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.
