FP-790T User Manual2

• To avoid the possiblity of an electric shock, be sure to connect the power
cord to the FP before connecting it to the main power supply.

• A fire or electrical shock may occur if voltages used with the FP are beyond
the specified range. Be sure to use only the specified voltage.

• Before opening the FP's protective cover, be sure to turn the units power
OFF. This is because the FP's internal parts carry high voltages.

• To avoid fires or electrical hazards, do not modify the FP in any way.

• 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.

• Do not create touch panel switches which could possibly endanger the safety
of humans and equipment. This is due to the possibility of a malfunction in
the FP or its cable(s), causing the output of a signal that could result in a
major accident. All of a system’s major, safety-related switches should be
designed to be operated separately from the FP.

This section describes the safety precautions necessary for the correct use of the FP.
Please keep this manual close at hand and refer to it when necessary.

Safety Icons

The following symbols are used throughout this manual to ensure the safe use of the

FP-790T User Manual 3

WARNINGS

• After the FP's backlight burns out, unlike the FP'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 operation
mistake can occur.

If your FP's backlight suddenly turns OFF, use the following steps to
determine if the backlight is actually burned out.

1)If your FP is not set to "Standby Mode" and the screen has gone blank,
your backlight is burned out.

2)Or , if your FP is set to Standby Mode, but touching the screen does not
cause the display to reappear, your backlight is burned out.

• If metal particles, water or other types of liquids contact any of the FP's
internal parts, immediately turn the units power OFF, unplug the power cord,
and contact either your FP distributor or the Digital Electronics Corporation.

• Read and understand Chapter 3 "Installation and Wiring" thoroughly in order
to select an appropriate installation location for the FP.

• Before either plugging in or unplugging a board or interface connector, be
sure to turn the FP's power OFF.

• To prevent a possible explosion, do not install the FP in areas containing
flammable gases.

• The FP 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 FP 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 failsafe
system designs should be used to ensure the proper degree of reliability
and safety.

FP-790T User Manual4

 About the FP's Display Panel

• The FP's currently displayed data, its voltage and brightness setting each affect the intensity

of Contouring. (i.e, when some parts of the screen are brighter than others, creating a
wavelike pattern)

• There are minute grid-points (dark and light) on the Display Panel's surface. This is part of

the FP's design and not a defect.

• Shadows may appear at the top of the LCD. This is normal for an LCD display .

• Sometimes the display area may look as if the display colors have changed. This is a

common attribute of LCD's and is not a defect.

• Displaying a single image for long periods can cause an afterimage to remain when the

display is changed to another screen. To prevent this, periodically turn the FP OFF and
then ON again to remove this afterimage.

• Do not push on the FP’s screen too strongly , with either your finger or with a
hard object. Excessive pressure can scratch, crack or damage the screen.

• Do not use a pointed object, such as a mechanical pencil or screw-driver, to
press any of the touch panel’s switches, since they can damage the display.

• If the screen becomes dirty or smudged, moisten a soft cloth with diluted
neutral detergent, wring the cloth well, and wipe the display. Do not use thin­ner or organic solvents.

• Avoid exposing the FP to, or operating the FP in direct sunlight, high tem­peratures and humidity , and in areas where excessive dust and vibration will
occur.

• Avoid using the FP in areas where sudden, extreme changes in temperature
can occur. This may cause con-densation to form inside the unit, possibly
leading to an accident.

• To prevent the FP from overheating, be sure its air circulation vents are clear
and clean, and keep the unit’s operation area well-ventilated.

• Avoid operating or storing the FP near chemicals, or where chemicals can
come into contact with the unit.

2-1-2 Structual Specifications

*1 The front face of the FP unit, installed in a solid panel, has been tested using conditions

equivalent to the standard shown in the specification. Even though the FP unit’s level of
resistance is equivalent to the standard, oils that should have no effect on the FP 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 FP’s front face protection sheet becomes peeled off, these conditions can lead to the
ingress of oil into the FP and separate protection measures are suggested. Also, if non­approved oils ar e present, it may cause deformation or corrosion of the fr ont panel’s plastic
cover. Therefore, prior to installing the FP be sure to confirm the type of conditions that
will be present in the FP’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, you need to replace the installation gasket regularly.

