[DESIGN PRECAUTIONS]
Some failures of the GOT, communication unit or cable may keep the outputs on or off.
Some failures of a touch panel may cause malfunction of the input objects such as a touch switch.
An external monitoring circuit should be provided to check for output signals which may lead to a
serious accident.Not doing so can cause an accident due to false output or malfunction.
Do not use the GOT as the warning device that may cause a serious accident.
An independent and redundant hardware or mechanical interlock is required to configure the device
that displays and outputs serious warning.
Failure to observe this instruction may result in an accident due to incorrect output or malfunction.
The GOT backlight failure disables the operation on the touch switch(s).
When the GOT backlight has a failure, the POWER LED blinks (orange/blue) and the display section
dims. In such a case, the input by the touch switch(s) is disabled.
The display section of the GOT is an analog-resistive type touch panel.

display section. Doing so may cause an accident due to incorrect output or malfunction.
[GT23]
If you touch the display section simultaneously in two 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 two 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
