Safety Precaution

(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 precautions given in this manual are concerned with this product.
In this manual, the safety precautions are ranked as "DANGER" and "CAUTION".

Depending on circumstances, procedures indicated by "CAUTION" may also be
linked to serious results.
In any case, it is important to follow the directions for usage.

Indicates that incorrect handling may cause hazardous
conditions, resulting in death or severe injury.

Indicates that incorrect handling may cause hazardous
conditions, resulting in medium or slight personal injury
or physical damage.

DESIGN PRECAUTIONS

• Some failures of the GOT or cable may keep the outputs on or off.
An external monitoring circuit sho uld 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.

• If a communication fault (including cable disconnection) occurs during
monitoring on th e GOT, communication between t he GOT and PLC CPU is
suspended and 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.

• Do not use the GOT as the warning device that may cause a serious
accident.
An independent and redundant hardware or mecha nical 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.

• Incorrect 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 POWER LED flickers (green/orange)
and the display section turns black and causes the monitor screen to appear
blank, while the input of the touch switch(s) 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 POWER LED flickers (green/orange) and the monitor screen appears
blank

DESIGN PRECAUTIONS

• Do 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 (3.94in.) apart.Not doing so noise can cause a malfunction.

MOUNTING PRECAUTIONS

• Be sure to shut off all phases of the external power supply used by the system
before mounting or removing the GOT to/from the panel.
Not doing so can cause the unit to fail or malfunction.

• Be sure to shut off all phases of the external power supply used by the system
before mounting or removing the option function board on to/from the GOT. Not
doing so can cause the unit to fail or malfunction.

MOUNTING PRECAUTIONS

• Use the GOT in the environment that satisfies the general specifications
described in this ma nual. Not doing so can cause an elect ric shock, fire,
malfunction or product damage or deterioration.

• When mounting the GOT to the control panel, tighten the mounting screws in the
specified torque range. Undertightening can cause the GOT to drop, short circuit
or malfunction. Overtightening can cause a drop, shor t circuit or malfunction due
to the damage of the screws or the GOT.

• Securely connect the option function board to the connector provided for the
board.

• When inserting/removing a CF card into/from the GOT, turn the CF card access
switch off in advance. Failure to do so may corrupt data within the CF card.

• When inserting a CF card into the GOT, push it into the insertion slot until the CF
card eject button will pop out. Failure to do so may cause a malfunction due to
poor contact.

• When removing a CF card from the GOT, make sure to support the CF card by
hand, as it may pop out. Failure to do so may cause the CF card to drop from the
GOT and break.

WIRING PRECAUTIONS

• Be sure to shut off all phases of the external power supply used by the system
before wiring. Failure to do so may result in an electric shock, product damage or
malfunctions.

• Please make sure to ground FG terminal of the GOT power supply section by
applying 100 or less which is used exclusively for the GOT. Not doing so may
cause an electric shock or malfunction.

• Correctly wire the GOT power supply section after confirming the rated voltage
and terminal arrangement of the product. Not doing so can cause a fire or failure.

• Tighten 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 the GOT.

• Exercise care to avoid foreign matter such as chips and wire offcuts entering the
GOT. Not doing so can cause a fire, failure or malfunction.

WIRING PRECAUTIONS

• Plug the communication cable into the connector of the connected unit and
tighten the mounting and terminal screws in the specified torque range.
Undertightening can cause a shor t circuit or malfunction. Overtightening can
cause a short circuit or malfunction due to the damage of the screws or unit.

TEST OPERATION
PRECAUTIONS

• Before performing the test operations of the user creation monitor screen (such as
turning ON or OFF bit device, ch anging the word device current value, changing
the settings or current values of the timer or counter, and changing the buffer
memory current value), read through the manual carefully and make yourself
familiar with the operation method.
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 accident.

STARTUP/MAINTENANCE
PRECAUTIONS

• When power is on, do not touch the terminals.
Doing so can cause an electric shock or malfunction.

• Connect the battery correctly. Do not discharge, disassemble, heat, short, solder
or throw the battery into the fire. Incorrect handling may cause the battery to
generate heat, burst or take fire, resulting in injuries or fires.

• Before starting cleaning or terminal screw retightening, always switch off the
power externally in all phases. Not switching the power off in all phases can cause
a unit failure or malfunction. Under tightening can cause a short circuit or
malfunction. Overtightening can cause a short circuit or malfunction due to the
damage of the screws or unit.
