zSAFETY PRECAUTIONS z
(Read these precautions before using.)
Before using this product, please read this manual and the relevant manuals
introduced in this manual carefully and pay full attention to safety to handle the
product correctly.
The instructions given in this manual are concerned with this product. For the
safety instructions of the programmable controller system, please read the CPU
module user's manual.
In this manual, the safety instructions are ranked as "WARNING" and
"CAUTION".
DANGER
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.
Note that the CAUTION level may lead to a serious consequence according
to the circumstances.
Always follow the instructions of both levels because they are important to
personal safety.
Please save this manual to make it accessible when required and always
forward it to the end user.
[DESIGN PRECAUTIONS]
DANGER
zSome failures of the GOT main unit, communication module, communication
board or cable may keep the outputs on or off.
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.
zIf 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: The CPU becomes faulty and the GOT 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.

[DESIGN PRECAUTIONS]
DANGER
zDo 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.
zIncorrect 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 display section turns black and
causes the monitor screen to appear blank, while the input of the touch
switch(s) still 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 monitor screen disappears even when the screensaver is not set.
•The monitor screen will not come back on by touching the display section,
even if the screensaver is set.
CAUTION
zDo 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.
[MOUNTING PRECAUTIONS]
DANGER
zBefore installing or removing the GOT main unit to or from an enclosure,
always switch off the GOT power externally in all phases.
Not doing so can cause a module failure or malfunction.
zBefore loading or unloading the communication board, communication
module, External I/O module or memory board to or from the GOT, always
switch off the GOT power externally in all phases.
Not doing so can cause a module failure or malfunction.

[MOUNTING PRECAUTIONS]
CAUTION
zThe GOT should be used in the environment given in the general
specifications of this user's manual.
Not doing so can cause an electric shock, fire, malfunction or product
damage or deterioration.
zWhen mounting the GOT main unit to an enclosure, tighten the mounting
screws in the specified torque range.
Undertightening can cause a drop, short circuit or malfunction.
Overtightening can cause a drop, short circuit or malfunction due to the
damage of the screws or module.
zWhen loading the communication board, communication module or
External I/O module to the GOT main unit, fit it to the connection interface
of the GOT and tighten the mounting screws in the specified torque range.
Undertightening can cause a drop, failure or malfunction.
Overtightening can cause a drop, failure or malfunction due to the damage
of the screws or module.
zWhen loading the memory board into the GOT main unit, load it into its
corresponding GOT slot and tighten the mounting screws in the specified
torque range.
Undertightening can cause a malfunction due to a contact fault.
Overtightening can cause a malfunction due to the damage of the screws
or module.
zWhen loading the PC card into the GOT main unit, insert and push it into its
corresponding GOT slot until the PC card eject button comes up.
Not doing so can cause a malfunction due to a contact fault.
zBefore loading or unloading the PC card to or from the GOT, set the
memory card access switch to the OFF position.
Not doing so can cause the PC card data to be corrupted.
[WIRING PRECAUTIONS]
DANGER
zBefore starting wiring, always switch off the GOT power externally in all
phases.
Not doing so may cause an electric shock, product damage or malfunction.

[WIRING PRECAUTIONS]
CAUTION
zPlease make sure to ground FG terminal, LG terminal, and protective
ground terminal of the GOT power supply unit by applying Class D
Grounding (Class 3 Grounding Method) or higher which is used exclusively
for the GOT.
Not doing so may cause an electric shock or malfunction.
zCorrectly wire the power supply module on the GOT after confirming the
rated voltage and terminal arrangement of the product.
Not doing so can cause a fire or failure.
zTighten the terminal screws of the GOT power supply section in the
specified torque range.
Undertightening can cause a short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to the damage
of the screws or module.
zExercise care to avoid foreign matter such as chips and wire offcuts
entering the module.
Not doing so can cause a fire, failure or malfunction.
zPlug the bus connection cable by inserting it into the connector of the
connected module until it "clicks".
After plugging, check that it has been inserted snugly.
Not doing so can cause a malfunction due to a contact fault.
zPlug the communication cable into the connector of the connected module
and tighten the mounting and terminal screws in the specified torque range.
Undertightening can cause a short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to the damage
of the screws or module.
[TEST OPERATION PRECAUTIONS]
DANGER
zBefore performing test operation (bit device on/off, word device's present
value changing, timer/counter's set value and present value changing,
buffer memory's present value changing) for a user-created monitor screen,
system monitoring, special module monitoring or ladder monitoring, read
the manual carefully to fully understand how to operate the equipment.
During test operation, never change the data of the devices which are used
to perform significant operation for the system.
False output or malfunction can cause an accidet.