Signal Names

Signal names used for the FP's serial interface are designed to match the
pin order used on most PC serial interfaces, so that a straight cable can be
used to connect the two. Therefore, connect each pin's signal to the same
signal name on the PC connector.

3. Setup of Operation Mode and Positioning of Display

• Before mounting the FP into a cabinet or panel, check that the
Installation Gasket is attached to the unit.

• A gasket which has been used for a long period of time may
have scratches or dirt on it, and could have lost much of its dust
and drip resistance. Be sure to change the gasket periodically,
or when scratches or dirt become visible.

• The gasket must be inserted correctly into the groove for the
FP’s moisture resistance to be equivalent to IP65f.

• The upper surface of the gasket should protrude approximately
2mm out from the groove. Be sure to check that the gasket is
correctly inserted before installing the FP into a panel.

3-1-1 Installation Procedures

Install the FP according to the following procedures.

• The gasket is flexible, but not elastic, and may tear if stretched
too far. Do not stretch the gasket around the ribs, only push.

• Be sure the gasket’s seam is not inserted into any of the unit’s
corners, only in the straight sections of the groove. Inserting it
into a corner may lead to its eventually tearing.

3-2-5 FP Input/Output Signal Line Cautions

Input and output signal lines must be separated from power cables.
If this is not possible, use a shielded cable and connect the shield to the FP

chassis.

3-2-4 FP Grounding Cautions

other
equipment

(a) Exclusive grounding (BEST)

(b) Common grounding (OK)

If exclusive grounding is not possi­ble, use a common grounding point.

The grounding wire should have a
cross section larger than 2mm2. Make
the connection point as close to the
FP as possible, and make the wire as
short as possible. When using a long
grounding wire, use a thicker wire
placed in a duct.

If the FP does not function properly
when grounded this way, disconnect
the ground wire from the FP's FG ter­minal.

Connect the FP's FG terminal to an
exclusive ground. [Grounding
resistance of under 100Ω.]

panel data to the host.

RS-232C connection (When SW1-1 is OFF)

Coordinate output data sent from the FP to the host is not exactly equal to the
coordinates used on the display device. Therefore, an I/F program is necessary
to convert the coordinates on the touch panel into those used on the display
device. It is also necessary to calibrate individual panel differences, depending
on the touch panel used.

The mouse emulation software listed below can automatically convert the
coordinates with simple initial settings.

A separate conversion program is required when using a different OS. To create
a conversion program for a different OS, please observe the following

A maximum of 87 points per second.

(4) Cable Connection

Connect the RS-232C connector provided at the rear of the FP to the host’s
serial interface through the optional SIO cable.

Chapter 1 Introduction

Connect the host (PLC) data cable to the FP's rear-mounted RS-232C connector.
(Digital's optional SIO cable is recommended)

The PL's touch panel provides a resolution of “1024” (10 bit). However,
the resolution of the actual output data is only 20 to 990 (approx.).
Therefore, all the coordinates of the pixels on the horizontal axis cannot
be detected. According to this calculation, the FP's output data includes
coordinates that cannot be displayed, since the touch panel is larger
than the display device.

Maintenance

FP-790T User Manual 6-3

Replace the backlight according to the procedure below . (The following explanation
assumes that the FP has already been removed from the panel)

6-3 Changing the Backlight

• Be sure the FP's power cord has been disconnected prior to
changing the backlight. When the FP's power cord is connected
and the FP is ON, high voltage runs through the wires in the
backlight area. Do not touch them!

• When the FP's power cord has just been disconnected, the back­light area is still very hot! Be sure to wear gloves to prevent be­ing burned.

• The backlight is very fragile. Do not touch the glass tube directly
or try to remove its power cord. If the glass tube breaks you may
be injured.

Warning

• During replacement, be sure to protect the front surface of the FP’s
display so that it is not scratched or damaged.

• The FP has both an upper and a lower backlight bulb. Be sure to
replace both at the same time.

• Since CFL is used for the backlights, they should be disposed of in
a manner appropriate to your local government’s laws or
regulations.
