SAFETY PRECAUTIONS

SAFETY PRECAUTIONS (Be sure to read these instructions before using this product.) 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 "WARNING" and "CAUTION". 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 minor or moderate injury or property damage.

Note that the caution level may lead to a serious accident 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] WARNING Some failures of the GOT, communication unit 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. Failure to observe this instruction may result in an accident due to incorrect output or malfunction. 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, GS25] The POWER LED blinks (orange/blue), the display section dims, and inputs by a touch switch are disabled. [GT2105-Q] The POWER LED blinks (orange/blue), and the display section dims.

However, inputs by a touch switch are still available. [GT2107-W, GT2104-R, GT2104-P, GT2103-P] The display section dims. However, inputs by a touch switch are still available. Even if the display section dims, inputs by a touch switch may still be available. This may cause an unintended operation 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. (This system signal is not available on GT2107-W, GT2104-R, GT2104-P, and GT2103-P.) 1

SAFETY PRECAUTIONS

[DESIGN PRECAUTIONS] WARNING 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, GS25] Do not touch two points or more simultaneously on the display section. Doing so may operate the switch located around the center of the touched point, 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 and GT25 only): The GOT becomes inoperative. Power on the PLC CPU again to reestablish communication. 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. To maintain the security (confidentiality, integrity, and availability) of the GOT and the system against unauthorized access, DoS *1 attacks, computer viruses, and other cyberattacks from unreliable networks and devices via network, take appropriate measures such as firewalls, virtual private networks (VPNs), and antivirus solutions.

Mitsubishi Electric shall have no responsibility or liability for any problems involving GOT trouble and system trouble by unauthorized access, DoS attacks, computer viruses, and other cyberattacks. *1 DoS: A denial-of-service (DoS) attack disrupts services by overloading systems or exploiting vulnerabilities, resulting in a denial-of-service (DoS) state. 2

SAFETY PRECAUTIONS

[DESIGN PRECAUTIONS] CAUTION 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. When the GOT connects to an Ethernet network, the IP address setting is restricted according to the system configuration. When a GOT1000 series model is on an Ethernet network, do not set the IP address 192.168.0.18 for the GOT and the controller on this network.

Doing so can cause IP address duplication at the GOT startup, adversely affecting the communication of the device with the IP address 192.168.0.18. The operation at the IP address duplication depends on the devices and the system. When using the Ethernet interfaces, set an IP address for each interface to access a different network. Failure to do so can cause a communication error on the GOT. Turn on the controllers and the network devices to be ready for communication before they communicate with the GOT. When the GOT is subject to shock or vibration, or some colors appear on the screen of the GOT, the screen of the GOT might flicker.

[MOUNTING PRECAUTIONS] WARNING Be sure to shut off all phases of the external power supply used by the system before mounting or removing the GOT main unit 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 unit onto/from the GOT.
