Warnings for Design
D esigning switches that might cause human injuries and/or property damages on the touchscreen is strictly
prohibited.
Unintentional output signals due to malfunction of the main body, units, and/or cables, etc. can cause serious
injuries. Please design the system so that switches with major functions are equipped on device other than the
EMP.
Designing equipment safety related switches on the touchscreen is prohibited
For safety related switches, such as emergency stop switches, use a hardware switch from a different system.
Design the system so that the machine will not malfunction due to communication abnormalities between the
EMP and the host controller.
Failure to do so may result in injuries to the human body or property damages.
Do not use EMP as a major warning system that may cause injuries/ serious property damages, and or production
stoppage. Control devices related to critical warning displays and warnings should be structured by an
independent, redundant hardware system or a mechanical interlock.
EMP is not intended for use for aircraft equipment, aerospace instruments, trunk line communication equipment,
nuclear power control equipment, and medical equipment that concerns life support, and or other equipment that
concerns high reliability and safety. It cannot be used for these purposes.
When using the EMP for purposes that concern high reliability and safety functions and accuracy such as
transport equipment (trains, automobiles, ship, etc.), crime/disaster prevention devices, various safety devices,
and medical equipment that does not concern life support, be sure to have safety features including redundancy
and false operation prevention measures incorporated into the entire system.
Display will black out when the backlight goes out. If mistakenly operated in this condition, it might result in
improper operation. Do not design touch-switches that might cause human injuries and property damages on the
EMP.
Following phenomenon as below will occur when the backlights go out:
(1) Display will go out even if the Backlight OFF function is not set.
(2) Display does not recover at touch after the backlight goes off while the Backlight OFF function is set.
Warnings for Handling
Do not modify/disassemble the EMP. Doing so may cause fire and/or electric shocks.
Do not use around flammable gas. Doing so may cause explosions.
Do not put any kind of liquid, such as water, or metal into the product. Doing so may cause fire and/or electric
shocks.
