NoteNotes on operation of the touch-sensitive glass surface with multi-finger operation functionusing gesturesObserve the following notes in order to avoid incorrect operation of the touch-sensitive glasssurface with multi-finger operation function. Otherwise, entries made at the device will either beincorrectly identified/implemented - or not at all.● The OP 015 black does not support safety-relevant functions and these may also not beimplemented in the touch-sensitive glass surface.● The touch-sensitive glass surface reacts to contact with its surface, not to pressure.Therefore, do not subsequently attach a protective film to the touch-sensitive glass surface.Also remove all protective and packaging films, as these have a negative impact/preventdata from being entered and initiate incorrect operator entries.● Only operate the touch-sensitive glass surface with your finger tips, not with your fingernails.● Touch the touch-sensitive glass surface either perpendicularly or at a maximum angle of 45°to the surface.● Avoid unintentional multiple touches, e.g. with the knuckles or by leaning on or against thedisplay.● Make sure that the surface of the touch-sensitive glass screen does not get dirty. Cleaninginformation can be found on the Internet in the following article in the Service & Supportportal of Siemens Industry:http://support.automation.siemens.com/WW/view/en/39718397.Always check whether the executed operator actions have been recognized by the device.NotePlease observe the valid C standards for the particular machine type (e.g. for turning machines:EN ISO 23125-2010, pages 36 and 49). These state that a button that initiates motion with theprotective door open must be implemented using an additional acknowledgment device; this isbecause for single-channel keyboards – such as the OP 015 black – generally no PL(performance level) "d" can be achieved.Displaying the TCU menuTo display the TCU menu, simultaneously touch the left-hand and right-hand lower corner ofthe active display area in order to display the TCU menu.If you have connected a USB PC keyboard to the OP 015 black, you can also display the TCUmenu by simultaneously pressing keys F9 and F10.GlovesDo not wear thick gloves, such as work gloves, when operating the touch-sensitive glasssurface. You can wear thin gloves made of cotton or gloves for touch-sensitive glass surfaceswith capacitive touch function.You can wear the following gloves for operating the touch-sensitive glass user interface of theoperator panel:● Dermatril L● Camatril Velours Art. 730Description2.2 Operator controls and displaysOperator panel front: OP 015 black16 Manual, 05/2019, A5E35227814B AB
