Human ‐ Machine ‐ Interface (HMI) Touch Screen
This HMI touch screen displays operation messages so that the operator is able to understand the
system condition. It also provides different operating modes and selections for the operator to work
with. During a cutting job, the operator can still enter the system and make changes to the cutting
operation as needed.
Do not wipe or clean the screen with volatile solvents.
Do not overexert pressure on the screen. The touch screen is very sensitive; all buttons on the
screen just need a slight touch to operate.
All range parameters in HITECH 5.7” are configured under the “manual” mode.
Please pay attention to the following environment conditions necessary for HITECH 5.7” HMI
touch screen to properly operate:
