[DESIGN PRECAUTIONS]
WARNING
● Some failures of the GOT 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. Not doing so can cause an accident due to false output or malfunction.
● When the GOT backlight has a failure, the GOT status will be as follows.
Failure to observe this instruction may result in an accident due to incorrect output or malfunction.
[GS25]
The POWER LED blinks (orange/blue), the display section dims, and inputs by a touch switch are
disabled.
[GS21]
The POWER LED blinks (orange/blue), and the display section dims. However, inputs by a touch
switch are still available.
The GOT backlight failure can be checked with a system signal of the GOT.
Even if the display section dims, inputs by a touch switch may still be available. This may cause an
unintended operation of the touch switch.
For example, if an operator assumes that the display section has dimmed because of the screen save
function and touches the display section to cancel the screen save, a touch switch may be activated.
Indicates that incorrect handling may cause hazardous
conditions, resulting in death or severe injury.
Indicates that incorrect handling may cause hazardous

physical damage.
