[DESIGN PRECAUTIONS]

WARNING

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.

• GT27,GT25,GT23

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.

•GT21

When the GOT backlight has a failure, the display section dims. In such a case, the input by the

touch switches is disabled.

Even if the display section dims on the liquid crystal of the GOT, the input by the touch switch(s) may

remain enabled. This may cause a malfunction 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.

The GOT backlight failure can be checked with a system signal of the GOT.

The display section of the GOT is an analog-resistive type touch panel.

When multiple points of the display section are touched simultaneously, an accident may occur due

to incorrect output or malfunction.

•GT27

Do not touch three points or more simultaneously on the display section. Doing so may cause an

accident due to an incorrect output or malfunction.

• GT25,GT23,GT21

Do not touch two points or more simultaneously on the display section. Doing so may cause a

touch switch near the touched points to operate unexpectedly, or may cause an accident due to

an 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 turn on the unit again after shutting off the power as soon as

possible.

Not doing so can cause an accident due to false output or malfunction.

If a communication fault (including cable disconnection) occurs during monitoring on the GOT,

communication between the GOT and PLC CPU is suspended and the GOT becomes inoperative.

For bus connection (GT27,GT25 Only) : The CPU becomes faulty and the GOT becomes

inoperative.

For other than bus connection : The GOT becomes inoperative.

A system where the GOT is used should be configured to perform any significant operation to the

system by using the switches of a device other than the GOT on the assumption that a GOT

communication fault will occur.

Not doing so can cause an accident due to false output or malfunction.
