# BLUE Precautions

The following precautions allow you to use BLUE safely. Carefully read this manual and all related manuals to understand the correct operation and features of BLUE.

WARNING
UNINTENDED EQUIPMENT OPERATION Touch panel switches should not be used to make a switch that could result in human injury or equipment damage. Trouble with the display unit, units, and cables which keep the output ON or OFF could result in a serious accident. An output signal that could result in a serious accident must be equipped with a monitoring circuit such as a limiter. Please design the system so that important operation switches are handled by equipment other than the display unit. This will prevent potential accidents as a result of incorrect output or malfunctions. Touch panel switches should not be used for a device's Emergency Stop Switch. The Ministry of Health, Labor and Welfare requires all industrial machinery/systems must be equipped with a mechanical, manually operate emergency stop switch. Also, for other kinds of systems, similar mechanical switches must be provided to ensure safe operation of those systems. Failure to follow these instructions can result in death, serious injury, or equipment damage.
