Working with stainless steel surfaces

Cleaning guidelines
Further information on stainless steel surfaces:
● The surface should be properly ventilated.
● Keep the surface clean. Remove cleaners and food residue immediately. Always avoid
the return of food stuff splashes to the production process.
● If mechanical cleaning is necessary, do not use cleaning equipment made of metal.
– Clean with brushes made of plastic or natural bristles or with microfiber pads.
– Use plenty of water to clean the surface.
– Make sure that the cleansing agent is completely removed without any residue.
● Make sure surface is not damaged: Do not damage the device during operation, or by
cleaning or repairing it using hard tools, in particular tools made of corrodible materials.
● Ensure that the surface does not come into contact with parts that can rust.
This includes water pipes, filings, residue from wire brushes or steel wool. These, as well
as rust films have a corrosive effect on parts made of stainless steel.
– Remove any stains or rust immediately.
– Remove new rust spots with a mild abrasive detergent in order to prevent any further
– Rinse thoroughly with clean water after each cleaning.

Clean screen for Touch HMI devices

The touch screen of the HMI device can be cleaned when it is switched on and a project is
running. An operating element must be available in the project that can be used to call the
"clean" screen. Once the clean screen is activated, touch screen operation is locked for a
configured period of time. Depending on the software setting, the lockout time can be
between 10 and 300 (default setting 30) seconds. The time remaining for the lockout is
indicated by a progress bar.
