Section 8 - Maintenance
WARNING
Ensure that you have fully read “Section 3 - Safety” before doing
maintenance procedures on the controller.
8.1 Clean the HMI Screen
The HMI screen should be cleaned, whenever required, with a moist, soft,
clean cloth and glass cleaner. The glass cleaner should be sprayed onto the
cloth and not directly onto the HMI surface.
The screen can be temporarily disabled to touch input by pushing the [Lock]
button on the bottom of the “7.22 System Settings Screen” on page 7-61.
This will disable the touchscreen input for 10 seconds.
The surface coating of the touch screen is resistant to the following solvents:
• Heptane • Unleaded gasoline
• Alcohol • Hydrochloric acid
• Toluene • Turpentine
• Acetone • Gear oil
• Methyl ethyl ketone
The surface is not resistant to 40% sodium hydroxide which will cause white
discoloration of the screen.
