Not doing so can cause the unit to fail or malfunction.
When connecting the battery, wear an earth band to avoid damage caused
by static electricity.
[MOUNTING PRECAUTIONS]
[DESIGN PRECAUTIONS]
[WIRING PRECAUTIONS]
Use the GOT in the environment that satisfies the general specifications
described in this manual.
Not doing so can cause an electric 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, short circuit or malfunction due to the
damage of the screws or the GOT.
When inserting a CF card into the GOT, push it into the insertion slot until the
CF card eject button pops out.
If not properly inserted, a bad connection may cause a malfunction.
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 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.
Remove the protective film of the GOT.
When the user continues using the GOT with the protective film, the film may
not be removed.
Operate and store the GOT in environments without direct sunlight, high
temperature, dust, humidity, and vibrations.
Some failures of the GOT, communication unit 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.
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.
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 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.
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
The display section of the GT12 is an analog-resistive type touch panel.
If you touch the display section simultaneously in 2 points or more, the switch
that is located around the center of the touched point, if any, may operate.
Do not touch the display section in 2 points or more simultaneously.
Doing so may cause an accident due to 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 shut off the
power of the GOT at the same time.
Not doing so can cause an accident due to false output or malfunction.
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 apart.
Not doing so noise can cause a malfunction.
Do not press the GOT display section with a pointed material as a pen or
driver.
Doing so can result in a damage or failure of the display section.
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.
[WIRING PRECAUTIONS]
[TEST OPERATION PRECAUTIONS]
[STARTUP/MAINTENANCE PRECAUTIONS]
Always ground the FG terminal, LG terminal, and protective ground terminal
of the GOT power to the protective ground conductors dedicated to the GOT.
Not doing so may cause an electric shock or malfunction.Terminal screws
which are not to be used must be tightened always at torque 0.5 to 0.8 N•m.
Otherwise there will be a danger of short circuit against the solderless
terminals.
Use applicable solderless terminals and tighten them with the specified
torque.
If any solderless spade terminal is used, it may be disconnected
when the terminal screw comes loose, resulting in failure.
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.
The module has an ingress prevention label on its top to prevent foreign
matter, such as wire offcuts, from entering the module during wiring.
Do not peel this label during wiring.
Before starting system operation, be sure to peel this label because of heat
dissipation.
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 short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to the damage of
the screws or unit.
Before performing the test operations of the user creation monitor screen
(such as turning ON or OFF bit device, changing 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.
When power is on, do not touch the terminals.
Doing so can cause an electric shock or malfunction.
Correctly connect the battery connector.
Do not charge, disassemble, heat, short-circuit, solder, or throw the battery
into the fire.
Doing so will cause the battery to produce heat, explode, or ignite, resulting in
injury and fire.
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.
Undertightening can cause a short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to the damage of
the screws or unit.
Do not disassemble or modify the unit.
Doing so can cause a failure, malfunction, injury or fire.
Do not touch the conductive and electronic parts of the unit directly.
Doing so can cause a unit malfunction or failure.
The cables connected to the unit must be run in ducts or clamped.
Not doing so can cause the unit or cable to be damaged due to the dangling,
motion or accidental pulling of the cables or can cause a malfunction due to a
cable connection fault.
When unplugging the cable connected to the unit, do not hold and pull from
the cable portion.
Doing so can cause the unit or cable to be damaged or can cause a
malfunction due to a cable connection fault.
Do not drop the module or subject it to strong shock. A module damage may
result.
[STARTUP/MAINTENANCE PRECAUTIONS]
[TOUCH PANEL PRECAUTIONS]
