Essential Safety Precautions
All safety-related procedures stated in this document must be followed to operate the PS-A correctly and safely. Be sure
to read this and any related documents thoroughly to understand the correct operation and functions of the PS-A unit.
Safety Icons
Throughout this manual, these icons provide essential safety information for PS-A operation procedures requiring special
attention. These icons indicate the following levels of danger:
System Design
Indicates situations where severe bodily injury, death or major equipment damage
can occur.
Indicates situations where slight bodily injury or minor equipment damage can
occur.
Indicates actions or procedures that should NOT be performed.
Indicates actions or procedures that MUST be performed to ensure correct unit
operation.
Do not create PS-A touch panel switches that could possibly endanger the safety of personnel or
equipment.
A malfunction of the PS-A 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 PS-A.
Do not create PS-A 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 PS-A 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 PS-A 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.

Handling
Wiring
Maintenance
Do not use the PS-A 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 design your system so that a communication fault between the PS-A and its host controller will
not cause equipment to malfunction. This is to prevent any possibility of bodily injury or equipment
damage.
After the PS-A unit’s backlight burns out the touch panel is still active, unlike the PS-A 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 PS-A unit touch panel switches
that may cause injury and/or equipment damage. If your PS-A unit’s backlight suddenly turns OFF, use
the following steps to determine if the backlight is actually burned out.
1) If the PS-A unit’s “Backlight Control” is not set and the screen has gone blank, your backlight is burned
out.
2) If the PS-A 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.
Do not disassemble or modify the PS-A unit. Doing so may cause a fire or an electric shock.
Do not operate the PS-A in an environment where flammable gases are present, since it may cause an
explosion.
To prevent electrical shock or equipment damage, unplug the PS-A unit’s power cord from the power
supply prior to installing or wiring the PS-A.
Do not use the voltage not specified in the manual. Doing so may cause a fire or an electric shock.
Do not connect or disconnect Host and PS-A unit communication cables while the PS-A is turned ON.
The PS-A 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 replacement product.
SEE “4.6 Replacing the Internal Battery” (page 4-10)

Installation
Wiring
Maintenance
Unit Disposal
General Safety Precautions
Be sure all cable connectors are securely attached to the PS-A unit. A loose connection may cause
incorrect input or output signals.
Be sure to ground the PS-A unit’s FG wire separately from other equipment FG lines. Also, be sure to use
a grounding resistance of 100Ωor less and a 2mm2or 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 PS-A 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 PS-A unit. They can cause a fire,
malfunction or incorrect unit operation.
Do not reset or turn the PS-A OFF, or insert or remove the CF Card while the PS-A unit’s CF Card or hard
disk is being accessed. Otherwise, CF Card and the hard disk internal data may be damaged or lost.
When the product is disposed of, it should be disposed of in a manner appropriate to, and in accordance
with, the user country's industrial machinery disposal/recycling standards.
Do not press on the PS-A 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 PS-A where the ambient temperature exceeds the specified range. Doing so may cause
a unit malfunction.
To prevent abnormally high temperatures from occurring inside the PS-A, do not restrict or block the PS-A
unit’s rear-face ventilation slots.
Do not operate the PS-A in areas where large, sudden temperature changes can occur. These changes
can cause condensation to form inside the PS-A, possibly causing it to malfunction.
Do not allow water, liquids or metal fragments to enter inside the PS-A unit’s case, since they can cause
either a malfunction or an electric shock. The allowable pollution degree is 2.

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, immedi-
ately 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 PS-A unit’s LCD screen may flicker or show unevenness in the brightness of certain images or at some contrast
settings. This is an LCD characteristics and not a product defect.
• There’s an individual difference in brightness and tone of LCD screen. Please be aware of this difference before using
the lined-up plural units.
• Some of PS-A unit's LCD screens may contain black and white colored pixels. This is an LCD characteristic and not a
product defect.
• Extended shadows, or “Crosstalk” may appear on the sides of screen images. This is an LCD characteristic and not a
product defect.
• The color displayed on the PS-A unit’s LCD screen may appear different when seen from outside the specified view-
ing angle. This is an LCD characteristic and not a product defect.
• When the same image is displayed on the PS-A unit’s screen for a long period, an afterimage may appear when the
image is changed. This is an LCD characteristic and not a product defect.
Do not operate or store the PS-A in locations where it can be exposed to direct sunlight, high
temperatures, excessive dust, moisture or vibration.
Do not operate or store the PS-A 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 PS-A unit’s surface. Instead, use
a soft cloth moistened with a diluted neutral detergent.
Do not use or store the PS-A in areas with direct sunlight, since the sun’s ultraviolet rays may cause the
LCD’s quality to deteriorate.
Do not store the PS-A in an area where the temperature is lower than that recommended in the PS-A
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 PS-A in areas where
temperatures are within the PS-A unit’s specifications.
After turning OFF the PS-A unit, be sure to wait at least 5 seconds before turning it ON again. The PS-A
unit may not operate correctly if it is restarted too quickly.
Due to the possibility of unexpected accidents, be sure to back up the PS-A unit's data regularly.
