Operating the touch screen

personal injury or damage to the machine or plant.
Take the following precautions:
• Never use the touch screen to control safety-related functions.
• Use a suitable touch pen to operate the touch screen.
• Calibrate the touch screen regularly.
• Switch off the device for cleaning and maintenance.
The following types of pressure are permissible:
● Using a plastic pen with a 1 mm radius at the point: 25 g.
● Using a silicone finger with a diameter of 1.6 cm: 50 g.
Note
Only touch one point on the touch screen and not several points at one time, as this may
trigger unintended reactions.
