Preface

Essential Safety Precautions

This manual includes procedures that must be followed to operate the GP correctly and
safely. Be sure to read this manual and any related materials thoroughly to understand
the correct operation and functions of the GP unit.
Safety Symbols
Throughout this manual, the following icons identify GP operation procedures that
require special attention. These icons provide essential safety information for the follow-
ing levels of danger:
System Design
Do NOT make switches using the switches on the touch
•
panels, which may cause operator injury and machine dam-
age. To prevent major accidents caused by an output re-
maining either ON or OFF, set up circuits (such as limiters)
that will monitor vital output signals. To prevent accidents
caused by incorrect output or malfunction, design switches
used by separate devices to perform important operations.
• Do NOT use GP touch panel switches to perform safety-
related or important accident-prevention operations. These
operations should be performed by separate hardware
switches to prevent operator injury and machine damage.
• To prevent any possibility of bodily injury or material dam-
age, design your system so that equipment will not mal-
function due to a communication fault between the GP unit
and its host controller.
