[DESIGN PRECAUTIONS]
● Incorrect operation of the touch switch(s) may lead to a serious accident if the GOT backlight is gone
out.
When the GOT backlight goes out, the POWER LED flickers (green/orange) and the display section
turns black and causes the monitor screen to appear blank, while the input of the touch switch(s)
remains active.
This may confuse an operator in thinking that the GOT is in "screensaver" mode, who then tries to
release the GOT from this mode by touching the display section, which may cause a touch switch to
operate.
Note that the following occurs on the GOT when the backlight goes out.
• The POWER LED flickers (green/orange) and the monitor screen appears blank.
● The display section of the GT16 is an analog-resistive type touch panel.
If you touch the display section simultaneously in 2 points or more, the switch that is located around
the center of the touched point, if any, may operate.
Do not touch the display section in 2 points or more simultaneously.
Doing so may cause an accident due to incorrect output or malfunction.
● When programs or parameters of the controller (such as a PLC) that is monitored by the GOT are
changed, be sure to reset the GOT or shut off the power of the GOT at the same time.
Not doing so can cause an accident due to false output or malfunction.
● Do not bundle the control and communication cables with main-circuit, power or other wiring.
Run the above cables separately from such wiring and keep them a minimum of 100mm apart.
Not doing so noise can cause a malfunction.
● Do not press the GOT display section with a pointed material as a pen or driver.
Doing so can result in a damage or failure of the display section.
[MOUNTING PRECAUTIONS]
● Be sure to shut off all phases of the external power supply used by the system before mounting or
removing the GOT to/from the panel.
Not switching the power off in all phases can cause a unit failure or malfunction.
● Be sure to shut off all phases of the external power supply used by the system before mounting or
removing the communication unit, option function board or multi-color display board onto/from the
GOT.
Not doing so can cause the unit to fail or malfunction.
● Before mounting an optional function board or Multi-color display board, wear a static discharge wrist
strap to prevent the board from being damaged by static electricity.
