1.11 Keypad Front
Operating the keys with hard items (e.g. screwdriver) reduces their service life.
1.12 Keyhook
For reasons of operational reliability, it is not permitted to deinstall the Keyhook
tool. This tool prevents malfunctions occurring if more than key is pressed
simultaneously.
1.13 TFT LC Display
The permanent display of a screen containing bright picture information can
lead to a "burn in effect" in the case of an LC display.
If a screensaver is used, observe the following:
• The following applies in the case of screensavers which switch off the back-
lighting:
each time it is switched on reduces the service life of the back-lighting by
approx. 50 min.
•
If screensavers are used which activate black when the back-lighting is
switched on (e.g. starfield simulation / flying stars) the liquid crystals could
regenerate. Observe the service life of the back-lighting.
Depending on the use, it is necessary to weigh up the pros and cons of
implementing of screensavers which regularly switch off the back-lighting or the
continuous display of the customer's application.
1.14 Installation of the Panel PC in the Housing/Switching
Cabinet
Note
The air intake temperature for the computer unit (interface side) must not
exceed 45 °C. The basis for this is the temperature measured a distance of 10
cm from the air inlet slots (interface side) of the computer unit. The Panel PC
must be a minimum of 10 cm from the housing on the air inlet side (fan).
Please pay particular attention to this when dimensioning for closed housing.
Caution
Applies to Panel PCs installed in a swivel arm housing.
Avoid any fast or jerky movements of the swivel arm during the operation since
such movements may cause serious damage of the hard disk.
