Power supply
Twist the wires of the power supply.
-
The unit has sufficient noise immunity against the noise generated on the power line. However, it is
-
recommended to take measures for reducing noise such as using an isolating transformer before
supplying the power. And it is recommended to take measures such as installing a ferrite core.
Allocate an independent wiring for each power supplying line, PLC etc and operating device.
-
If using a power supply without a protective circuit, power should be supplied through a protective
-
element such as fuse. Directly applying an abnormal voltage to the unit may cause the damage to the
internal circuit.
Touch switches
Always operate the touch switch with fingers. As the touch switch may be damaged due to the
-
excessive load or shock (caused when being operated with any tools), the touch switch should be
operated within the specified control force. Also, if the touch switch is pressed like kneading, the
electrode may be worn out exceptionally, and cause the malfunction. Operate with a single touch of
the switch.
The touch position may shift due to aging variation. If the touch position has shifted, please adjust it.
-
LCD panel
Do not drop or have a strong impact on the programmable display unit as glass is used for the LCD
-
panel.
The liquid in the LCD panel is a hazardous substance. If the LCD panel is broken, do not put the leaked
-
crystalline liquid into your mouth. Should it get into your mouth, immediately gargle, and consult a
doctor. If it adheres to your skin or clothes, wash it away with soap.
On the LCD panel, bright spots ( points always lit) or black spots (points always unlit) may appear, or
-
the uneven brightness, flickers or crosstalk (appearance of unintended shades in the area no graphic
or part is arranged) may occur depending on the operating conditions. Note that these phenomena are
resulted from the basic characteristics of LCD panel not defects or failures of the product.
Battery
Do not leave the battery in the unit when it is not used. There is a possibility of leak if it is left being
discharged.
Scratch protection sheet
A sheet is affixed to the touch panel to protect it from scratches when shipping. Please remove it before
using the GT.
