[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 detects its backlight failure, the GOT disables the input operation on the touch
switch(s). Thus, operators cannot operate the GOT with touches. The GOT backlight failure can be
checked with a system signal of the GOT.
●
Even when the display section has dimmed due to a failure of the liquid crystal section or the backlight
on the GOT, the input operation of the touch switches may still be enabled. This may cause an
incorrect operation of the touch switches. 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.
WARNING
Indicates that incorrect handling may cause hazardous
conditions, resulting in death or severe injury.
CAUTION
Indicates that incorrect handling may cause hazardous
conditions, resulting in medium or slight personal injury or
physical damage.
