unit’s level of
resistance is equivalent to these standards, oils that should have no effect on the PL can
possibly harm the unit. 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 PL’s front face protection sheet becomes peeled off, these conditions can
lead to the ingress of oil into the PL and separate protection measures are suggested.
Also, if non-approved oils are present, it may cause deformation or corrosion of the front
panel’s plastic cover. Therefore, prior to installing the PL be sure to confirm the type of
conditions that will be present in the PL’s operating environment.
If the installation gasket is used for a long period of time, or if the unit and its gasket are
removed from the panel, the original level of the protection cannot be guaranteed. To
maintain the original protection level, be sure to replace the installation gasket regularly.

the plug with two(2) minus screws.
• Confirm that all wires are connected correctly.
• The torque required to tighten these screws is 0.5N•m to 0.6N•m.
• To prevent the possibility of a terminal short, use a pin terminal that has
an insulating sleeve.
• The temperature rating of field installed conductors: 75°C or less.
2
Power Supply Cautions
• When supplying power to the PL unit, please separate the input/output and operation unit
lines.
• To increase the noise resistance quality of the power cord, simply twist each power wire
before attaching the Ring Terminal.
• The power cord must not be bundled or positioned close to main circuit lines (high voltage,
high current), or input/output signal lines.
• To avoid excess noise, make the power cord as short as possible.
• If the supplied voltage exceeds the PL unit’s range, connect a constant voltage transformer.
• For between the line and ground, select a power supply that is low in noise. If there is an
excess amount of noise, connect a noise reducing transformer.
• Use constant voltage and insulating transformers with capacities
exceeding 200VA.
17
• Connect a lightening surge absorber, as shown in the diagram, to deal with power surges.
• Be sure to ground the surge absorber (E1) separately from the PL unit
(E2).
• Select a surge absorber that has a maximum circuit voltage greater than
that of the peak voltage of the power supply.

Grounding Cautions
• Be sure to create an exclusive ground for the power cord’s FG terminal. Check that the
grounding resistance is less than 100 Ω.
• Inside the PL unit, the SG (Signal Ground) and FG (Frame Ground) terminals are connected.
When connecting an external device to the PL using the SG terminal, be sure to check that
no short-circuit loop is created when you setup the system.
• The grounding wire should have a cross sectional area greater than 2mm2 [0.0062inch2].
Create the connection point as close to the PL unit as possible, and make the wire as short, as
possible. When using a long grounding wire, replace the thin wire with a thicker wire, and
place it in a duct.

Input/Output Signal Line Cautions
• Input and output signal lines must be separated from the power control cables for operating
circuits.
• If this is not possible, use a shielded cable and connect the shield to the PL unit’s frame.
• To improve noise immunity, it is recommended to attach a ferrite core to the power cord.
