Essential Safety Precautions
This manual includes procedures that must be followed to operate the ST correctly and safely. Be sure to read this manual
and any related materials thoroughly to understand the correct operation and functions of this unit.
Safety Icons
Throughout this manual the following icons are provided next to ST operation procedures requiring special attention, and
provide essential safety information. These icons indicate the following levels of danger:
warning: Indicates situations where severe bodily injury, death or major equipment damage can occur.
System Design
Indicates situations where severe bodily injury, death or major equipment dam-
age can occur.
Indicates situations where slight bodily injury or machine damage can occur.
Do not create ST touch panel switches that could possibly endanger the safety of equipment and personnel. Damage
to the ST, its I/O unit(s), cable(s), and other related equipment can cause an output signal to remain continuously ON
or OFF and possibly cause a major accident. Therefore, design all monitoring circuits using limit switches, etc. to
detect incorrect device movement. To prevent accidents related to incorrect signal output or operation, design all
switches used to control vital machine operations so they are operated via a separate control system.
Please design your system so that equipment will not malfunction due to a communication fault between the ST and
its host controller. This is to prevent any possibility of bodily injury or material damage.
Do not use the ST unit as a warning device for critical alarms that can cause serious operator injury, machine damage
or production stoppage. Critical alarm indicators and their control/activator units must be designed using stand-alone
hardware and/or mechanical interlocks.
The ST 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.
Do not create switches used to control machine safety operations, such as an emergency stop switch, or a ST touch
screen icon. Be sure to install these switches as separate hardware switches, otherwise severe bodily injury or equip-
ment damage can occur.

Touch Panel
Wiring
When using the ST with : transportation vehicles (trains, cars and ships), disaster and crime prevention devices, var-
ious 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.
After the ST's backlight burns out, unlike the ST’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 error
can occur.
If your ST's backlight suddenly turns OFF, use the following steps to determine if the backlight is actually burned
out.
1) If your ST is not set to "Standby Mode" and the screen has gone blank, your backlight is burned out.
2) Or, if your ST is set to Standby Mode, but touching the screen does not cause the display to reappear, your back-
light is burned out.
To prevent electrical shock or equipment damage, unplug the ST unit's power cord from the power supply prior to
installing or wiring the ST.
Be sure to replace the ST's plastic terminal block cover after wiring is completed, since operating the ST without the
cover may lead to an electric shock.
Do not use power beyond the ST's specified voltage range. Doing so may cause a fire or an electric shock.

Battery Replacement
Installation/Maintenance
Installation/Maintenance
Wiring
The ST uses a lithium battery for backing up its internal clock data. If the battery is incorrectly replaced, the battery
may explode. To prevent this, please do not replace the battery yourself. When the battery needs to be replaced,
please contact your local ST distributor.
High voltage runs through the ST. Except for replacing the backlight, never take apart the ST, otherwise an electrical
shock can occur.
Do not modify the ST unit. Doing so may cause a fire or an electric shock.
Do not use the ST in an environment where flammable gasses are present, since operating the ST may cause an
explosion.
Be sure to securely connect all cable connectors to the ST. A loose connection may cause incorrect input or output.
Ground the ST's FG line separately from other units’ FG lines. Putting these FG lines too close may cause an electric
shock or unit malfunction. Be sure to use a grounding resistance of 100W or less and a 2mm2or thicker wire, or your
country's applicable standard.

Display Device
Unit Disposal
Be sure the ST's rated voltage is within the designated range, and that the power terminal lines are correctly attached.
If the voltage supplied differs from the rated voltage, or incorrect wiring or grounding is performed, it may cause a
fire or unit malfunction.
Use only the designated torque to tighten the ST's terminal block screws. If these screws are not tightened firmly, it
may cause a short-circuit, fire, or ST malfunction.
Be careful that metal filings and wiring debris do not fall inside the ST, since they can cause a fire, ST malfunction,
or incorrect unit operation.
The liquid crystal panel contains a powerful irritant and if for any reason the panel is damaged and this liquid con-
tacts any part of your body, be sure to wash that area with running water for 15 minutes. If any of this liquid enters
your eye, flush your eye for 15 minutes with running water and contact a physician.
When this unit is disposed of, it should be done so according to your country's regulations for similar types of indus-
trial waste.
This mark is applicable only in Taiwan.

General Safety Precautions
About the Operation Environment
• Do not strike the touch panel with a hard or pointed object, or press on the touch panel with too much force, since it
may damage the touch panel or the display.
• Do not install the ST where the ambient temperature can exceed the allowed range. Doing so may cause the ST to mal-
function or shorten its operation life.
• Do not restrict or limit the ST’s naturally occurring rear-face ventilation, or store or use the ST in an environment that
is too hot.
• Do not use this unit in areas where large, sudden temperature changes can occur. These changes can cause condensa-
tion to form inside the unit., possibly causing the unit to malfunction.
• Do not allow water, liquids, metal or charged particles to enter inside the ST's case, since they can cause either a ST
malfunction or an electrical shock.
• Do not use or store the ST in direct sunlight, or in excessively dusty or dirty environments.
• Do not store or use the unit where strong jolting or excessive vibration can occur.
• Do not store or use the ST where chemicals (such as organic solvents, etc.) and acids can evaporate, or where chemi-
cals and acids are present in the air.
Corrosive chemicals:Acids, alkalines, liquids containing salt
Flammable chemicalsOrganic Solvents
• Do not use paint thinner or organic solvents to clean the ST, since they can cause either discoloration or a ST malfunc-
tion.
• Do not store or operate the LCD display in areas receiving direct sunlight, since the sun's UV rays may cause the LCD
display quality to deteriorate.
• Storing this unit in areas at a temperature lower than is recommended in this manual specifications may cause the LCD
display liquid to congeal, which may damage the panel. Conversely, if the storage area temperature becomes higher
than the allowed level, the LCD liquid will become isotropic, causing irreversible damage to the LCD. Therefore, be
sure to store the panel only in areas where temperatures are within those specified in this manual.
• Do not connect or disconnect the communication cable between the ST and the host during power-ups.
About the Screen Data
• Due to the possibility of unexpected accidents, be sure to back up the ST’s
screen data regularly.

About the ST's Display Panel
• The ST's currently displayed data, its voltage*1 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 ST's design and not a
defect.
• Extended shadows, or "Crosstalk" may appear on the sides of screen images. 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 effect:
• Use the ST's "Stand-by Mode", which automatically turns the screen OFF when there is no input for a
specified period of time.
• Write "FFFh" to the System Data Area's “Screen Display Off” address*2 to turn the screen display OFF when the
following actions are not performed for the user's designated period of time.
• Change Screen
• Touch Screen
• Alarm Display
• Do not display any single screen for a long period of time. Try to periodically change the screen display.
*1 If the ST's voltage is at the very low end of its allowable range, it may effect the intensity of contouring.
SEE 6.3.1 System Setup (Page 6-4)
