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
